Katsumadai seed is a member of the ginger family, which has green, diamond-shaped leaves and round yellow fruit, which changes color from green to yellow as it ripens. The parts of the plant used in herbal preparations are the seeds. After the fruit is gathered and dried in the sun, the seeds are removed from the fruit, then smashed or ground into a powder.

How much katsumadai seed should I take?

The typical dosage of katsumadai seed is between 3 and 6 grams, boiled in water and drunk as a decoction. If it is being combined with other herbs, katsumadai should be added to the decoction last (because of its aromatic properties).
