On the DMSO + iodine, you have to buy them separately. DMSO is found at a tractor supply co. Store or similar, and Iodine is found at most grocery stores, walmart included. DMSO and iodine both have scar-tissue healing properties, but you have to be careful to clean your hands and anything you apply it to before you use it. DMSO is a penetrating agent so anything that is on your skin with a lower molar weight than it has, will be brought into your body! It’s safe enough, but be sure not to have any kind of chemicals on your skin when you apply it.
