+The tannin-rich bark is wrinkled, reddish-brown to grey, with fibrous texture, 0.5-1.5 mm thick, resinous and with an astringent odor and flavor. Preparations (bark tea, powder and/or ointment) are used against skin wounds and burns - diverse products, such as shampoos, creams, capsules, soaps, etc., are commercialized. \\

 "The bark of the Mimosa tenuiflora (Willd.) Poiret (Leguminoseae) tree, known as tepescohuite in Mexico, is commonly used in this country and in Central America to elaborate different products for the treatment of skin burns and lesions. The cicatrizing properties of extracts obtained from this bark have been scientifically studied, attributing the main biological activity to its tannin and saponin content. Studies include clinical trials of phytodrugs based on Mimosae tenuiflora bark extracts for treatment of venous leg ulcerations... The chemical studies performed demonstrated that tannins represent the major component group in the bark. Its content in genuine tepescohuite is 16% and is mainly composed of proanthocyanidins, a condition permitting a tannin-based chemical-control method for fingerprinting the plant drug. Contrariwise, the saponin concentration in Mimosae tenuiflora bark is extremely low..." \\

 "Yurema is the name of a plant, a deity, certain geographical areas and a sacramental beverage that is made from the root bark of Mimosa tenuiflora (Willd.) Poir. This species may be identical to Mimosa hostilis
 (Mart.) Benth. The beverage, as jurema preta, vinho da jurema and other names, is still used by people of Northeastern Brazil for medico-religious purposes, and may contain other plant additives... Yurema is still used for its psychoactive properties in traditional religions of Brazil. However, a pharmacological explanation for the visionary effects from this sacred beverage is lacking, as DMT is not orally active because of its rapid enzymatic metabolism by MAO. Ayahuasca, another sacred visionary beverage from Brazil, typically contains DMT (from the leaves of Psychotria viridis) but another plant is required to render DMT orally active; Banisteriopsis caapi, which contains the potent MAO inhibitor harmine." \\

 "... β-carbolines, which could be formed endogenously from the basic tryptamines such as 5-hydroxy-tryptamine (serotonine) (Calaway, 1988; Calaway, 1994), were found in M. tenuiflora (Meckes-Lozoya et al., 1990a). The presence of these substances can result in MAO inhibition, which may lead to an increase in the amount of catecholamine in the central nervous system, provoking euphoric effects (Corbett, 1977). According to Ott (2002), there may be MAO inhibitors in the "jurema preta" extract, which would explain the observed effects. Nevertheless, the "jurema wine" is potentially visionary per se. The inactivity of some preparations, might be due to insufficient dosage. Experimental studies are necessary to test this hypothesis." \\
