Ayurveda – The Science of Life

Ayurveda – The Science of Life

by | Aug 11, 2021 | Health and Healing

Ayurveda literally means ‘science of life’. It is one of India’s many indigenous healing traditions. But it is not a science in the western sense of the word. Very much unlike western science, Ayurveda is said to have been divinely revealed.

Ayurveda has ancient roots, dating back at least 5000 years. According to legend, one day, a long, long time ago, the wisest Brahmans came together to meditate on matters of sickness and health, nutrition and well-being. And thus, the Ayurvedic philosophy and the principles of health were conceived in their entirety.

 

 

Balance as a dynamic principle

Ayurveda’s fundamental premise is the unity of body, mind and spirit and the interconnectedness of all life. Health means ‘wholeness’, and the key to health is a balanced lifestyle.

A balanced lifestyle means moderation in all things – physical, mental and spiritual. Imbalance in any sphere of life will eventually affect all aspects of the body-mind. A balanced diet is just as important as being happy and physically fulfilled.

But we are constantly exposed to an interplay of forces that can easily upset our balance. To maintain balance means having to dynamically adapt to ever-changing circumstances.

 

 

Elemental Balance

These interacting forces were conceived as the ever-changing dynamic expression of the elements (fire, air, earth, water and ether).

The Ancients regarded the elements as ‘qualia’. When they spoke of fire, they did not mean an actual bonfire but the essence of fire, expressed in the heat, the flickering flames, and their all-consuming power. The construct of the elements is based on a phenomenological way of perceiving and interpreting inner and outer reality.

Everything in the universe has its own elemental signature composed of a specific energetic pattern. And all living things are interconnected. Herbal remedies and are employed to correct the energetic imbalance.

Constitutional types

Human beings are categorized into three basic constitutional types known as doshas: Vata, Pitta, and Kapha. Although all three doshas are present in every person, one or two usually dominate.

Vata

Vata is associated with the elements of air and ether.
It implies movement and changeability, and its quality is cold and dry. Excessive Vata energy manifests as nervousness and anxiety. Vata individuals find it hard to sit still. They are always on the move. Their minds are quick and active, but they do not always retain information very well. The skin or hair tend to be dry and brittle, and they often complain about cold hands and feet. Their body frame tends to be light and skinny.

Pitta

Pitta is associated with the elements of fire and water. It expresses itself as the assimilation of food and the heat of metabolic processes. It describes a hot temperament that requires plenty of food to fuel the metabolism. The intensity of the inner fire tends to turn Pitta types’ hair grey or causes them to lose it at a young age. The hair and skin are often oily, and Pitta-individuals frequently have strong body odours. Their cognition and memory are usually sharp, but they often have a perfectionist streak. This can lead to a judgmental and over-critical attitude towards others. Pitta-types often have a need to dominate and control.

Kapha

Kapha is associated with the elements of water and earth. It represents structure and substance. In the body, it finds expression in the bones and connective tissues. Kapha energy is heavy and cold. Kapha individuals have heavy body frames and a tendency to put on weight. They move and think slowly and can be lethargic. The skin may feel cold and clammy, and they often have a sweet tooth. Kapha individuals can be kind and compassionate, but they may be overly attached and suffer from jealousy.

We are constantly subject to external forces that can unbalance our equilibrium. Ayurveda aims to rectify symptoms of dosha imbalance. Its tools are mental and physical exercises (e.g. meditation, yoga), medicinal herbs, and appropriate nutrition.

 

ayurvedic medicineFoods are also categorized into three basic types:

  • Sattva – milk and plant products, mild flavours
  • Raja – hot and spicy food, meat
  • Tamas – denaturalized foods, canned food, fast food, alcohol

 

Whether foods are healthy or harmful depends on the person’s dosha constitution.

 

Correcting excessive Vata energy

To balance excessive Vata energy, eat cooked food that is oily, heavy and warm, and preferably sweet, sour or salty. Refined sugars and yeast should be avoided. Vegetables of the cabbage and potato family are not recommended. Raw vegetables are okay, but should be marinated or served with a dip or dressing. Avoid just grabbing food on the go. Eat slowly and keep regular dinner times.

Correcting excessive Pitta energy

Excessive Pitta energy can be balanced by eating a predominantly vegetarian diet consisting of plenty of fruit, veggies and grains. Overly spicy or acidic foods and excessive amounts of salt, oil or alcohol should be avoided.

Correcting excessive Kapha energy

To balance excessive Kapha energy, eat light, fresh, raw vegetables and fruit. Sweets, creamy foods, nuts and heavy carbohydrates should be avoided. Spicy foods are beneficial as they stimulate metabolic processes. But meat, dairy products and citrus fruits and sweet, sour and salty foods should be avoided.

