(infusion Turnera diffusa)
from AMAZON HERBS®
Damiana is a small tropical shrub, indigenous to Suriname. The leaves are used for medicinal purposes.
In traditional medicine, Damiana is used as an aphrodisiac (increases sexual desire and enhances performance). However there are also other applications such as antidepressant, nerve tonic (mild depression and anxiety), diuretic, cough-suppressant, kidney, menstrual, pregnancy disorders and mild laxative.
The leaf infusion has been used as a traditional remedy in diseases related to the gastrointestinal and respiratory systems, reproductive organs, Parkinson's disease, PMS, inflammation of the prostate and for the treatment of gonorrhea in Latin American societies.
Damiana is approved for food use by the United States Food and Drug Administration (FDA).
Flavonoids (Gonzalitosin I), Cyanoglycoside (Tetraphyllin B), Volatile Oils (alpha-pinene, beta-pinene, p-cymene, 1, 8-cineole) Phytosterol (beta-sitostero), beta carotene, Hydrocarbons (triclosan-2-one hexacosanol) Phenolic Glycoside (Arbutin) Damianin, pinocembrin, acacetin, tannins.
Research suggests that Damiana relieves anxiety, depression and headaches during menstruation and exhaustion. It also helps to balance female hormone levels and control hot flashes.
A clinical study reported that components in Damiana bound to progesterone receptors in human breast cancer cells, leading researchers to surmise that it had a neutral or anti-estrogenic activity.
According to one study, Damiana was reported as one of the top six highest progesterone-receptor binding herbs commonly consumed.
New research on the ability of Turneraceae to prevent ulceration of the gastric and duodenal mucosa, suggests that the flavonoids present in Damiana have a significant anti-ulcerogenic effect.
This can lead to Turneraceae as a new source of anti-ulcerogenic drugs*.
The hypoglycemic activity of water-ethanol extract prepared from Turnera diffusa was investigated but did not show any hypoglycemic activity.
Anti-inflammatory studies were conducted using a crude hydroalcoholic extract of the aerial parts of Turnera and its partitioned fractions, i.e. the aqueous, ethyl acetate and ethanolic fractions.
The anti-ulcerogenic effect of the extract and of the ethanolic fraction may be related to an increase of mucosal defensive factors, such as prostaglandin and mucus.
The anti-inflammatory actions of the extract and the fraction may be due to an inhibitory effect on histamine and cyclooxygenase II. The major substances present in the ethanolic fraction are flavonoids.
Due to the phytochemical Arbutin, Damiana can be helpful in cases of urinary infections, such as cystitis (arbutin in converted to hydroquinone, a compound with astringent properties that works on the urinary tract.
A recent research reported that the active ingredients pinocembrin and acacetin are potent inhibitors of the aromatase enzyme. Aromatase converts testosterone into estrogen, so the testosterone levels are kept higher.
Tincture: 1 - 5 ml daily, to regulate female cycles of the reproductive system and hot flashes.
Infusion (herbal tea): 2 - 3 cups daily.
When used as such, it has a relaxing effect similar to low doses of cannabis.
As a sexual stimulant, 5 ml of the tincture 30 - 45 minutes before sex.
It can be used by both men and women.
As a nerve tonic; 4 ml. 2 times daily.
Damiana tea is fragrant with a delicious aroma and a light, agreeable bitter taste.
Do not use during pregnancy since it is used as an abortive in traditional medicine.
Since it is a nervous system stimulant, epileptics should take care in using it.
*Antiulcer drugs are a class of drugs exclusive of the antibacterial agents, used to treat ulcers in the stomach and the upper part of the small intestine.
