Kratom comes from a tropical tree which grows in many parts of southeast Asia. The leaves of the kratom tree have medicinal properties. Kratom has been used for centuries in southeast Asia. Recently we have begun using it in the USA to help with anxiety, pain relief, energy, focus, and relaxation.
In small doses Kratom improves alertness and energy. It helps with concentration at work and stimulates the brain. In higher doses Kratom causes the body to relax and helps with sleep. Too high of a dose can cause excessive sleepiness, however. Also keep in mind that some Kratom lasts for up to 8 hours. So, if taking a higher dose for sleep make sure you can get 8 hours uninterrupted or you may wake up groggy.
There are many different types and strains of Kratom.
