Garcinia pedunculata
Also known as bor thekera, Assam garcinia, large fruited garcinia, Amlavetasa, Vetasamla, Shatavedhi.
Garcinia pedunculata is a tall evergreen tree of the mangosteen family native to the humid forests and homesteads of Assam and the northeastern hills of India, bearing very large, ribbed, intensely sour fruits whose sun dried rind is a staple souring agent and folk medicine in the region, known as bor thekera. In Ayurveda the dried rind is one of the plants supplied as Amlavetasa, the sour drug of the classical texts that pierces obstructions, kindles digestion, relieves colic and breaks stones, and it is used as the sour element in digestive powders and salts. The identity of the classical Amlavetasa is contested, and this plate follows the Garcinia that the northeast Indian trade supplies.
