Neuropathy is defined as a functional disturbance or pathological change in the peripheral nervous system. Symptoms of neuropathy include sensory loss, muscle weakness and atrophy, and pain. Etiologies of neuropathy include trauma, infection by micro-organisms, drugs, nutritional deficiency, metabolic disorders, malignancy, and unknown causes.[2] Due to the wide range of causes, treatment varies. Herbal treatment of neuropathy focuses on relieving symptoms (pain) and the cause (such as poor circulation, increased cellular pressure, trauma, and infection).


According to traditional Chinese medicine, peripheral neuropathy, polyneuropathy, diabetic neuropathy, distal polyneuropathy, neuralgia, and fibromyalgia have various etiologies. However, they all share one common factor – pain due to blood stagnation. Therefore, Flex (NP) is formulated to treat nerve pain by activating blood circulation and eliminating blood stagnation.

        Tao Ren (Semen Persicae) and Hong Hua (Flos Carthami) are often paired together to synergistically invigorate blood circulation and remove blood stagnation. Ru Xiang (Gummi Olibanum), Mo Yao (Myrrha), Chuan Niu Xi (Radix Cyathulae), and Yan Hu Suo (Rhizoma Corydalis) together invigorate blood circulation and relieve pain. Er Cha (Catechu) and Xue Jie (Sanguis Draconis) promote the generation of new tissues. Mu Dan Pi (Cortex Moutan) moves blood and clears heat associated with local inflammation due to blood stagnation. Dang Gui (Radix Angelicae Sinensis), Dang Gui Wei (Extremitas Radix Angelicae Sinensis), Chuan Xiong (Rhizoma Chuanxiong), and Lu Lu Tong (Fructus Liquidambaris) open the channels and collaterals to relieve pain by invigorating blood circulation to the extremities. Fu Ling (Poria) is used to strengthen the middle jiao to promote absorption of the herbs.

        Da Huang (Radix et Rhizoma Rhei) clears heat, removes blood stasis and helps with blood circulation. Bai Shao (Radix Paeoniae Alba) softens the Liver and benefits the tendons and sinews to relieve tightness, numbness, tingling, and pain. Chuan Mu Xiang (Radix Vladimiriae) invigorates qi circulation in the channels to assist the overall pain-relieving effects of this formula.

        Qin Jiao (Radix Gentianae Macrophyllae), Qiang Huo (Rhizoma et Radix Notopterygii), Huang Jin Gui (Caulis Vanieriae), Mo Gu Xiao (Caulis Hyptis Capitatae), and Liu Zhi Huang (Herba Solidaginis) are used to relieve pain in the joints and extremities. Da Zao (Fructus Jujubae) and Gan Cao (Radix et Rhizoma Glycyrrhizae) are used to harmonize the formula and the
