Lymphatic and Immune Systems -Intermediate 

with Matthew Wood and Phyllis D. Light

Herbalist with 75 Years of Joint Experience 

as Consulting Herbalists & Herbal Authors

In this section we move  more fully into consideration of the immune side of this twofold system. We discuss the mast cells, the most ancient immune cells and (still) the “sentinel” of the system, watching for incoming dangers, guarding the boundaries; the arachidonic (fever cascade), the cytokines (and their famous storm), the various immune cells, their manufacture, and the importance of the bone marrow (mother of cells) and the thymus in immunity. There is also discussion of immune remedies and “tonics.”
