Damiana Leaf – Turnera diffusa (Da Mia Na)
Country of origin: Mexico
A shrub native to southern Texas in the United States, Central America, Mexico, South America, and the Caribbean. It belongs to the family Passifloraceae. Damiana is a relatively small, woody 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.
Damiana is an ingredient in a traditional Mexican liqueur, which is sometimes used in lieu of triple sec in margaritas.It has been in use since the times of the ancient Aztec and is still quite popular today. Although its effect as an aphrodisiac was its primary use across cultures, it was also valued as a nerve relaxant, digestive stimulant, mood enhancer, and simply an enjoyable beverage that was even given to children. Mexican folklore claims that it was used in the “original” margarita. The damiana margarita is popular in the Los Cabos region of Mexico. Damiana 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.
Damiana contains damianin; tetraphyllin B; gonzalitosin I; arbutin; tricosan-2-one; acacetin; p-cymene; β-sitosterol; 1,8-cineole; apigenin; α-pinene; β-carotene; β-pinene; tannins;thymol; and hexacosanol. In total, 22 flavonoids, maltol glucoside, phenolics, seven cyanogenic glycosides, monoterpenoids, sesquiterpenoids, triterpenoids, the polyterpene ficaprenol-11, fatty acids, and caffeine have been found in the genus Turnera. As of 2006, damiana’s constituents have not been identified for their effects attributed to the whole herb. Damiana’s anxiolytic properties might be due to apigenin.
