Distribution

Acacia concinna is widely distributed in tropical Asia and occurs throughout South-East Asia.

Uses

In India and Thailand, a decoction of young leaves is taken for body pain, headache and fever. A decoction of the pods is said to relieve biliousness and acts as a purgative. The pods are in great demand in India as an Ayurvedic product for promoting hair growth and to remove dandruff; they are sold dried and as powder in the market. They have emetic, laxative and diuretic properties and are ingested to treat constipation and kidney and bladder affections. The seeds are used externally in Thailand and India to treat skin diseases. Acacia concinna is used as a hedge plant in Indonesia, whereas the tips of stems are occasionally eaten as a vegetable. In India, tender leaves are used in chutneys; they are acidic. The fruits are sometimes used in cooking in the Philippines. The dried pods are steeped in scented water for ablution during the Water Festival and New Year celebration in Thailand.
