Effect of Byakko-ka-Ninjin-to on Xerostomia in elderly patients

Analysis of the relationship between improvement of subjective symptom and Kampo diagnosis

Abstract

The effect of Byakko-ka Ninjin-to-on xerostomia in elderly patients and the relationship between the improvement of subjective symptoms and kampo diagnosis were studied. Xerostomia improved in 60 percent of 30 patients treated with Byakko-ka-Ninjin-to. There were significantly more patients who were less advanced in years and with a good constitution in the effective group than in the non-effective group.
Although the occurrence of appetiteoss was significantly higher in the non-effective group, there was no significant difference between the groups with respect to the occurence of constipation, diarrhoea, boborysmus, upper abdominal bloatedness or cold constitution. No significant differences between the groups were shown in the occurrence of oral kampo diagnosis such as bitter taste in the mouth, thirst, stickiness in the mouth, and mucosal dryness.
From these results it is concluded that Byakko-ka-Ninjin-to is effective for elderly patients who are not too advanced in year and who have a good constitution and (sthenia).
