Moxibustion has the effect of warming the meridians and channels, activating blood circulation and removing blood stasis (promoting blood circulation and eliminating blood stasis in the body), and eliminating swelling and dissipating knots, etc. It has a certain adjunctive therapeutic effect on the swollen lymph nodes in the neck, but it should not be used as a substitute for conventional treatment. There are many causes of enlarged lymph nodes in the neck, so it is necessary to go to the hospital for examination first to clarify the cause. If it is cervical lymphadenitis, active anti-inflammatory treatment is needed; if it is cervical lymph node metastasis, active treatment of the primary lesion is needed, such as surgery, radiotherapy, chemotherapy, etc. Lymphoma and other blood system diseases may also lead to enlarged cervical lymph nodes, and bone marrow transplantation, chemotherapy and so on are often needed. Moxibustion has the function of activating blood circulation and removing blood stasis, warming the meridians and collaterals, eliminating swelling and dispersing knots, so it can be used as an adjunctive treatment for cervical lymph node enlargement, but not as the main treatment modality. If you have enlarged lymph nodes in the neck, you should go to the hospital in time to get a clear picture of the cause of the disease and standardize the treatment under the guidance of a professional doctor.
