TRADITIONAL USE
  • Centuries of use among Southeast Asian laborers and rural communities — chewed fresh, brewed as tea, or made into pastes for energy, pain relief, and as a substitute for opium during shortages
CULTURAL CONTEXT

Kratom occupies a contested legal grey zone: prohibited in some countries (including its native Thailand for decades), unregulated in others. Modern Western interest centers on its potential as a tool for managing opioid withdrawal.
