Edible Uses
Edible Parts: Leaves Shoots
Edible Uses: Condiment
Young leaves and shoots - raw in salads or cooked as a potherb[2, 61, 105, 183]. A report says that the young leaves contain the toxin hydrogen cyanide, though does not give any more details[240]. In small quantities this substance is fairly harmless, and has even been recommended as having health benefits, but caution is suggested if you eat these leaves[K]. The pungent leaves are used as a seasoning[183]. The seed is used as a condiment, it is a pepper substitute[2, 17, 61, 74, 148, 183].

An important new book from PFAF. It focuses on the attributes of plants suitable for food forests, what each can contribute to a food forest ecosystem, including carbon sequestration, and the kinds of foods they yield. The book suggests that community and small-scale food forests can provide a real alternative to intensive industrialised agriculture, and help to combat the many inter-related environmental crises that threaten the very future of life on Earth.
