About
Sterculia is a genus of about 180 species of flowering plants in the hibiscus family Malvaceae, subfamily Sterculioideae. It was formerly placed in the now obsolete family Sterculiaceae. Members of the genus are colloquially known as tropical chestnuts. Sterculia may be monoecious or dioecious, and its flowers unisexual or bisexual.
Safety
The pods, particularly those of S. foetida, contain seeds reported to be edible, with a taste similar to cocoa. However, the oil contains cyclopropene fatty acids which could be carcinogenic or co-carcinogenic.
Gum karaya is extracted from Sterculia species, and is used as a thickener and emulsifier in foods, as a laxative, and as a denture adhesive. In India, this is sourced from: Gujarat, Maharashtra, Madras, Madhya Pradesh and Chhota Nagpur.
Where it grows
This genus is pan-tropical, with species occurring in tropical and subtropical parts of Africa, Asia, the Indo-Pacific region and the Americas.
