The seeds of Argyreia nervosa contain about 0.3% ergot alkaloids, including chanoclavine, lysergol, ergotmetrine and ergine. These are all derivatives of Lysergic acid and most are jointly named lysergic acid amides (LSA). LSD (Lysergic Acid Diiethylamide) is also a lysergic acid amide and although like the natural lysergic acid amides both in structure and and pharmacological activity, it has not been found in nature. Several of the ergot alkaloids can cause constriction of bloodvessels, which may result in necrosis of the tissue and gangrene in humans and animals.
