ANTI RADIATION HERBS

 

Herbal Antioxidant Protection from Radiation

Introduction to antioxidants

An antioxidant is a molecule capable of slowing or preventing the oxidation of other molecules. Oxidation reactions can produce free radicals which start chain reactions that damage cells.  Antioxidants stop these chain reactions by removing free radicals and inhibit other oxidation reactions by being oxidized themselves. Although oxidation reactions are crucial for life, they can also be damaging. Specific plants, herbs and spices contain a variety of important antioxidants of which many are famous in Asian cooking where they play an important role in dietary health.

Insufficient levels of antioxidants or excessive oxidative stress may damage or kill human cells. Oxidative stress is an important factor in many human diseases. We now have a greater understanding of why certain plants are beneficial in supporting human health due to the potent antioxidant compounds they contain that help replenish our bodies own natural antioxidant defences.

Because they have one or more unpaired electrons, free radicals are highly unstable. They scavenge your body to grab or donate electrons, thereby damaging cells, proteins, and DNA (genetic material). It is impossible for us to avoid damage by free radicals as these arise from sources both inside and outside our bodies. Oxidants that develop from processes within our bodies form as a result of normal aerobic respiration, metabolism, and inflammation. Exogenous free radicals form from environmental factors such as excessive sunlight, strenuous exercise, X-rays, smoking and alcohol. Ever increasing environmental pollution generates additional free radical damage and toxicity overwhelming our already overburdened detoxification systems.

Antioxidant compound target different cellular reactions and cells of different organs and these are now believed to play a role in preventing the development of such chronic diseases as cancer, heart disease, stroke, alzheimer's, rheumatoid arthritis, diabetes, liver disease and cataracts.

Nuclear radiation and free radical damage

The recent concerns about radioactive isotopes being released into the environment as a result of the Fukushima Nuclear Power Plant reactor leakage has the potential to emit some of the most dangerous forms of free radical damage from ionizing radiation. Radioactive elements undergo decay and emit high-energy particles energetic enough to ionize atoms by knocking off their electrons. This ionizing radiation can damage DNA molecules directly, by breaking the bonds between atoms, or it can ionize water molecules and form free radicals (our cells are mostly water and ionizing radiation breaks H20 down into harmful free radicals H+ and OH-), which are highly reactive and also disrupt the bonds of surrounding molecules, including DNA. This DNA damage is enough to kill cells or cause them to mutate in ways that may eventually lead to cancer. The DNA damaging effects of radiation is measured in units called sieverts, which take into account the type and amount of radiation, and which parts of the body are exposed, allowing us to compare different kinds of exposures in one scale. In a typical year, a person might receive a total dose of two or three millisieverts from things like ambient radioactivity, plane flights and medical procedures. 100 millisieverts a year is the limit above which cancer risk starts to increase, according to the World Nuclear Association. The greatest danger is for people living in an affected area and winds can carry radioactive isotopes many hundreds of kilometers (as evidenced from the Chernobyl disaster in Europe), which can accumulate in the body, water table and food chain further damaging tissue over time and causing disease and cancer.

Effects of ionizing radiation

Free radical organ damage depends on which free radical is involved, how high concentration, the target of damage and predisposing factors. Ionizing radiation produces the most rapid free radical damage to various organs, and may produce immediate or delayed damage as follows;

• Brain: Nerve cells and brain blood vessels can die, leading to seizures.
• Eyes: Radiation exposure increases the risk of cataracts.
• Thyroid: The thyroid is very sensitive to the effects of Radioactive iodine (I-131) (in fact, I-131′s affinity for the thyroid is used therapeutically to specifically attract radiation to the thyroid in order to treat thyroid cancer and overactive thyroid). When a healthy thyroid is exposed to I-131, it can lead to decreased thyroid function and, over time, thyroid cancer.
• Lungs: When you breathe in invisible nuclear fallout particles, it can lead to lung cancer.
• Heart: High doses of radiation can damage the cells in the blood vessels that feed the heart, reducing cardiac function.
• Digestive tract: Sensitive cells in the intestinal lining can be damaged, leading to loss of appetite, nausea, bloody vomiting, and bloody diarrhea.
• Reproductive organs: Rapidly dividing cells (eggs and sperm) in the ovaries and testes can die, leading to sterility.
• Skin: Rapidly dividing skin cells can be damaged, leading to skin lesions and burn.
• Lymphatic organs: Rapidly dividing lymphatic cells die and damaged bone marrow may have trouble replenishing these immune-boosting cells, increasing the risk of infection.
• Other effects and symptoms of excessive free radical damage from radiation exposure includes: tumor growth / cancer, hemorrhages under the skin, bleeding from the nose, gums or mouth, anemia (low red blood cell count), hair loss, weakness and fatigue, fainting, dehydration and inflammation of tissues (swelling, redness or tenderness).
• Large radiation doses destroys millions of cells and tissues of the body and as such can lead to impairment of any organ function and / or death from organ failure.

Antioxidant protection from free radical damage

The therapeutic benefit of many medicinal plants is a direct result of their antioxidant properties on specific organs and bodily tissues. As such, herbals provide important protection from free radical damage and ionizing radiation. To assist detoxification from high doses of free radicals or radioactive isotopes then an understanding of plant antioxidants and their individual effects is very helpful in selecting the formulations that provide optimal antioxidant components to restore health.

The first step is always to remove oneself from the source of excessive free radicals or area of ionizing radiation exposure and to avoid consuming contaminated foodstuff or drinking contaminated water. Eat a diet high in uncontaminated fresh fruits and vegetables. Studies in Japan have shown a therapeutic effect from consuming a diet high in brown rice, miso soup, vegetables, onions and garlic and abundant seaweed, while also consuming plenty of antioxidant rich green tea. Any diet high in protective nutrients, enzymes and antioxidants will provide higher cellular protection.

Many antioxidant herbs have been studied for their effects as radioprotective agents (able to protect humans from ionizing radiation). In nature, plants have evolved an array of phytochemicals to protect them from the ionizing radiation from the sun and to survive in harsh environments. Tropical herbs and spices in particular have evolved as a response to the intense ultraviolet radiation around the equatorial regions. These herbs have been at the forefront of research into radioprotection as a result of their unique antioxidant effects. They hold immense promise to save human lives in the wake of the rise in global environmental pollution and the potential exposure to nuclear radiation, such as from the recent reactor accident in Fukushima, Japan.
