I have chronic fatigue of deficent type, with yin fire flaring when I do too much exertion; I also have poor appetite. I tried Bu Zhong Yi Qi Wan and Ginseng capsules, yet they don’t give any effect. In case of Bu Zhong Yi Qi Wan they actually worsen my condition. I feel emptiness and pain in my chest. What to do, is moxa the only alternative to combat fatigue and weakness?
