Did anyone look into activated charcoal to help detoxify the body?
Here is an article that describes the detoxification and medicinal properties of activated charcoal:_http://www.quantumbalancing.com/news/charcoal_poultice.htm
Activated Charcoal Universal Antidote and Detoxifier
Richard C. Kaufman, Ph.D.
Activated charcoal is a highly absorbent gritty black material commonly found in air and water filters. Activated charcoal is created by carbonizing organic matter in a kiln under anaerobic conditions and activating the material with oxidizing gases like steam or air at high temperatures. This oxidative process erodes the charcoals internal surfaces and increases its adsorption capacity by creating an internal network of very fine pores. Usually bone char, coconut shells, peat, coal, petroleum coke, and sawdust are the starting materials for making activated charcoal.
Early Uses Of Charcoal
The medical uses for charcoal date back to the Egyptian Papyrus of 1550 B.C. During the time of Hippocrates (400 B.C.) physicians treated epilepsy and anthrax with charcoal. In the 1700s charcoal was often prescribed for bilious problems (excessive bile excretion). After the development of the charcoal activation process (1870 to 1920), many reports appeared in medical journals about activated charcoal as an antidote for poisons and a cure for intestinal disorders.
Contemporary Charcoal Use
Modern research has validated most of the early uses for charcoal and discovered exciting new applications. This article will discuss the many important therapeutic uses for activated charcoal;(1,6)
* Universal antidote for drugs, chemicals and poisons.
* Systemic clearance of drugs and intoxicants.
* General detoxification.
* Anti-aging and life extension.
* Reducing cholesterol, coronary disease and arteriosclerosis.
* Counteracting pathogens.
* Intestinal complaints.
Antidote For Drugs, Chemicals and Poisons
Activated charcoal has the well-earned reputation of being a universal antidote. It can adsorb most organic chemicals, many inorganic chemicals and countless poisonous substances before they can cause harm. How well activated charcoal really works in practical situations depends on several different factors:(8)
* The type of toxicant (its chemical structure and physical properties)
* The amount and type of charcoal ingested.
* The length of time from toxin ingestion to activated charcoal ingestion.
* The contents of your intestinal fluids and intestinal transport efficiency.
As a general rule, a single large dose of activated charcoal should be taken as soon as possible after ingesting a poison. The amount of activated charcoal should exceed the toxic substance by a factor of eight (a ratio of 8:1). In other words, if youre poisoned with 5 grams of a chemical, you need to take at least 40 grams of activated charcoal. Other researchers recommend different dosages. Some experts believe a 10 to 1 ratio is correct. Still other experts recommend a fixed amount of 50 to 100 grams. I recommend ingesting a minimum of 50 grams of activated charcoal as a counterpoison, because ingesting large amounts of activated charcoal is harmless, and taking too little is ineffective. Besides, how often in the case of an emergency can you precisely determine the amount of the poison?
The actual effectiveness of the activated charcoal will vary, so take more than you think you require. Activated charcoal should be taken within 30 minutes of ingesting the poison. The longer the delay, the less effective activated charcoal will be. On some poisons delaying more than 30 minutes decreases the effectiveness of the activated charcoal as an antidote by up to 60%. The bottom line is plain and simple. Keeping activated charcoal in your medicine cabinet and taking it if you are poisoned could save your life and your money too. It has been estimated that use of activated charcoal for treating poisonings could reduce the stay in intensive care from 3 or 4 days to one, saving over $100,000,000 in health care costs and preventing unnecessary disability and death.(11)
Systemic Clearance of Drugs and Intoxicants
Nowadays, activated charcoal is often used to clear drugs and intoxicants that can enter the body through the intestinal tract, and even by injection and other routes. The systemic clearance of toxic substances or detoxification by activated charcoal is accomplished by taking multiple daily doses. Activated charcoal detoxifies the body in several manners:(4)
Purifies the 6-8 liters of digestive fluids that are secreted daily which in turn helps remove foreign substances from the blood.
