Evidence-Based Benefits

  • Cognitive enhancement — a systematic review by Geng et al. (2010) of 9 RCTs found Panax ginseng improved cognitive performance, particularly working memory and reaction time
  • Fatigue reduction — Kim et al. (2013, n=90) demonstrated that 1-2g/day Korean red ginseng significantly reduced cancer-related fatigue in an RCT
  • Immune support — a 2012 meta-analysis (Seida et al.) of 65 studies found ginseng reduced the incidence and duration of colds and flu
  • Erectile dysfunction — Jang et al. (2008, meta-analysis of 7 RCTs, n=363) found Korean red ginseng significantly improved erectile function scores vs. placebo
  • Blood sugar regulation — Vuksan et al. (2008) showed that ginsenosides improve insulin sensitivity and reduce fasting blood glucose in type 2 diabetes patients

What the Research Says

Panax ginseng has one of the largest bodies of clinical research among adaptogens, with over 500 published human studies. Geng et al. (2010) conducted a systematic review of 9 RCTs and found consistent cognitive benefits. Seida et al. (2011) reviewed 65 studies on immune function and found moderate evidence for cold/flu prevention. For erectile dysfunction, Jang et al. (2008) published a meta-analysis of 7 RCTs showing significant improvement. The Korean red ginseng form (steamed) has a modified ginsenoside profile with enhanced bioactive compounds (Rg3, compound K) and is generally considered more potent.
