    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 San acts to enhance the defense. 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 San 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.. Researches have been conducted to test whether Yu Ping Feng San regulates the immune function. Indeed, in cultured murine macrophages Yu Ping Feng San was found to modulate the release of cytokines.2

    Yu Ping Feng Wan is indicated in China Pharmacopoeia3 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 susceptibility to wind- pathogen.

    Yu Ping Feng Wan was the basic herbal formula recommended by Chinese health authorities to the public to enhance immune function several years ago when SARS occured in China.

    JadeDefender™ (Yu Ping Feng Pian) is rated 5.0 out of 5 by 5.
    Rated 5 out of 5 by from this product works incredibly well for me I have suffered from seasonal hay fever for many year and tried many different remedies. My acupuncturist recommended Jade Defender to me and advised that I take a small amount (5 pills) every day all year long. When hay fever season begins, I up the dose a bit. (8 pills once a day, twice if needed). This had proven to be the best herbal remedy for hay fever I have every used. I also have not had a cold or the flu since I've been taking this. I do have to take Claritin too during hay fever season, but if I wasn't taking Jade Defender, my symptoms would be much worse!! I can actually be outside now during the season and only sneeze once in awhile. Before I started Jade Defender, my symptoms were so awful, I could hardly be outside.

    Rated 5 out of 5 by from Excellent product My acupuncturist recommended this herbal formula to me to deal with spring hay fever. I take 4 pills everyday during the non-allergy months and then up the dose to 6 when Spring arrives. At the worst, I may take 6 twice a day. It has made a HUGE difference for me. I can actually be outside and not be sneezing and blowing my nose constantly. Additionally, I have not had one cold this year either when many around me have had them.
