Why Hot Water Extracted
Dr. Mark Stengler N.D., in his book The Health Benefits of Medicinal Mushrooms, made the observation that all of the independent scientific studies on medicinal mushrooms are based on the use of hot water extracts.
All of the references from Traditional Chinese Medicine also recommend hot water extraction when preparing medicinal mushrooms. We have absolute consensus on this issue from two distinctly different healing traditions. Why do they recommend hot water extraction?
The answer is simple and is based on two factors.
Hot water extraction is the only clinically validated method for breaking these polysaccharides out of the indigestible cell walls. Even soft mushrooms like Shiitake are prepared as a hot water extract or a tea when used medicinally.
Hot water extraction dissolves the indigestible fiber (chitin), allowing the fiber to be removed from the extract when the water is removed. This process concentrates the polysaccharides to the effective levels identified in the published research.
