According to traditional Chinese medicine, fatigue is characterized by deficiency in Qi, a physical life force related to the energy flow of the body; and RSYRT is intended to improve Qi deficiency.
Yichen Xu and colleagues from Peking University School of Oncology in Beijing, China, along with Xin Shelley Wang from the University of Texas MD Anderson Cancer Center in Houston, US, tested the safety and efficacy of the herbal mixture Ren Shen Yangrong Tang (RSYRT). They assessed the level of fatigue in cancer patients before and after RSYRT therapy.
For the study, the patients took RSYRT twice a day for six weeks. The researchers found that RSYRT was both effective and safe, with no evidence of toxicity in any of the cancer patients.
The study is published in the Journal of Alternative and Complementary Medicine
