Much of the teaching about herb-drug interactions in Chinese medicine has been theoretical in the past. It was reasonable to assume, for instance, that you would want to be careful of mixing blood-moving herbs with blood thinners as they might serve to unwittingly magnify the treatment effect to excess, causing damage. Updated information and documented cases now allow us to be more informed about how interactions occur in actual cases, and practical applications abound. This seminar will include the basics of pharmacokinetic and pharmacodynamic interactions and specific examples of the most important interactions every practitioner must know will be discussed, including Chinese herbs, Western herbs, herbal formulas, and more.
