This study tested whether a herbal supplement made from deer antler, angelica root, and astragalus could reduce fatigue in people with chronic fatigue syndrome. Over 8 weeks, 80 patients took either the herbal mixture or a placebo, and researchers measured their fatigue levels and exercise capacity. The herbal supplement group showed meaningful improvements in fatigue symptoms and could exercise longer before exhaustion compared to the placebo group.
ME/CFS remains poorly understood and lacks FDA-approved pharmacological treatments, making investigation of adjunctive interventions important for patients seeking symptom management. This rigorous placebo-controlled trial provides evidence that herbal supplements warrant further investigation as potential therapeutic options, particularly for working-age populations where fatigue has substantial quality-of-life impact.
This study does not prove the herbal supplement is universally effective for all ME/CFS patients or works through specific biological mechanisms—only that it outperformed placebo on tested measures. The findings cannot establish causation of fatigue improvement or identify which component(s) of the three-herb mixture contributed to benefits. Long-term safety and sustainability of effects remain unknown, and results may not generalize to different populations or disease phenotypes.
About the PEM badge: “PEM required” means post-exertional malaise was an explicit required diagnostic criterion for participant inclusion in this study — not that PEM was studied, observed, or discussed. Studies using criteria that do not require PEM (e.g. Fukuda, Oxford) are tagged “PEM not required”. How the atlas works →
