Addition:
Much lymphatic congestion is a result from chemicals such as medications, preservatives, pesticides and herbicides, in combination with hydrogenated oils such as margarine, soy, flavoring additives, safflower oils, and peanut butter.
Those oils and combinations harden over time (5 – 20 years) and are not fluid at body temperature. Eating a balanced primal diet is important for slowly reversing lymphatic congestion (see the book The Recipe For Living Without Disease, Chapter 12). To help our bodies melt and dissolve hardened lymphatic congestion, I suggest taking 1 - 1 ½ hours hot baths every 3 – 4 days.
