Why are there so many herbs in your products?

Herbs are best taken in combination to boost effectiveness, and to reduce possible negative reactions.

Which herb is the active one and which one is the filler?

Health Concerns does not use fillers. Every formula is carefully designed according to the traditions of Chinese medicine and modern biochemistry.

What studies of your supplements and ingredients have been done to provide the consumer with evidence of their safety and effectiveness?

Health Concerns formulas have been developed with attention to herbal traditions and modern scientific research. It may not be possible in every case to list scientific citations. However, these sources may help you understand more about herbs and Chinese medicine. For herbs in general a good overview is "The Encyclopedia of Popular Herbs" by the Herb Research Foundation. "Chinese Herbs in the Western Clinic" was written by Health Concerns founder Andrew Gaeddert to provide information about using herbs for modern patients. For those wishing more about traditional Chinese herbs we recommend, "Chinese Herbal Medicine, Materia Medica" by Bensky, and Gamble. Herbs are rarely researched in the same fashion as drugs. This is due to a variety of reasons: herbs have been used empirically for generations; some would argue that this is more scientific than some of the new drug studies. Governments, universities, and drug companies are not willing to fund research. It should be understood that herbs are meant to be used along with changes in diet and lifestyle that are more health promoting. Studies that compare herbs, diet and lifestyle can be criticized because it is hard to determine, was it the herbs, diet, or lifestyle suggestions that contributed to the results.

Does the vegetable based tablet coating that Health Concerns uses contain either glycerine or silica?

No
