First Thing to Do.--Soak the body thoroughly with soap (green soap if you have it) and water, this softens the outer layer (epidermis). This layer covers the female parasite which burrows under it. The male does not burrow and it is therefore easier to kill. Rub the skin thoroughly with a rough towel after the soaking. This rubbing will remove the outer skin scales and with it some of the parasites. The towel should be boiled at once to prevent it from conveying the parasite to others. Then apply the ointment, which, if thoroughly applied, relieves the patient at once. The skin should be well softened and rubbed in order to open every track (burrow) of the parasite. Allow the ointment to remain on all night and use it for three or four nights successively. Ointments.--1. Simple sulphur ointment alone. 2. Oil of Cale (from Juniper) 1 dram Sulphur Ointment 2 drams Lanolin 5 drams 3. Flowers of Sulphur 6 ounces Oil of Fagi 6 ounces White Chalk 4 ounces Green Soap 16 ounces Lard 16 ounces Apply at night. This is not so strong. [SKIN DISEASES 83] 4. For children the following can be used: Sulphur 1 dram Balsam Peru 1 dram Lard 1 ounce Apply as usual. 5. The following for adults: Precipitated Sulphur 2 drams Carbonate of Potash 1 dram Lard Ointment 1-1/2 ounces Rub well into the skin. Second:--Heal the resultant sores with soothing applications like vaselin and a little camphor in it. Third:--Boil and disinfect all underwear and bedding or any article liable to give an abiding place to the parasite. It is easily cured with proper treatment. DANDRUFF (Seborrhoea).--The scurfs or scales (dandruff) upon the scalp are formed from seborrhoea. Definition.--The word seborrboea means to flow suet or fatty fluids. Seborrhoea is a functional disorder of the sebaceous gland (fatty, suet matter) and this secretion is somewhat altered in character. Varieties.--There are three varieties. These depend upon the character of the material excreted. 1. Oily seborrhoea (seborrhoea oleosa). 2. Dry seborrhoea (seborrhoea sicca). 3. Mixed type of both. Oily seborrhoea.--Symptoms.--This appears most frequently upon the nose and forehead and sometimes upon the scalp. The skin looks oily, glistening, with the appearance of dust adhering to it. Small drops of oil are seen to ooze out of the follicles and when wiped off it reforms at once. The ducts of the follicles appear gaping or they are plugged with black-heads (comedones). The hair is rendered unusually oily, when it appears on the scalp, and it is especially noticeable on bald heads. It is very common in the negro, almost natural or physiological.
