Bee-Patch is the yellow patch with two black lines across, symbolising the wasp. It works just a sugar cube.
When you get stung, you eventually removes the stinger, put a drop of water or salvia on the injured skin and place the patch on the skin. The molten sugar in the patch will now remove the poison through the small hole in the skin by osmosis. And the poison will be moved up into the patch.
By removing the poison, you will also remove the pain and swelling. The result is pain relief and you will not have the normal itching the next days.
