Kratom, also known as Mitragyna speciosa, is a botanical herb indigenous of South East Asia whose leaves contain a spectrum of psychoactive properties. The effects of kratom have been credited to the presence of alkaloids unique to the plant, primarily mitragynine and 7-hydroxymitragynine, with use cases ranging from pain killer to muscle relaxant.

Anresco Laboratories performs comprehensive contaminant testing to ensure that every batch of product is safe for human usage.
