I had sent in a question about using kratom on pesach and the rav asked for more info as to what Kratom is……..Kratom (Mitragyna speciosa) is a tropical evergreen tree from Southeast Asia and is native to Thailand, Malaysia, Indonesia and Papua New Guinea. Kratom, the original name used in Thailand, is a member of the Rubiaceae family. Other members of the Rubiaceae family include coffee and gardenia. The leaves of kratom are consumed either by chewing, or by drying and, putting into capsules, tablets or extract, or by boiling into a tea. Thanks!
From what you are describing it seems to be fine to use on pesach. If it is mixed with other ingredients or processed it might need to have kosher supervision for pesach, but that would have to assessed on an individual basis.
