GALENIC, or GALENICAL, in medicine, is that manner of considering and treating diseases, founded on the principles of Galen, or introduced by GALEN. This author, collecting and digesting what the physicians before him had done, and explaining every thing according to the strictest doctrine of the Peripatetics, set physic on a new footing: he introduced the doctrine of the four elements; the cardinal qualities and their degrees; and the four humours or temperaments.
