Fruit contains flavonoids and saponins for blood circulation, reduces cholesterol and fat deposits in the blood vessels, acts as an antioxidant to get rid of free radicals, prevent pestilence, helps improve the immune system, prevents blood clots and strengthens heart function.

Mahoni survives in arid land and brackish sand close to the beach and likes a place with lots of direct sunlight. S. macrophylla can live for months without water. Big-leaf mahogany grows well at a maximum height of 1,500 meters above sea level, rainfall of 1,524-5,085 mm/year, and temperatures of 11-36C.











Since the 1990s, many have started to be cultivated for wood that has high economic value. The quality of hardwood and is very good for furniture, carving items and handicrafts. Often also for ruler material because size is not easily changed.

The quality of mahogany is slightly below teak (Tectona grandis) and is often dubbed the second prima donna in the world timber market. The bark is used to dye the clothes where the cloth is boiled with mahogany bark will turn yellow and not fade. Mahogany sap is used as raw material for glue and leaves for animal feed.

Seed extract is used as a vegetable pesticide to control Plutella xylostella and Crocidolomia binolalis which attack cabbage plants, especially during pests in the larval stage. The use of botanical insecticides is an alternative pest control to reduce the negative impact of using unwise synthetic insecticides.
