【Meridian Tropism】Enters the Lung and Spleen meridians. It is a moisturizing substance.
【Preceding Discussion】Danyu (Zhu Danxi) stated: "Yi Tang belongs to Earth and is formed by Fire. It easily disperses heat within dampness. Excessive consumption agitates Spleen wind and generates Stomach fire, which is the cause of dental damage."
Ao's Note: Various grains in the Materia Medica can be used to make Yi Tang, but only those made from Glutinous Rice (Nuomi) are used medicinally, because Glutinous Rice can tonify the Qi of the internal organs.
