Rabbis have joined the voices calling to stop the custom of “metziza b’peh,” a method of drawing blood following a circumcision. Rabbi Yonatan Raziel, an expert in performing circumcisions, has published an article in the halachic-technological paper Techumin stating that drawing blood with a small tube is the preferable method according to Jewish law (halacha). Top rabbis have allowed the tube method for roughly 200 years, he said.
The Tzohar rabbinic organization has also come out in favor of the tube method. Tzohar recently began a program to assist secular and traditional families with circumcision.
