Platinum Chemistry is the chemistry that is not taught in chemistry classes; especially, neurochemistry classes. Neurochemistry informs (influences) the reasoning, decisions, and practice of neurology, psychiatry, and pharmaceutical companies. The number of Platinum Chemistry Principles is now over one billion and growing. Virtually all neurologists, psychiatrists, and pharmaceutical companies are still ignorant of the Platinum Chemistry Principles and many people have died as a result. Note that the science of Pneumiatry includes the Platinum Chemistry Principles.
