Phyllanthus acidus - Otaheite Gooseberry, Amlak - is very close related to Phyllanthus emblica (Amla, Amlaki), however it is much hardier plant. Known as amritphala in Sanskrit, which literally means the fruit of heaven or nectar fruit. It is so called because it is rich in many desirable properties, including medicinal.
Small to medium in size tree. Small tropical tree, to 20 feet. Fruits are borne in loose clusters, which hang from the tree trunk and main branches. Fruits are generally too tart for fresh eating but are esteemed for jellies, preserves and pastries. There are no commercial plantings; only in home gardens.
Amla fruit paste is a major ingredient of Chavyanprash, a popular Ayurvedic tonic. It is the richest source of vitamin C. Phyllanthus acidus is called Ari Nelli in Tamil, and the Phyllanthus emblica (Amlaki) is Muzhu Nelli in Tamil. Muzhu Nelli is even richer in Vitamin C etc.
