Title: Guazuma ulmifolia
Mutamba bark is a rich source of tannins and antioxidant chemicals called proanthocyanidins. One in particular, procyanidin B-2, helps validate mutamba’s long standing use in several countries for hair loss and baldness. In 1999, researchers in Japan reported that procyanidin B-2 was a safe topical hair-growing agent. From 2000 to 2002, they published three in vitro and in vivo (in balding men) studies showing that procyanidin B-2 promoted hair cell growth and increased the total number of hairs on a designated scalp area. Researchers have determined that mutamba bark is a rich source of this natural chemical compound. Other independent research indicates that procyanidin B-2 also has antitumorous and anticancerous effects (even against melanoma) as well as lowers blood pressure and protects the kidneys. The bark also contains a chemical called kaurenoic acid which has been documented with antibacterial and antifungal properties in many studies over the years. The leaves of mutamba contain caffeine, however none has been found in the bark of the tree.
Mutamba’s main plant chemicals include: caryophyllene, catechins, farnesol, friedelin, kaurenoic acid, precocene I, procyanidin B-2, procyanidin B-5, procyanidin C-1, and sitosterol.
