Turnera diffusa

Turnera diffusa, known as damiana,[3] is a shrub native to southern Texas in the United States,[4] Central America, Mexico, South America, and the Caribbean. It belongs to the family Passifloraceae.[2]

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.[5]

Uses

Damiana 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.[6][7]

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.[8]

Phytochemistry

Damiana contains damianin; tetraphyllin B; gonzalitosin I; arbutin; tricosan-2-one; acacetin; p-cymene; β-sitosterol; 1,8-cineole; apigenin;[9] α-pinene; β-carotene; β-pinene; tannins; thymol;[10] and hexacosanol.[11] 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.[12]

As of 2006, damiana's constituents have not been identified for their effects attributed to the whole herb.[13] Damiana's anxiolytic properties might be due to apigenin.[11]

The extract from damiana has been found to suppress aromatase activity, including the isolated compounds pinocembrin and acacetin.[14][15]

Ecology

T. diffusa is a host plant for the Mexican Fritillary (Euptoieta hegesia).[16]

Misidentification in commerce

Viable plant and seed material sold as T. diffusa from both private and commercial sources largely turns out to be misidentified Turnera ulmifolia (a.k.a. "False Damiana"), a closely related species. This widespread issue has been noted by the scientific community, and has created much confusion among both amateur and professional horticulturists alike.[17][18][19] While T. ulmifolia is similar in appearance, its chemical constituents and ethnobotanical uses are distinctly different.[20] Mature stems of T. diffusa are woody, with small, grayed green leaves 13 to 16 mm long, 4.5 to 5.5 mm wide, obtuse at the apex, and strongly aromatic when crushed.[21] T. ulmifolia is differentiated by herbaceous stems, larger blue-green leaves that are strongly dentate with a pointed apex, and only weakly aromatic.[22][23][24]

One scientific study however, demonstrated this confusion being mostly associated with horticultural commerce, and does not extend appreciably to commercial herbal products, most of which exhibit constituents that can be definitively traced to T. diffusa.[25]

Acacetin

Acacetin is an O-methylated flavone found in Robinia pseudoacacia (black locust), Turnera diffusa (damiana), Betula pendula (silver birch), and in the fern Asplenium normale.The enzyme apigenin 4'-O-methyltransferase uses S-adenosyl methionine and 5,7,4'-trihydroxyflavone (apigenin) to produce S-adenosylhomocysteine and 4'-methoxy-5,7-dihydroxyflavone (acacetin).

Aromatase inhibitor

Aromatase inhibitors (AIs) are a class of drugs used in the treatment of breast cancer in postmenopausal women and gynecomastia in men. They may also be used off-label to reduce estrogen conversion when using external testosterone. They may also be used for chemoprevention in high risk women.

Aromatase is the enzyme that catalyzes a key aromatization step in the synthesis of estrogen. It converts the enone ring of androgen precursors such as testosterone, to a phenol, completing the synthesis of estrogen. As breast and ovarian cancers require estrogen to grow, AIs are taken to either block the production of estrogen or block the action of estrogen on receptors.

Eucalyptol

Eucalyptol is a natural organic compound that is a colorless liquid. It is a cyclic ether and a monoterpenoid.

Eucalyptol is also known by a variety of synonyms: 1,8-cineol, 1,8-cineole, cajeputol, 1,8-epoxy-p-menthane, 1,8-oxido-p-menthane, eucalyptol, eucalyptole, 1,3,3-trimethyl-2-oxabicyclo[2.2.2]octane, cineol, and cineole.

In 1870, F. S. Cloez identified and ascribed the name "eucalyptol" to the dominant portion of Eucalyptus globulus oil.

Euptoieta hegesia

Euptoieta hegesia, the Mexican fritillary, is a North and South American butterfly in the family Nymphalidae.

Gifiti

Gifiti (also guifiti, giffidy, geffidee) is a rum-based bitters, made by soaking roots and herbs in rum. It is traditionally made by the Garifuna people of the Caribbean coast. Gifiti is traditionally used medicinally, with different compositions for men and women, but is also consumed recreationally, most commonly as shots. Color depends on composition; it is often green or brown.

List of phytochemicals in food

While there is ample evidence to indicate the health benefits of diets rich in fruits, vegetables, legumes, whole grains and nuts, no specific food has been acknowledged by scientists and government regulatory authorities as providing a health benefit. Current medical research is focused on whether health effects could be due to specific essential nutrients or to phytochemicals which are not defined as essential.The following is a list of phytochemicals present in commonly consumed foods.

Mina, Nuevo León

Mina is town and municipality located in the Northwestern part of the northeastern Mexican state of Nuevo León. The population was 4,309 at the 2005 census. Its name honors Spaniard insurgent general Francisco Javier Mina, who fought for the Mexican side in the independence movement from Spain. Located at the northwestern part of the state of Nuevo León. Mina is a renowned tourist destination, for its mysticism and legends in the state of Nuevo León.

Pinocembrin

Pinocembrin is a flavanone, a type of flavonoid. It is an antioxidant found in damiana, honey, fingerroot, and propolis.Pinocembrin can be converted biosynthetically to pinobanksin by hydroxylation adjacent to the ketone. Studies have shown that pinocembrin has potential as a drug to treat cerebral ischemia, intracerebral hemorrhage, neurodegenerative diseases, cardiovascular diseases and atherosclerosis as well as other diseases.

Turnera

Turnera is a genus of flowering plants in the passionflower family, Passifloraceae. It contains more than 100 species native to tropical and subtropical America. The name honours English naturalist William Turner (1508-1568). It was previously placed in the family Turneraceae.

Turnera ulmifolia

Turnera ulmifolia, the ramgoat dashalong or yellow alder, is a species of plant of family Passifloraceae, native to Mexico and the West Indies. A recent study found that yellow alder potentiated the antibiotic activity against methicillin—resistant Staphylococcus aureus (MRSA).
