Herpes zoster is clinically marked by clusters of blis-ters in the form of a belt in the areas distributing with pe-ripheral nerves or certain part of skin and local burning pain. It usually appears on one side of the chest, face, eye, abdomen and thigh. TCM holds that it is caused by exogenous virulent wind, dampness and heat; or by stag-nant liver and gallbladder fire that fumigates meridians and skin with damp-heat in the spleen meridian. Pro-longed stagnation of pathogenic factors in the meridians, unsmooth circulation of qi and blood and retention of blood stasis in the meridians may lead to lingering local pain.
In the early period there is pricking pain in the af-fected part and redness of local skin, then followed by clusters of macules, sudden appearance of blisters in the form of belt and severe pain. It may be accompanied by mild fever, general discomfort and anorexia. After 2 – 3 weeks, scab is gradually formed and exfoliates without any scar. In a few cases pain may linger for a longer time.
