Blood Tonic Oral Liquid has the effect of benefiting Qi and replenishing Blood, which can be used clinically for dizziness, pallor, palpitation and chest tightness, little speech and laziness caused by Qi and Blood deficiency. Meanwhile, in clinical practice, it is found that for patients with mild anemia, simple application of Blood Tonic Oral Liquid can achieve good therapeutic effect. However, for patients with more severe anemia, the effect of treatment with blood tonic oral solution alone is not very obvious. For example, for patients with more severe iron deficiency anemia, they must be treated with iron supplementation drugs, such as ferrous iron in three dimensions, iron dextran, iron sucrose, etc., along with oral vitamin C treatment, while applying blood supplementation oral solution. The patient’s symptoms will be significantly improved only after comprehensive treatment by consuming more iron-rich foods in daily life.
