Mitragyna Hirsuta is a tall tree found in parts of Cambodia, Thailand, and Vietnam. It’s closely related to Mitragyna speciosa. in Thailand it’s called kra thum khok. The plant contains a number of alkaloids but the main active constituent in Mitragyna Hirsuta is Mitraphylline, which is chemically related to mitragynine and 7-hydroxymitragynine found in Kratom (Mitragyna Speciosa), but are not the same alkaloids at all.
This extract adds more of the active alkaloids back into the powder to boost its potential.
