BBC NEWS | Snail venom painkiller launched

Prialt is a strong painkiller designed for patients suffering from chronic pain who cannot tolerate treatments like morphine.

It is based on a toxin produced by a species of snail from the Philippines.

The snail uses venom to paralyze passing fish, but scientists found chemicals in the poison could also block pain signals in the human brain.
