Uses

Toxic parts

The pollen of this plant is a major cause of hayfever in N. America[1]. Ingesting or touching the plant can cause allergic reactions in some people[1].

Edible uses

Notes

This plant was cultivated by the pre-Columbian N. American Indians, seeds found in pre-historic sites are 4 - 5 times larger than those of the present-day wild plant, which seems to indicate selective breeding by the Indians[2]. The following report is for A. artemesifolia, it quite possibly also applies to this species[K]. An oil is obtained from the seed. It has been suggested for edible purposes because it contains little linolenic acid[3][4]. The seed contains up to 19% oil[3], it has slightly better drying properties than soya bean oil[4].

Unknown part

Oil

Material uses

A red colour is obtained from the crushed heads[2]. (This probably refers to the seed heads[K].) The sap of the plant can stain the skin red[5].

Unknown part

Medicinal uses(Warning!)

The leaves are very astringent, emetic and febrifuge[1][6]. They are applied externally to insect bites and various skin complaints, internally they are used as a tea in the treatment of pneumonia, fevers, nausea, intestinal cramps, diarrhoea and mucous discharges[1].

The juice of wilted leaves is disinfectant and is applied to infected toes[6]. A tea made from the roots is used in the treatment of menstrual disorders and stroke[1].

The pollen is harvested commercially and manufactured into pharmaceutical preparations for the treatment of allergies to the plant[1].
