its very simple, just get some redmond's clay or some Bentonite clay. you can just smear a fair amount on and let it dry, then shower it off. or you can make a poultice with it. put a fair amount of the clay in a small towel, place the clay directly on top of the spot, place the towel over the clay, then wrap gauze or something around it so it stays on there. you can leave that on for an hour or two. do it at home while watching a movie or something.

the clay does two things. the first is to draw out the poison, the second is to nuetralize it.

From 11th Edition of Encyclopedia Britannica 1910-1911 (Brownstein 2006:8)

“In medicine, Iodine is frequently applied externally … and in the treatment of many conditions usually classified as surgical. The usual doses of these Iodine salts are from 300mg to 900mg. Their pharmacological action is obscure just as their effects in certain diseased condition are consistently brilliant and unexampled. Our ignorance of their mode of action is cloaked by the term deobstruent, which implies that they possess the power of driving out impurities from the blood and tissues. The following is a list of the principal condition in which iodides are recognised to be of definite value: metallic poisonings, as by lead and mercury, asthma, aneurism, arteriosclerosis, angina pectoris, gout, goitre, syphilis, haemophilia, Brights’s disease (nephritis) and bronchitis.”


i would say both.
