Yu Ping Feng San (Yu Ping Feng Pian, Yu Ping Feng Wan, Jade SHIELD DECOCTION , 玉屏风片) is an ancient Chinese herbal medicine used for building up the resistance of the body against the invasion of pathogenic influences. Today it is the most recommended herbal remedy for boosting the immune defense to the infection of bacteria and viruses.†
What does it do?
In Traditional Chinese Medicine (TCM), our body is vulnerable to attacks of pathogenic influences. Normally our body forms a natural line of defense to ward off the attacks from the mouth, the nose, or the surface. When the defense gets weaker, the body is more susceptible to the bacteria and virus infection and to get cold and flu.
Yu Ping Feng Wan acts to enhance the resistance. Literally the name means Jade Screen, as if it forms a solid screen to protect the body. In many controlled clinical trials, Yu Ping Feng Wan is shown to significantly reduce the frequency of the common cold and bacteria infection in the respiratory tract in people who have chronic bronchitis or children who are susceptible to the cold or flu.1
Modern biomedical researches attribute the defense against the pathogens to the function of the immune system. The immune defense requires immunoglobulins (Ig), T lymphocytes, microphages, cytokines like interferons etc.. Many researches have been conducted to test whether Yu Ping Feng San contributes to the immune function. These studies consistently found that Yu Ping Feng San increases IgG and IgA production, enhances microphage function, and inhibits the growth of influenza virus H3N2.
Yu Ping Feng San is indicated in China Pharmacopoeia2 to invigorate the vital energy, to strengthen the body surface resistance and to stop perspiration. It is used for deficiency of the superficies to protect the body against diseased, spontaneous perspiration and aversion to wind, pale complexion or general dibility and susceptible to wind- pathogen.†
