What are the effects and functions of Tonic Spleen Drink?

Tonifying the Spleen Drink is effective in tonifying the spleen and stomach, treating symptoms such as weakness of the spleen and stomach, scanty and pale menstruation or closed menstruation, reduced diet, yellowish complexion (yellowish and lusterless), and muscular lethargy.
Tonic Spleen Drink is from “Chen Su’an Gynecological Complementary Explanation”, which is composed of Rhizoma Atractylodis Macrocephalae, Astragalus Membranaceus, Poria, Chinese yam, Guang Pi, Radix Angelicae Sinensis, Radix Rehmanniae Praeparata, Radix et Rhizoma Ginseng, Radix Aromaticae Sinensis, Radix et Rhizoma Polygoni Multiflori, Radix et Rhizoma Glycyrrhizae. This formula is made up of Si Jun Zi Tang with Astragalus, Chinese yam and licorice to tonify Spleen Qi, Xiang Fu and Guang Pi to transport the Spleen, and Angelica sinensis, Radix Rehmanniae Praeparata and Bone-setting Resin to nourish Kidney Qi.
When the stomach is strong, it can take in water and grains; when the spleen is strong, it can transport water and grains; when there is a source of blood production, menstruation can return to normal. Although Tonic Spleen Drink can nourish the spleen and stomach, it should be used after diagnosis by traditional Chinese medicine practitioners, and patients should not use or adjust the dosage of the medicine privately to avoid causing adverse reactions.
