Note 100 — BOOK I

i.e. bile and phlegm had no existence as such before the drugs were given; they are the products of dissolved tissue. Asclepiades did not believe that diseases were due to a materia peccans, but to disturbances in the movements of the molecules (ὄγκοι) which constitute the body; thus, in opposition to the humoralists such as Galen, he had no use for drugs. cf. p. 49, note 5.
