Garcinia atroviridis (Asam Gelugor) is a large rainforest tree that usually grows to heights of more than 20 feet tall and is native to Malaysia. Its large leaves are green, oblong-lanceolate in shape. The tree produces dark red, crimson and vinous flowers. Fruit production can vary from tree to tree. But generally, Garcinia atroviridis can produce more than 20 fruits which each contain about 5 seeds. The flesh is rich in vitamins and minerals like Vitamin C, Iron, and Magnesium, as well as being a good source of healthy dietary fiber. It is also rich in Gallic Acid, which is an antioxidant and anti-inflammatory agent believed to be beneficial in controlling inflammation and boosting the immune, cardiovascular and hormone systems. Ripe fruit appears as a bright-yellow orange and has a sour taste which makes it unappetizing to eat raw. Instead of eating it raw, Asam fruit is typically sliced, dried, then stewed and used as a warm and sour ingredient in many Asian dishes such as curries and soups.
The tree is used in ethnomedical plants and its fruit is very versatile. It has been used for centuries as a digestive aid as well as for its appetite-suppressing effects. When taken in capsule form, it is recommended to take two prior to meals as a natural appetite suppressant.
Garcinia atroviridis can be grown in USDA Zones 9-10, provided it has access to full sun or semi-shade, and is watered regularly. In cold regions, it can be successfully grown in a pot, but requires protection from cold weather.
