The San Pedro cactus is undoubtedly one of the oldest magical plants in South America, with a history of use spanning over 3,300 years. Known by the botanical name Trichocereus pachanoi, it is a fast-growing, blue-green columnar cactus that can reach heights of up to 20 feet (6 meters), growing at a rate of up to 16 inches (40 cm) per year. Its maximum height is 40 feet (12 meters).

This tree, native to West Africa (Cameroon, Equatorial Guinea, Congo, etc.), is now cultivated in several African countries to satisfy the vast global demand for yohimbe bark and its derivatives, particularly herbal yohimbe extract and pure yohimbine hydrochloride.
