The health applications for
ashwagandha in traditional Indian and Ayurvedic medicine are extensive. Of
particular note is its use against tumors, inflammation (including arthritis),
and a wide range of infectious diseases. The shoots and seeds are also
used as food and to thicken milk in India. Traditional uses of ashwagandha
among tribal peoples in Africa include fevers and inflammatory conditions.
Ashwagandha is frequently a constituent of Ayurvedic formulas, including
a relatively common one known as shilajit.
Active constituents: The
constituents believed to be active in ashwagandha have been extensively
studied. Compounds known as withanolides are believed to account for the
multiple medicinal applications of ashwagandha. These molecules are
steroidal and bear a resemblance, both in their action and appearance, to the
active constituents of Asian ginseng (Panax ginseng) known as ginsenosides.
Indeed, ashwagandha has been called Indian ginseng by some.
Ashwagandha and its withanolides have been extensively researched in a variety
of animal studies examining effects on immune function, inflammation, and even
cancer. Ashwagandha stimulates the activation of immune system cells, such as
lymphocytes. It has also been shown to inhibit inflammation and improve
memory in animal experiments. Taken together, these actions may support
the traditional reputation of ashwagandha as a tonic or adaptogen - an herb
with multiple, nonspecific actions that counteract the effects of stress and
generally promote wellness.
Some experts recommend
36 grams of the dried root, taken each day in capsule or tea form.
To prepare a tea, 3/41 1/4 teaspoons (36 grams) of ashwagandha root
are boiled for 15 minutes and cooled; 3 cups (750 ml) may be drunk daily.
Alternatively, tincture 1/23/4 teaspoon (24 ml) three times per
day, is sometimes recommended.
No significant side effects
have been reported with ashwagandha. The herb has been used safely by children
in India. Its safety during pregnancy and breastfeeding is unknown. At
the time of writing, there were no well-known drug interactions with
ashwagandha.
