Triphala
by Jim English
Ayurveda is a 5,000 year-old healing tradition
rooted in ancient Indian culture. This vast body of healing knowledge
— sometimes referred to as the "Mother of All Healing"
— has recently come to the attention of Western medical researchers
seeking novel therapeutic compounds. While screening a number of
traditional Vedic formulas scientists discovered that one of the
most revered of all Ayurvedic compounds — Triphala —
exhibits a number of health benefits, including:
- Exhibits antioxidant activity
- Lowers cholesterol
- Normalizes blood pressure
- Inhibits HIV
- Reduces tumors in animals, and
- Protects and improves liver function
Triphala is a botanical preparation comprised of equal parts of
three herbal fruits: Harada (Terminalia chebula, black
myrobalan, The Buddha’s Chosen Herb), amla (Emblica officinalis
or Indian gooseberry), and bihara (Terminalia bellerica).
Harada (Terminalia chebula)
According to the renowned herbalist, Dr. Michael Tierra, Tibetans
so revere Harada (Terminalia chebula) that the fruit
is depicted in the hand of the "Medicine Buddha" in
sacred paintings.(1) Numerous studies have found that Terminalia
chebula (TC) supports digestion and aids in treating both
acute and chronic constipation.
Amla (Emblica officinalis)
Amla (Emblica officinalis) is the edible fruit from a
small tree native to India. As with Terminalia chebula,
EO has been shown to increase gastric emptying and to possess
a broad spectrum of antimicrobial activity against a number of
test bacteria.(2)
Bihara
Bihara fruit (Terminalia bellerica) is rich in protein
(40 percent) and oils (35 percent), and is particularly high in
the omega 3 essential fatty acid, linoleic acid.
Healthy digestion requires the coordination of a complex pattern
of contracting and relaxing muscles in the stomach and intestines
(gastric motility) for proper digestion and absorption of nutrients.
Gastrointestinal motility is disrupted when the nerves and muscles
of the GI tract fail to function in a strong or coordinated fashion.
Motility can be disrupted by stress, inflammation (i.e. Crohn’s
disease), disease (i.e. muscular dystrophy, systemic sclerosis and
amyloidosis) and from use of over-the-counter and prescription medications.
Symptoms of motility disorder range from mild
cases of heartburn and constipation to more severe problems, such
as chronic vomiting, nausea, cramping, bloating, abdominal distention
and diarrhea after eating. The most prevalent form of motility disturbance
is Irritable Bowel Syndrome (IBS), which fully accounts for 50 percent
of all patients who go to a GI specialist.(3)
To increase GI muscle contractions and improve gastric emptying,
Western doctors often prescribe prokinetic drugs such as Metoclopramide
or Bethanechol. When researchers compared the Triphala herb Harada
(Terminalia chebula) to prokinetic drugs they found that Terminalia
chebula increased gastric emptying by 86 percent, compared to 76
percent for metoclopramide. Since Terminalia is free of side effects,
the herb may be a useful alternative to the prokinetic drugs currently
available.(4)
Recently published studies report that Terminalia exhibits antibacterial
activity against a number of bacterial species.(5) One group of
researchers found that Terminalia is effective in inhibiting the
urease activity of Helicobacter pylori (H. pylori), a ubiquitous
bacterium implicated in the development of gastritis, ulcers and
stomach cancers.(6)
Another research team has shown that extracts
of Terminalia chebula strongly inhibit the growth and adherence
of Streptococcus (S. mutans), a virulent cavity-inducing organism.