Obviously, these are only the most rudimentary guidelines. To learn more about the principles of Ayurvedic nutrition, see the recommended books or find an Ayurvedic practitioner near you.

Other causes of disease

Ayurveda also recognizes other causes of ill-health that call for different types of treatment.

Accidents:

Physical or mechanical injuries, such as broken bones, call for surgery.

Inflammation:

Infectious diseases and organ dysfunction are mostly treated with herbs and other curative substances.

Afflictions of the soul:

Emotional issues such as fear, hatred, apathy, or jealousy.
Such issues are treated therapeutically. (Aromatherapy, colour therapy, music therapy, charms, dance etc.)

Natural causes:

Old age, hunger and similar are treated with spiritual measures such as meditation, prayer and spiritual practices.

Western science has long struggled to understand these ancient and often confusing systems of correspondences and typologies. They are often labelled unscientific and quickly dismissed. Such philosophies are considered mumbo-jumbo simply because they do not fit the reductionist paradigm. Some modern Ayurvedic physicians have attempted to translate their system into western concepts to gain more acceptance and make it easier to understand.

But Ayurveda has gained popularity in recent years. -no longer a ‘fringe’ therapy, Ayurveda has a firm place in the field of alternative and complementary therapies. No one needs to travel halfway across the world to consult an Ayurvedic practitioner (although many do!)

 

Can culturally alien medical practices be effective, regardless of where and to whom they are applied?

This question deserves consideration.

In rural India, hygienic conditions, even at hospitals, cannot be compared to those in the West. Under such sanitary conditions, it is not always possible to administrate injections safely. At the same time, pharmaceuticals may be regarded with such awe that they are overprescribed, leading to unwanted results.

Although western medicine is universally considered superior to indigenous healing systems, it can fail if the environmental conditions are inadequate. Likewise, Ayurvedic medicine, in the hands of insufficiently trained practitioners, may not produce the expected results. Neither system can simply be transposed to another culture without taking systemic factors into account.

Ayurveda has been practised successfully for thousands of years. But it takes years of study, including the philosophical premise on which it is based. Reducing it to some basic principles does not do it justice and will not produce the desired results.

What Gardening Jobs are there to do in August?

What Gardening Jobs are there to do in August?

by | Aug 4, 2021 | Gardening

August is a fabulous time for all gardeners! The explosion of colour, scent and texture is a fiesta for the senses. But above all, allotment gardeners love this time of the year. Harvest is finally here. Finally, all the hard work from the spring is paying off.

 

Harvesting

Just what you will harvest now depends on what you sowed earlier. I tried to grow carrots this year (again). Alas, to no avail. I don’t know what it is about me and carrots, but I have never managed to grow them – except a stray one that is volunteering among the Basil, in one of my balcony planters. If you had better luck, you are probably feasting on them right now.

Fortunately, my other crops are doing fine. There are runner beans and courgettes to pick, almost daily. Peas are over, but the tomatoes are now kicking in.

Perhaps you are picking cucumbers and early potatoes, as well as onions and shallots. The beetroots are swelling here, but yours might be ready to pick. Spinach is now past its best, but Swiss chard picks up the slack. I love the colourful varieties best, although they all make excellent and versatile summer greens.

 

Sowing winter vegetables

You might find that picking and processing all those fantastic summer veggies is enough of a job, and nothing could be further from your mind than winter’s approach. But, beware, it’s August, and before long, summer will be over. So, now is the time to start thinking about late crops and veggies you would like to overwinter.

In milder climates, it is well possible to extend the season to the end of October. The cabbages are particularly hardy. If you started some earlier, you can now plant them out into their permanent positions. You can even still sow some: kohlrabi or turnip and some spring cabbages (check your seed package). Cabbages are particularly popular with bugs and caterpillars, so you might want to protect young seedlings with a fine-meshed cloth. Plant the seedlings out once they have developed 5-6 true leaves. Remember that they will grow big, so give them plenty of space. They also need a sunny spot and do best in a bed that had a different crop in it the previous year (no brassicas!)

I have not had much luck with cabbages. The caterpillars and whiteflies always get the better of them. I prefer growing Asian salad greens, which are easy, prolific and not as vulnerable to bugs. They are hardy, too. Alternatively, spinach and corn salad will also provide welcome winter greens when little else is available.

 

Salad ingredients

Some fast-maturing crops can also now be sown again, such as Rocket, Mustard greens, and Radishes. Spring onions can also be sown in late August, but won’t be ready to pick until the following spring.

