 Damiana is a yellow-flowering plant that is frequently
found growing in climates that are relatively hot and humid
including Central and South America and the in a few states in the
United States. Damiana was traditionally used as a respiratory,
neurological, and sexual medicine by indigenous cultures of Mexico.
Commercially introduced in the United States in 1874, damiana has
historically been used as an aphrodisiac and has been claimed to
induce euphoria, as well as to help people with
depression.
Although there is a clear lack of scientific
evidence to support any of the theories for the efficacy attributed
to damiana, its seeming ability to induce mild euphoria could
support a logical theory that in relatively small quantities,
damiana could lead to relaxation and could calm anxiety.
Conceivably, those suffering from sexual dysfunction resulting from
stress or emotional troubles could benefit from supplementation with
this herb. But again, there is not enough scientific evidence to
support its use as a medicinal herb.
Dosage and
Administration
While damiana is commonly used in
herbal combinations most experts do not feel that traditional use of
this herb is justified by modern research.
Possible
Side Effects and 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.
