The Versatile Damiana
The Maya Indians of Yucat√°n regarded Damiana as mizib-coc/mizibcoc, which means 'plant for asthma'. Besides being known for its aphrodisiac properties, damiana, for the Mayans, was used as a potent body cleanser, and served to be a remedy for pulmonary disorders, vertigo, and lightheadedness.
Damiana is a small shrub of the family Turneraceae, and is native to the regions of Mexico, Central and South America, and the West Indies. The scientific name of this plant is Turnera diffusa. The leaves of this plant are aromatic, and their smell is said to be somewhat similar to that of chamomile. They can be used to prepare herbal tea, which was once used by the native people of Central and South America, for its supposed aphrodisiac properties. Apart from making tea, this herb is also used in traditional Mexican liqueur. Its leaves are also smoked, which is said to produce a calm and euphoric effect on the body and mind.
Damiana Gains
Libido
One of its main constituents is active alkaloids, which may have a testosterone-like effect in the body. Hence, this herb is used as an aphrodisiac to stimulate and boost libido, and treat impotency in both men and women. A study carried out in potent and impotent male rats, found that, its leaf extract improved the mating behavior of sexually sluggish and impotent male rats, but no difference was seen in potent male rats. It is presumed to be helpful in treating erectile dysfunction in men.

Testosterone
A research conducted by the US Department of Agriculture (USDA), pointed that damiana leaves are likely to raise testosterone levels. A nitrogen alkaloid in this herb behaves like the male hormone testosterone. In vitro trials also point that, the extracts of this herb curb the aromatase enzyme (reason for testosterone conversion to estrogen), and causes the muscles to smoothen and relax.

Menstruation
This herbal leaf has been proved to be useful in relieving painful menstruation and other hormonal troubles, as it has a normalizing and balancing effect on the hormones. It also aids in relieving symptoms like hot flashes or night sweats. It is considered that damiana has phytohormonal compounds, which keep the hormones balanced, and fortifies the reproductive organs in women.

Blood Glucose and Anti-inflammatory Agent
In 1984, Mexican scientists documented damiana's hypoglycemic properties. Later, in the same year, a study was published in the December edition of the Journal of Ethnopharmacology, which stated that this herbal leaf might help in lowering the blood glucose levels in diabetic patients. Damiana has an antiulcerogenic effect, which increases the secretion of gastric mucus, and thereby is also known to have anti-inflammatory properties. It even acts as an astringent and detoxifies the urinary tract disease, which must have been preexistent within the genitourinary system.

Depression and Restiveness
Inadequate flow of blood may lead to lethargy and chronic exhaustion. In such a case, this herb may aid in rejuvenating vitality. Damiana is believed to have anti-depressant properties, and hence, it is considered as a tonic for the central nervous system. It is used as a central nervous system depressant to alleviate conditions like anxiety, nervousness, and depression.

Apart from these, this herb also helps to increase metabolism, relieve cough, asthma, and bronchitis. It is a natural laxative, and hence, can aid in ensuring regular bowel movements. Therefore, people suffering from constipation may find this herb quite beneficial.
