Answer #2: A Seris (one who was already castrated) may use this cure.

Objection: But R. Chiya bar Aba taught that [regarding Menachos,] all agree that one is liable for Mechametz (fermenting) after Mechametz, for it says "Lo Se'aseh Chometz" and "Lo Se'afeh Chometz" [to Mechayev for every step of baking, even if the dough already became Chometz];

All agree that one is liable for castration after castration - "u'Ma'uch v'Chasus v'Nasuk v'Charus" (the verse discusses blemishes of castration, it ends "... uv'Artzechem Lo Sa'asu");

Question: If one is liable for Kores (disconnecting the testicles), all the more so for Nosek (Tosfos - totally cutting them off, but they are still in the sac; Rashi - removing them from the sac) - why did the Torah need to say "v'Nasuk"?)

Answer: This teaches that one is liable for Nosek after Kores.

Answer #3: Someone too old to have children may use this cure.

Objection: But R. Yochanan said 'These [cures discusses in Gitin] returned me to my youth (fertility)!'

Answer #4: A woman may use this cure (she is not commanded to have children).

Question: According to R. Yochanan ben Berokah, who says that "...Va'Yomer Lahem Peru u'Rvu" was also said to women (they are also commanded to have children), how can we answer?

Answer #5: A woman who is sterile or too old to have children may use this cure.

(Mishnah): If one's teeth hurt, he may not Yigma (ingest) vinegar [on Shabbos];

He may eat vegetables dipped in vinegar - it is no problem if he gets healed.

If one's loins hurt, he may not anoint with wine or vinegar; he may anoint with oil, but not rose oil;

Princes may anoint their wounds with rose oil;

R. Shimon says, all of Benei Yisrael are like princes.

(Gemara - Rav Acha bar Papa) Question: Our Mishnah forbids vinegar for aching teeth - this implies that vinegar helps teeth - but it says "Ka'Chometz l'Shinayim uche'Ashan la'Einayim"!

Answer #1: The verse alludes to vinegar that comes from grapes that did not yet ripen; the Mishnah discusses vinegar from proper grapes.

Answer #2: Both discuss vinegar from proper grapes - vinegar helps for a wound, but it loosens healthy teeth [from the gums].

(Mishnah): He may not Yigma vinegar.

Contradiction (Beraisa): He may not Yigma (put in his mouth) and spit out, but he may ingest and swallow.

Resolution #1 (Abaye): Also the Mishnah forbids [only] to put in his mouth and spit out.

Resolution #2 (Rava): It forbids even to swallow, but only after eating (it is clearly to heal); the Beraisa permits before eating (this is a normal alternative to dipping in vinegar).

Question: Migo (since) it is permitted before eating, it should also be permitted after eating (even though it is clearly to heal) - Rava himself applies Migo!

(Rava): [On Yom Kipur, one may not bathe for pleasure. One may immerse in a Mikveh on Shabbos - even though this resembles fixing something, we do not forbid, because it looks like he is merely cooling off. Even though this reason does not apply to Yom Kipur (one may not enter water to cool off), it is permitted even then, for there is nothing permitted on Shabbos that is forbidden on Yom Kipur [on account of Melachah] - since it is permitted in Shabbos, it is permitted on Yom Kipur.

Answer: Rava retracted from his explanation of our Mishnah.

Question: Perhaps he retracted from saying 'Migo'!

Answer: Surely he did not, a Beraisa says so!

(Beraisa): Anyone who needs to immerse [to become permitted to her husband] may immerse normally on Tish'ah b'Av or Yom Kipur.

(Mishnah): If one's loins hurt [...R. Shimon says, all of Benei Yisrael are princes].

(R. Aba bar Zavda citing Rav): The Halachah follows R. Shimon.

Question: Rav does not hold like R. Shimon (Rashi - regarding all laws or all his leniencies of Shabbos; Tosfos - we are thinking that R. Shimon permits when he does not intend to be cured, for it is Davar she'Eino Miskaven)!

(Rav Simi bar Chiya citing Rav): It is forbidden to wrap a rag tightly in the spout of a barrel on Yom Tov [even though he does not intend to squeeze out liquid]!

Answer: Abaye and Rava both say that R. Shimon agrees about a Pesik Reisha, it is as if he intended.

Question: Rav Chiya bar Ashi said in the name of Rav that the Halachah follows R. Yehudah [regarding Davar she'Eino Miskaven], Rav Chanan bar Ami said in the name of Shmuel that the Halachah follows R. Shimon;

R. Chiya bar Avin directly cited these rulings in the name of Rav and Shmuel.

Answer (Rava and R. Chiya bar Avin): Rav says that the Halachah follows R. Shimon, but for a different reason.

Question: What does this mean?

Suggestion: R. Shimon holds that rose oil heals [nevertheless it is permitted, for we never permit something to some people and forbid it to others]; Rav permits because he holds that it does not heal.

Rejection: In the Mishnah, Chachamim permit princes to anoint their wounds with rose oil - this implies that [all agree that] it heals!

Answer: R. Shimon permits, even where rose oil is scarce [and expensive, and it is evident that he anoints to heal]; Rav permits only where it is abundant;

In Rav's area, it was abundant.

(Mishnah): One is liable for [tying] knots of camel-drivers and sailors (these will be explained);

Just like one is liable for tying them, he is liable for untying them.

R. Meir exempts for any knot that one can untie with one hand.

(Gemara) Question: What are knots of camel-drivers and sailors?

Suggestion: They are the knots tied through the ring in a camel's nose or through the ring in a mast or at the head of a ship.

Rejection: These are not permanent!

Answer: They are the rings themselves tied through the nose or through the mast or head of a ship.

(Mishnah - R. Meir): One is exempt for any knot that one can untie with one hand.

Question (Rav Achdevoy): What is R. Meir's opinion about a [tight] bow?

If he exempts because one can untie with one hand, he would also exempt for a bow;

But if he exempts because it is loose, he would Mechayev for a tight bow!

This question is not resolved.

(Mishnah): There are knots for which one is exempt, unlike those of camel-drivers and sailors:

A woman may tie the straps of her cloak, threads of her hairnet, a belt fastened by straps, laces of shoes and sandals, drawstrings on pouches of wine and oil, and a garment around a pot of meat.

R. Eliezer ben Yakov says, one may tie [a rope] in front of an animal to prevent it from going out.

(Gemara) Question: It says that there are knots for which one is exempt, unlike those of camel-drivers and sailors;

Inference: One is exempt, but they are forbidden.

Contradiction (Seifa): A woman may tie the straps of her cloak - this is l'Chatchilah!

Answer: It means, there are knots for which one is exempt, unlike those of camel-drivers and sailors, e.g. knots tied through rings a camel's nose, in a mast or at the head of a ship;

One is exempt, but they are forbidden (for sometimes one leaves them tied for a while);

Other knots are permitted - a woman may tie the straps of her cloak...
