The blood flowing in our veins and arteries is living tissue. Nearly half of it consists of red blood cells which carry oxygen to the tissues. Approximately one trillion new blood cells are formed in the bone marrow daily. The raw materials required in the production of these cells are iron, proteins, and vitamins, especially folic acid and B12.
The red coloring matter, called hemoglobin is a protein which is composed of an organic iron-compound called "heme". The globin is a sulfur bearing protein which makes up 96% of the molecule. The formation of hemoglobin thus depends on adequate dietary supplies of iron and protein. Red cells have a lifespan of approximately 120 days and are destroyed and replaced daily. Each person should have 100% hemoglobin or about 15 grams to 100 cc of blood, and a blood count of five million red cells per millimeter. A drop in the hemoglobin content results in anemia and a consequent decreased ability of the blood to carry oxygen to the tissues.
Other causes can be intestinal parasites or worms. Hookworm, pinworms, roundworms and tapeworms feed on the blood supply as well as on the vitamins. Twenty-five hookworms can consume fifteen grams of blood every 24 hours; a tapeworm can cause an acute shortage of vitamin B12. Symptoms of intestinal worms are itching at the rectum, restlessness at night with bad dreams, diarrhea, foul breath, dark circles under the eyes and a constant desire for food. Garlic can help get rid of some types of intestinal parasites. Fresh papaya and grated raw carrot are also effective. After successful treatment for intestinal worms, perfect cleanliness should be observed to prevent recurrence.
