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 the compounds mitragynine and 7-hydroxymitragynine. Although research is still in its preliminary phase and no FDA-approved uses have been issued, kratom has demonstrated efficacy in treating a variety of chronic medical conditions, with use cases ranging from pain killer to muscle relaxant.

Anresco Laboratories offers comprehensive analytical services to verify the absence of harmful contaminants in kratom products and ensure safety for human consumption.
