Turnera diffusa

Botanical Name :Turnera diffusa
Family: Passifloraceae
Genus: Turnera
Species: T. diffusa
Kingdom: Plantae
Order: Malpighiales

Synonym:Turnera diffusa aphrodisiaca

Common Name:Damiana

Habitat :Turnera diffusa is native to southwestern Texas in the United States,  Central America, Mexico, South America, and the Caribbean

Description:
Turnera diffusa is a relatively small shrub that produces small, aromatic flowers. It blossoms in early to late summer and is followed by fruits that taste similar to figs. The shrub is said to have a strong spice-like odor somewhat like chamomile, due to the essential oils present in the plant. The leaves have traditionally been made into a tea and an incense which was used by native people of Central and South America for its relaxing effects. Spanish missionaries first recorded that the Mexican Indians drank Damiana tea mixed with sugar for use as an aphrodisiac

Cultivation:   
Requires a dry soil in a warm sunny sheltered position. One report says that this species is hardy to about -5°c, though this needs to be treated with some caution considering its native range is entirely tropical. It is possible that, whilst the plant will be cut back to the ground by cold weather, the rootstock is hardier and will re-sprout in the spring. It will certainly be worthwhile trying the plant outdoors and giving the roots a thick protective mulch in the autumn.

Propagation:  
Seed – sow spring in a greenhouse. Prick out the seedlings into individual pots once they are large enough to handle and grow them on in the greenhouse for at least their first winter. Plant them out into their permanent positions in early summer and give some protection from winter cold for at least their first winter outdoors. Division in spring or autumn. Cuttings of half-ripe wood, July/August in a frame. Overwinter the young plants in a greenhouse and plant them out in early summer.

Constituents:  leaves: greenish volatile oil consisting of cineole, p-cymene, alpha- and beta-pinene, thymol, alpha-copaene, and calamene. the dry matter of the leaf includes damianin as well as tannins, flavonoids, beta-sitosterol, and the glycosides gonzalitosin, arbu

Medicinal Uses: * Aphrodisiac * Libido * Prostate
Properties: * Aphrodisiac * Astringent * Bitter * Nervine * Stimulant * Tonic
Parts Used: Leaf

Turnera diffusa has long been claimed to have a stimulating effect on libido, and its use as an aphrodisiac has continued into modern times. More recently, some corroborating scientific evidence in support of its long history of use has emerged. Several animal testing studies have shown evidence of increased sexual activity in rats of both sexes. Damiana has been shown to be particularly stimulating for sexually exhausted or impotent male rats as well as generally increased sexual activity in rats of both sexes. It has also been shown that damiana may function as an aromatase inhibitor, which has been suggested as a possible method of action for its reputed effects.

Turnera diffusa might be effective as an anxiolytic.

Turnera diffusa is an ingredient in a traditional Mexican liqueur, which is sometimes used in lieu of Triple Sec in margaritas. Mexican folklore claims that it was used in the “original” margarita. The damiana margarita is popular in the Los Cabos region of Mexico.

Turnera diffusa was included in several 19th century patent medicines, such as Pemberton’s French Wine Coca. The leaves were omitted from that product’s non-alcoholic counterpart, Coca-Cola.

Turnera diffusa is used primarily as an aphrodisiac for both sexes 1, and as a stimulant that can boost mental focus and stamina.

The health benefits of damiana are for the most part only verified by folklore and long observation, not by scientific study, however chemical analysis shows that damiana contains alkaloids similar to caffeine that have stimulating and aphrodisiac effects, stimulating blood flow to the genital area and increasing sensitivity. Some people report feelings of mild euphoria. Damiana is often combined with saw palmetto in formulas that address male prostate health.

Known Hazards :  Tetanus-like rigidity and genitourinary irritation in one patient. Possible hallucinations. May affect the control of blood sugar in diabetic patients

White Wines ‘Bad for the Teeth’

Enjoying a glass of white wine on a frequent basis can damage the teeth, something many wine makers and tasters will know first-hand, experts say.
……………....CLICK & SEE
Pale plonk packs an acidic punch that erodes enamel far more than red wine, Nutrition Research reports.

It is not the wine’s vintage, origin or alcohol that are key but its pH and duration of contact with the teeth.

Eating cheese at the same time could counter the effects, because it is rich in calcium, the German authors say.

It is the calcium in teeth that the wine attacks.

In the lab, adult teeth soaked in white wine for a day had a loss of both calcium and another mineral called phosphorus to depths of up to 60 micrometers in the enamel surface, which the researchers say is significant.

Riesling wines tended to have the greatest impact, having the lowest pH.

A “kinder” tooth choice would be a rich red like a Rioja or a Pinot noir, the Johannes Gutenberg University team found.

Power of saliva
Even if people brush their teeth after a night of drinking, over the years repeated exposure could take its toll, say Brita Willershausen and her colleagues.

Indeed, excessive brushing might make matters worse and lead to further loss of enamel.

But they said: “The tradition of enjoying different cheeses for dessert, or in combination with drinking wine, might have a beneficial effect on preventing dental erosion since cheeses contain calcium in a high concentration.”

This helps neutralise and boost the remineralising power of saliva to halt the acid attack.

But eating strawberries while supping on your vino or mixing sparkling whites with acid fruit juice to make a bucks fizz may spell trouble because this only adds to the acid attack.

Professor Damien Walmsley, of the British Dental Association, said: “The ability of acidic foods and drinks to erode tooth enamel is well understood, and white wine is recognised as being more erosive than red.

“But it’s the way you consume it that’s all important. If you’re going to have a glass of wine do so with your meal and leave a break of at least 30 minutes afterwards before you brush your teeth and go to bed.

“Consuming wine alongside food, rather than on its own, means the saliva you produce as you chew helps to neutralise its acidity and limits its erosive potential.

“If you’re going to have a glass of wine do so with your meal and leave a break of at least 30 minutes afterwards before you brush your teeth and go to bed.”….Says Professor Damien Walmsley of the British Dental Association

“And leaving time before brushing teeth gives the enamel a chance to recover from the acid attack and makes it less susceptible to being brushed away.”