 

Watering

Make sure you water regularly and deeply. A little sprinkle does not reach the deeper roots. Instead, it encourages superficial root growth close to the surface. Mulch well to keep the moisture in the soil. Feed with compost or diluted liquid manure.

 

Wildlife

Don’t deadhead all the flowers just yet. The birds are looking for food! They also appreciate a source of clean water for a drink or a bath. The hedgehogs will make use of it, too. Bushes with berries, such as Cotoneaster or Hawthorn, are popular bird food. Starlings and blackbirds just love them!

The Cultural History of Grapes

The Cultural History of Grapes

by | Jul 28, 2021 | Plant Profiles, Food, Plants & People, Trees, Uncategorized

Grapevine (Vitis vinifera)

Grapes are one of the most important agricultural crops in the world. But they have far more uses than ordinarily meet the palate. There are at least 8000 cultivated varieties of grapes, most of which are grown in the Northern Hemisphere.

Name: Grapevine (Vitis vinifera)
Family: Vitaceae
Synonyms: Grapevine, Vigne, Weintrauben, Rebstock

 

Description:

Grapes are one of the most important agricultural crops in the world. From New Zealand to California, Chile, South Africa and of course, their traditional turf around the Mediterranean Basin, grapes are cultivated in Mediterranean climate zones around the world. Grapevines are surprisingly hardy. They can live on next to nothing. They thrive on poor soils, so long as they are well-draining and don’t mind the heat. The only thing they won’t survive is a cold, wet climate.

When left untended, grapevines can reach a height of about 15 m. As climbers, they will scramble up anything that will give them support. In cultivation, they are often trained on wires and cut back after each season so that only the strongest one or two shoots remain.

The gnarly stem forms finely grained, dense wood. The leaves are palmate (hand-shaped) with deeply indented lobes, with very jaggy serrated margins, depending on the variety. In May or June, they begin to flower, forming bunches of tiny, white, 5-petaled flowers with a very delicate and sweet aroma. Alas, this phase does not last long. Soon, bunches of sweet, juicy berries start to develop.

Depending on the variety, their size and colour vary. The smooth-skinned, yellowish-green to reddish, or purple-black berries usually contain 2 seeds each (except for seedless varieties). Vines can be propagated by seed or cutting. Most European stocks are grafted onto American rootstocks due to a devastating blight that nearly destroyed all European vine stocks.

There are also many wild grape species, which also tend to be a meandering bunch. They can sprawl over an extensive area if left undisturbed. Their berries also grow in bunches, but they are much sparser and consist of much smaller berries, which are usually quite tart. Like their cultivated counterparts, the flowers are small and rather inconspicuous.

Chile Wine Valley

Fancy a Wine tour of the Chilean Central Valley?

The Central Valley is Chile’s most famous wine-growing region. Situated between the Andes and the Pacific, enjoy not only great wines and food, but also stunning views all the way! This short self-drive itinerary explores the Colchagua Valley, which is close to Santiago. Combine with a short trip to the coastal resort town of Pichilemu, known for its water sports activities.

Distribution:

The geographical origins of the vine is still a matter of debate. Various wild varieties can be found in different parts of the world, far beyond the Mediterranean. When the Vikings first arrived in the Americas, they called it ‘Vinland’ for the many wild grape varieties they found there. The type now under cultivation in Europe seems to have originated in Georgia. Under the influence of Greek and Roman expansion, it steadily spread west and north from there. Today grape production is prolific in all warm, temperate regions of the world, from Central and Southern Europe, Northern Africa, Asia Minor, US, Chile, Argentina, South Africa, Australia, to New Zealand.

Problems and Pathogens:

Viticulture is a profitable business, which, however, claims a vast amount of land. Wine lovers may appreciate the variety of tastes and textures this diversity produces, but environmentally it is a disaster. Relying almost entirely on just one single cash crop is highly risky. Furthermore, monocultures heavily depend on fertilizers, and pesticides that are highly damaging to the environment.

Various pathogens can threaten grapevines: powdery mildew rots the stalks, shrivels the leaves, splits the grapes and finally kills the vine. Red spider mites suck the sap from the leaf veins, phylloxera vastatrix strikes the roots, and the cochylis moth grub attacks the flowers.

