This troublesome affection is generally dependent on the presence of small worms in the lower bowel; sometimes it is due to piles; and it may also exist independently.
General Treatment.-When the itching is due to the presence of thread worms, inject warm water, in which Eau de Cologne or Spirit of turpentine (ten drops of either to the half-pint) has been mixed. When the itching is due to piles, apply Verbascum ointment (one teaspoonful of the O tincture to the ounce of vaseline or pure lard). When the itching is simple, and does not depend on another disease, sweet oil may be rubbed on the part or injected; injection of cold water, or vinegar and water may succeed, if the other means do not suffice. Coffee, salt, sweetmeats and pastry must be avoided.
