A comprehensive practical review of acupoint embedding as a semi-permanent acupuncture: A mini review.

Since ancient times, acupuncture has been utilized in the treatment of lots of diseases, as a part of Traditional Chinese Medicine. Acupoint embedding (AEM) therapy, known as catgut embedding, is a development of acupuncture that consists of inserting catgut or surgical threads into specific acupoints to produce continuous acupoint stimulation based on the theory of Traditional Chinese Medicine. The remaining thread in the acupoint works as a semi-permanent acupuncture needle that results in decreasing the total time of the treatment which is required for continuous manual acupuncture sessions and increasing the treatment efficacy and patients' satisfaction. In each session of AEM about twenty 1 to 2 cm-long threads-natural origin, synthetic polymer, or bioactive threads-will be inserted at the target acupoints and this process will be repeated every 3 to 4 weeks. Indications of AEM are somehow similar to manual acupuncture including obesity, pain, musculoskeletal inflammations, infertility, etc, and it cannot be performed on pregnant women and pediatrics. AEM demonstrates its therapeutic effects via modulating immune system function, alleviating body inflammatory conditions, affecting the neurohormonal system, and other mechanisms. Subcutaneous indurations, redness, bleeding, hematoma, and bruising are some adverse events reported following the AEM. In conclusion, the scientific literature suggests that AEM is a relatively safe and convenient therapy if performed by a professional skilled practitioner.
