Doctrine of Signatures

The doctrine of signatures is a philosophy shared by herbalists from the time of Dioscurides and Galen. This doctrine states that herbs that resemble various parts of the body can be used to treat ailments of that part of the body. Examples include the plants liverwort; snakeroot, an antidote for snake venom; lungwort; bloodroot; toothwort; and wormwood, to expel intestinal parasites. A theological justification was made for this philosophy: "It was reasoned that the Almighty must have set his sign upon the various means of curing disease which he provided." The concept is still reflected in the common names of some plants whose shapes and colors reminded herbalists of the parts of the body where they were thought to do good. Scientists see the doctrine of signatures as superstition. There is no scientific evidence that plant shapes and colors help in the discovery of medical uses of plants. In similar doctrines from India, the sage Agasthiar is supposed to have had the capability to converse with plants to thus obtain from the plants which ailments and diseases they, the plants, could ameliorate and even cure.

Famous quotes containing the words doctrine of, doctrine and/or signatures:

    I prize the purity of his character as highly as I do that of hers. As a moral being, whatever it is morally wrong for her to do, it is morally wrong for him to do. The fallacious doctrine of male and female virtues has well nigh ruined all that is morally great and lovely in his character: he has been quite as deep a sufferer by it as woman, though mostly in different respects and by other processes.
    Angelina Grimké (1805–1879)

    A faith is something you die for, a doctrine is something you kill for. There is all the difference in the world.
    Tony Benn (b. 1925)

    I am not a very sentimental man; and the best sentiment I can think of is, that if you collect the signatures of all persons who are no less distinguished than I, you will have a very undistinguishing mass of names.
    Abraham Lincoln (1809–1865)
