Deficiency of essence and blood may be related to insufficiency of the liver and kidneys (weakness of the liver and kidneys), weakness of the spleen and stomach, etc. It can be treated with medicines such as Nourishing Blood and Tonifying the Kidneys Pills and Rejuvenating the Spleen Pills as prescribed by the doctor. According to Chinese medicine, essence and blood are the basic substances for the human body to maintain life activities, and the normal operation of internal organs depends on the abundance of essence and blood. If the essence and blood are deficient, it may lead to the decline in the functions of internal organs, resulting in the appearance of pale face, dizziness and headache, lumbar and knee soreness, developmental delay, spermatorrhea and premature ejaculation in men, and menstrual irregularities in women, etc. It is usually believed that the kidney stores essence and the liver stores kidney, and the liver and kidney store essence. It is usually believed that the kidneys store essence and the liver stores blood, so the deficiency of essence and blood may be related to the insufficiency of the liver and kidneys, which can be treated with medicines such as Nourishing Blood and Tonifying Kidney Pills and Jingwu Tablets, etc., to tonify the liver and kidneys, and to benefit the essence and blood. The production of essence and blood also depends on the water and grain essence absorbed by the spleen and stomach. If the spleen and stomach are weak due to improper diet, excessive thinking, or physical weakness, they are unable to produce qi and blood, and blood cannot produce essence, resulting in deficiency of essence and blood. Medicines such as Gui Spleen Pill and Xiang Sha Nourishing Stomach Pill can be prescribed to strengthen the spleen and stomach (to restore the functions of the spleen and stomach). The above medicines should be taken under the guidance of a Chinese medicine practitioner, and should not be used blindly without authorization to avoid serious consequences.
