What is the effect of bloodletting on the tongue coating?

Under normal circumstances, bloodletting from the tongue coating has effects such as unblocking meridians, clearing heat and detoxifying, improving circulation, reducing hypertension, and promoting cell regeneration. The specific analysis is as follows:

1. Unblocking Meridians

According to traditional Chinese medicine (TCM) theory, bloodletting from the tongue coating can promote the flow of qi and blood by unblocking meridians. This method is believed to regulate and balance the body's yin-yang and qi-blood, thereby enhancing self-recovery and healing.

2. Clearing Heat and Detoxifying

Bloodletting from the tongue coating is considered effective in clearing internal heat and toxins. In TCM, the tongue coating is seen as one manifestation of pathogenic factors accumulating in the body. Bloodletting helps eliminate internal heat toxins, thus alleviating related symptoms.

3. Improving Circulation

Bloodletting from the tongue coating can enhance local blood circulation and metabolism, increasing blood supply and oxygen delivery to the area, which aids in improving tissue nutrition and supporting recovery in the affected regions.

4. Reducing Hypertension

      Appropriate bloodletting may help relieve vascular pressure and reduce excessive vasodilation, thereby improving high blood pressure.

5. Promoting Cell Regeneration

      This method may stimulate cellular detoxification, repair, and regeneration within the body, helping prevent cardiovascular diseases.

Bloodletting from the tongue coating is a specialized TCM therapy that should be performed only by experienced TCM practitioners or acupuncturists to avoid improper procedures that could lead to physical discomfort. If any adverse symptoms occur, patients are advised to seek medical attention promptly.
