Trifloiate jewel vine

Derris taiwaniana is a climbing shrub. It has dark brown inflated legumes that are densely covered with rough pale yellow warts. The leguminous pods contain one to five dark brown reniform seeds. The leaves have 13 to 17 papery leaflets and the flowers are lilac-colored. Rachis are 30–50 cm (12–20 in), including petiole 7–9 cm (3–4 in). Leaflet blades are elliptic-oblong to lanceolate-oblong, base cuneate to rounded, apex acute. Legume dark brown, oblong or when 1-seeded ovoid, inflated, densely covered with pale yellow warts. Pseudoracemes with two to six branches beneath new stems, 15–30 cm (6–12 in), brown tomentose; rachis nodes with two to five flowers clustered on a 1–3 mm (0.039–0.118 in) spur.

It is used in traditional Chinese medicine as a blood tonic and to induce the growth of red blood cells and as cancer therapy in a preparation called 'Jixueteng'. The crushed concoction of D. taiwaniana leaves are used by some native tribals of north-east India, and the root bark is also directly eaten for treating intestinal infection.
