The Constituents and Properties of Herbs: Since the 1970s, vast amounts of information have been discovered about the chemical properties of herbs, through the science of phytochemistry. Fascinatingly, what we have learned about these chemicals often reinforces the traditional uses of the various herbs. You will learn about the nutrient content of herbs as well as about various therapeutic constituents such as alkaloids, saponins, flavonoids, immune-stimulating polysaccharides, sesquiterpene lactones, tannins, essential oils, organic acids, and other valuable chemicals. Discover how these chemicals impact upon the human physiology and how a knowledge of them helps determine not only the choice of herbs in various situations, but also when not to use particular herbs. This class will specifically focus on macronutrients and micronutrients.
