Pinworms, tapeworms and roundworms are parasites existing in the intestinal tract. The three most common types of worms found in the body are thread or seat worms, roundworms, and tapeworms. There are other, less-common parasites that enter the body, such as hookworms and those of unclean pork, which thrive upon various conditions of filth and degeneration. Some common symptoms are restlessness at night, picking the nose, gritting the teeth, itching at anus, dry cough. Worms sometimes cause spasms, fits or convulsions. Worms are the effect, not the cause. The cause is poor diet, poor hygiene and constipation. Worms are found when the stomach is deranged from eating improper foods. The lack of wholesome foods, heavy mucus and starchy food intake contribute to worms. To work on the effect and simply rid the body of worms without altering your diet is like kiling the flies and leaving the garbage - which has attracted them - in the same foul condition.
