The poisonous principle of the death cup is known as phallin, one of the tox-albumins, the poisons found in rattlesnakes and other venomous animals, and the poisons which produce death in cholera and diphtheria.
The phallin acts directly upon the blood corpuscles, dissolving these, so that the serum of the blood escapes from the bloodvessels into the alimentary canal and drains the whole system of its vitality.
There is no known antidote by which the effects of phallin may be counteracted. If one has eaten of the Amanita phalloides, the only chance of saving life is to remove the undigested parts from the alimentary canal by stomach-pump and oil purgatives; then, if the amount of phallin absorbed into the system is not too great, the remainder may wear itself out on the blood and the patient may recover.
The amount of the fungus which is necessary to produce death is small; even the handling of specimens and the breathing in of spores affect some people unpleasantly.
