Devil’s claw

Lore
The Afrikaans dubbeltjiedoring is ‘devil’s thorn.’ San and Khoekhoe use of the tuber is older than the export trade. A 1950s German interest in the bitter made it a pharmacy plant. The fruit still catches sheep. The tuber should not have to catch a market.
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.
