What are kratom’s main benefits?

Kratom is used for pain, opioid use disorder, anxiety, and other conditions. However, these uses have not been studied in clinical trials. Reportedly, at lower doses, kratom produces stimulant effects (increased alertness and energy), whereas at higher doses, kratom produces sedative and pain-relieving effects. The exact doses at which kratom causes these effects is not well researched.^[1]
