INTRODUCTIONActivated charcoal is a dark grey residue consisting of carbon and ash obtained by slow pyrolysis. (Timber, 2012)
Activated charcoal is not the same as the regular charcoal. Activated charcoal is produced using steam or air at high temperature to oxidize charcoal in a controlled environment. (NHR, 2012)

Activated charcoal can adsorb thousands of its own weight in gases, toxic metals, poisons and other chemicals, thus making them ineffective or harmless. (Thrash et al, 1998)
Today, Activated charcoal has been recommended by the poison control centers of America, including the animal poison control center because of its high value as a universal antidote (Bradberry and Vale, 1995)

OBJECTIVE To discuss the uses and mode of action of
activated charcoal.

GENERAL CHARACTERISTICSLARGE SURFACE AREA
SMALL PORE SIZE
HIGH ADSORPTION ABILITY
Robert et al, 2012

PLATE 2: MECHANISM FOR ADSORTION IN ACTIVATED CHARCOAL (FRANCIS,2012)
Activated charcoal is subjected to steam and oxygen, small pores are created. This pores are active at trapping chemicals, especially those that are not attracted to water such as organic compound.
MODE OF ACTION OF ACTIVATED CHARCOAL
![Page 11: USES AND MODE OF ACTION AC](https://reader036.vdocuments.net/reader036/viewer/2022062412/588195c01a28ab0d358b67ad/html5/thumbnails/11.jpg)
MECHANISM OF ABSORPTIONMost xenobiotics are carbon based that
may adhere to carbon compounds by chemical forces.
By supplying a large area of carbon surrounding the xenobiotics, are attracted to the carbon and the xenobiotics bind at a number of sites, effectively sticking to the charcoal.
(American Academy of Clinical Toxicology, 1997)

SCHEMATIC DIAGRAM OF ACTIVATED CHARCOAL GI SYSTEM SHOWING XENOBIOTICS TRANSPORT SYSTEM
Hill Healthcare publication, 1987
When activated charcoal is taken orally, it is dispersed throughout the digestive system, as it passes naturally through the digestive system. Substance are bound to the particles of activated charcoal forming complex.
A large portion of the substance are adsorbed directly from the digestive system or blood vessel surrounding or supporting the digestive system, this process may occur by migration, secretion or diffusion.

SAFETY OF ACTIVATED CHARCOALActivated charcoal is simple to use and is a time-
tested natural remedy that has many valuable uses
It has no dangerous side effects or contraindications,
It is a very efficient cleaner of the body when taken orally and it also helps to purify the blood. (Kaufman, 2005)
It is an odourless, tasteless, flavourless, powder but it texture is less appealing. (Medical world news, 1967)

CONCLUSION Activated charcoal is an old natural remedy of
medical proof.