HISTORY, MYTHOLOGY AND FOLKLORE

The story of viticulture is so old that nobody really knows where and when it all started. The Bible mentions that Noah planted a vineyard, but even he was probably not the first. Wine is mentioned in almost every classical text, with records dating back some 6000 years.
It appears as though the Greeks were the first to popularize fermented grape juice, with the Romans soon following suit. As major trading powers, they spread the art of viticulture all around the Mediterranean Basin. By 600 BC, wine was a sought-after export commodity, especially popular with the Gauls who, in time, became expert growers themselves.
However, in the latter half of the 18th century, tragedy struck. By then, grapes had moved to the Americas along with the colonists. The drama unfolded when a North American grower sent some specimen of his rootstocks back to the old world for further study. Unfortunately, the sample he sent was infested with a devastating blight (phylloxera vastatrix) that threatened to wipe out vineyards across Southern Europe. It was a catastrophe of unprecedented proportions.
Luckily, the cure also came from North America – and just in time. A frantic search for a blight-resistant yielded results, and another sample was sent to Europe. Growers started quickly grafted their ancient varieties onto American rootstocks, which saved them. Although the industry took some time to recover, European wine-growers rank again at the top of the international charts.

The wines of Ancient Greece seemed to have been quite a different kind of brew than what we are used to today. Historical records describe a much thicker and heavier beverage that had to be diluted at a ratio of 1:3 for consumption. Typically, it was infused with other substances such as resins, aromatic herbs and even psychotropic plants. It is not surprising then that the Greeks associated wine with Dionysus, the wild, shamanic god of ecstasy. His rites were frenzied and orgiastic. A menacing mob of Maenads, (his priestesses) pursued the god (or his representative) in a feverish hunt and tore him apart. Eventually, an animal (a fawn or fox) replaced the human sacrifice. In time, Dionysus was tamed and re-cast as a chubby, cheerful, but domesticated deity of wheat and wine. The animal sacrifice was replaced with a ritual sharing of ceremonial bread and unadulterated wine during the annual celebration of the Elysian Mystery play.

The Romans equated Dionysus with Bacchus, their god of wine and intoxication, whom they worshipped in much the same manner. In Egyptian mythology, Osiris is the Lord of wine, and Isis fell pregnant with Horus after eating his grapes.

The Hellenized Syrian satirist Lucian recounts a ‘tall satirical tale’ in his ‘True History’. A strange vineyard once grew on the far banks of a river that ran with wine instead of water. The grapevines grew woody stems, but their upper parts sprouted beautiful maidens whose hair was a tangle of leaves and bunches of grapes growing from their fingertips. Their enchanting song lured passers-by. But woe to those who succumbed to their embrace: instantly drunk and unable to escape, the hapless took root and soon sprouted shoots and leaves themselves.

Aphrodisiac associations:

Wine is a divine gift of the gods. In moderate amounts, it lifts the spirit, exhilarates and inspires. It opens the mind and holds the key to the heart and soul. Innumerable works of art have been inspired, and countless adventures started by a spark of its passionate fire. But in excessive quantities, it stupefies and causes delusion. It is a fine line between ecstasy and frenzied oblivion.

 

Ever tried making homemade wines?

MEDICINAL USES

Both red and white wine was traditionally used as a solvent to extract other substances when making medicinal wines and cordials. But various parts of the plant itself were also used as medicine.

PARTS USED:

Leaves: fresh young leaves
Flowers: dried or fresh flowers
Berries: fresh or dried fruit
Seeds: oil pressed from the seeds

HARVEST TIMES:

The flowers appear in May/June. The leaves should be picked in spring when they are tender, and the grapes ripen from September onwards (in the Northern Hemisphere).

LEAVES

Constituents:
In the summer, the leaves contain a mixture of sugar and glucose, tartaric acid, potassium bi-tartrate, quercetin, quercitrin, tannin, Amidon, malic acid, gum, inosite, a crystallizable fermentable sugar and oxalate of calcium. In the autumn, they contain more
quercetin and less quercitrin.
Actions:
Anti-inflammatory, astringent, styptic
Indications:
An infusion of 1 TSP of fresh, finely cut leaves per cup of water helps with conditions such as rheumatism, gout, nausea and spitting of blood. A preparation known as ‘Papinorum Extract’ made from the leaves is used in Homeopathy to treat epilepsy and inflammatory conditions of the hip. Dried and powdered, leaves were fed to cattle as a treatment for dysentery. A decoction was used to prevent a threatened miscarriage. The astringent properties help to arrest internal and external bleeding, cholera, dropsy, diarrhoea and nausea. The decoction can also be used to treat mouth ulcers and as a douche for vaginal discharge. Grape leaves are used as a treatment for varicose veins and fragile capillaries. For this purpose, leaves are harvested as soon as they turn red and are used either fresh or dried.

