First of all, don't touch mango again, the 3 times I tried it all ended the same way. If the pimples you're talking about are little rashes and blisters in patches, it's basically the mango that's causing all the trouble. First, don't scratch it, or you'll be in deep shit. Then go to the drugstore to buy boric acid lotion, buy it back and put it on 4 times a day, each time for 1 hour. After applying the compresses, alternately use anti-allergy ointment (miconazole clobetasol, or a kind of anti-allergy efficacy such as Eloxon can be) and glycerine lotion (glycerine can keep the skin dry and speed up the rash to go away). If you're sure it's an allergy, take a pill of Phentermine or Caritane every day. This should clear it up in 4 or 5 days. If the mango sap drops on the skin can be even more tragic ...... It is said that people who have a history of mango allergy must not touch the mango, if you eat the mango will also recur, and more than once serious, more than once difficult to cure!
