Kratom is an extract from the tropical tree Mitragyna speciosa, a relative of the coffee plant.
Historically, manual laborers in Southeast Asia have used the compound — either chewing the leaves or making them into tea — to soothe aches and pains and boost energy levels.
As it stands, kratom is not illegal in the United States, and people can easily purchase it online.
It is most commonly available in the form of a green powdered supplement. Although manufacturers market kratom extract as safe and natural, it is far from inert.
