An Examination of the Active Ingredient Catuaba in Extagen - Does it Help For a Huge Penis. While many of the ingredients of Extagen are quite well known, such as Yohimbe, Ginseng, and Maca, others are less well known yet still highly valued in both their native cultures as well as in the modern men's health industry for their properties. Native South American peoples valued catuaba as a male aphrodisiac and potency enhancer. The word is used to describe a number of bark products derived from several different kinds of trees native to the Amazon basin. This article examines one of the lesser known ingredients--the Brazilian bark extract catuaba. Catuaba is actually a class of supplements instead of a single extract. Since catuaba is a rather recent introduction to western alternative medicine, the exact scientific reasons for its sexual performance enhancing qualities are not well understood, though current evidence indicates that it contains several alkaloid compounds that serve to stimulate the central nervous system.

The male enhancement product Extagen contains a number of herbal extracts that have been used in folk medicine since time immemorial for the treatment of male sexual dysfunction as well as for male enhancement.
