Ear-tip blood-pricking has the effect of draining heat, subduing swelling and relieving pain (eliminating swelling and pain), and clearing the head and eyes. If the patient has some fever and other symptoms caused by fever, by releasing a certain amount of blood after the ear tip prick, it can make the heat evil go out, and after the heat evil in the body is dispersed, the patient’s above symptoms can be relieved. If the patient has swollen and painful eyes caused by heat toxicity, stabbing blood in the ear tip can reduce swelling and relieve pain (eliminating swelling and pain), and clear the head and eyes. If the patient has symptoms such as unclear vision and blurred eyes caused by cataract, the ear-tip blood-prick therapy can also be used. Note that people who are physically weak, pregnant women and those with bleeding tendency should be cautious of using blood-prick therapy. Ear tip blood-letting needs to be operated by professional doctors. If patients have the above symptoms, they should not bleed on their own and should go to regular hospitals for treatment.