Oral rinsing with an extract of Terminalia chebula was found to
significantly reduce both total bacterial counts and streptococcal
counts in saliva samples. The protective effect lasted for up to
3 hours after rinsing, demonstrating a potential role for TC in
the prevention of dental caries.(7)
Terminalia has been found to possess antiviral activity. Researchers
have reported that Terminalia protects epithelial cells against
influenza A virus, supporting the traditional use of Terminalia
for aiding in recovery from acute respiratory infections.(8) Terminalia
has also demonstrated therapeutic activity against herpes simplex
virus (HSV) in in vivo tests.(9) These findings prompted
a team of Japanese researchers to investigate Terminalia’s
effects on human cytomegalovirus (CMV). They found that Terminalia
was effective in inhibiting the replication of human cytomegalovirus
(CMV) in vitro and in immunosuppressed mice. Stating that "Terminalia
chebula significantly suppressed MCMV (murine CMV) yields in lungs
of treated mice," the researchers concluded that Terminalia
may be beneficial for the prevention of CMV diseases in immunocompromised
patients.(10)
Animal studies show that when extracts of Terminalia were administered
following induction of anaphylactic shock, serum histamine levels
were reduced, indicating that Terminalia may possess a strong anti-anaphylactic
action.(11) Indian researchers have also shown that Amla (Emblica
officinalis) protected experimental animals when exposed to a variety
of biological, physical and chemical stressors. Oral Emblica was
shown to normalize phagocytic activity, fitting within the definition
of an adaptogen. Emblica was also found to protect tissues from
stress-induced free radical damage, with a strong affinity for cells
involved in prostaglandin synthesis.(12)
Because Emblica officinalis fruit (commonly known as amla) is the
world’s richest source of natural vitamin C, researchers have
attributed many of its traditional benefits to its antioxidant properties.(13)
In one study amla was found to be more effective than vitamin C
in improving lipoprotein values and glucose tolerance. Volunteers
given amla were compared to controls receiving 500 mg/day of vitamin
C. After 8 weeks the amla group showed significant improvements
in lipoprotein serum profiles, including increased HDL, decreased
LDL, and lower total cholesterol levels.(14)
In addition to vitamin C, researchers at the Bose
Institute in Calcutta, India have also isolated a number of tannins
in amla that exhibit potent antioxidant activity. The antioxidant
effects of amla were measured on the basis of their effects on rat
brain concentrations of the oxidative free radical scavenging enzymes,
superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase
(GPX) and lipid peroxidation. The results were compared with effects
induced by deprenyl, a selective mono-amine oxidase (MAO) B inhibitor
with well documented antioxidant activity. Amla and deprenyl both
effectively increased SOD, CAT and GPX activity, with concomitant
decreases in lipid peroxidation when administered once daily for
seven days. These results indicate that the antioxidant activity
of amla may derive from the tannoids of the fruits of the plant,
which have vitamin C-like properties, rather than vitamin C itself.(15)
Indian researchers have shown that extracts of amla exhibit antitumor
activity. Solid tumors induced by DLA (Dalton’s lymphoma ascites)
cells were reduced significantly when mice were fed either amla
or an herbal preparation containing 50% amla. Amla extract was also
shown to increase the life span of tumor bearing animals by up to
60%. The researchers theorize that the antitumor activity of amla
may partially be due to its interaction with cell cycle regulation.(16)
In addition to the previously reported effects of amla on normalizing
lipid profiles, Indian scientists have reported that flavonoids
extracted from amla exert highly potent hypolipidemic and hypoglycemic
activities. Moreover these flavonoids were effective in raising
the hemoglobin levels in rats.(17)
Amla has also been shown to possess potent antiatherosclerotic
effects. Researchers evaluated the lipid lowering effects of amla
in rabbits fed a cholesterol-rich diet to induce hyperlipidemia.
Following 60 days of supplementation with amla, serum cholesterol,
triglyceride, phospholipid and LDL levels were lowered by 82%, 66%,
77% and 90%, respectively. The researchers also reported a significant
reduction in aortic plaque deposits in rabbits treated with amla,
leading researchers to conclude that amla is "an effective
hypolipidemic agent and can be used as a pharmaceutical tool in
hyperlipidemic subjects."(18)
It is important for those of us who are schooled in western medicine
to recognize that many of the ancient Chinese and Aryuvedic formulas
contain healing potentials that are often qualitatively different
from the simple sum of each individual ingredient. Triphala has
shown itself to be one such herbal combination. This herbal combination
can have profound healing benefits in complex, multi-organ systems.
Its role in preventive medicine cannot be minimized.
