OBJECTIVE: To observe the curative effect of the recipe for nourishing Gan-Shen on Parkinson's disease (PD) of Gan-Shen yin deficiency type. METHODS: One hundred and twenty-one PD patients were ran-domly assigned by blocking design to the control group and the treated group in the ratio of 1:1. All were treated according to the international medication guiding principle for PD treatment, but the treated group was ad-ministered with the recipe for nourishing Gan-Shen additionally. The treatment course lasted for 12 consecutive months, and the end point was the end of the 12th month. The unified Parkinson's disease rating scale (UP-DRS) score, TCM primary and secondary symptom scores were evaluated before treatment, every 3 months of treatment and at the end point. The average daily levodopa dose and the Hoehn & Yahr grading were assessed before treatment and at the end point. RESULTS: After treatment, UPDRS score in both groups showed an ascending trend at a slower rate in the treated groups than in the control group. At the 9th and 12th month of medication, a significant difference was found in UPDRS score between the two groups (P < 0.05), and the TCM symptom score was obviously lower in the treated group than in the control group (P < 0.05). At the end point of the trial, the average daily levodopa dose used was lower in the treated group than in the control group (P < 0.05) and there was no significant difference in the Hoehn & Yahr score between the two groups (P > 0.05). CONCLUSION: The recipe for norishing Gan-Shen can slow the ascending trend of UPDRS score in the PD patients, improve the symptoms of Gan-Shen yin deficiency, and decrease the daily levodopa dose used, showing a curative effect on PD of Gan-Shen yin deficiency type.