Absorbs the intoxicant substance and its metabolites that are excreted into the small intestine from the biliary (bile) tract, preventing their reabsorption.
Absorbs drugs that diffuse back into the stomach and intestines.
Decreases the detoxification work load of the liver.
Activated charcoal shortens the time it takes an intoxicant to leave the system and decreases the duration and intensity of symptoms.(15) People who take activated charcoal after drinking alcohol or taking recreational drugs such as cocaine or amphetamines recover quicker. I recommend activated charcoal as part of a drug recovery program to ease withdrawal symptoms and reduce drug craving. Other nutrients that help are the neurotransmitter precursors L-Tyrosine, L-Tryptophan, L-Phenylalanine, Choline and DMAE (Dimethylaminoethanol).
Even experts disagree on the best way of using multiple doses of activated charcoal to remove intoxicants. Most protocols are based on experience with drug overdosages. In actual clinical situations, the activated charcoal regimen is optimized to the patient. The doctor considers the type of toxic substance, severity of intoxification, digestive functions and electrolyte balance. For mild overdoses and intoxification, I suggest up to 80-100 grams divided into 4-6 daily doses of powdered activated charcoal until the symptoms are eliminated. Consult an expert who can optimize your regimen. For a dangerous overdosage call your physician or hospital imwww.ely.
Very few health practitioners realize that activated charcoal is the best single supplement for enhancing detoxification. Detoxification is an on-going biological process that prevents toxins (from infectious agents, food, air, water, and substances that contact the skin) from destroying health. Chronic exposure to toxins produces cellular damage, diverse diseases, allergic like reactions, compromised immunity and premature aging.(14)
To use activated charcoal in a detoxification plan, I recommend about 20 grams a day of powdered activated charcoal be taken in divided daily doses for several months or the duration of the detoxification program.
In addition to activated charcoal, the ideal detoxification prescription includes sauna baths, exercise, a special diet, and supplements (unsaturated fatty acids, vitamin C, niacin, proteolytic (protein digesting) enzymes, liver support phytonutrients and a comprehensive multiple nutrient formula.(9)
Anti-Aging and Life Extension Dr. V. V. Frolkis, a famous Russian Gerontologist, and his colleagues have discovered that activated charcoal is a potent life-extending agent. Activated charcoal has been found to increase the mean lifespan of older test animals by approximately 40% and their maximum lifespan by approximately 34%.(2)
Activated charcoal decreases the age-related increase in the brains sensitivity to drugs and toxins.
Activated charcoal normalizes cholesterol and lipid metabolism.
The regular use of activated charcoal improves the adaptive functioning of essential organs (the liver, kidneys, and adrenals). That translates into better defense mechanisms.
Microscopic tissue analysis shows that activated charcoal prevents many cellular changes associated with aging-decreased protein synthesis, lower RNA activity, arteriosclerosis, and organ fibrosis. So the cumulative effects from activated charcoal are longer life and improved overall health.(19)
A recommended protocol for anti-aging and life extension benefits is as follows: On two consecutive days each week, take about 30 grams each day of powdered activated charcoal in divided daily doses. Take charcoal in the morning, at midday and before bed on an empty stomach. Avoid excessive calories or unhealthy foods on those days.
