This is an old idea from European and American folk medicine. It would be impossible to determine exactly when the saying started, but it's been around for a long time.
It stems from the principle of "like causes like" - toads have warts, so if you touch them you will get warts. This makes sense in some situations. For example, if you touch someone who is sick you are likely to get sick as well. A toad's "warts', however, are not really warts - they are just bumps on the skin, and are not contagious.
Toads don't cause warts. Warts come from a virus that toads don't carry.
One common superstition is that you get warts from toads. That is just not possible, warts come from a virus that frogs and toads never carry.
For the longest time, it was thought that the frogs and the toads were two different kinds of animals. All toad-like species were placed in the family of the toads, Bufonidae. This split was based on the following caracteristics:*toads have a warty skin, frogs have a smooth skin*toads have shorter hind legs, frogs longer hindlegs*toads cannot jump or swim as well as frogsSince the 80's we know that these caracteristics are spread through all the frogs and toads. There are frogs with a warty skin that cannot jump so well because of their shorter hind legs (Alytes). There are also toads with smooth skin and longer hindlegs (Atelopus). We call this diversity of caracteristics convergent evolution.Sometimes this change of vison is confusing, because species that were formerly assigned tot the toad-family, are know considered to be a frog, but the name 'toad' is still used in their common name! An example is the famous firebelly toad. This animal is, dispite its name, not a toad, but is considered a toad-like frog.
Warts are caused by a virus called human papillomavirus (HPV) that infects the top layer of skin. Warts do not come from frogs; this is a myth.
Nope. The warts may come back, but there's no connection between their removal and cancer. If you're concerned about skin cancer, talk to your doc.
No, frogs do not give you warts when you come into contact with them. Warts are caused by a virus that infects the skin, not by touching frogs.
Toads are hiding underneath stones and logs of wood, or in burrows of other animals.
Urine is normally sterile. Warts come from viral infections. HPV is a common wart producer.
Toads can be harmful to dogs if they are licked or ingested. Some toads secrete toxins through their skin that can cause a range of symptoms in dogs, such as drooling, vomiting, difficulty breathing, and in severe cases, even death. It is important to prevent dogs from coming into contact with toads to avoid potential poisoning.
No. Although frogs & toads share a common ancestor, they are now classified as completely separate species.
Genital warts don't run in the family; you must come into contact with the virus to be infected.
Toads spend most of their time on land, but have to return to ponds to breed. Their skins are very sensitive to pollution, so when the acid rain come the toads migrate to other countries where there is less acid rain fall.
