How Does Activated Charcoal Work?

If you’re looking for a natural remedy that can help with a variety of health concerns, you may have heard about activated charcoal.

This black powder is made by heating carbon-rich materials, such as coconut shells, at high temperatures to create a highly porous substance that can trap toxins and chemicals. But how does activated charcoal work, and what are its benefits?

Activated charcoal is known for its ability to adsorb (not absorb) toxins and chemicals, meaning that it binds to them on a molecular level and prevents them from being absorbed by your body.

When you ingest activated charcoal, it moves through your digestive system, attracting toxins and chemicals along the way. These substances stick to the surface of the charcoal, which your body then eliminates through bowel movements.

But activated charcoal isn’t just used for detoxification. It’s also used in a variety of other applications, such as water filtration, air purification, and even teeth whitening.

In this article, we’ll explore the science behind how activated charcoal works and how it can benefit your health and well-being.

How Does Activated Charcoal Work?

If you’re wondering how activated charcoal works, you’re not alone. Activated charcoal is a form of carbon that has been treated with oxygen to make it highly porous.

This treatment creates millions of tiny pores between the carbon atoms, increasing the surface area of the charcoal and making it highly adsorbent.


Activated charcoal works through a process called adsorption, which is the binding of molecules or particles to a surface.

The tiny pores in activated charcoal provide a large surface area for adsorption to occur, allowing the charcoal to effectively trap and remove toxins, chemicals, and other impurities from the body.

Pore Structure

The pore structure of activated charcoal is what makes it so effective at adsorbing a wide range of substances.

The pores in activated charcoal can range in size from a few nanometers to several micrometers, allowing the charcoal to adsorb molecules of different sizes and shapes.

The pore structure of activated charcoal can also be tailored to specific applications. For example, activated charcoal used in gas masks has larger pores to adsorb larger molecules, while activated charcoal used in water filtration has smaller pores to adsorb smaller molecules.

Medical Uses

Activated charcoal has a long history of medical use and is commonly used in emergency situations to treat drug overdoses and poisonings.

When ingested, activated charcoal can adsorb toxins in the digestive system before they are absorbed into the bloodstream, reducing their harmful effects on the body.

Activated charcoal is also used in wound dressings, where it can adsorb bacteria and other harmful substances from the wound.

Additionally, activated charcoal is used in some skincare products to adsorb excess oil and impurities from the skin.

Overall, activated charcoal is a versatile and effective substance that works through adsorption to remove toxins and impurities from the body.

Benefits Of Activated Charcoal

Activated charcoal has been used for centuries for its medicinal properties. Here are some of the benefits of using activated charcoal:

Oral Health

Activated charcoal can help improve your oral health by removing toxins and bacteria from your mouth.

It can also help whiten your teeth by removing surface stains. Simply wet your toothbrush, dip it in activated charcoal powder, and brush your teeth for two minutes.

Rinse your mouth thoroughly with water and brush your teeth with regular toothpaste to remove any remaining charcoal residue.

Digestive Health

Activated charcoal can help improve your digestive health by reducing gas and bloating. It works by binding to gas-producing compounds in your digestive system and eliminating them from your body.

It can also help relieve symptoms of indigestion, such as heartburn and acid reflux. To use activated charcoal for digestive health, take it as a supplement or mix it into a drink.

Skin Care

Activated charcoal can help improve your skin by removing impurities and toxins from your pores. It can also help reduce the appearance of acne and improve your complexion.

To use activated charcoal for skin care, mix it with water to create a paste and apply it to your face. Leave it on for 10-15 minutes, then rinse it off with warm water.

Overall, activated charcoal has many benefits for your health and well-being. Whether you use it for oral health, digestive health, or skin care, it can help improve your overall quality of life.

Precautions And Side Effects

Interactions with Medications

Activated charcoal can interact with certain medications and reduce their effectiveness. If you are taking any medications, it is important to consult with your doctor before using activated charcoal. Some medications that can be affected by activated charcoal include:

  • Acetaminophen
  • Aspirin
  • Birth control pills
  • Phenobarbital
  • Theophylline

Potential Risks

While activated charcoal is generally considered safe, it can cause some side effects in certain individuals. These side effects can include:

  • Black stools
  • Black tongue
  • Vomiting or diarrhea
  • Constipation
  • In more serious cases, it can cause gastrointestinal blockages

It is important to note that activated charcoal should not be used as a supplement or taken on a regular basis without consulting with a healthcare provider.

Additionally, activated charcoal may not be effective for all types of poisoning, and other treatments may be necessary.

Key Points

Activated charcoal is a highly porous form of carbon that is used for a variety of purposes, including water filtration, emergency poison treatment, and skin care.

The porous structure of activated charcoal allows it to absorb toxins and impurities, making it an effective treatment for poisoning and drug overdoses when administered in a timely manner.

Activated charcoal is also used in skin care products to draw out impurities and toxins from the skin’s surface, leaving it looking and feeling cleaner and smoother.

While activated charcoal has many potential benefits, it is important to use it properly and only as directed. Always consult with a qualified healthcare provider before using activated charcoal for any purpose.
