Tonka Bean

Tonka bean is the black, wrinkled seed of a large tree of the pea family, Fabaceae, native to northern South America and also called cumaru. Wikipedia says the seed smells of sweet woodruff because of its coumarin, which perfumers use, and that the old genus name Coumarouna comes from a Tupi name for the tree. Cunningham calls it feminine, with Venus and water, and lists love, money, courage and wishes. He has it carried in a sachet for love, worn for money, luck and courage, and held while a wish is visualised and then tossed into running water. Kynes adds the planet Jupiter and the element earth, and has one bean carried for courage and three kept in a white pouch as a luck talisman. All three sources warn of the hazard, which is set out in the safety notes.
