The typical dosage of homalomena is between 5 and 10 grams, usually decocted in water. A popular herbal formula combines homalomena (soaked in wine) with tiger bone, cyathula and wolfberry.

What forms of homalomena are available?

Sliced, dried homalomena rhizome can be found at some Asian markets and specialty stores. Homalomena pills and powders are also available. In addition, some vendors sell formulas that contain homalomena.