Reducing Cholesterol and Coronary Artery Disease You can help your heart and circulatory system by taking activated charcoal. Activated charcoal lowers the concentration of total lipids, cholesterol, and triglycerides in the blood serum, liver, heart and brain. In one study that was reported in the British journal, Lancet, on patients with high cholesterol, 8 gm of activated charcoal taken three times a day lowered total cholesterol 25%, lowered LDL cholesterol 41% and doubled their HDL/LDL (high-density lipoprotein/low-density lipoprotein) cholesterol ratio. Microscopic tissue examination studies have shown that a daily dose of activated charcoal may prevent sclerotic changes in the heart and coronary blood vessels. To help your heart and blood vessels, I suggest the following: 12-17 grams of activated charcoal twice a day for one month under the guidance of a physician who can measure cardiovascular improvements and cholesterol levels.(5,15)
Activated charcoal reduces the activity of some viruses. So if you catch a cold or the flu, try activated charcoal. You may suffer less and heal faster. Activated charcoal also prevents the poisonous activity of many harmful bacteria in the human body by adsorbing the toxins and enzymes that they generate. Studies have shown that activated charcoal is an effective treatment for dysentery, cholera, and many infectious conditions of the digestive tract.(16,17)
Activated charcoal can be an effective adjunct to any regimen for the treatment of systemic Candida albicans infections. Activated charcoal adsorbs much of the toxins that Candida produces that otherwise would be absorbed by the blood and carried throughout the body. These toxins produce pathological changes in tissues and organs and interfere with proper immune function. Candida toxins cause allergic reactions and are responsible for the debilitating symptoms of Candidiasis.
Activated charcoal also suppresses the growth of intestinal-based yeasts.(3) Activated charcoal counteracts the Herxheimer reaction--a severe, short-term exacerbation of Candida symptoms caused by the copious amount of toxins produced by dying yeast cells. The Herxheimer reaction is often so unpleasant that patients abandon treatment before completion. Activated charcoal is one method for alleviating the symptoms of yeast die-off so people can continue their treatment and not suffer.
I suggest 20-30 grams of powdered activated charcoal a day in divided dosages on an empty stomach until the problem is eliminated. The larger amount is taken for more severe situations. Again, a reminder: do not take required medications within 2 hours of taking activated charcoal.
Activated charcoal has been used by physicians since the last century to treat various intestinal complaints. Abdominal distension (bloating) and flatulence respond favorably to treatment with activated charcoal. Diarrhea caused by food poisoning, bacteria, nervousness and other factors is usually alleviated by taking activated charcoal.(10) Some physicians have used activated charcoal to stop bleeding from ulcerative colitis and calm spastic colons.(12) Activated charcoal is the best intestinal deodorant available. Taking activated charcoal counteracts decomposition products from food (such as beans) that cause flatulence and diarrhea. Individuals with malodorous stools should reach for activated charcoal. Travelers to foreign countries would be wise to pack activated charcoal. In my opinion, activated charcoal is the most practical way to effectively counteract food poisoning. To alleviate intestinal disorders with activated charcoal, I recommend the following. As an antidote for food poisoning, take 20 grams of activated charcoal two to three times daily. For other intestinal complaints, 5 to 10 grams of powdered activated charcoal twice daily.
Charcoal Is Safe
Toxicology studies have proven that activated charcoal is basically harmless. Ingesting high dosages does not interfere with sleep, appetite or well being--or cause major problems. There are several undesirable effects of using activated charcoal that can be avoided by complying with the following directions. Activated charcoal is highly adsorbent; when it is ingested at the same time as medication, supplements and foods it may decrease their absorption and utilization. Therefore, always allow 2 hours before and wait 2 hours after using activated charcoal to eat, take supplements or swallow medication. Activated charcoal has a natural tendency to cause constipation. That can be counteracted by taking a mild herbal laxative with the activated charcoal. Finally activated charcoal harmlessly blackens your stools. Although black-gray stools look strange, they can be used to calculate your bowel transit time. Just measure the length of time from taking activated charcoal to the appearance of darkened stools.
Not All Charcoal is Alike
Numerous companies manufacture activated charcoals, each of which can have different adsorptive capacities. Different source materials and manufacturing procedures give each brand of activated charcoal its own pore diameters and internal volume that determine its adsorption capacity. The U.S.P. (United States Pharmacopoeia) standard for activated charcoal specifies an internal surface area of 1000 m2/g (square meters per gram). Recently, several companies have begun manufacturing Super activated charcoals, with up to 3 times the internal surface area per gram and far greater adsorption power than standard activated charcoal.(3)
Powders, Capsules, or Tablets? Because of the large volume of charcoal that is needed, it is easiest to take liquid preparation of charcoal powder. For example, to take 30 grams of charcoal a day in capsules would require that you swallow about 60 capsules. Furthermore, activated charcoal tablets are not effective. They take too long to disintegrate and release the activated charcoal.
