Kratom was used for physical labor in Thailand prior to its illegal classification. Consuming Kratom lowers body temperature by approximately a degree, increases melanin production in the skin—providing more sun protection, and it is energizing both mentally and physically. It is also used to treat diarrhea, normalize blood sugar in diabetes, normalize blood pressure and battle intestinal parasites.
