doctrine of signatures

The doctrine of signatures is the ancient notion that the Creator had given clues to which plants should be used to treat which illnesses by shaping the plants to resemble the organs or conditions they should be used to treat. A few plants so identified turned out to have some value in treating the similar appearing body part or condition by chance. It is likely that many valuable herbs were in use before the doctrine and that the organ - plant match was made later to accommodate and validate the doctrine. While the doctrine of signatures has been totally debunked many herbal remedies used today owe their use to this notion.
