Kratom is a natural drug based on the leaves and extractions of a plant of the same name that come from Southeast Asia. It is said to treat a variety of ailments and conditions, most notably withdrawal symptoms from heroin and other addictive drugs. It is also considered a mood and energy booster and is also used recreationally.1
The product contains compounds that can have psychotropic (mind-altering) effects, although the product is largely legal in the US. Mostly it is consumed for pain and relaxation, like cannabis.
