Pausinystalia johimbe - Yohimbe

Yohimbe, (Rubiaceae), common name Pausinystalia johimbe, is a plant species native to western and central Africa (Nigeria, Cabinda, Cameroon, Congo-Brazzaville, Gabon, Equatorial Guinea). Extracts from yohimbe have been used in traditional medicine in West Africa as an aphrodisiac and have been marketed in developed countries as dietary supplements.

Description

Yohimbe is one of five Pausinystalia evergreen species growing in West and Central Africa in lowland forests. The tree grows about 30m tall, with a straight bole that is rarely larger that 50-60 cm in diameter. The bark is grey to reddish-brown, with longitudinal fissures, easy to peel and bitter-tasting. The inner bark is pinkish and fibrous. The sapwood is yellowish and the heartwood is ochre-yellow; the wood is fine-grained and relatively dense and moderately hard. The leaves grow in groups of three, with short (about 2 cm) stems. The blades are oval-shaped, 11-47 cm long and 5 - 17 cm wide.

The demand for yohimbe bark has led to over-exploitation, with possibility of long-term threat to sustainability of the species. Cameroon is the biggest exporter.

Uses

• The wood and bark are used for firewood and construction. Bark, the most commercially important product, is used in extractions to make tinctures for traditional medicine and dietary supplements.
• Extracts from the bark of yohimbe are used in West Africa as a general tonic and as an aphrodisiac.[2][3][4] Yohimbe bark and extract are widely used in manufactured dietary supplements. The levels of yohimbine present in yohimbe bark and manufactured supplements are highly variable.
• Yohimbine is used in veterinary medicine to reverse sedation in dogs, elk or deer.
