 insane root that takes the reason prisoner?" is believed to allude to the mandrake.

There is a good deal of evidence that mandragora was used in ancient and mediæval times not only as a soporific, but also as an anæsthetic. Dioscorides explicitly asserts this property of the root more than once. He describes a decoction of which a cupful is to be taken for severe pains, or "before amputations, or the use of the cautery, to prevent the pain of those operations." Elsewhere he alludes to its employment in parturition, and in another passage dealing with a wine prepared from the external coat of the root, says, "The person who drinks it falls in a profound sleep, and remains deprived of sense three or four hours. Physicians apply this remedy when the necessity for amputation occurs, or for applying the cautery." Pliny refers to the narcotic powers of the mandrake, and among later writers its effects are often described. Josephus mentions a plant which he calls Baaras, which cured demoniacs, but could only be procured at great risk, or by employing a dog to uproot it, the dog being killed in the process. This Baaras is supposed to have been mandrake. Dr. Lee in his Hebrew Lexicon quotes from a Persian authority an allusion to a similar root which, taken inwardly, "renders one insensible to the pain of even cutting off a limb."

Baptista Porta describes the power of the mandrake in inducing deep sleep, and in A. G. Meissner's "Skizzen," published at Carlsruhe in 1782, there is a story of Weiss, surgeon to Augustus, King of Poland and Elector of Saxony, who surreptitiously administered a potion (of what medicine is not stated) to his royal master, and during his insensibility cut off a mortifying foot.
