What occurs if i ate poison ivy?

Not recommended: Since poison ivy is highly sensitizing, i would not advise it. You will likely tolerate the first exposure but may become allergic to it later. At one time, poison ivy resin drop was used to desensitize patients with poison ivy dermatitis and apparently was well tolerated in small doses. Most people become allergic to poison ivy/oak through skin contact. Is this a dare with money on the table?
