Clinician Notes

For stomach and spleen qi and yang deficiency, may also be used for organ prolapse.  The spleen’s primary function is to extract the energy from the food.  A secondary function the spleen has is to hold thing in their place, this includes keep the fluids and blood in the vessels and keeping the organs in their correct places.  Therefore a chronic deficiency of the spleen qi may result in low energy, malnutrition, and may be a factor in organ prolapse.  This formula also supports the wei qi, which is responsible for many functions of the immune system from a western perspective.
