If necessary, Astragalus, Yizhi Ren and Cortex Eucommiae can be drunk together. Astragalus is sweet and slightly warm in nature, and belongs to the spleen and lung meridians. It has the effects of generating fluid and nourishing blood (replenishing the body’s water and blood), promoting stagnation and paralysis, supporting toxins and draining pus (discharging pus and toxins from the body), tonifying the qi and elevating the yang (replenishing qi in order to make yang qi rise), fixing the surface and stopping sweat (stopping sweating by consolidating the surface of the muscle), inducing water retention and reducing swellings (relieving urination and eliminating oedema), and converting sores to produce muscle growth (helping the sores to heal more quickly, and promoting the growth of new flesh). This medicine can be used to treat diseases such as spleen deficiency and weakness, edema and urination, prolapse of internal organs, blood in the stool and leakage (excessive menstrual flow or dribbling). It should be noted that it should be taken with caution when there is an abundance of superficial solidity and evil, or at the beginning of carbuncle gangrene. 2. Yi Zhi Ren is pungent in flavor and warm in nature, and belongs to the spleen and kidney meridians. It has the effect of warming the kidney to consolidate semen and reduce urination (treating spermatorrhea and enuresis by warming the kidney), warming the spleen to stop diarrhea and take in saliva (treating diarrhea and excessive salivation by warming the spleen). It can treat diseases such as cold spleen, diarrhea, excessive saliva in the mouth, and urine loss due to kidney deficiency. However, it should be taken with caution for those who have a deficiency of yin and a high level of fire. 3. Cortex Eucommiae is sweet in flavor and warm in nature. It has the effects of tonifying the liver and kidney, strengthening the muscles and bones, and stabilizing the fetus. It can be used to treat liver and kidney deficiency (weakness of liver and kidney functions), fetal leakage (small amount of vaginal bleeding in early pregnancy), restlessness of the fetus and other diseases. However, it should be taken with caution for those who are suffering from Yin deficiency and fire exuberance. If necessary, it is recommended to use it under the guidance of a medical practitioner.