Ideal Charcoal Preparation - (see VRPs EnteraKlenz)
Unfortunately, a simple water and charcoal mixture is unpalatable and messy. It tastes like a charcoal briquette, and blackens your teeth, gums and tongue. These problems can be avoided by ingesting a powdered activated charcoal complex that contains a thickening agent like bentonite, with added flavors and mild sweeteners.
Research studies showed that that the addition of bentonite significantly improved the palatability of an activated charcoal and water slurry. Bentonite acts as thickening agent that reduces powdery mouth-feel and improves the taste without reducing the efficacy of activated charcoal. In fact, bentonite is an enterosorption agent and a poison antidote in its own right. For example, bentonite has been shown to bind and reduce the poison paraquat. The addition of chocolate further enhances the palatability of activated charcoal in research studies and practical experience.(12,13)

The above link also explains how to make a poultice from it (a paste of activated charcoal + water + flaxseed to help keep it together I guess on a paper towel and taped to the area of the liver or wherever you want to apply it). But I don't know how effective such a thing would be, more research is needed for this, but also for the benefits of taking it orally - which according to the above article seem to be pretty darn good.
Here's a link that lists more uses of charcoal, many of which seem safe to try to test its effectiveness:_http://www.betterthangreens.com/Catalog_208.html
Charcoal and its Effectiveness
INJURY There was a lady who had injury underneath her eyes after falling. Her whole head was painful and her cheeks were swollen. After applying a hot charcoal poultice, her pain and swelling subsided. A boy fell on a rock and injured his knee severely. He was taken to the doctor but there was no improvement of his injury. He was given hot and cold treatment twice a day followed with a charcoal poultice. A few weeks later, his swelling was gone and his health returned again.
FEVER Don't use ice on the head when fever is present. Use cold water instead. Use hot poultice over the abdomen area. Place a charcoal poultice and heat on the abdomen and drink charcoal mixed with water. It's more effective to use hot water than cold ice.
INFECTION OF THE EYES AND EARS When the eye gets red due to infection, apply poultice. If the eye feels better with a hot poultice, apply hot charcoal poultice. Otherwise, use a cold charcoal poultice. For ear infection, apply charcoal poultice externally over the infected ear.
INDIGESTION, DIARRHEA, GAS, STOMACH ULCER, ULCERATIVE COLITIS, BED-RIDDEN PATIENTS Mix 1-2 teaspoonful of charcoal powder with a cup of water and drink using straw or take 2 capsules or 4 tablets 3-4 times a day. Take charcoal powder and olive oil mixture for indigestion to cleanse the stomach and bring healing. Take 1-2 teaspoons of charcoal and mix with 1,000cc of water and let the charcoal settle. Use the water for charcoal sensitive children, ulcer patients and people suffering constipation instead of water for the most effective results.
HALITOSIS (BAD BREATH) Brush teeth with charcoal powder or hold charcoal tablet in the mouth. Avoid overeating and snacking. Use charcoal tablet in the mouth or rub charcoal powder on the infected area for infection or sore.
SNAKE OR SPIDER BITE Mix charcoal powder with olive oil or flaxseed powder and water. Put over the bite to relieve pain and adsorb poison. Use a charcoal poultice as soon as possible. In case of snake bite, change the poultice every 10-15 minutes and take 10 tablets or 2-3 tablespoons of charcoal. If the pain continues, place ice bag over the bite and continuously injestcharcoal.
