I have lost my hair because of blood deficiency. I have eaten 5 6 boxes of Yangxue Shengfa capsules. There is nothing abnormal in my body. What's with the yellow urine? What are the side effects of eating this for a long time? Fundamentally treat alopecia caused by blood deficiency, that is, strengthen the body resistance to regulate the function of kidney to produce marrow and hematopoiesis, and at the same time regulate the function of spleen to digest, transport and control blood. Only when the spleen is healthy can you work easily. On the other hand, man is an inseparable organic unity of thought, spirit, soul and matter, body and internal organs. Relying solely on the external force of materials and drugs, even Chinese herbal medicines and medicated dietary supplements with minor side effects can hardly work fundamentally, because the causes of human diseases also include factors such as thoughts, emotions and behaviors, which are often the most fundamental pathogenic factors that people are usually vague and easy to ignore. Therefore, nourishing blood and promoting hair should have a good understanding of the essential characteristics of the spleen and kidney, including the five internal organs, because the five internal organs are synergistic, mutually promoting and restricting each other. If we can adapt to the nature of the five internal organs of the spleen and kidney from the aspects of mental behavior and material function, we can produce difficult-to-buy conditioning effect with little cost and no side effects, so we might as well try it. The yellowing of urine may be related to the composition of drugs. Usually, the urine color of dark food ingredients will be biased. You can observe after stopping the drug. If the color is still yellow, drinking more water will fade. If it is not good, you can go to the hospital for examination. Don't delay.
