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.
Medicines.-(Morning and evening.)
Nux vomica 3.-
Itching, either internal or external; worse when sitting, or after stimulating food or drinks; when due to coffee or strong liquors; when accompanied with pain; when due to piles, dry, or moist and bleeding, and costiveness; when due to worms.
When due to small worms, and there is fever, this may be given at night, and Ignatia in the morning, if Nux is not sufficient.
May be given after the above, if insufficient.
