Abstract:
Objective To investigate the therapeutic effect of Qingyan Mixture for laryngeal cough patients with lung dryness due to yin deficiency. Methods Sixty laryngeal cough patients with lung dryness due to yin deficiency were evenly randomized into treatment group and control group. The treatment group was given oral use of Qingyan Mixture, and the control group was given oral use of Ketotifen and Carbetapentane. The course of treatment for both groups lasted for 10 days. The overall therapeutic effect, and the effect on individual symptom or sign were evaluated after treatment. Results ( 1) In the treatment group, six patients were cured, 14 were markedly effective, 8 were improved, 2 were ineffective and the total effective rate was 93.3%. In the control group, one case was cured, 7 were markedly effective, 17 were improved, 5 were ineffective and the total effective rate was 83.3%. The overall clinical effect in the treatment group was significantly higher than that in the control group (P<0.01) . (2) As for the effect on individual symptom or sign, the treatment group showed stronger effect on dry cough than the control group ( P<0.01) , while differences of dry pharynx, throat itching, foreign body sensation in the throat, and pharyngeal signs were insignificant between the two groups (P>0.05) . (3) After treatment, the total scores of main symptoms were decreased in both groups (P<0.05 or P<0.01) compared with those before treatment. Conclusion Qingyan Mixture shows certain effect on relieving symptoms and signs of laryngeal cough patients with lung dryness due to yin deficiency.
