What is Tongkat Ali Powder?

Tongkat Ali Powder is the ground root of Eurycoma longifolia, a small understory tree of the Southeast Asian rainforest. Its Malay name, Tongkat Ali, translates literally as "Ali's walking stick," a reference to the long, straight taproot; in English it is often sold as Long Jack, and in Indonesia as Pasak Bumi.

About the plant

The root is the part traditionally used, and it is notably bitter, a character that comes from a class of compounds called quassinoids (eurycomanone is the most studied). The plant has a long documented place in Malaysian, Indonesian, and Thai folk practice and has more recently drawn a substantial modern research literature. Because the root is so bitter, most people who work with the powder encapsulate it rather than brew it.
