Lore
Cats adore it for the same reason they adore catnip: a iridoid that looks to a feline like a good idea. Medieval Europe called it all-heal and tucked it into love charms. The dried root smells of dirty socks and vanilla, and no one has ever bottled that honestly as a perfume.
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.
