The formula is a double tonic for the deficiency of both qi and blood, yin and yang, and Chinese medicine believes that the kidney is the main reservoir of essence, and the spleen is the source of qi and blood biochemistry. The deficiency of the spleen and kidney is the source of Qi and blood biochemistry, so the treatment of the disease is not only to tonify the spleen and kidney, but also to regulate the Yin and Yang, so often in the formula for tonifying the spleen and kidney to add products to harmonize Yin and Yang, the formula with Radix et Rhizoma Ginseng, Radix Astragali, Rhizoma Atractylodis Macrocephalae to strengthen the spleen and benefit the Qi, the Qi is strong, then the Yang will be born! The formula includes Radix et Rhizoma Ginseng, Radix et Rhizoma Atractylodis Macrocephalae, Radix et Rhizoma Tortoise, which nourishes the yin of the liver and kidneys, Radix et Rhizoma Cornu Cervi Pantotrichum, Radix et Rhizoma Epimedium, which warms the yang of the spleen and kidneys. However, the tonic products are too nourishing and greasy, so the formula is supplemented with Zedoary and Poria to lightly permeate and relieve dampness, and Salvia miltiorrhiza to invigorate the blood and open the channels. In this way, the Qi, blood, yin and yang can be protected without being too nourishing! This is a miracle formula that I have used for many years in my practice and has worked time and again.
