Ergotism with vasoconstriction and gangrene has been reported through the centuries. Less well publicized are the cases of psychoses associated with convulsive ergotism. Lysergic acid amide a powerful hallucinogen having one.-tenth the hallucinogenic activity of LSD-25 is produced by natural sources. This article attempts to show that convulsive ergot psychoses are mixed psychoses caused by lysergic acid amide or similar hallucinogens combined with nervous system lesions secondary to vasoconstrictive effects of ergotoxine.
