What is the legal ruling on describing the act of placing a pigeon's rear end on the navel of a jaundiced baby to absorb the yellowness?

The aforementioned treatment has not been proven by correct experimentation or scientific research. Many doctors have stated their denial of it, considering it a superstition and charlatanism. They assert that the death of pigeons in the alleged experiments is not due to the absorption of the virus, but rather due to the pressure exerted by the person holding the pigeons. Anything whose direct and apparent causality has not been proven must be dismissed.
