Experts have warned people to not to lick 'sexy pavement lichen' that supposedly acts as a natural Viagra because it contains toxic chemicals.
Lichen is a fungus that grows in forests and on roads and pavements all across the world, with a large abundance of the organism appearing in New Zealand.
The growth contains high levels of copper, lead and zinc, and people have taken to licking it due to a belief that it provides the same benefits as erectile dysfunction drugs.
