简要总结
This study was conducted to investigate the efficacy and Safety of Nokyong Mixture Extract(CME-PI) on Promotion of Immunity
详细描述
This study was a 8 weeks, randomized, double-blind, placebo-controlled human trial. 80 subjects were randomly divided into Nokyong Mixture Extract(CME-PI) group or placebo group. The investigators measured Natural Killer cell activity, Cytokines(IL-2, IL-12, IFN-γ, TNF-α), questionnaire scores of upper airway infection.
