| Summary: | This study investigated whether Korean red ginseng (KRG) extracts could improve sexual function in premenopausal women. Forty-one premenopausal women participated in this placebo-controlled, double-blind, and crossover clinical study with administration of either three ginseng capsules (1 g per capsule) or placebo daily. After 8 weeks of medication of KRG or placebo, medication was changed for the subjects to placebo or KRG after 2 weeks of washout period. The efficacy of KRG extracts was measured by using Female Sexual Function Index (FSFI). Results. Twenty-three women completed the study. Total FSFI scores increased after KRG treatment (from 20.13 ± 2.87 to 23.98 ± 4.10, p = 0.015) and placebo treatment (from 20.06 ± 2.64 to 23.78 ± 3.28, p = 0.003). However, this change was not significantly different between the two groups (p = 0.702). KRG treatment significantly improved sexual desire, arousal, orgasm, and satisfaction domains; however, there was no treatment effect compared with placebo. There was a case of gastric discomfort after taking KRG extracts. Oral administration of KRG extracts improved sexual function in premenopausal women; however, there were no statistical significant changes compared to placebo. It implies that KRG extracts have a substantial placebo effect in premenopausal women with sexual dysfunction.
