In a recent double-blind crossover trial (J Urology 2002; 168:2070-3), Korean red ginseng enhanced sexual performance (after 8 weeks) in men. There was no significant change in testosterone levels suggesting that ginseng does not alter male hormone levels.
Korean red ginseng is a safe, reasonably priced supplement intended to support healthy sexual function.* It also promotes healthy immune function,* supports stamina,* and relieves stress* and occasional fatigue.*
