The Rules of Blood

• The blood of people and all animals, whose blood gushes out, like the chicken and goat, is Najis.
• The blood of animals, whose blood does not gush out, like the fish and mosquito, is Tahir.
• According to Ihtiyat Wajib, one must avoid eggs that have even a small drop of blood in them. However, if the blood is in the yolk of the egg, and the covering around the yolk has not broken, then the egg - white is Tahir.
• The blood that comes out from around the teeth (gums) and that mixes with saliva is Tahir when it comes out of the mouth. In the event (that the blood is mixed with saliva), it is permissible to spit it out, although it is better not to spit it out.
