Why is it that blood-supplementing herbs such as Dihuang and He Shou Wu are contraindicated during the decoction process, and all blood (pig’s blood, chicken’s blood, etc.) is contraindicated. Western medicine is mostly iron-supplementing and advocates eating iron-rich foods such as pig’s blood, because iron can synthesize heme. However, iron supplementation drugs cause stomach discomfort and iron supplementation, how much can be absorbed? Iron is available, but the other blood-supplementing materials obtained from food are reduced due to indigestion caused by iron-supplementing drugs and food, so can it really have a blood-supplementing effect? And anemia is inevitably white or yellow, in Chinese medicine, it is clear that the spleen and stomach is weak, Chinese medicine is considered to strengthen the spleen and benefit the qi, blood does not produce itself, qi can produce blood, only the spleen and stomach is healthy, food increase, food force is sufficient, Yin and blood will naturally be replenished, this is where Chinese medicine is better than Western medicine.
