People have always been seeking longevity. Traditional Chinese medicine (TCM) has had a clear understanding of aging since very ancient times dating back 5,000 years of written knowledge. To me it is curious that it recognizes the limit of the human life span as 100‐120 years, as unequivocally stated in the ancient Huang Di Internal Classic, which is known as the “Bible of TCM.” Today I am digging into the health promoting properties of mushrooms as it applies to longevity. There is research going on now regarding these mushrooms and cancer, long covid, autoimmune and more chronic diseases that are plaguing our culture right now.
