In another formula, replace Poria with Spirit of Poria (Poria cum Ramo Quercus) and add Dipsacus Root (Cynanchi Stauntonii Radix), named "Da Lao Er Wan" (Old Beater Pill). It is so named because a woman over a hundred years old beat her old son who refused to take this pill. This consists of herbs for the Hand-Foot Shaoyin (Heart-Kidney) and Taiyin (Spleen-Lung) meridians. Between the two kidneys lies the Fire of the Gate of Vitality (Mingmen), which is the True Yang of the congenital constitution. All daily human activities rely on this fire. If this fire is weak, it cannot steam and warm the Spleen and Stomach, leading to reduced food intake and daily decline of Essence and Qi. Cistanche and Morinda can enter the Blood aspect of the Kidney Meridian, Fennel enters the Qi aspect of the Kidney Meridian; together they supplement the insufficiency of the Gate of Vitality. When the fire is vigorous, the Earth element becomes strong, and the Spleen can transport and transform effectively. Prepared Rehmannia and Lycium are herbs that nourish Water; sufficient Water can balance the Fire, preventing it from becoming hyperactive and harmful. Eucommia and Achyranthes tonify the waist and knees to assist the Kidneys; Poria and Chinese Yam drain damp-heat to assist the Spleen; Cornus and Schisandra generate Lung fluids and consolidate Essence; Polygala and Acorus unblock Heart Qi to interact with the Kidney; Dates tonify Qi and nourish Blood, moisten the Lungs, and strengthen the Spleen; Immature Bitter Orange assists Yang and tonifies deficiency, fills muscles, and strengthens bones. This is a formula that balances Water and Fire and simultaneously tonifies the Spleen and Kidney.
