Edible Uses

Edible Parts: Seed Edible Uses: Seed - raw or cooked[46, 61, 63, 105]. Eaten raw, there is a distinct astringency, especially if the fleshy inner skin beneath the outer shell of the seed is not removed[K]. When cooked, however, and especially when baked, the seed becomes much sweeter and has a floury texture[K]. It then makes an excellent food and can be used as a staple food in much the same way as potatoes or cereals[K]. The skin (or pellicle) of the seed is easily peeled[183]. The seed is low in fats and oils but high in carbohydrates[183]. A nutritional analysis is available[218].

Medicinal Uses

Antidote Astringent Dysentery Stomachic The burrs (seed cases?) are rich in tannin and are astringent and stomachic[147, 218]. A decoction is used in the treatment of diarrhoea, uncontrollable nose bleed, dysentery, regurgitation and profound thirst[147]. The flowers are used in the treatment of scrofula[218]. The stem bark is used to treat poisoned wounds whilst the stem sap is used to treat lacquer poisoning[218].
