Why does a mohel suck the blood after circumcision?

by Rabbi Yosef Loschak

This practice is part of the ritual of circumcision and it is called "Metzitza".

The source for Metzitza at a Brit is from the Talmud1 and is stated as the practiced law in the Code of Jewish Law.2

It is explained that drawing out blood prevents the blood from clotting and coagulating under the skin, which may result in inflammation and swelling.

The Code of Jewish Law does not explicitly mention how Metzitzah is to be performed. There is actually great debate amongst the Rabbis (today, as well as throughout the ages) regarding the details of Metzitza. As a result, some Mohelim use a tube, and some do it by mouth. Either way, to prevent possible transmission of diseases or infection, it is customary for the Mohel to cleanse his mouth with a disinfectant before Metzitza or before the Brit.
