Lore
A living fossil with no close relatives, planted as a temple tree in China, then as a street tree that drops foul fruit on sidewalks. The medicinal leaf is a standardized extract story more than a garden tea story.
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.
