Shiatsu means finger pressure. It is a whole body energy technique, working along acupuncture meridians using firm gentle pressure to allow the energy to flow, so enhancing the body's natural ability to heal and balance itself.
I learnt shiatsu as part of my Macrobiotic training, and by working at a Macrobiotic Shiatsu School in Bucks County PA in the early 80's, and have been giving regular shiatsu treatments since then.
