Edible Uses

Edible Parts: Leaves Seed Edible Uses: Leaves - cooked[177]. Used as a potherb, they are considered to be very palatable[183]. Seed - cooked. Rather small, but very nutritious, it can be ground and used as a powder. The seed can be cooked whole, and becomes very gelatinous like this, but it is rather difficult to crush all of the small seeds in the mouth and thus some of the seed will pass right through the digestive system without being assimilated[K].

Known Hazards

No members of this genus are known to be poisonous, but when grown on nitrogen-rich soils they are known to concentrate nitrates in the leaves. This is especially noticeable on land where chemical fertilizers are used. Nitrates are implicated in stomach cancers, blue babies and some other health problems. It is inadvisable, therefore, to eat this plant if it is grown inorganically.
