Xerostomia | Dietary Supplement: Herbal extract granule Dietary Supplement: Placebo herbal extract granule | Not Applicable |
Xerostomia is a condition related to both decrease in the amount of saliva produced and a change in its composition, therefore causing dry mouth.It can cause severe decline in quality of life and up to date, there have been few effective treatments for xerostomia.
The purpose of the current trial is to investigate the effect of herbal extract granule named Yukmijihwang-tang (YMT) on dry mouth. The trial is a randomized, double-blinded, placebo-controlled, 2-arm, 2-centered study. Ninety-six patients with xerostomia will be randomly assigned to one of the 2 groups consisting of YMT or placebo. The assigned treatments will last for 8 weeks and the follow-up period will be 2 weeks.
The primary outcomes are Visual analogue scale (VAS) for xerostomia.
The present study is designed to examine the safety and efficacy of YMT on xerostomia. Our study provides the clinical evidence of a new therapeutic strategy for xerostomia.

- Visual Analogue Scale (VAS) for xerostomia [ Time Frame: Visit 1(0week), Visit 2(4week), Visit 3(8week), Visit 4(10week) ]A 100 mm measurement instrument will be given to the patient and he will be instructed to indicate his severity of xerostomia in relation to the 2 extremes (0: no fatigue, 100: very severe fatigue).
- Unstimulated Salivary Flow Rate (USFR) and Stimulated salivary flow rate (SSFR) [ Time Frame: Visit 1(0week), Visit 2(4week), Visit 3(8week), Visit 4(10week) ]
- Residual saliva [ Time Frame: Visit 1(0week), Visit 2(4week), Visit 3(8week), Visit 4(10week) ]
