Aloe vera: Nature's best kept
secret Aloe vera
by Dr. Caroline Shreeve
Aloe vera is a plant of many surprises. It
looks like a cactus, grows in dry surroundings, but belongs to the lily family.
It stays moist and cool where other plants wilt, shutting down its pores to
prevent water loss. When cut or damaged, its healing powers come to light,
forming a protective covering, to ensure that the plant continues to thrive. It
grows naturally in Africa, America, Europe and Asia where there are over 200
varieties of the plant, but it is the Aloe barbadensis (Aloe vera) variety
which has the best medicinal properties.
Aloe vera – history and legend
Most importantly, Aloe vera has a long
history as a safe, effective medicine and skin care aid. For over 6,000 years,
people have benefited from the remarkable relief that the plant can bring to a
wide range of ailments. The ancient Egyptians used Aloe to heal battle wounds
and cure infections. Writings of the early Greeks show how they valued it for
relieving blisters, burns and leg ulcers as well as bowel and stomach
disorders.
Legend has it that Aristotle persuaded
Alexander the Great to conquer the Isle of Socroto, to secure enough Aloe vera
to heal his soldiers’ wounds. Cleopatra relied on it for her unlined, youthful
complexion, whilst the Chinese hailed Aloe as an elixir of youth. Aloe is also
listed in St. John’s gospel as an anointing ingredient for the body of Christ.
Aloe vera rediscovered
Doctors rediscovered Aloe vera in the 1930s,
when it was found to heal radiation burns due to X-rays, where other methods
had met with little success. It did the same for atomic fallout victims a
decade later, following the Nagasaki and Hiroshima bombings.
The plant’s clear, glassy leaf sap is used
today to relieve ailments from insect bites, stings and sunburn to peptic
ulcers, diarrhoea and stiff, painful joints.
Aloe vera’s healing actions
Traditional remedies are often founded on
firm scientific fact. Studies have confirmed Aloe vera as a rich source of
healing ingredients which work synergistically, enhancing one another’s
effects. These ingredients include vitamins, minerals, proteins, enzymes and
amino acids.
Aloe vera extract acts in three main ways:
* as an anti-inflammatory
agent
* a wound healer
* an antioxidant
one or all of which may contribute to
relieving a particular ailment.
Aloe vera is anti-inflammatory
Inflammation is our body’s natural way of
responding to infection, toxins or injury. It is characterised by redness,
swelling and heat caused by an increase of blood to the damaged area.
Sometimes, however, inflammation can backfire or get out of hand. Arthritis is
a debilitating and painful condition which can be caused by antibodies produced
against the body’s own tissues, resulting in sore, inflamed joints and loss of
movement.
Steroids (e.g. hydrocortisone) suppress
inflammation but can cause weight gain, brittle bones and thin, weak skin.
Non-steroidal anti-inflammatory drugs (e.g. aspirin and ibuprofen) ease swollen
joints and improve mobility but may trigger stomach upsets or peptic ulcers.
Plant steroids in Aloe vera can relieve
inflammation, help to regenerate new cells and disperse damaged tissue with no
side-effects.
Besides arthritis and rheumatism, these
natural plant steroids also work well for sunburn, insect bites and stings,
rashes, mouth ulcers, inflamed stomach and bowel disorders.
Three other common conditions which benefit
from Aloe vera’s anti-inflammatory action are heartburn, peptic ulcers and
piles. Heartburn happens when the foodpipe or gullet gets inflamed by stomach
acid. Peptic ulcers erode the lining of the stomach or small bowel (duodenum),
causing inflammation and pain. Piles, which are inflamed varicose veins at the
exit of the bowel or anus, can also smart, sting and bleed.
Aloe vera as a wound healer
Soapy substances in Aloe vera gel (saponins) cleanse wounds
of dirt and debris, treat oil-clogged pores and help kill any microbes present.
The woody, pulpy microfibres in Aloe vera’s sap (lignins) soften hard skin and
gently penetrate the tissues. Other active ingredients and oxygen can then
reach down into the depths of the wound.
The anthraquinones in Aloe vera loosen
debris, pus and dead cells, bring blood to the area and flush out matter from
wounds and ulcers. They also kill bacteria, some viruses and fungi. A
biological growth stimulator present in Aloe vera helps to regenerate new
tissue, guard against sepsis and promote the healing in cuts and wounds.
Studies have shown that the growth
stimulator attaches itself to tissue cells called fibroblasts. These produce
long thin strings of collagen and elastin, adding strength and bringing the
edges of the wound together.
Typical ailments to benefit from these
actions include mouth and peptic ulcers, and the large ulcer craters often
found on the legs of elderly people with diabetes or poor circulation. The
antiseptic actions of saponins and anthraquinones also help peptic ulcers (now
known to be partly due to bacteria); and acne in which infection with skin
bacteria plays an important part.
One of Aloe vera’s most popular uses is in
the treatment of minor burns which benefit from new skin regeneration without
unsightly scarring. Eczema and psoriasis also benefit from the ability of
lignins to penetrate the toughened skin surface.
Aloe vera as an antioxidant
Antioxidants are essential for a healthy
metabolism and to protect against free radicals. These form when a molecule
loses an electron as a result of the normal metabolism which occurs as food and
oxygen are turned into energy. Large numbers of these highly-charged molecular
fragments can weaken the immune system which fights infection and resists
degenerative changes.
Triggers include growing older, viral
infections, high intakes of animal fat and or alcohol, stress, smoking,
pollution and other toxins. Effects include ageing, wrinkled skin and an
increased risk of arthritis, cancer and infections.
Aloe vera contains naturally occurring
antioxidants in the form of vitamins B complex, C and E, plus beta-carotene
which is converted by the body into vitamin A. Dietary nutrients in Aloe vera
also include potassium, calcium, magnesium, zinc, manganese, chromium and
sodium and all are essential for maintaining a healthy metabolism.
Aloe vera – the choice
The extract from the leaves of the Aloe vera
plant can be found in many health and beauty products. Aloe vera juice can be
produced from either liquid or powdered Aloe, but it is only recommended and
advisable to buy juice made from the liquid extract. Also ensure the Aloe
content is a minimum of 95% by volume. This is not to be confused with the
purity of Aloe vera which is often shown as 100%. A flavoured juice is
considered by many to be more palatable but natural juices are more suitable
for those with fruit allergies or who suffer from candida. A regular small dose
is recommended and the effectiveness can vary, some experiencing benefits
immediately, whereas others can take several weeks.
Aloe vera gel is primarily used externally
for skin conditions such as acne, sunburn, psoriasis, cuts, bruises and stings.
The pure gel is clear, non-sticky, odourless, easily absorbed and can be used
as often as required.
Medical Advice
Consult your doctor for disorders that do
not improve or which you suspect might be serious. Irritable bowel syndrome
(with wind, pain and constipation or diarrhoea), peptic ulcers, diverticulitis
(a type of large bowel inflammation) for instance, need to be diagnosed and
require conventional treatment. Aloe vera, which is safe and without side
effects, can work well with other medicines, bringing additional relief and
hastening healing.
