The leaves are oval-shaped. The bark is gray to reddish-brown. Yohimbe is used medicinally as stimulant, anti-diuretic, hypotensive, and bitter herb. It has aphrodisiac effects and is hallucinogenic. In particular, it is used in the treatment of impotence, frigidity, and angina. The bark is also a source of tannins. The wood is used as firewood and construction material. There is no known edible use of this plant.

Anaesthetic Aphrodisiac Cardiac Hallucinogenic Hypotensive Stimulant Vasodilator
The bark contains up to 6% of a mixture of indole alkaloids, the principle one being yohimbine (which is also known as aphrodine), plus pigments and tannins[254 , 418 ]. The alkaloids have a cerebral stimulant action at low doses, but are highly toxic in large doses[254 ]. Yohimbine has been shown to block the release of adrenalin and, in the correct dose, act as a sexual stimulant[238 ]. It is the source of the only clinically-proven cure for impotence and has long been used as a traditional stimulant in Africa[418 ]. Yohimbe is a bitter, warming, anti-diuretic, hypotensive and vasodilating herb with reputedly aphrodisiac effects[238 ]. It has a stimulant effect upon the heart, increasing heart rate and blood pressure; has a locally anaesthetic action similar to that of cocaine but without being mydriatic; is a mild stimulant that can help to prevent drowsiness; and is hallucinogenic. The vasodilating action of yohimbe is particularly strong on the sex organs, hence its aphrodisiac action[238 , 303 ]. The bark is taken internally, either as a powder or as a decoction. It is used particularly in the treatment of impotence, frigidity and angina[238 , 418 ]. It is also used as a performance enhancer for athletes, and as a remedy to increase the clarity of the voices of singers during long festivals[303 , 418 ]. The bark can be harvested at any time of the year[254 ]. The use of this herb is subject to legal restrictions in some countries[238 , 254 ].

An important new book from PFAF. It focuses on the attributes of plants suitable for food forests, what each can contribute to a food forest ecosystem, including carbon sequestration, and the kinds of foods they yield. The book suggests that community and small-scale food forests can provide a real alternative to intensive industrialised agriculture, and help to combat the many inter-related environmental crises that threaten the very future of life on Earth.

Other Uses
Fuel Tannin Wood
Other Uses The bark is a source of tannins[418 ]. The inner bark is utilized as straps for panniers[303 ]. The tree produces very little sap-wood, the major fraction being an ocreous-yellow heart-wood[332 ]. The wood is flexible, so is widely used as a snare-trap mechanism, whilst the young poles are used for construction purposes in traditional buildings[303 ]. The wood is used as fuel[303 , 418 ].

Cultivation details
A plant of the humid, lowland tropics, where it is found at elevations up to 500 metres[418 ]. It grows best in areas where the mean annual temperature ranges between 22 - 28°c, but can succeed at 18 - 35°c[418 ]. It prefers a mean annual rainfall in the range of 2,000 - 4,000mm, but tolerates from 1,500 - 5,000mm[418 ]. Succeeds in full sun and in partial shade[418 ]. Grows best in a fertile, moist but well-drained, medium to heavy soil with high humidity[238 , 418 ]. Prefers a pH in the range 5.5 - 7, but can tolerate 5 - 7.5[418 ]. A fast growing tree but the bole never reaches a great diameter[303 ]. The species coppices well, producing strong, highly phototrophic shoots[303 ]. The bark is harvested as the source of the alkaloid yohimbine. The main stem gives the best material but is not rich in alkaloids until the tree is 15 - 20 years of age, by which time it can contain 2 - 15% yohimbine. Bark exploitation is a seasonal activity as the yohimbine levels are highest during the rainy season[303 ]. Although the trees callus well after a small amount of bark removal, removal of large quantities of bark can lead to an attack by a small stem borer which penetrates the unprotected stem, killing the tree[303 ].
