Talmud for Chullin 32:26

It was stated¹¹²Babli 81a, Tosephta 13:17. Even though a stone is not a vessel and may not be moved on the Sabbath, for hygienic purposes it is permitted. “To cleanse himself” here means to use as toilet paper. For the different stages of cleansing one may use up to three stones of varying sizes.: “A smooth¹¹³Explanation of Rashi, in Romance becudes. stone the size of an olive, or a walnut, or an egg, he may take and cleanse his feet with it. Rebbi Ismael ben Rebbi Yose said in his father’s name: up to a full hand.” Rav Jehudah said, Boetius ben Zenon was sitting and repeating before Rebbi; he said, so we are saying, it is necessary that he sit down and take it in his hand. He told him, everything is permitted except what is formed like a small sack. Rebbi Ila in the name of Rebbi Yannai: it may be like the base of a small mortar of a spice dealer. Rebbi Yose said, they only said, of a spice. But not of spices¹¹⁴Only a really small mortar whose base fits into the palm of a hand.. Rebbi Ila in the name of Rebbi Simeon ben Laqish¹¹⁵Babli 81b. Removing the grasses is harvesting. Using the stone to cleanse himself is permitted since no rabbinic prohibitions may interfere with hygienic necessities or, in the language of the Babli, “the honor of people.”: A pebble on which grasses grew he may take and cleanse his feet with it. But if he plucks off from it on the Sabbath he is liable for a purification sacrifice. Rebbi Ḥiyya stated: It is forbidden to cleanse oneself with any potsherd¹¹⁶Since it has a rough surface it may not be used even on a weekday.. Rebbi Yose ben Rebbi Abun said, not only potsherds but even handles of amphoras¹¹⁷The Babli 82a disagrees since these in general are smooth., and anything which was brought into the fire and came out again¹¹⁸According to the Babli, Ḥulin 16b, anything fired will have a rough surface and there is danger it may lead to hemorrhoids.. Rebbi Yose ben Yose said, a pebble which had been used by another person and water in a volume of less than 40 se’ah one may not use to cleanse himself¹¹⁹It seems, unless the water was poured out and any reuse would be impossible.. Rebbi Ḥanania in the name of Rebbi Mana: It is forbidden to cleanse himself with water which a dog licked. And it was stated so: One cleans himself neither with a dog’s mouth, nor in presence of a dog, nor with water which the dog had licked off, nor with water in a volume of less than 40 se’ah. And if somebody washes in the bath house or washes in a bathtub, it is bad for hemorrhoids. Rebbi Yose ben Rebbi Abun in the name of Rav Ḥuna: ¹²⁰Babli Ḥulin 16b, as tannaitic text. The blades are sharp and may be used for cutting but in general are serrated, which disqualifies them for slaughter and as surgical instruments. While one may cleanse himself with leaves, one may not use any which might cause a lesion which opens the way for pathogenic “evil spirits”. Five things were said about a reed blade: One does not use it to slaughter, nor to circumcise, nor to clean teeth with it, nor does one use it to cut meat on the table, nor does one cleanse himself, because an evil spirit resides on it.
