Romans going to the temple of Asclepius (god of medicine and healing) sacrificed objects in the shape of a part of the body that was sick and needed healing. Those were votive offerings of healed parts of the body (eg. hands, legs).
In addition, the patients wrote down the history of the disease and healing in the form of inscriptions left in the temple; they threw coins into the sacred pool.
