Lore

Chaste tree. Medieval monks were said to chew the seeds for the obvious reason. Mediterranean vitex is a purple-spiked shrub whose berry is a hormone-folklore spice, not a culinary one.

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.
