Thoughtful physicians like Morgagni did not accredit it, or at least refused to allow it to be practiced on themselves, but its acceptance was practically universal. Probably no remedial measure ever generally used was calculated to be so effective as bleeding in producing a strong mental influence. The rather sacrificial preparations for it, the sight and the prick of the lancet, then the sight of the blood, the languor that followed, the reaction on nature's part to reproduce the lost material, all united to impress the patient's mind so deeply that it is easy to understand that all the reserve of mental force was now directed toward helping nature in the cure of whatever disease was present. Venesection itself in nine out of ten cases probably did more physical harm than good, but all the good came from its suggestion. We are now apt to think of venesection as consisting only in the removal of some blood from a favorably situated vein, but we must not forget that in the olden time they bled from many veins, and that a particular vein was picked out because it was supposed to be connected in some way with the seat of the special trouble under treatment, and as a result there was a particular appeal to mental influence. A vein on the forehead was opened for the treatment of migraine and diseases of the eyes, on the nose in case of discharge from the eyes, back of the ears in chronic headache and in stuporous conditions, or beneath the chin when there was pain in the eyes, or in the nose, or in the jaws. The cephalic vein was opened for headache and for certain affections of the eyes and ears. Altogether there were thirty different veins opened for as many maladies. It was thought extremely important in the drawing of blood from the arm that that arm should be chosen which, for some anatomical or other reason, was supposed to be the more intimately connected with the affected part of the trunk or head. The psychotherapeutic factors at work in these cases are easy to understand, and their beneficial effects gave the practice a firm foothold in medicine.
