Allergic purpura belongs to the category of “blood evidence” (non-physiological hemorrhagic disease) in Chinese medicine. There is no such thing as “the best traditional Chinese medicine” because the clinical treatment of this disease needs to be considered in conjunction with the patient’s physical condition and other factors. Chinese medicine believes that this disease is mostly related to factors such as blood-heat paranoia (heat causing the blood to go out abnormally) and qi not taking in blood, etc. When treating this disease, we can choose medicines that have the function of clearing heat and cooling the blood (clearing heat to alleviate the blood-heat) and replenishing qi and taking in blood according to the evidence, such as Radix Rehmanniae Praeparata, Radix Paeoniae Lactiflorae, Radix et Rhizoma Dampaeaeaeae, Radix Et Rhizoma Atractylodis Macrocephalae and others. 1. Blood heat: This condition mainly manifests as fever, irritability, thirst, constipation, yellow urine, red tongue with yellow fur, etc. For treatment, herbs with the effects of clearing heat and cooling blood and stopping bleeding can be chosen, such as Xianhe Cao, Radix Rehmanniae Praeparata, Radix Paeoniae Lactiflorae, Radix et Rhizoma Glycyrrhizae Praeparata, Rhizoma Zingiberis, Lotus Root and so on. 2. Qi does not take in blood: this condition is mainly manifested as tiredness, shortness of breath and laziness, fatigue, lack of color, loss of appetite, etc. For treatment, you can choose medicines that have the function of replenishing qi and consolidating the blood, such as Astragalus, Radix Codonopsis, Atractylodes Macrocephalae, etc. It is recommended to go to a regular hospital for treatment under the guidance of a professional physician.
