I pulled this directly off of Wikipedia.
In herbal medicine, damiana is used to treat conditions ranging from coughs to constipation to
depression. The herbal supplement is reputed to help with energy, emphysema, low estrogen, frigidity, hot flashes, impotency,
infertility, menopause, Parkinson's disease, PMS, inflammation of prostate, Lou Gehrig's disease, and more dealing
with reproductive organs in both males and females. Damiana can also be made into a liquor. A traditional Mexican liquor,
it is sometimes used in margaritas. Mexican folklore claims that it was used in the first margarita.
This particular drink is popular in the Los Cabos region of Mexico. (The bottle of my favorite brand in shaped like the torso
of a voluptuous woman.) Damiana
can also be smoked in which the effects are somewhat similar to Cannabis sativa although milder and more relaxing.Damiana
has a synergistic effect with Passionflower which when smoked in a combination has been said to be extremely relaxing and promotes lucid
dreaming. It can also be brewed in a tea.
