considerations for growing and harvesting yohimbe

Pausinystalia yohimbe is an evergreen of the Rubiaceae family which can grow to a height of almost one hundred feet. Its appearance has a slight similarities to the oak tree. It has oval-shaped attenuated leaves with bushy inflorescences that produce winged seeds.

The plant leaves with petiole up to 5 mm long, glabrous, and the leaf shape is obovate, cuneate or rounded. Inflorescence is terminal or axillary, 10-21(-10) cm long and 9-15 cm wide; stipules at the base are persistent. Flowers (4-)5-merous. The outside of the calyx is densely hairy, and inside has many long hairs. The winged seeds are about 1.8-2.5 mm, and are dispersed by the wind.

The bark can be light brown or gray-brown and is about a third of an inch thick. It has horizontal and vertical fissures and is often overgrown with lichens. The tree's bark is harvested.

Yohimbe bark: Cultivation & Harvesting
considerations for growing and harvesting yohimbe

The yohimbe plant grows in warm, humid, tropical jungle climates and prefers partial shade.

This plant will grows its deep root system in hard and dry soil.

Although seed and seedlings of the yohimbe plant need light for their development, they cannot survive in full sun and will rapidly desiccate and die if over exposed. Older stems (>3 m high or 5 cm dbh), however, are capable of growing and reproducing in high light situations.

Sow seeds until large enough to transplant into individual pots. Plant out in the garden the next spring or summer.

Harvesting is only done on mature trees, and only a part of the bark is harvested in order to allow the tree to continue its growth. Once harvested, the bark is dried in the shade for a few days.

Dried yohimbe bark, cut pieces and dried yohimbe bark, powder should be stored in an airtight container in a cool, dry place.
