TCM therapy
Chinese herbal therapies for sciatica and lumbago usually involve warming the kidney yang, dispelling chill, clearing dampness (usually by invigorating the spleen function), and resolving wind-cold-damp complexes (e.g., relying on certain “antirheumatic” herbs).There are a wide range of potentially useful herbs for these categories of therapy, but certain ones have been emphasized in traditional and patent formulas for treating sciatica and lumbago.Other painful conditions of the lower limbs, such as gout and knee arthralgia, are treated with similar herbs and formulations.
The sciatic pain
Because of the location in the lower body, and the tendency of the pain to radiate downwards, the disorder is frequently attributed to a combination of cold and dampness: these are yin factors that have a natural downward course. Wind, an external pathogenic factor of mysterious nature, is thought to carry the pathogenic influences into the body and contribute to the variable nature of the pain.
The pain associated with sciatica follows the path of the urinary bladder meridian from the lower back down to the foot.When there is pain along this line, it shows that the Qi energy is stagnated in that area.The Qi stagnation needs to be restored in order to resume normal Qi circulation. The fact that Qi stagnation occurs in the urinary bladder's meridian does not actually suggest that there is anything wrong with the patient's bladder. What is causing the stagnation of the Qi energy can be one of many factors such as wind, damp, cold, or heat.
