These pages are about indexing the medical research at PubMed against natural therapies like
herbs, massage therapy, yoga, and other natural healing methods. There is a section on
molecules, hormones, biochemistry, and metabolic pathways because the research on plant-based medicine
is sometimes limited - for example, there is no formal research on cluster headaches and
kudzu, yet a search of the literature will reveal that kudzu has specific effects on the
serotonin receptors that suggests it might help treat cluster headaches (and it does).
