Natural history

C. gouriana is a vigorous climber spreading on thickets and climbing on trees. Principally in tropical and subtropical forests.[5] It occurs up to 5,000 feet (1,500 m) in the Himalayas; in the hilly districts of the peninsula it occurs between 1,000 feet (300 m) and 3,000 feet (910 m).[9] Flowering takes place from August to February, while fruits appear from September to May.[5]

Medicinal uses

C. gouriana is recognised as a medicinal herb in traditional medicine and amongst tribal communities. It has been investigated for its medicinal properties.[10] It has been found to possess steroids and emodins as secondary metabolites.[11]

The bruised leaves and stem act as a vesicant and are poisonous.[12] In Ayurveda, the leaves of the plant have been used for treating puerperal fever and bruises.[13] Leaf paste is applied to wounds of cattle by Jatapu, Khond and Savara tribals of Andhra Pradesh, India.[5] The crushed leaves and stems are also used for treating lice in India.[11]
