Lore

A Southeast Asian coffee-family tree whose leaves villagers chewed for field work. The Western extract boom is a different, louder drug, and jurisdictions keep changing their minds. The plate is the tree, not a shot glass.

The Herbarium — a teaching catalog, not a clinic. Traditional use is history, not a prescription. USDA 6b dates are a week either way, not a promise. Do not eat, drink, or harvest a plant you cannot name.
