The Phulwara tree also known as Cheuri (Aisandra Butyracea) is a large deciduous tree normally about 15 m in height with well-grown trees going up to 40 m. It is generally found on hill slopes and valleys along riverbanks in the sub Himalayan tract, like the states of Sikkim, Uttaranchal, and northern parts of Bengal. The butter content of the kernels is 60%. Phulwara fat is light yellow to white in colour, with a pleasant taste and odour. This fraction is then suitable for blending with SOS fractions obtained from Sal, Mango Kernel, Kokum and Dhupa fats to prepare cocoa butter substitute.
