Catuaba (Erythroxylum Catuaba)
Erythroxylum catuaba is a vigorous-growing, small tree that produces yellow and orange flowers and small, dark yellow, oval-shaped, inedible fruit. It grows in the northern part of Brazil in Amazonas, Para, Pernambuco, Bahia, Maranhao, and Alagoas.
Catuaba has a long history of use in herbal medicine as an aphrodisiac. The Tupi Indians in Brazil first discovered the aphrodisiac qualities of the plant and over the last few centuries they have composed many songs praising its wonders and abilities.
Catuaba is considered a central nervous system stimulant with aphrodisiac properties. A bark decoction is commonly used for sexual impotency, agitation, nervousness, nerve pain and weakness, poor memory or forgetfulness, and sexual weakness. According to Dr. Meira Penna, catuaba "functions as a stimulant of the nervous system, above all when one deals with functional impotence of the male genital organs... it is an innocent aphrodisiac, used without any ill effects at all." and "there is no evidence of side effects, even after long-term use."
Rizer XL's™ team determined the claims of Catuaba were in fact accurate and incorporated it in the formulation to radically raise libido and sexual desire.