INFLAMMATION AND INFECTION Activated charcoal adsorbs bacteria, virus, bacterial poison, hormone, tissue fluid, and pus to prevent swelling and infection from external wounds, bacteria, poison, and allergies. Renowned leader of preventive medicine Ellen G. White wrote, "When the patient was agonizing due to pain and indicated that he was dying, I recommended charcoal poultice. I have suggested use of charcoal and the patient was able to fall into deep sleep and was healed. I prescribed this treatment to the students who had infection due to injury on the hand. Infection was removed; pain was relieved and was quickly healed. I think you might laugh at this but if I could give this treatment a strange name and use it then it would be effective to a well-known doctor."
INFANT JAUNDICE An infant had a high bilirubin level was given charcoal water (1/2 teaspoon mixed with a cup of water) every 2-3 hours. It's more effective to feed charcoal water when the infant is 4 hours than 12 hours. Feed charcoal water to infant until baby can't drink anymore. Remove all clothing and sunbath baby 1 hour per day.
SORE MOUTH, THROAT AND TONSILLITIS Rub charcoal powder inside the mouth. Use charcoal powder to brush teeth. Mouth will be blackened but the healing will be faster because charcoal will cleanse the mouth. In some cases, sleep with the charcoal tablet. Soar throat is healed also with the same method. Use the same method for tonsillitis and apply charcoal poultice for faster recovery.
SPRAIN Few months ago, my mom called, asking what she should do for ankle sprain. I told her to place the ankle in the hot water for 3 minutes and the cold water for 30 seconds and keep going from hot water to cold water for 15-20 minutes. Then make a charcoal poultice to place over her sprained ankle. After that regimen, she became a missionary because she has experienced the effectiveness of charcoal.
BEE STING I was stung on the cheek; my friend on the palm, my neighbor was stung on the right eyelid, and another person on his leg. All of us used charcoal poultice over and were able to experience relief.
GASOLINE, PETROLEUM, LIGHTER GAS Intake large amount of charcoal to adsorb these toxins.
DAMAGED LIVER Charcoal adsorbs poisons from the bloodstream which stops the spreading of poison caused by damaged liver. Take large dose of charcoal to prevent blood from getting poisoned.
IMPROPER METABOLISM Six adult kidney failure patients were given activated charcoal for 4-8 weeks. Their triglyceride level was decreased by 67%. The patients experience itchiness due to chronic kidney failure can benefit from taking charcoal.
INGESTED POISONOUS MUSHROOM A person who ingested poisonous mushrooms within the past 24 hours can be effectively treated by charcoal. An unconcious patient should be administered charcoal by the gastrointestinal method.
PAIN Abdominal pain, pain from sore throat, sprain, arthritis, pleurisy, and any other pain can be relieved by charcoal poultice. It only takes 10 minutes to subdue pain.
SYMPTOMS FROM OVER USING TYLENOL, ASPIRIN Take charcoal. As soon as poisonous substance was taken, take charcoal (twice as much as the poisonous substance) mixed in water. Continue to take charcoal (8-10 times more than the poisonous substance).
ANEMIA AND PAIN DUE TO CANCER Anemia due to poison caused by cancer can be treated with charcoal. The hemolytic poison can be adsorbed by charcoal and pain in other parts of the body can be relieved by charcoal poultice. The dog that had cancer was treated with charcoal poultice, was cured of cancer whereas the mouse didn't have such a great result.
POISON IVY Take 8 tablets, 4 capsules or take 2 tablespoons of powdered charcoal 2 times a day, everyday and take charcoal bath (add charcoal to bath water). Use charcoal poultice on the area affected.
PROPERTIES OF CHARCOAL
Because charcoal can pack molecules of ammonia gas into its crevices, it can attract and hold 80 quarts of ammonia gas per one quart of pulverized charcoal! This process is called adsorption, or attaching onto rather than taking inside, as in absorption.
In 1733, Scheele made an experiment with charcoal in which a gas was trapped in an inverted tube with charcoal, the lower end of the tube being submerged in a container of mercury. As the gas was adsorbed by the charcoal, a vacuum appeared in the tube and sucked the mercury up into the tube.
