Reaction to Poison Oak or Ivy

Medical Illustration 2015 – In Amy Martin’s book, Itchy Business, she explains the reaction process initiated by urushiol oil, the active component in poison ivy and poison oak. We are trying to emphasize that not only is this not a poison reaction, it is not useful to think of there being a substance that can be removed after a couple of hours. One of the last of the many medical illustrations and animations I have done over the years.
