INTRODUCTION
Activated 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)

4.
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)

5.
OBJECTIVE
 To discuss the uses and mode of action of activated
charcoal.

6.
USES OF ACTIVATED CHARCOAL
TREATMENT OF AILMENTS SUCH AS
•LIVER CANCER
•HEART BURN stomach acid and irritating sub from food
•PEPTIC ULCER(stomach acid(gastrin) )
•DENTAL INFECTION
 TREATMENT OF WOUNDS (INJURY)

7.
ANTIDOTE AGAINST;
• POISON (PLANT TOXINS)
• DRUG OVERDOSE (ASPIRIN,PARACETAMOL, COCAINE)
• BEE STING
• SNAKE BITE (VENOM)
WATER PURIFICATION

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

11.
MECHANISM OF ABSORPTION
Most 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)

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 CHARCOAL
Activated 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)

18.
CONCLUSION
 Activated charcoal is an old natural remedy of medical
proof.

19.
RECOMMENDATION
I join the pediatrician to recommend that every household
should have some activated charcoal in their chest for first
aid measure
