Halocho #2311- Is your own blood Kosher?

If one bit into food - a piece of bread or fruit, for example - and some blood (from one's gums or elsewhere) gets onto the food, one has to remove the bloody part before eating the rest.

However, one may swallow one's own blood originating in one's mouth - from bleeding gums or a cut tongue, for example - if the blood did not leave one's mouth.

Note that on Shabbat one cannot draw blood, or even suck out blood from between one's teeth.

אִם נָשַׁךְ כִּכָּר וְכַדּוֹמֶה וְיָצָא דָּם מִשִּׁנָּיו עַל גַּבֵּי הַכִּכָּר, צָרִיךְ לַחְתֹּךְ מְקוֹם הַדָּם וּלְזָרְקוֹ. אֲבָל הַדָּם שֶׁבֵּין הַשִּׁנַּיִם מוֹצְצוֹ בְּחֹל, כֵּיוָן שֶׁלֹּא פָּרַשׁ

 בשבת אָסוּר לְהוֹצִיא דָּם. וַאֲפִלּוּ דָּם שֶׁבֵּין הַשִּׁנַּיִם אָסוּר לִמְצוֹץ  בשבת