FLOWERS

Actions:
Nerve tonic
Indications:
1tsp of dried flowers per cup of boiling water is said to strengthen neuronal dendrons. It also supports the bone marrow to build red blood cells. The infusion can be used internally or applied externally as a rub to aid neuronal function (even for numbness of the lower limbs)

BERRIES

Constituents:
Malic, tartaric, ascetic ascorbic and racemic acids, alanine, alpha-linolenic acid, alpha-tocopherol, arginine. Oxalic acid in unripe fruits, Ca, P, Fe, thiamine, riboflavin, niacin, and ascorbic acid
Actions:
Fortifying blood tonic, nourishing, stimulates kidney and liver function and thus aids elimination and inner cleansing, gentle laxative
Indications:
A grape-fast is a popular method to rid the body of accumulated metabolic waste products and other toxins. 2 kg of grapes should be eaten throughout the day for two weeks, with little or no other food. It is recommended to do a full day fast one day before embarking on this regime. This is an excellent way to stimulate and tone the kidneys and thus to lose weight by releasing water from the tissues. It reduces fat, regulates bowel function, purifies the blood and cleanses the skin. A grape-fast can alleviate rheumatic pain and heartburn, regulate metabolic processes, water retention, oedema and circulatory complaints. Grapes are restorative and nourishing food that aid recovery from anaemia and debilitating conditions. Dehydrated grapes (raisins) have demulcent, nutritious and slightly laxative properties. Grape sugar (fructose) is rapidly absorbed into the bloodstream. It almost instantly restores energy levels in case of exhaustion and debility.
 Contraindications:
A grape fast is not recommended for dyspeptic, excitable, hot-blooded individuals, as it may cause palpitations.

SAP:

Grapevine sap, a watery substance that naturally occurs when pruning the vines, was used as a lotion to treat weak eyes and corneal floaters. It has also been used as a skin lotion. Internally, it acts as a diuretic.

GENERAL USES

  • Basketry: The annual shoots are pruned in the winter. They are very flexible and have been used for basketry and broom-making.
  • Cosmetics: A lotion made from the flowers has been used for freckles, while the oil (seeds) is used for making soap.
  • Dyes: The berries yield a purplish colour, which is not durable. The fresh or dried leaves dye yellow.
  • Fuel: The old grapevine stocks are popular as firewood, especially for grilling due to the aromatic smoke. The twigs make good kindling.
  • Grapeseed Oil: Grapeseed oil is pressed from the seeds. It is used for culinary and cosmetic purposes. For culinary use, the oil must be refined to make it fit for consumption. Unrefined grapeseed oil is slightly sticky. As a massage oil, it is best to blend it with other oils.
  • Culinary uses: Grapes are wonderfully refreshing, nourishing and cleansing fruits that can be enjoyed straight from the vine. Their sweet and tasty juice makes a refreshing beverage and can also be used to make jelly. Evaporated to produce a concentrate, it makes a good sweetener. But above all, grape juice is fermented to make wine and champagne. Wines come in a staggering variety: reds, rose or white wines, champagne or sparkling wine, are made from hundreds of different grape varieties. A dessert wine is produced by adding alcohol to the ferment to prematurely stop the fermentation process.
  • The young tendrils can be eaten raw or cooked as a vegetable. The flowers are also edible and can be prepared as fritters.
  • The sap tastes sweet and can be used as a drink, but harvesting large quantities weakens the vines. Roasted seeds can be used as a coffee substitute.
  • Pickled leaves are used as a wrapping for finger-food appetizers (dolmas) that are especially popular in Greek and Middle Eastern cuisines.
  • A crystalline salt, cream of tartar, also known as potassium bitartrate, is derived from the residue of pressed grapes. Sediments collected from wine barrels are used for making baking powder.

Plant Profile: Moringa

Plant Profile: Moringa

by | Jul 22, 2021 | Plants & People, Plant Profiles, Trees

Plant Profile: Moringa (Moringa oleifera Lam.)

Moringa is a tropical tree that is not very well known outside its native habitat, despite offering multiple gifts for the benefit of mankind.

 

Habitat:

Moringa has spread from its native habitat in the sub-Himalayan region of India to tropical and subtropical areas around the world. It is now cultivated on many continents. It is highly adaptive and tolerant to even the most inhospitably arid soil conditions. Prolonged cold spells with temperatures falling to below 20 °C are the only conditions it can not tolerate. Its preferred conditions are temperatures between 25°-30 °C and well-draining soil.

 

Description:

Moringa is a fast-growing subtropical tree native to the Himalayan foothills. In as little as 10 months, it can grow to an astonishing height of three meters – from seed! However, it rarely grows to more than 10 meters in total – a tree of medium stature.

Its feathery leaves and bean-like seed pods give it the appearance of a legume species. But that is not the case. Moringa is the only genus of the Moraginacae family, which comprises 13 species. The pods, which are slightly thickened at one end, are known as ‘drum sticks’. Each pod contains 15-20 winged seeds.

