Here is another doctor-recommended home remedy. Russell Copelan, M.D., wrote about this one in the Journal of the American Academy of Dermatology.*
He suggests adhering a tiny piece of salicylic acid plaster (the kind used to treat warts) over a small splinter for twelve hours.
Within a few days the splinter should have worked its way out or moved close enough to the surface for you to easily remove it.
