Abstract

Background: Cold hypersensitivity in the hands and feet (CHHF) is a common complaint in Asian female population especially in Korea. Due to the symptoms of CHHF the quality of individual's daily life can be degraded. Ucha-Shinki-Hwan (UCHA) is widely used in the treatment of various diseases including CHHF by harmonizing Yin and Yang, and improving the vitality of whole body. However, the efficacy of UCHA as a treatment option of CHHF has not been assessed in trials. Thus, we aimed to investigate the efficacy and safety of UCHA in Korean women with CHHF through this trial.

Methods: This study will be an exploratory, randomized, double-blind, placebo-controlled, parallel-group, multicenter trial. Korean women aged 19 to 59 years who complaint with CHHF will be enrolled from 5 university affiliated Korean medicine hospitals. A total of 164 subjects will be randomly assigned to a treatment group (UCHA) or a placebo group at a 1:1 ratio. The subjects will receive 2.5 g of either UCHA or placebo three times a day for 8 weeks. The primary outcome will be evaluated with the visual analog scale score of CHHF. The secondary outcome measures will be changes in skin temperature in extremities as measured by using a thermometer and the Korean version of the World Health Organization Quality of Life Scale Abbreviated Version.

Discussion: This study will be the first trial to explore the efficacy and safety of UCHA for CHHF patient. This will provide meaningful clinical information on herbal medicine treatment of CHHF and a clinical evidence for planning a full randomized clinical trial.
