ברכות ל"ה ב':
גוּפָא. אָמַר רַב יְהוּדָה אָמַר שְׁמוּאֵל, וְכֵן אָמַר רַבִּי יִצְחָק אָמַר רַבִּי יוֹחָנָן: שֶׁמֶן זַיִת מְבָרְכִין עָלָיו ״בּוֹרֵא פְּרִי הָעֵץ״. הֵיכִי דָּמֵי? אִילֵּימָא דְּקָא שָׁתֵי לֵיהּ מִשְׁתָּא — אוֹזוֹקֵי מַזִּיק לֵיהּ. דְּתַנְיָא: הַשּׁוֹתֶה שֶׁמֶן שֶׁל תְּרוּמָה — מְשַׁלֵּם אֶת הַקֶּרֶן, וְאֵינוֹ מְשַׁלֵּם אֶת הַחוֹמֶשׁ. הַסָּךְ שֶׁמֶן שֶׁל תְּרוּמָה — מְשַׁלֵּם אֶת הַקֶּרֶן וּמְשַׁלֵּם אֶת הַחוֹמֶשׁ.
Previously, the Gemara cited the halakha that one recites the blessing: Who creates fruit of the tree, over olive oil. The Gemara discusses the matter itself. Rav Yehuda said that Shmuel said, and so too Rabbi Yitzḥak said that Rabbi Yoḥanan said: One recites the blessing: Who creates fruit of the tree, over olive oil just as he does over the fruit itself. What are the circumstances? If you say that he drank it plain, it causes damage to the drinker. As it was taught in a baraita: One who drinks oil of teruma, while unaware that it was teruma, pays the principal and does not pay the additional fifth which is the typical penalty for unintentional misuse of consecrated property, as in that case the individual is considered to have only damaged consecrated property without deriving benefit from it. One who anoints his body with the oil of teruma pays the principal and pays the fifth, as he derived benefit from it. Apparently, one who drinks oil derives no benefit and it even causes him damage.
אֶלָּא דְּקָא אָכֵיל לֵיהּ עַל יְדֵי פַּת. אִי הָכִי, הָוְיָא לֵיהּ פַּת עִיקָּר וְהוּא טָפֵל. וּתְנַן, זֶה הַכְּלָל: כׇּל שֶׁהוּא עִיקָּר וְעִמּוֹ טְפֵלָה — מְבָרֵךְ עַל הָעִיקָּר וּפוֹטֵר אֶת הַטְּפֵלָה! אֶלָּא דְּקָא שָׁתֵי לֵיהּ עַל יְדֵי ״אֲנִיגְרוֹן״, דְּאָמַר רַבָּה בַּר שְׁמוּאֵל: ״אֲנִיגְרוֹן״ — מַיָּא דְּסָלְקָא, ״אַנְסִיגְרוֹן״ — מַיָּא
Rather, it is referring to a case where he eats the oil by dipping bread into it. If so, the bread is primary and the oil secondary, and we learned in a mishna: This is the principle: Any food that is primary, and is eaten with food that is secondary, one recites a blessing over the primary food, and that blessing exempts the secondary from the requirement to recite a blessing before eating it. A blessing need only be recited over the bread, not over the oil. Rather, it is referring to a case where he is drinking it by means of an anigeron, as Rabba bar Shmuel said: Anigeron is water in which a beet was boiled, ansigeron is the water
ל״ו א
דְּכוּלְּהוּ שִׁלְקֵי.
in which all boiled vegetables were boiled. A certain amount of oil is added to anigeron.
אִם כֵּן, הָוֵה לֵיהּ אֲנִיגְרוֹן עִיקָּר וְשֶׁמֶן טָפֵל, וּתְנַן, זֶה הַכְּלָל: כֹּל שֶׁהוּא עִיקָּר וְעִמּוֹ טְפֵלָה, מְבָרֵךְ עַל הָעִיקָּר וּפוֹטֵר אֶת הַטְּפֵלָה!
However, if so, here too, anigeron is primary and oil is secondary, and we learned in a mishna: This is the principle: Any food that is primary, and it is eaten with food that is secondary, one recites a blessing over the primary food, and that blessing exempts the secondary from the requirement to recite a blessing before eating it. One need recite a blessing only over the anigeron.
הָכָא בְּמַאי עָסְקִינַן — בְּחוֹשֵׁשׁ בִּגְרוֹנוֹ. דְּתַנְיָא: הַחוֹשֵׁשׁ בִּגְרוֹנוֹ לֹא יְעָרְעֶנּוּ בְּשֶׁמֶן תְּחִלָּה בְּשַׁבָּת, אֲבָל נוֹתֵן שֶׁמֶן הַרְבֵּה לְתוֹךְ אֲנִיגְרוֹן וּבוֹלֵעַ.
The Gemara reconciles: With what are we dealing here? With one who has a sore throat, which he is treating with oil. As it was taught in a baraita: One who has a sore throat should not, ab initio, gargle oil on Shabbat for medicinal purposes, as doing so would violate the decree prohibiting the use of medicine on Shabbat. However, he may, even ab initio, add a large amount of oil to the anigeron and swallow it. Since it is common practice to swallow oil either alone or with a secondary ingredient like anigeron for medicinal purposes, in this case one recites: Who creates fruit of the tree.
פְּשִׁיטָא! מַהוּ דְתֵימָא: כֵּיוָן דְּלִרְפוּאָה קָא מְכַוֵּין לָא לְבָרֵיךְ עֲלֵיהּ כְּלָל, קָא מַשְׁמַע לַן כֵּיוָן דְּאִית לֵיהּ הֲנָאָה מִינֵּיהּ, בָּעֵי בָּרוֹכֵי.
The Gemara challenges: This is obvious that one must recite a blessing. The Gemara responds: Lest you say: Since he intends to use it for medicinal purposes, let him not recite a blessing over it at all, as one does not recite a blessing before taking medicine. Therefore, it teaches us that, since he derived pleasure from it, he must recite a blessing over it.
Asked Rav Avraham Genechovski - How are you allowed to mix the אניגרון with a lot of שמן? Doing so would indicate that it is for refuah and the Magen Avraham writes [סי' שכ"ג סקי"ג] that you may only be toivel a כלי on Shabbos without a Bracha b/c if one makes Bracha then it is clear that he means to be מתקן the כלי which one may not do on Shabbos. Here also, by mixing a lot of שמן in the אניגרון it us clear that he is drinking this for refuah which is אסור on Shabbos? [He asked this kashya when he was in America for cancer treatments for his son, to teach you, he said, that one has to learn and be מחדש in all situations.]
Which reminds me of something that bothers me: Why do we need mikva ladies? I mean, we can toivel our כלים by ourselves??!!
