This is a very....very, deep rabbit hole(s) you are peering into but I feel it is a good direction (IN sight). In homeopathy school I learned that people respond differently to the same insults though there are patterns- and patterns within patterns. For example a virus might inspire aches and pains in one person , nausea in another, but they both might have fever. The beauty of homeopathic practice is its vast potential to integrate seemingly opposing forces through matching potentialities as it relies on specificity to be effective including timing and potency (across a very specific and vast spectrum) of dose administration and requires both far and near sighted vision in the doctor and a paradigm shift in how you perceive time itself. One pattern common to Parkinsons is placebo effect which may possibly be contextualized by "consensus reality" (vis a vie 100th monkey effect). In my book this means that the sensitivity to intention is powerful with this condition.... and working in the finer more subtle aspects of medicine is good at utilizing this aspect... but power can be a tangled web when profit motives are involved - which applies to all forms of medicine and practitioners.... - the parasite/host relationship is multifaceted when it comes to parkinsons because of the catabolic nature of parkinsons itself as they feed into each other...So to my mind the question becomes : how do we shift catabolic processes to anabolic processes -gently yet radically .

There has been far reaching, painstaking methodology done to analyze properties of a large compendium of a wide variety of medicinal substances meticulously recorded in homeopathic materia medica. The beauty of this medicine is it is relatively inexpensive and accessible to all but the challenge is finding the exact right one for the right person at the right time sort of is like finding the weakness point in the center of the death star !

Here just one of many many examples used to treat parkinsons/parkinsonism: homeopathic rhus tox - Google Search
poison ivy vines - Google Search

I appreciate how you are attempting to integrate large pharma companies vs individual needs -a herculean task to be sure. Thanks for all the work you do (and your good intentions ).

P.S. "This research area and therapeutic approach recognized the inherent connection between psyche and soma. What is so obvious to us now in 2096 was obfuscated in much of the 20th century due to the then popular Newtonian mechanistic, reductionist thinking. Though this approach to science certainly has its place by helping us to understand how the parts of the whole work, it too often ignored the integrity of the whole, thereby decreasing the precision that the scientific method deserves." - Dana Ullman Homeopathy and the Future of Medicine: A Report from the Future | HuffPost
