====== UNIT 8: Materia Medica 3 ======
===== Introduction =====
This is the third of three Materia Medica Units where we consider the importance and significance of five more medicinal plants, focusing on how and why they are in common use. We also look at some straightforward but effective home remedies including juices, powders, decoctions and syrups.
  * Thyme, Thymus vulgaris L.
  * Marshmallow, Althaea officinalis L.
  * Yarrow, Achillea millefolium L.
  * Cleavers, Galium aparine L.
  * Dandelion, Taraxacum officinale L.
==== Overview ====
For each of the five plants, we review research into the compounds they contain and consider how knowledge of the effects of whole plant extracts informs and confirms traditional use in Western herbal medicine.\\

We also:
  * Describe why the lymphatic system is given greater emphasis in traditional Western herbal medicine than other medical systems
  * Consider the treatment of infection in a holistic and dynamic way
  * Describe the concept of expectorant, and discuss traditional systems of medicine that value increased elimination of waste products
  * Describe the ‘heroic’ approach to treatment
  * Describe herbs that have a capacity for action at specific organ sites.
There will be opportunities for you to expand your sensory exploration of the subtleties of each of these medicinal plants, and thus build a more complex and nuanced understanding and relationship with each plant.\\

You will also continue to explore simple home recipes and practical pharmacy techniques, and learn how to transform a plant into something pleasant and remedial to use.
