The healing power of shiitake mushrooms has been known for centuries throughout. Ancient healers prescribed them for a number of ailments such as fatigue, liver ailments, vision problems, sinus conditions, colds, gastro­intestinal ailments. Shiitake were also prescribed as a general prophyllactic to promote longevity, vitality, and well-being.

During the Middle Ages, remarkable, even mystical properties were attributed to St. John’s wort, thought to be best if harvested on June 24, St. John’s Day.6

This allows St. John’s wort to boost the ability of the immune system to fight infection, while at the same time decreasing the immune processes that promote inflammation in wounds and other injuries. Other studies indicate that St. John’s wort may very well play an important role in the fight against AIDS.7
