THREAD WORM OR PIN WORM.--(Oxyuris Vermicularis.)--This common worm occupies the rectum and colon. They produce great irritation and itching, particularly at night, symptoms which become intensely aggravated by the nightly migration (traveling) of the parasite. They sometimes in their travels enter the vagina. Occasionally abscesses are formed around the bowel (rectum) containing numbers of worms. The patient becomes extremely restless and irritable, for the sleep is very often disturbed, and there may be loss of appetite and also anemia. These worms are most common in children, but they can occur in all ages. The worms can easily be seen in the feces. The infection takes place through the drinking of water and possibly through salads, such as lettuce and cresses, and various other means. A person who is the subject of worms passes ova (eggs) in large numbers in the feces, and the possibility of reinfection must be guarded against very scrupulously. MOTHERS' REMEDIES.--1. Pin worms, Aloes treatment for.--"Pin worms or seat worms are usually found in children and sometime cause a great deal of annoyance to the child. They are usually very restless at night and pull at the rectum both day and night. This condition may be relieved by an injection, of powdered aloes,--five grains; hot water one-half pint." This is sufficient for two injections and should be used at about blood heat. [ANIMAL PARASITES 47] 2. Pin worms, Pink Root for.--"Take one ounce pink root, and one pint of water. Make a decoction of this by boiling the above to half a pint. Give a teaspoonful three times a day for two days, following this up by a good dose of castor oil or cream of tartar to thoroughly cleanse the system." 3. Pin worms, Quassia chips for.--"I knew of a child who had not slept three hours a night for several months, and several doctors had been called and none of them seemed to get down to the real trouble. Finally the mother tried an injection made by steeping quassia chips for two or three hours slowly, then straining it and injecting about one pint (luke warm) once a day. This gave the child immediate relief and improvement could be seen within a week." 4. Pin worms, Lime-water injection for.--"A very simple remedy is an injection of a teacupful of lime water once a day, preferably in the morning, as the worms are usually lodged in the rectum and this injection will bring them away, giving the child relief at once." 5. Worms-Stomach, Salt Remedy for.--"Encourage the child to eat as much salt as possible and give an injection of salt and water, about one teaspoonful of salt to two quarts of water, once a day."
