Lore
Pacific hospitality in a muddy bowl. The root is pounded, not boiled like a European tea, and the mouth goes numb on purpose. Several countries restrict it for liver worry; the plant remains a village crop where it is the welcome.
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.
