How a bee stings?
The hurt inflicted by a bee is two-pronged. First, when bees sting they release a chemical called melittin into their victim. This venom immediately triggers pain receptors, causing a burning sensation. Second, because a bee's stinger is in fact barbed like a jagged sword, when it penetrates the victim's skin it actually dislodges from the bee, remaining there. The longer the stinger stays in the skin, the more venom is released, continuing its toxic assault for up to a minute.
