Pyrrolizidine Alkaloids: Pyrrolizidine Alkaloids are associated with the formation of occlusion (blockages) in veins. This compound is wide spread amongst Boraginaceae, Astereceae and Papilonaceae families of plants. None of these plants should be ingested.

Pyrrolizidine Alkaloids have little or no known therapeutic  value and are exceptionally toxic. Unless a herb is used for external topical application that can not be satisfied by any other means we suggest that alternatives be found.

Several countries have banned the herbal use of plants containing Pyrrolizidine Alkaloids. Keep away from children and never ingest.
