Abstract

Socheongryong-tang(SCRT) is widely used to treat the common cold. The purpose of this study was to evaluate the efficacy of SCRT on Punghan type(風寒型) and Pungyeol type(風熱型) common cold. 98 registered students with commom colds of recent onset were randomized to the double blind, placebo-controlled study. SCRT extract in capsule, $5.4g(1.8g{\times}3cap)$, orally dissolved 3 times a day. The severity of illness was assessed by the physician, using a 5-point scale on start and finish. In Pungyeol type common cold, no statistically significant differences were detected between the SCRT and placebo groups for any of the measured outcomes. In Punghan type common cold, SCRT significantly reduced rhinorrhea (p=0.034) and nasal stuffiness (p=0.048) compared with placebo. This study shows that SCRT is effective in treating cold symptoms in Punghan type common cold. If patients with cold are able to be administered SCRT according to common cold type, the benefit would be expected to increase.
