Yerba Maté

This tree, growing in South America mainly contains caffeine and teobromine with its isomer theophylline. They are the bitter alkaloids that are most extensively contained in the Cacoeba and the Peruvian and, to a lesser extent, in Yerba maté, also in the Chinese tea House, Guarani, or the Arabesque coffee tree. Discovered in 1841, it was first isolated in 1878 and synthetically made from Xanthine shortly thereafter. The SÚKL (State Drug control Office) does not mention in Decree No. 225/2008 Coll. any restrictions on daily doses of this herbal supplement.
Muira Puama (Marapuama)
