Edible Uses

Edible Parts: Oil Seed Edible Uses: Oil Seed - raw, roasted, fried or ground into a powder[63 , 418 ]. The seeds have a pleasant flavour resembling hazel nuts. After removal of the leathery testa, the kernels can be eaten raw, roasted, fried or ground for a drink or sweets[324 , 418 ]. Under dry conditions nuts will keep for around 30 days in the capsule; shell damage or a moist environment can initiate enzyme reaction leading to acidification and rancidity of the oil[324 ]. The nuts are easily separated from the thin shell and, when dried and roasted, they can be safely stored for a long time in sealed plastic bags The seed is about 25mm long and is surrounded by a thin shell that can easily be broken with the fingers[63 ]. The seeds are a source of an edible oil rich in linoleic acid (34.4%)[324 , 418 ]. Once extracted the oil can be safely stored for a long time without turning rancid[324 ].

Medicinal Uses

Nuts and oil are an excellent cure for pulmonary complaints and dermatitis[324 ].
