Why is the blood viscous in cupping and bloodletting?
In general, thick blood during cupping and bloodletting may be caused by normal physiological phenomena, stagnation of qi and blood, severe cold-dampness, high blood lipid levels, or the presence of internal toxins. If any discomfort occurs during the process, it is recommended to seek medical attention promptly. The specific analysis is as follows:
1. Normal physiological phenomenon
During cupping with bloodletting, a triangular needle is typically used to quickly prick acupuncture points. After a certain amount of blood flows out, the cup is applied over the puncture site. During bleeding, coagulation factors in the blood become active, gradually causing the blood to clot. If the bloodletting lasts for a relatively long time, the blood may appear thick, which is considered a normal physiological occurrence and usually does not require special treatment.
2. Qi and Blood Stagnation
This refers to impaired circulation of qi and blood, which can result from emotional stress, invasion by external pathogens, etc., leading to blood stasis. During cupping and bloodletting, thickened clots of blood may be drawn out. Treatment may include acupuncture, and under medical guidance, herbal medicines such as Astragalus (Huangqi), Saussurea (Muxiang), Notoginseng (Sanqi), and Salvia (Danshen) may also be used.
3. Severe Cold-Dampness
If body warmth is not properly maintained or if there is underlying weakness in the internal organs, dampness and cold may invade the body and disrupt the flow of qi and blood. During cupping with bloodletting, thick blood clots may also appear. It is important to keep the body warm and, as directed by a physician, use herbs such as ginger, Atractylodes (Baizhu), and Angelica pubescens (Duhuo) for treatment.
4. High Blood Lipid Levels
Poor dietary habits may lead to increased blood viscosity and elevated blood lipid levels. During cupping and bloodletting therapy, after the skin is punctured, the流出 blood may contain viscous clots. It is advisable to maintain a healthy diet, avoid high-cholesterol foods, and engage in regular physical exercise.
5. Presence of Toxins
If bitten by venomous insects or snakes, cupping with bloodletting may help alleviate symptoms. Following cupping, dark purple blood clots may appear due to local toxin accumulation and cell necrosis. Under medical supervision, additional treatments such as local wound debridement may also be performed.
After cupping and bloodletting, care should be taken to protect the wound and prevent infection. Avoid bathing on the same day, ensure adequate rest, refrain from spicy and irritating foods, and consume more fresh fruits and vegetables.
