Chinese medicine believes that the black and thick blood vessels under the tongue are caused by blood stasis in the body, and the main causes of blood stasis include stasis due to deficiency, stagnation of qi, stasis due to blood cold, stasis due to blood heat, and stasis due to blood outflow.
1. Stasis due to deficiency: mainly due to deficiency of qi, which is the driving force for the normal operation of blood in the blood vessels. After deficiency of qi, the blood can not flow smoothly in the blood vessels, which will lead to dark and thick blood vessels under the tongue.
2. Qi stagnation causes stasis: Compared to Qi deficiency, Qi stagnation also causes the blood not to flow properly.
3. Cold blood causes stasis: Normal blood is warm and flowing, but when cold is felt from the outside world or when cold is generated within the body due to a deficiency of yang, the blood vessels under the tongue will be dark and thick.
4. Blood heat causes stasis: after the invasion of fire and heat, it will cause the blood fluid to be burned, and the blood will become sticky and stagnant.
5. Blood out to cause stasis: bruises, surgical wounds and other traumas can lead to blood damage and bleeding, spleen qi deficiency can not control blood, women’s menstrual dysfunction, miscarriage, etc. can also lead to bleeding, which can not be dissipated in a timely manner, will be left in the body to form blood stasis.
If you find that the blood vessels under your tongue are dark and thick, you should consult a doctor in time to clarify the cause of the disease and then give targeted treatment.
