This species grows wild throughout peninsular Malaysia but is also widely cultivated, especially in the northern states, owing to its economic and medicinal value. Garcinia is a large perennial plant commonly found in evergreen forests in the southern region of Thailand and Malaysia. The ripe fruits are bright orange yellow, which are sliced, dried and used in curries or stewed in plenty of sugar to be eaten.
