Gynocardia

Gynocardia is a genus of dioecious evergreen tree belonging to the Achariaceae family, containing the sole species Gynocardia odorata. The trees grow up to 30 m tall. The species is found in moist forests of mountain valleys in South Asia - India, South-east Xizang and Yunnan in China, Bangladesh, Nepal, Bhutan and Myanmar.
The seeds of this plant have been confused with "Hydnocarpus wightianus" as the chaulmoogra oil, which is used in Indian medicine to treat several skin conditions and diseases. During British rule, several British doctors studied the use of this oil in the treatment of leprosy, lupus, scrofula, and many skin diseases. The oil was prescribed for leprosy as a mixture suspended in gum or as an emulsion. However, it has later been clarified that the actual chaulmoogra referred to in Sanskrit texts for the treatment of leprosy, as "Tuvaraka" is actually "Hydnocarpus wightianus".
