Comment by Plants or sum on The Blade and Flower - Chapter 18

@Plants or sum Noo I think it's a way of killing yourself I think you swallow the blood and you Choke on it?

@Plants or sum  it can be very dangerous in fact, (im a doctor) 
Biting the tongue may be due to a stroke, and it may be due to the state of swallowing the tongue that leads to suffocation, but it is known that biting the tongue is always associated with mental damage that makes a person does not control his movement, in the sense that it does not bite his tongue intentionally, but it is due to the lack of control of the jaw muscles, which acquires great strength in this case. In the hospital we always suffer from cases of strokes, which include that the patient bites his tongue. It is very difficult to unlock a patient’s jaw with such strength.

I dunno if that's the case in the manhwa, but biting the tongue is a serious thing.
