Bulk Chinese herb preparations are one form of supplementation in Chinese herbal medicine. Others are freeze-dried concentrates, as well as various pill forms, and externally applied liniments, washes and plasters. More than three hundred Chinese herbs and medicinal substances are commonly used in herbal prescriptions that have a history of use dating back more than 2,000 years.
Today it is important that sources of these medicinals are made using highest quality raw materials and processing standards such as GMP *Good Manufacturing Practices,” which lab tests for microbial contaminants, heavy metals and pesticide residues. It is also important to be aware that no form of endangered species, pharmaceutical contaminants, lactose, corn, wheat, or sugar are part of medicinals. Over the course of history, vast experience has been gained in perfecting clinical applications, as well as in ethical, healthy sourcing of Chinese herbal medicinals.