Pharmacist P.F. Touery, in 1831, making a demonstration of the effectiveness of charcoal before the French Academy of Medicine, survived after swallowing 15 grams of strychnine (ten times the lethal dose) and an equal amount of charcoal --about three tablespoonfuls.
Charred toast and other scorched food in the kitchen are fats, carbohydrates, and mineral salts, the very parts burned away in charcoal, leaving only charred cellulose.
The skeletal structure remaining in true charcoal is inert, where as the remaining substances in charred food can react unhealthfully with the body, and even act as cancer-producing agents.
The activation process was not invented until after the turn of the 20th century, but charcoal was already recognized as a useful healing agent even though only regular charcoal was then in use.
Following activation of charcoal with pressurized steam or strong acid, the surface area of one cubic centimeter is 1,000 square meters!
This expanded surface is due to the fact that charcoal particles have thousands of crevices, pits, grooves, and holes which, when opened out, make quite a large surface area.
USE OF CHARCOAL
When Do You Use Charcoal?
Charcoal is used for internal and external infection and poisoning. Cases of injury, fever, eye and ear infection, gastritis, internal disorders, halitosis, poisonous spider or insect bites, bee sting or snake bite, any inflammation, colitis, indigestion, cellulites, diarrhea, gas, jaundice, and ingestion of gasoline, petroleum, lighter oil can be benefited.
How Much Charcoal Do You Take?
Charcoal comes in powder, capsule, and tablet form. For a normal adult, 1 tablespoon of powder, 3-4 tablets, or 2-3 capsules can be taken. Take 2-3 times a day.
Reference: There is a theory that if you take charcoal regularly for a long time, bodily nutrients can become insufficient. We don't recommend taking charcoal regularly over a year but up to 12 weeks, there seems to be no problem. If you take charcoal powder, make sure mix it with water, otherwise, charcoal powder can enter into
Different Charcoal Usage:
Gastric disorder, colitis, liver disorder and other internal disorders: mix honey 200 gram (7 oz.), olive oil 200 gram(7 oz.), charcoal 300 gram (1.5 cup), eucalyptus oil 5 drops then take 1-2 spoonfuls morning and night.
For tonsillitis, infection in abdomen, and sore throat: use a charcoal poultice for hot and cold treatment. Ingest 1-2 tablespoons of charcoal.
The wikipedia article mentions some of those uses as well:_http://en.wikipedia.org/wiki/Activated_carbon
What I do know is that it is used in water and air filtration systems (like in a fishtank). Many sources also claim that activated charcoal is probably the best known odor eliminator in a room. Just put fist-sized pouch somewhere in a stinky room and within a day or so or that stink should be gone and it should last for a few months before needing replacement or re-activation. It is also used to keep fridges and freezers fresh and odor-free, which is good to prevent odor contamination where odor from food influences how other food smells and tastes. There is a cute little product that uses activated charcoal called "Fridge It" that is like a purple cube that you can hang in your fridge.
Apparently it is an even better odor absorber than baking soda, which is traditionally known to be a good one. The advantage of baking soda is you can use it directly on fabrics and carpets to suck up all the bad smells out of them (including smelly cars), just sprinkle a thin layer on the fabric and leave overnight and vacuum the next day and voila.
Also, it seems white vinegar is in a similar league with baking soda for being great odor eliminator and simultaneously a multi-purpose cleaning agent just like baking soda. It seems to me that if you have some activated carbon (charcoal), baking soda, and white vinegar, you can basically totally avoid practically all chemical cleaning products.
A bunch of uses for baking soda, some being medicinal too like for rashes, burns, and insect bites:_http://lifehackery.com/2008/07/22/home-4/
A bunch of uses for white vinegar (I think apple cider vinegar would work too but that one is way more smelly):_http://www.vinegartips.com/
Those 3 items which apparently are completely non-toxic and edible have so many uses it makes me wonder why anyone would ever need expensive and harmful chemicals in the house.
