I have seen many articles making the rounds that discuss the "active chemical constituents" of herbal medicines and whole foods. And why not? This is how we create and analyze western pharmaceuticals, and how we describe their mechanisms of action. Curing Chemophobia: Do Not Buy Alternative Medicine by Michelle M. Francl takes this method of distillation a step further by using it to compare ancient herbal medicine with modern western medicine.
Ms. Francl compares one molecule of methotrexate, a western pharmaceutical that can treat arthritis, with a molecule of quercetin, present in the Chinese formula Four Marvels Powder (Si Miao Wan), which can also treat arthritis. She asserts that each of these toxic molecules can have a litany of adverse effects on the body, but at least methotrexate has been studied (by western science) and dosed with precision. Why should we place more trust the more benign-sounding substance, especially because we do not know its exact dosage, and because it is not in our western medical canon?
Francl's analysis is based on the assumption that breaking down these two medical systems into isolated constituents is an accurate or equitable way to compare them. But quercetin does not equal Four Marvels Powder, just as antioxidants do no equal blueberries. This modern metonymy is not poetic. It is an expression of our limited perspective. Maybe it is even a symptom of not feeling whole. In any case, I am calling into question this popular method of analysis.
