This lecture introduces participants to the Doctrine of Signatures — an ancient approach that suggests a plant’s appearance offers insight into its healing properties.

This is a way of seeing plants as teachers, each bearing visible signs of their healing gifts. Rooted in Hermetic philosophy, folk tradition, and deep observation, this presentation invites participants to attune to the symbolic language of the green world.

Explore the historical roots of this concept, its use in both folk and clinical herbalism, and practical examples of plant signatures that connect form with function.

Through stories and clinical examples, learn about how the colors, shapes, and gestures of a plant offer clues to its purpose.
