In the self-applied massage of the hands the system is far from esoteric. Massage your hands all over with firm pressure. Notice areas of tenderness. Return to the tender areas and administer firm pressure for a few minutes. These tender areas are associated with organs and functions that are not operating at their most healthy levels. In a series of workshops on self-massage I have asked people to find the most tender area on their hand. Each person, in turn, described the area. I would, at this point, make an educated guess as to what body area or function they had their primary health problem with. In nearly 100% of the cases the tender area that the individual described led to an accurate "educated" guess of their primary health problem This has surprised even me!
