Herpes Simplex / Herpes Zoster
Herpes simplex (also called fever blister, or cold sore) is a recurrent viral infection characterized by the appearance on the skin or mucous membranes of single or multiple clusters of small vesicles, filled with clear fluid, on slightly raised inflammatory bases. Its etiology is the herpes simplex virus (herpes virus hominis, HVH).
Herpes zoster (also called Shingles, Zona, Acute Posterior Ganglionitis) is an acute infection of the CNS involving primarily the dorsal root ganglia, and characterized by a vesicular eruption and neuralgic pain in the cutaneous areas supplied by peripheral sensory nerves arising in the affected root ganglia. Herpes zoster is caused by the same virus that causes varicella. It may be activated by local lesions involving the posterior root ganglia or by systemic disease, and may occur at any age but is most common after fifty. Inflammatory changes occur in the sensory root ganglia, the posterior horn of the gray matter, the meninges, and the dorsal and ventral roots. The cutaneous eruptions are caused by an inflammatory infiltration of the epidermis and dermis, with vesicle formation resulting from serous exudate beneath the stratum corneum.
SYMPTOMS AND SIGNS:
In the herpes simplex, the lesions may appear anywhere on the skin or on mucous membranes but are most frequent on the face, especially around the mouth or on the lips, conjunctiva and cornea, or the genitals. The appearance of small tense vesicles on an erythematous base follows a short prodromal period of tingling discomfort or itching.
In the herpes zoster, prodromal symptoms of chills and fever, malaise, and GI disturbances may be present for 3 or 4 days before distinctive features of the disease develop, with or without pain along the site of the future eruption. On about the 4th or 5th day, characteristic lesions appear as crops of vesicles on an erythematous base in the cutaneous distribution of one or more posterior root ganglia. The eruptions occur most often in the thoracic region, and spread unilaterally. About the 5th day after their appearance the vesicles begin to dry and scab. Zoster may sometimes become generalized.
ETIOLOGY AND PATHOLOGY: In Chinese medicine, herpes is called Chuang (meaning of sore). The etiology and pathology of herpes simplex are due to the following factors:
- Wind - Heat factors attack the skin through the channels of lung and stomach, then accumulated at skin causing the Chuang.
- The damp - heat flows down to attack the lower parts of the body through the channels of liver and gallbladder.
- In the chronic stages, the interior heat due to the recurrent infection consumes the Yin part of the body creating interior deficient heat.
The etiology and pathology of herpes zoster are as follows:
- The interior fire due to liver stagnation combined with damp - heat from the spleen and stomach accumulated at the skin, and causes skin problems.
- People with damp - heat body type affected by external toxic factors may easily accumulate toxins at the skin causing the herpes.
- Elderly with blood deficiency and liver deficient fire can cause the body to easily catch external damp - heat or toxic factors, and cause abnormal circulation of Qi and blood.
