The ascorbic acid (vitamin C) is a fundamental part of metabolism. The majority of animals fulfill their vitamin C needs by autonomous synthesis. Humans are unable performing that because of a rare genetic error, and are dependent on daily intake from foods.
Vitamin C deficiency leads to the scurvy; in order of preventing the terminal stage of this lethal disease, Recommended Daily Allowance was set, that represent merely a near-minimum survival daily amount. The optimal daily intake promoting good health is higher then generally recognized. During period of stress or illness, the demand for vitamin C increases by several grades. The body indicates the higher need by substantial increase of bowel tolerance to high doses of vitamin C.
The overall tolerance of the body is extremely high and no known case of toxic over-dosage is ever known. Vitamin C is necessary for our immunity function. Almost all types of cancer are caused by very weak immune system and vitamin C deficiency. There was a case of patient who had scurvy-low levels of vitamin C even after 92 days of taking it in 17 g a day! Patients with cancer are usually tired, lethargic, they have low appetite, zero pain tolerance, bad sleep, bruise easily and those might be the signs of scurvy that are not recognized by health care providers.
Cytotoxic chemotherapy is based on the assumption that the substance is toxic to cancer cells and not to healthy ones. However, at conventional chemotherapy the damage to healthy cells can be substantial. We would need such resource that would have a much greater distance.
Perhaps the most extensive research on the aspect of vitamin C as a cancer treatment made Dr. Hugh D. Riordan, founder of Olive W. Garvey Center for Healing Arts (also called Riordan Clinic in Wichita, KS). He characterized the work in the center by these words: "We do not cure cancer, we treat people who have experienced cancer." In the Center for New medicine in Irvine, California they also use vitamin C as a natural way of chemotherapy.
Vitamin C is essential to healthy teeth, gums and bones (necessary for collagen production, a substance that forms the structure of bone and cartilage, and muscle and vascular tissue). It applies in the healing of wounds, scars and fractures. It helps fight infection, preventing and treating colds. It strengthens blood vessels. It improves the absorption of iron, calcium and folic acid in the body. It is an excellent remedy for allergies, has no side effects and can even prevent from asthma attacks. It increases resistance to cold, protects against heavy metal stress.
It can bind certain pollutants, it removes them from the cycle of drugs and the body eliminate them. Cigarette smoke contains a high proportion of heavy metals. One of these toxic metals is lead. Vitamin C can bind the lead and facilitate its elimination. The absence of vitamin C leads to damage of blood capillaries in place cell lining, damaged tooth bed, bleeding gums and poor wound healing. It also shows an increased fatigue, weakness, pain in bones and shriveled skin.
