Based on coincidences, the Alchemists’ Doctrine of signatures once stated that divine influence marked plants with certain features allowing an easy conclusion on their healing effects. In reality, signatures for presence of toxic or officinal constituents do exist. These signatures are resin canals (common in conifers), lacticifers (milky juice networks occurring in many plant families), plant glands (like in St. Johns Worth leaves, oil vessels (like in citrus rind) and specialized cells (idioblasts like crystal containing grit cells). These are the true signatures of plants promising unusual, and often officinal or toxic constituents.
The first part of the course is an introductory lecture. The second part consists of identifying relevant plants in the Bastyr Herb Garden and to further study them in a lab.
Student learning objectives:
Course Notes Students need notebook, lab safety requires solid shoes (no open sandals etc.). We recommend students who have an illustrated book about the wild life flora of the Pacific Northwest like the “Pojar and McKinnon”, to bring it. Some books will be provided. We also recommend bringing some lunch and something to drink, a hand lens, and pocket knife.
