Closely approaching in their nature to these various kinds of poisons, are those which have been devised by man for his own destruction. In the number of antidotes to all these artificial poisons as well as to the spells of sorcery, the very first place must be accorded to the moly[1] of Homer; next to which come the mithridatia,[2] scordotis,[3] and centaury. The seed of betony carries offail kinds of noxious substances by stool; being taken for the purpose in honied wine or raisin wine, or else pulverized, and taken, in doses of one drachma, in four cyathi of old wine: in this last case, however, the patient must bring it off the stomach by vomit and then repeat the dose. Persons who accustom themselves to take this plant daily, will never experience any injury, they say, from substances of a poisonous nature.

When a person has taken poison, one most powerful remedy is aristolochia,[4] taken in the same proportions as those used for injuries inflicted by serpents.[5] The juice, too, of cinquefoil is given for a similar purpose; and in both cases, after the patient has vomited, agaric is administered, in doses of one denarius, in three cyathi of hydromel.
