When blood comes out of the nose from the clear channel, it is called epistaxis. It is a common medical condition. It is mainly due to the fire and heat in the lung, stomach and liver, forcing the blood to travel, resulting in blood overflowing from the clear channel and flowing out of the nostrils to become epistaxis, or in some cases due to deficiency of kidney essence or deficiency of qi without intake.