The tree branches freely and produces dark, green feathery tri-pinnate leaves with elliptical leaflets. The flowers grow in bunches of small white or cream-coloured flowers and have a subtle fragrance.

Moringa Blossom

 

History

Moringa is one of the most important and universally useful plants of the tropics.

The entire plant is edible – leaves, seeds, pods, flowers and even the roots – although some experts warn against eating them. (The British called this tree ‘Horseradish root tree’, an allusion to root’s distinct flavour).

Moringa is remarkably rich in essential nutrients such as vitamin A, C and E, calcium, potassium, iron and, perhaps most importantly, protein. It is recommended as a nutritional supplement for pregnant women, nursing mothers, children, and the elderly and infirm. It is one of the few sources of high-quality vegetable protein that contains all essential amino acids.

In India, the young, green and immature pods (the ‘drumsticks’) are a popular ingredient of curries. The seeds yield a high-quality oil used in cooking which is rich in oleic acid. It is very stable, comparable to olive oil in terms of resistance to rancidity and nutritional value. The leaves are the most perishable. Ideally, they should be consumed within a couple of days of harvest. To extend their shelf-life on the market, they need to be bagged and cooled. Alternatively, their nutritional value can be better preserved by drying and powdering them. The powder can then be added as a nutritional supplement to soups, beverages, curries and other foods. But the most miraculous powers are contained within its seeds: Moringa seeds act as ‘flocculants’. They can purify water by causing contaminants to ‘flock together’ and precipitate, i.e. sink to the bottom of the vessel, thus effectively purifying the water. Pharmacologists at Gadja Mada University in Indonesia showed that “one crushed Moringa seed can clear 90% of the total coliform bacteria in a litre of river water within 20 minutes. While an animal study showed that even 2,000 seeds per litre of water had no toxic effects on mice.”

This is powerful and important indeed, especially given the poor water quality in many tropical and subtropical parts of the world. Given that access to clean drinking water is still a problem in many tropical regions, Moringa offers hope. Promoting the planting of Moringa trees could significantly improve water quality, as well as help to boost nutrition in some of the poorest regions of the world.

Medicinal uses:

Medicinally, Moringa is primarily used to address problems arising from malnutrition. It has a tonic effect on the gastric system and can cure diarrhoea. Thanks to its high vitamin A content, it is a great immune system booster. Vitamin A also helps alleviate visual problems, such as night blindness and xerophthalmia.

Despite its impressive nutritional profile, Moringa can not cure severe malnutrition. The body can no longer process iron, protein or fat once severe physiological abnormalities have been triggered (e.g. infections, impaired liver and intestinal function, imbalance of electrolytes and related problems). However, Moringa is the best available ally to prevent such severe cases and correct mild and moderate ones.

Moringa can also reduce blood sugar levels and thus help control diabetes and high blood pressure. Furthermore, it is said to be helpful in the treatment of respiratory problems, tuberculosis and malaria.

The raw seed pods act on the liver and are used as an anthelminthic (deworming) agent.

The seed oil contains antibiotic and anti-inflammatory compounds. It is used in the treatment of bacterial and fungal skin conditions. Topically, it can be applied to aching joints.

Recent research suggests that Moringa may be effective against certain kinds of cancer, particularly skin cancer. Traditional healers have long used Moringa for this purpose, but further studies are needed to evaluate and verify these traditional uses. They also claim that it to be an excellent nutrient to prevent cancer.

It is easy to add Moringa to the diet, and almost anybody could benefit from it. But above all, it should be used to improve the conditions of those who live in extreme poverty. Moringa should be planted in every available patch of public land to make it accessible to all.

Plant Profile: Aloe vera

Plant Profile: Aloe vera

by | Jun 20, 2021 | Plants & People, Plant Profiles, Plants as Medicine

Aloe Vera is no longer an exotic stranger. We see it advertised as a popular ingredient in numerous household products, from washing-up liquid to latex gloves, and even razors. Many of us also know the plant itself.

Aloe Vera is an undemanding, perennial succulent, at home in arid regions of Africa. It is a distant cousin of the century plant, so common in the southwestern United States. Both belong to the order of Asparagales, but do not share the same genus.

Description:

Aloe Vera’s fleshy, succulent leaves contain a clear, gooey gel-like substance. The leaf margins bear ‘sharp teeth’ to deter casually browsing animals. It loves hot and dry conditions and only ‘wilts’ when over-watered, or exposed to freezing temperatures. Grown in the right conditions, (that is, mostly ignored), the plant will do just fine. It may even send up a central shoot with short tubular yellowish flowers sprouting from the upper part of the spike.

