The doctrine of signatures: a historical, philosophical and scientific view (I).

Richardson-Boedler C.

The evolution of the Doctrine of Signatures is presented, with reference to a physical as well as mental/spiritual mode of relating nature's medicinal substances to the human symptoms. Symbolism, intuition, biological observation, and the study of the medicinal properties serve as guides in the Doctrine of Signatures; modern science offers additional dimensions by relating physiological processes to physiology of disease.
