Mishnayos Shabbos Perek 19 Mishnah 2

When the eighth day of a baby’s life occurs on Shabbat, he must be circumcised on that day. Therefore, one performs all the necessities of the circumcision, even on Shabbat: One circumcises the foreskin, and uncovers the skin by removing the thin membrane beneath the foreskin, and sucks the blood from the wound, and places on it both a bandage [ispelanit] and cumin as a salve. If one did not grind the cumin from Shabbat eve, he chews it with his teeth and places it on the place of circumcision as a salve. If he did not mix wine and oil on Shabbat eve, a mixture designed to heal and strengthen the child, this, the wine, is placed on the wound by itself and that, the oil, is placed by itself. And on Shabbat one may not make a pouch to place over the circumcision as a bandage ab initio, but he may wrap a rag over it as a dressing. If he did not prepare the bandage on Shabbat eve by bringing it to the place where the circumcision was performed, he wraps the bandage on his finger and brings it on Shabbat, even from a different courtyard. While the Sages permitted it to be brought, they required that it be performed in an unusual fashion, by wearing it in the manner of a garment.
