Objective: To discuss the specific application of Zhuang Medicine Crystal Sugar Ye’An Decoction in senile skin pruritus and its effects on serum IgE detection level. Methods: 90 patients with senile skin pruritus admitted to our hospital from February 2019 to April 2020 were randomly grouped. The general treatment effect, itching, secondary skin lesion severity, serum IL-6, IgE level and adverse reactions between 45 patients treated with Chlorcyclizine Hydrochloride Tablets (The control group) and 45 patients treated with Crystal Sugar Ye’An Decoction were compared. Results: The total effective rate of the treatment in the observation group was 93.33%, much higher than that in the control group, 75.56%. The difference was verified and statistically significant (P<0.05). Before the treatment, the itching area, frequency, duration and severity of secondary skin lesions were at the same level (P>0.05). After the treatment, the above data were all reduced, and the reduction of the observation group was more significant than that of the control group, indicating the difference was statistically significant (P<0.05). Before the treatment, there was no difference in serum IL-6 and IgE test data between the two groups (P>0.05). After the treatment, the tendency all declined, and that of the observation group was more obvious, indicating the difference was statistically significant (P<0.05). During the experiment, no obvious adverse reactions were observed in both groups. Conclusion: In the treatment of patients with senile pruritus, the application of Zhuang Medicine Crystal Sugar Ye’An Decoction is not only safe and reliable, but can promote the improvement of patients’ symptoms, adjust the level of inflammatory factors, and enhance clinical efficacy.
