If you have severe reactions to mosquito bites or any other bug bites use Fenbenzenol. Just rub it on the bite or the swollen area and you'll see it actually draw the poison out, it works every time. Stops the itch or greatly reduces it, makes the inflammation / fever go away and heals quickly.

No other treatment works as good as this.

I did this with a third degree burn on my arm but with Ivermectin, DMSO, or Black Jamaican seed oil and DMSO. It heal faster then if I did the other way, which can be painful.
