Researchers tested a traditional Chinese herbal medicine called Lixu Jieyu Recipe (LJR) in 75 ME/CFS patients over 3 months. Compared to patients who received standard vitamins and supplements, those taking LJR reported significantly greater improvements in fatigue and psychological symptoms, and showed better improvements in certain immune cell counts that are often abnormal in ME/CFS.
Immune dysfunction is a hallmark of ME/CFS, and this study suggests herbal treatment may produce measurable immune cell improvements alongside symptom relief. These findings could inform future research into plant-derived immunomodulatory compounds for ME/CFS, particularly given the limited treatment options available to patients.
This study does not establish that LJR is definitively effective for ME/CFS, as it lacked a true placebo control and used subjective symptom scales vulnerable to observer bias. The short 3-month timeframe does not demonstrate long-term safety or sustained benefit. The mechanism by which LJR affects immune function remains unknown.
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 →
