Activated charcoal is an excellent detoxifier. It is one of the few substances that can absorb gas and so help uncomfortable bloating and wind… Learn more below.

Used historically in water filtration and for ulcers and wounds

Activated charcoal was first used medicinally by the ancient Egyptians in 1500BC on infected ulcers and wounds, and for unpleasant gases from the digestion. It was used by Hippocrates and Pliny (Ancient Greek physicians) for a huge range of diseases including epilepsy and anthrax. It was used to make water safe as far back as 450BC. Its ability to remove toxins from the air, water and the body, when ingested, continues to be its main use today (1).

Still used in hospital today to absorb poisons and drug overdoses

Activated charcoal is still one of the best treatments to help when given quickly for accidental poisoning (2) (consuming something toxic) and the first line of treatment in Emergency Departments but it is most effective when given within an hour of poisoning (3). This makes it a good choice for your home medicine cabinet (it has no taste so can be mixed with liquid and drunk) especially if you have young children.

Research shows activated charcoal is very safe

90 day high dose studies show no evidence of toxicity in bamboo source activated charcoal (4). It has been widely used for poisoning and toxicity for over 170 years and is generally considered safe for consumption (5). In the 1800’s it was popular to demonstrate the power of activated charcoal to medical students by taking it with the poison strychnine and showing it prevented any ill effects.

It can help relieve bloating and gas

Studies show that activated charcoal taken after a meal can effectively reduce wind (belching and flatus) (3) and may reduce feelings of bloating and stomach cramps (6). A study of 262 patients with IBS saw a significant improvement in symptoms when taking activated charcoal for 12 weeks (7).

May lower cholesterol (8)

Studies showed patients taking 4-32g/day of activated charcoal for 3 weeks saw a dose dependent improvement in their cholesterol levels with a reduction in LDL cholesterol (‘bad’ cholesterol) and an improvement in their ratio of HDL (good): to LDL (bad) cholesterol (8),(9).

May work as a natural teeth whitening agent

Although there are no large studies on Activated Charcoal use in dentistry there are many anecdotal and experiential reports of the benefit of activated charcoal on oral health and staining of the teeth, which is why it has become popular in toothpastes. Charcoal does not damage the enamel on the teeth, is very safe and its huge adsorption ability makes it a good choice for trying to remove staining on your teeth. Because it absorbs gas it is also great for bad breath. Although it is black it washes off easily and doesn’t stain.

Why not give it a try? Also consider teeth pulling with coconut oil which is a fantastic practice for a healthy mouth see here.

Use it to help nausea and diarrhoea from food poisoning

Activated charcoal has been shown to be effective and safe to use for diarrhoea from any cause making it a great choice for the home medicine cabinet (10) in case of an issue. Its ability to absorb toxins makes it a good choice if you think something has upset your stomach. It has also been shown to be effective against chemotherapy induced diarrhoea helping significantly improve symptoms (11).

Activated Charcoal can remove toxins from the body by trapping them on its surface

Activated charcoal works because it has a huge surface area which is charged to attract and trap toxins on its surface, binding them and effectively removing them from you.

Make sure it is made from a natural source like coconut or bamboo

Coconut shell is a wonderful, natural and eco-friendly source of activated charcoal. Coconuts can be harvested regularly, produce much less ash and they are easily renewable without damaging the environment. They make a superior activated charcoal to wood with better adsorption due to their smaller pores. It is important that you source your activated charcoal from a high quality source where it is pure with no toxins, heavy metals, fillers, genetic modifications or contaminants more commonly found in unregulated, cheap products.

Dr Jess says: Activated charcoal is a staple for your home medicine cabinet and a great, safe go-to remedy in our house for ‘upset stomachs’ or over-indulging! It is the only product I have seen significantly improve bloating in patients and is a great digestive remedy. I use toothpaste with charcoal in it and despite being grey I really think it helps keep my teeth white!

Activated charcoal has been used since Ancient Egyptian times to remove toxins and was even used as an early method of mummification to preserve bodies as it effectively prevented them decaying. It is a truly amazing substance but make sure you get it from a reputable source to avoid impurities.
