Quizplus · Accepted Answer

The doctrine of signatures is a concept in herbal medicine that suggests that plants have physical clues or "signatures" that indicate their therapeutic properties or potential uses. These signatures might include the shape, color, or texture of a plant, or the environment in which it grows. For example, plants with heart-shaped leaves might be considered beneficial for heart health, while plants with yellow or orange roots might be used to treat liver or digestive problems. While not necessarily scientifically proven, the doctrine of signatures has been a popular concept in herbal medicine for hundreds of years.
