Burma (Myanmar), Thailand, Indo-China, the Philippines (Batan Island), southern China, Taiwan, the Ryukyu Islands and southernmost Japan.

The bark is widely used in folk medicine for its diuretic properties and as a tonic. The ashes are sometimes used to treat dropsy. In Hong Kong the fresh branchlets are used as a wash to soothe itching of the skin.

A small to medium-sized, semi-deciduous or evergreen tree up to 25 m tall, bole up to 80 cm in diameter; leaves palmately 6-8(-11)-foliolate, polymorphic, petiole 8-35 cm long, leaflets elliptical to ovate-elliptical, 7-20 cm x 3-6 cm, base attenuate, apex narrowly pointed, margin entire, glabrous, petiolules unequal, 1-5 cm long; inflorescence a well-developed panicle with hairy branches; flowers in many-flowered umbellules or sometimes solitary at the top of secondary axes; flowers 5-merous, ovary 5-8(-10)-locular; fruit globular, 3-4 mm in diameter, black. Schefflera heptaphylla is found in relatively open forest and forest edges. In southernmost Japan it occurs near sea-level; in the Ryukyu Islands up to 600 m elevation. Southward in the tropics its maximum altitude rises to 1200(-1400) m, or it even becomes entirely montane. Its distribution corresponds with the 20°C average January isotherm. Exploited from wild sources as well as from cultivation, this species can probably be grown easily at higher elevations in the Malesian region.
