Abstract:
The main cause of senile pruritus is said to be dryness of the skin. Therefore, we treated patients with xerosis senilis, a common dry skin condition, using an oral preparation of Toki-inshi and a bath preparation containing licorice extract. The effectiveness of these treatments was determined by measuring changes in the water content of the epidermal horny layer over time using an electrical measuring device. The ability of the skin to retain moisture was expressed as the degree of dryness of the skin, and the results compared with the untreated group.
When the bath preparation was used, the skin dryness improved quickly, but the effects soon disappeared when the treatment was stopped. When Toki-inshi was administered orally, the improvement was slower than with the bath preparation, but the effects did not disappear immediately when the drug was withdrawn as in the case of the bath preparation. However, since there was not necessarily agreement between improvement in skin dryness and alleviation of pruritus, factors other than skin dryness might be involved.
