Kratom induces stimulant and depressant effects according to the dose used:

 

low doses (1–5 g or 0-1 heaped tsp) induce stimulant effects, reduce fatigue, alertness, and sociability and are great for lifting the mood and increasing sexual desire

 

Intermediate doses (5-10g  or 1-2 heaped teaspoons) produce pain killing, anxiety reduction and stress relieving results.

 

High Doses (10g+) Produce increasingly sedative effects, good for insomnia.