The Aloe genus comprises about 400 species, with Aloe Vera considered the most useful for medicinal purposes. Mature plants contain the most potent healing compounds.

Habitat:

Aloe Vera is native to arid regions of the north-eastern and southern parts of Africa and Madagascar. But thanks to its tremendous value as a healing plant, it has spread to arid regions throughout the world. Today it is widely cultivated around the world, including in North America, Japan and China.

Aloe vera plantation

History

Aloe Vera is a truly wonderful plant, with a well-established reputation as a medicinal plant, that is particularly useful for skin conditions, minor cuts, abrasions and burns. The dried latex, a well-known laxative, is distinct from the gel. It derives from a yellow juice that is contained in the pericyclic tubules of the inner leaf.

Although Aloe has been in documented use for at least 3500 years, there is a lot of controversial and contradictory information about it.
It was first mentioned in the famous Egyptian Ebers Papyrus, which dates back to 1500 BC and is widely regarded as one of the earliest documents on what was to become the western Materia Medica. More than likely, Aloe Vera’s use was well-established long before it was recorded. In the hot and dry countries of Northern Africa and the Middle East, Aloe Vera served as a soothing household remedy for sunburns and a ready-to-use moisturizing cosmetic lotion.

Some confusion surrounding this plant stems from the fact that it is still frequently mistaken for lignum Aloes or Wood-Aloes, which is an entirely different species of plant. Although abundantly mentioned in the Bible as an incense ingredient and constituent of embalming oils, Wood-Aloes does not grow in the Mediterranean Basin but is a tree of the genus Aquilaria. Also known as Agar wood, Wood Aloes is native to Southeast Asia. While Aloe Vera latex does transform into a hard substance when dried and is sometimes referred to as ‘Aloe resin’, it is not particularly aromatic and has never been used as incense.

Aloe Vera juice

In recent years, ‘Aloe Vera juice’ (as well as a myriad of spin-off products that contain the juice), has become popular. But by their very nature, products are always processed. Aloe Vera juice is no exception. It always contains flavourings and preservatives. In its natural form, Aloe juice (gel) is not very palatable – it is bitter and gooey – not exactly a pleasure to gulp down. It is not hard to see why the ancients didn’t recommend it and only saw it fit as an emergency measure for the treatment of intestinal parasites.

Careful handling is of utmost importance as oxidation sets in the minute the leaves are cut, and enzymatic activity begins to destroy some valuable compounds. Traditionally, the leaves are taken to a processing facility as quickly as possible after being cut, ideally in a refrigerated truck. At the processing plant, they are filleted by hand to remove the outer skin. Unfortunately, most of the beneficial compounds are concentrated just beneath, and filleting removes much of what makes the plant so valuable.

Aloe vera gel

Modern uses

Aloe Vera is best known for its use in topical skin-care applications. But commercial products are not quite as potent as the gel that can be squeezed from a freshly cut leaf, since the natural jelly-like substance is not very stable and deteriorates quickly upon exposure to the air. To preserve its properties and thus extend its shelf-life, manufacturers must process the gel. But processing rarely enhances a natural product. In the case of Aloe Vera, it reduces a ‘miracle plant’ to a mediocre substance with vastly diminished benefits.

This back-story sheds some light on some rather puzzling research results: Aloe Vera’s glowing reputation in folk medicine is not confirmed by research results under laboratory conditions. The reasons for this are a bit complex and are partly due to the lab conditions and partly to the processing methods that are used to ‘preserve’ the gel or to extract its ‘active compound’.

But plants are highly sophisticated when it comes to their biochemistry. Their healing effect is often not due to one simple compound but rather the result of complex interactions, or ‘synergy’ between a host of different compounds.

Conventional preservation methods involve pasteurization: heating the gel to a high temperature, thus destroying many of the more fragile components. Chemical preservatives are added, further adulterating the original substance. Understandably, the result is rather disappointing, leading researchers to conclude that Aloe’s benefits may have been exaggerated. But one could equally conclude that we simply lack proper processing methods to preserve the natural composition of fresh Aloe Vera gel.

Processing

In recent years, more efficient processing methods have been developed. A cold process that dissolves the green cellulose parts of the leaf, leaves the biochemical activity of the gel substance intact, including the aloin, a yellow bitter laxative compound that is found just underneath the outer skin. Additional processing involves adding various anti-oxidants, as oxygen initiates the deterioration and breakdown of the gel and promotes the development of aerobic bacteria. Finally, the pulp is separated from the liquid part, a carbon compound is added to help filter out the aloin. The carbon compound is subsequently removed. In the last step, the liquid is exposed to ultraviolet light that destroys any bacteria.

