Kratom is the name of a tree, Mitragyna speciosa, from the coffee family native to Southeast Asia. In Thailand, Indonesia, and countries alike, it is commonly known for natives to chew on the Kratom tree leaves. Its leaves are dried and brewed into a tea.
Known for its earthy taste, people who drink kratom may experience increased energy, focus, and mood-lifting effects. Kratom interacts with the opioid receptors in the brain causing an increase in both dopamine and serotonin levels. This causes those mood-lifting effects mentioned previously.
