This is a non-contagious affection of the skin, characterized by the eruption of clusters of globular vesicles on inflamed patches, of irregular or rounded form and of small extent. After a few days, the vesicles may subside or burst, forming a thin brownish scab.

Of the numerous varieties of this disease it will only be necessary to mention three.

1. Herpes Phyeetenodes.

2. Herpes circennatus, or Ringworm.

3. Herpes Zoster, or Shingles.

1. Herpes Phyletenodes. This variety is characterized by clusters of globular and transparent vesicles, appearing in variable numbers upon red patches over different parts of the body. The appearance of the eruption is generally attended with considerable itching and smarting. We not unfrequently see varieties of this group appearing on the face, hands, body, extremities, and private parts.

Herpes Zoster, Zona, or Shingles. This variety usually attacks one side of the body in the shape of a semicircular belt or band, formed by several clusters of agglomerated vesicles. It is more commonly seen on the abdomen, where it begins in some part of a line, extending down the centre of the abdomen, and proceeds outwardly around the body, until it about reaches the vertebrae, thus forming a sort of half girdle. It is generally attended with considerable itching, and sometimes with more or less fever.

Treatment.* - Rhus, should there be much restlessness and fever, may be given morning, noon, and night. The ordinary forms of the disease will generally be controlled by Sulphur, Sepia or Caustieum, given in the same manner as directed in Herpes circennatus.

Should the eruption assume a dry character, Sepia, Sulphur, or Silicea may be given.

Where there is a tendency to ulceration, it may be controlled by Merc, Rhus, Sulph. or Sep. .

If Violent Itching Is Present, Nit. a or Graphites or Staphysagria will produce relief, or if warmth increases the difficulty, Clematis may be given.

Besides the remedies already enumerated, Dulc, Ars., Carb.-v,, Phos., Mez., Canth., Hep. may be indicated.
