From personal dispensary to full scale factory, there are numerous principles and practices that ensure safety, accuracy and accountability in herbal medicine.  They are the least a consumer expects of you and they are mostly also required by law. This extensive review of the herbal industry will consider field and farming practices, harvesting and processing practices, how and where adulteration or contamination can occur and how to recognize it, hazard mitigation, traceability and transparency, regulations and requirements of law.  It will include a practical session where students will learn to apply organoleptic skills to raw herbs.
