Studies indicate possible antibacterial qualities, as well as the ability to lower blood sugar.    (61)

A sexual rejuvenator;  has a tendency to overstimulate if used excessively.  Mildly stimulates urine flow.  A tonic to the nervous system in small, frequent doses.  (14)

Traditionally used as a tea that can also treat colic, bed wetting, and amenorrhea.  Inhaling the steam from the tea is aid to relieve headache.  Its reputation as an aphrodisiac comes from attempts to market the herb in the 1870’s.  Nearly a century later, the controversy continues.  Nearly all modern herb books mention its use as an aphrodisiac.  As professor John Lloyd pointed out in 1904, this resulted from use of the name “damiana” on patent medicine preparations promoted as aphrodisiacs, whose other ingredients were not revealed.  No reasonable scientific evidence confirms damiana’s reputation as an aphrodisiac.    (61)

Combinations: Often used with oats as a nerve tonic;  combines well with Kola or Skullcap.  (8)

combine w/ oats for general depression;  for anxiety, combine w/ skullcap or wood betony, equal amounts of tinctures, up to 5 ml per dose;  combine w/ Buchu to warm the kidneys.  (15)

Combines well with serona repens (saw palmetto–see pg. 352 of reference) as a tonic for sexual neurosis; with avena sativa (oats–see pg. 246) for depression, and with scutellaria lateriflora (scullcap–see pg. 351) or  stachys officinalis (wood betony–see pg. 355) for anxiety states.  (38)

Precautions:  No known hazards or side effects if administered within designated dosages.  (2)

Given damiana’s long history in Mexico, predating the Spanish invasion, safety seems established.  However, lacking toxicological studies, it should be used in moderation.    (61)
