including Mexico and parts of Texas, the Caribbean, and
southern Africa.

Historical
or traditional use (may or may not
be supported by scientific
studies)
Damiana has been hailed as an aphrodisiac
since ancient times, particularly by the native peoples
of Mexico. Other folk uses have included asthma,
bronchitis, neurosis, and various sexual disorders. It
has also been promoted as a euphoria-inducing
substance.
Active constituents
Most
research has been done on the volatile oil of damiana,
which includes numerous small, fragrant substances
called terpenes. As yet, it is unclear if the volatile
oil is truly the main active constituent of damiana.
Damiana extracts have been shown, in a test tube, to
weakly bind to progesterone receptors. Thus, damiana may
be a potentially useful herb for some female health
problems. However, no human studies have investigated
this possibility and it is not a primary traditional
use.
How much is usually
taken?
To
make a tea, add 1 cup (250 ml) boiling water to 1/4
teaspoon (1 gram) of dried leaves and allow to steep for
ten to fifteen minutes. People can drink three cups (750
ml) per day. To use in tincture form, take 1/2–3/4
teaspoon (2–3 ml) three times daily. Tablets or capsules
(400–800 mg three times per day) may also be used.
Damiana is commonly used in herbal combinations.
However, the authors of the German Commission E
monographs do not feel that traditional use of this herb
is justified by modern
research.
Are there any side effects or
interactions?
The
leaves have a minor laxative effect and may cause
loosening of the stools at higher amounts. Until more is
known about damiana’s effects on the female hormonal
system, it should be avoided during
pregnancy. |
