Uses
Its seeds contain strychnine and related alkaloids and have a documented history of use in traditional preparations under highly controlled, expert conditions — but the raw seed is dangerously toxic, and this is not a plant to self-treat with or forage; any traditional use requires trained expert processing.
How to Identify Kuchala
A tree with glossy, broad, strongly veined opposite leaves. Small greenish-white flowers cluster at the branch tips, followed by round, hard-shelled orange fruit resembling a small orange, containing several flat, disc-shaped, hairy seeds — the toxic part of the plant.
