  • Cannabinoids are a group of substances found in the cannabis plant. Cannabis contains chemicals that work by binding to specific sites in the brain and on the nerves.
  • Brucine is an alkaloid resembling strychnine but it is much less potent than strychnine. Brucine causes paralysis of the peripheral nerve endings and produces violent convulsions.
  • Calotropin is an pharmacologically active compound isolated from Asclepias curasavica L. Calotropin poisoning can cause respiratory and cardiac failure.
  • Aconitine and related alkaloids found in the Aconitum species are highly toxic cardiotoxins and neurotoxins.
