A. paniculata is probably native to India, but has been introduced and cultivated as a medicinal plant in many parts of Asia including Indo-China, China, Thailand, Peninsular Malaysia, Indonesia, the Philippines and Australia.

The petiole is short, up to 6 mm long and it is connected to the opposite one by transverse ridges. Flowers are in lax, axillary and terminal racemes or panicles combined into a pyramidal inflorescence, with 2 small bracteoles at base of the 1-7 mm long pedicel. The flowers are bisexual and zygomorphic. The sepal has 5 segments, joined at the base, with glandular and aglandular hairs.

A. paniculata is locally common and often gregarious. It exhibits weedy characteristics and occurs from sea-level up to 1600 m altitude in village groves, roadsides, waste places, open sandy locations and fields, but also in monsoon and teak forest receiving only 10-20% of full light.
