Kohki tea
Kohki tea is a Japanese herbal drink very high in antioxidant activity. Kohki tea has been sold over the counter for centuries and is standardized to contain astilbin and taxifolin. Kohki Tea extract promotes fat burning and prolongs the fat burning process[1].
Astilbin can be isolated from Kohki tea processed from Engelhardtia chrysolepis (huang-qi).[2]
