Origin: Guo's formula. When he started practicing in the U.S., Guo found that many of his patients complained of occasional sinus problems and simultaneously exhibited a need to boost immune function. Often times, patients had found only temporary relief from most treatments since those treatments did not resolve the underlying condition. Guo developed CB to address Cold style sinus plus immune function boosting. On average, a 1-2 month course of CB is most practical. After the first 1-2 months, it is best to continue the herbs for 1-2 additional months and to add GBS during that time in order to strengthen immune function.
