In blood donation, the unit of blood donation is cc, which means cubic centimeter, which is equal to milliliter, that is, 1cc= 1ml. It is a habit that the blood donation unit is cc instead of ml. So 300cc is 300ml.

Generally speaking, 300cc blood donation by normal people will not have any adverse effects on the human body. On the contrary, blood donation can sometimes reduce blood viscosity and prevent venous thrombosis to some extent. At the same time, it can also promote the metabolism of the body and accelerate the discharge of metabolic wastes and toxins in the body.
