Does Leviticus 14 v2-52 really work?

Leviticus 14:2-52 describes a ceremonial practice under the Mosaic Law, the Torah. It is not a medical practice, although sound medical ideas such as washing are involved. The cleansing referred to is to signify that the person was cured of leprosy and was then to be made ceremonially clean that they might again enter into the religious life of the Jews of that age, as being certified free from the disease and also as being free from the religious defilement which it brought.
