Safety & Hazards
The seeds are poisonous[ 65 Title A Colour Atlas of Poisonous Plants. Publication Author Frohne. D. and Pfänder. J. Publisher Wolfe Year 1984 ISBN 0723408394 Description Brilliant. Goes into technical details but in a very readable way. The best work on the subject that I've come across so far. ]. No other specific mention of toxicity has been seen for this species, but many members of this plant family (Boraginaceae) are known to contain pyrrolizidine alkaloids. These alkaloids have a cumulative effect upon the body and, unless concentrations in a plant are high, occasional use is generally completely safe. They are derived from amino acids including ornithine. Many pyrrolizidine alkaloids have pronounced hepatic toxicity, but the lungs and other organs may be affected as well. Mutagenic and carcinogenic activities of pyrrolizidine alkaloids have also been reported[ 299 Title Protabase - Plant Resources of Tropical Africa.
