Herbs aid recovery from colds, flu and injuries. They also have been proven to enhance the digestive process while maintaining body rhythms and functions. Prescriptions are patent medicines and teas.
In traditional Chinese medicine (TCM), herbal therapies are generally formula based and single herbs are rarely used. TCM holds that every medicinal substance has its strengths and its shortcomings, and each ingredient in the formula should be carefully balanced in quality and quantity, in order to accentuate its efficacy while reducing side effects.
As TCM physicians always focus on disharmony patterns, combination of herbs should address these presentations exactly. Since a TCM formula contains multiple interactive ingredients, it is customary to rank the compositions in four groups when analyzing the role they play in the formula.