This method still requires stabilizing compounds to be added to the final product, but it is a great improvement to conventional extraction processes, which only processed the gel and relied on heat treatment for sterilization.

An alternative whole-leaf extraction method involves the same cold process leaf processing described in the first step above, but then utilizes short duration low temperature-controlled sterilization techniques to kill off bacteria, eliminating the need for additional chemicals. The resulting gel is concentrated in a vacuum chamber and dehydrated to yield a water-soluble compound that retains the biochemical activity indefinitely without using preservatives. This is currently regarded as the most efficient method. Although heat is used in the process, it is closely controlled and never reaches more than 65°C applied for less than 15 minutes at a time. Longer exposure and higher temperatures would deteriorate the final product.

It is easy to see that what you get at the store is not the same as the natural product straight from the plant. It is important to read the label and evaluate the extraction method to determine its quality. There are huge differences between manufacturers.

A self-regulating body of producers certifies Aloe Vera products according to industry standards of quality control. Their seal of approval is meant to reassure consumers. However, due to the different processing methods, certification is not a gold standard.

Gel: immune system stimulant, skin healing, anti-irritant, moisturizing, anti-cancer
Indications

Traditionally, Aloe Vera gel is used as a soothing topical application for sunburns and minor burns, abrasions, acne, psoriasis, shingles and even cold sores. The fresh gel squeezed from the leaf and applied directly to the affected areas is most potent. Its skin repair qualities on burns and sunburns are truly remarkable – healing occurs quickly and without scarring. The gel is also used to reduce stretch marks and scarring in wound care. It even protects the skin against the immune suppressant effect of ultraviolet light – thus it can also be used as a protective sunscreen lotion. Aloe Vera gel is a highly valued additive for moisturizing cosmetic preparations and is praised for rejuvenating the skin by stimulating the synthesis of elastin and collagen.

External application of Aloe gel penetrates the skin directly and produces a soothing, pain-relieving anti-inflammatory effect on arthritic joints and tendonitis.

For internal use, Aloe Vera latex preparations are usually mixed with antispasmodic herbs to reduce the cramping effect of its laxative action. Used by itself, the cathartic action could be rather painful. The latex also stimulates the uterus, thus promoting menstrual flow. Aloe containing laxatives should be avoided during pregnancy.

Laboratory studies on mice have demonstrated high-quality Aloe Vera juice to be an effective immune system stimulant in the treatment of certain types of cancer and HIV. Further studies are underway.

Aloe juice has a healing and balancing effect on the digestive system: it improves the absorption of nutrients and the elimination of toxins. This promotes overall cell nutrition and activates the body’s self-healing powers and enhances energy levels. It can also relieve gastrointestinal problems associated with peptic or duodenal ulcers. It stimulates regular bowel evacuation and soothes colitis and irritable bowel syndrome. Many chronic conditions have a component of digestive imbalance that trigger secondary symptoms due to malabsorption and cellular malnutrition. Aloe Vera juice can help to restore balance to the entire digestive system.

Aloe Vera juice also appears to benefit the liver and kidneys. It lowers levels of blood lipids (cholesterol) that can clog up the arteries and can cause coronary heart disease. And, it also has a positive effect on blood sugar levels, which can make it a useful nutritional supplement for diabetics.

Aloe vera skin care

Home-made cosmetics

If you wish to incorporate Aloe’s healing benefits into home-made skincare products, you can use the gel to replace all or a portion of the liquid in your recipe. However, beware that unprocessed Aloe Vera gel is not very stable and won’t keep long. Make small batches only, and store them in the fridge for a few days. For maximum benefit, skincare preparations should contain at least 20-40% of gel. If you have a fresh plant at your access, you can simply cut off a bit of a leaf and apply it straight to the skin.

 

Grow your own

Aloe Vera is one of those plants that everybody should have at their access as an immediate first aid remedy for burns and minor cuts. Growing it is easy, as it is a very undemanding plant. Just don’t over-water it and protect it against freezing temperatures. It loves the sun but will also grow in the semi-shade, nor does it need particularly rich soil. Well draining, sandy soil will do.

 

Caution:

  • Do not use Aloe Vera based laxatives during pregnancy. The juice may also contain traces of aloin above what would be deemed safe during pregnancy.
  • Consult with your health advisor regarding possible interference with prescription drugs if you intend to use Aloe Vera internally.
  • Rare cases of allergic reactions to the latex have been reported – even for external use.

The quality of Aloe Vera gel or juice very much depends on the manufacturing process. Some products that are currently on the market have little or no medicinal value. Do your research before spending a lot of money on what may turn out to be an inert substance. Whole-leaf extracts are recommended. Look for the International Aloe Science Council certificate for quality assurance.
