Turnera diffusa






Damiana is a small shrub with small, fragrant flowers that blossoms in early to late summer. The strong spice-like odour, a little like chamomile, is due to the plant's essential oils. Damiana is widely sold in the UK as a food supplement with much of its popularity being due to its traditional use in enhancing low libido in both men and women.

Food Use

The leaves are traditionally made into a delicious tasting tea for its relaxing effects. The fruits of damiana taste similar to figs.

Records from Spanish missionaries suggest that Mexican Indians considered that Damiana tea mixed with sugar was an aphrodisiac food.

Damiana extract is an ingredient in a traditional Mexican liqueur. It is used in the "original" margarita from the Los Cabos region of Mexico called a "damiana margarita". It is sometimes used in lieu of Triple Sec when making margaritas. The tincture can be also be added as a flavouring to gin or vodka.


Use 1 teaspoon of dried herb (2 g) to one cup of boiling water to make a tasty tea. Infuse for 10-15 minutes. Sweeten with honey to taste.

Alternatively add half a teaspoon (3 ml) of tincture to a cup of warm water for a quick alternative to tea. Or mix with soda water and lemon as a refreshing drink.


Honeymoon Tea

Combine 7 parts of damiana with 2 parts of rose petals and 1 part of ginger root powder by weight. Mix well and use as a herbal tea allowing 1 to 2 teaspoons per person. Infuse in hot water for 10 minutes and drink several times a day for several days prior to the honeymoon.

Smoking: Inhaling smoke into your lungs is bad for your health. Although damiana does not contain nicotine and has been smoked by some people to relieve the anxiety associated with giving up smoking, we do not recommend smoking dried damiana leaf herb.

It has in the past been mixed with cannabinoids in blends such as Black Mamba to create legal highs. Black Mamba is illegal in the UK and all smoking is harmful to your health.
