dc.description.abstractDISTRIBUTION: To be found all over the country; next to roadsides, or other areas where the soil has been disturbed.en
dc.description.abstractBOTANICAL DESCRIPTION: General: These are pioneer plants, which are often mistaken for thistles. Leaves: The rough serrated blue leaves (A.ochroleuca) or grey-green leaves (A. mexicana) are full of prickles. Yellow latex is produced when the plants are cut. Flowers: The flowers resemble those of true poppies. Those of A. mexicana are bright yellow, while the flowers of A. ochroleuca are mainly cream-coloured. Fruit: The fruits are capsule-like and spiny and the seeds are black with indentations (like a hand grenade).en

Protopine • Cardiovascular suppression 3. Sanguinarine (predominantly in seed) • Causes dilation of capillaries and increased permeabilityen
