Numbness of the tongue, from the perspective of traditional Chinese medicine, is mainly divided into phlegm obstruction, deficiency of qi and blood, liver heat and wind, and other types of evidence. 1. Phlegm obstruction: If the patient’s phlegm and qi are blocked in the pericardium, “the tongue is the seedling of the heart”, it will lead to the loss of tongue nourishment, which will lead to numbness of the tongue. 2. Deficiency of blood and qi: Chinese medicine believes that if blood is deficient, the tongue will be numb, and if wind is prevalent, the tongue will be numb. When the blood flow is stagnant or the blood is deficient, the tongue cannot be nourished by the blood and qi, which will lead to numbness in the tongue. 3. Liver heat and wind bloom: It is mainly because the patient’s body is over-exuberant in yang qi, fire and heat (fire and heat), yin and blood deficiencies, etc. that cause liver yang to rise and develop unrestrictedly, which triggers liver wind and heat bloom, and also leads to numbness of the tongue in the patient. Therefore, if patients experience obvious or persistent numbness of the tongue, they should go to the hospital for timely consultation and treatment to avoid delaying their condition.
