Ganoderma (Reishi) Herbal Formula combines the four most commonly used mushrooms in Chinese herbal medicine. Two of these, Ganoderma and Tremella, help strengthen and stabilize the organ systems of your body. The other two, Poria and Polyporus, assist the digestion and assimilation of the other mushrooms. The effect of this herbal combination is overall energy stabilization and resistance to stress and illness (tonifies Qi). Power Mushrooms can be taken with Astra 8 for additional energy and defense system (Wei Qi) enhancement.
