ABSTRACT
Malaria

and the burden of this disease is getting worse, mainly due to the increasing
resistance of plasmodium falciparum against the widely available anti malaria
agents Herbal medicine for  the treatment
of various disease including malaria are an important part of the cultural
diversity and tradition of which Ikere-Ekiti biodiversity has been an integral
part. Two major anti malaria drugs widely used today came originally from
indigenous medical system that is quinine and atemisin in respectively. Malaria
infection is the second largest killer disease after HIV IN Nigeria failure of
the orthodox medication due to drug adulteration high cost of procurement of
anti malaria drugs and in the use of high dosage of the new anti malaria drug combination
thereby has timed the attention of the people in the world towards the used of
local herbs this study investigated selected medicinal plants used in treatment
of malaria in Ikere Local Government Area, Ekiti State and how the treatment (
selected plant) are very efficient and active in treatment of malaria. Malaria
is one of the most common major health problem all over the world.
Pharmacothropy is the most common treatment strategy for the disease. But the
main obstacle behind this is emergence of resistance for many of these drugs.
Hence, to overcome this problem, the major often available since the ancient
times is medicinal plants all over the world. Mankind is blessed with wide
range of herbal plants for various ailments with lot of those useful for
malaria treatment also. In the review we have highlighted many of those plants

INTRODUCTION
          Malaria is the world’s most important
parasite disease especially when plasmodium falciparum is the causative agent.
Malaria is endemic in about 100 developing countries, and kill an estimated 1.2
million people each year in Africa (WHO 2001). In Nigeria and some West
African, one in five children will die before they are five and 75% of those
death are attributed to malaria (NWAKA 2006). Pregnant woman and children under
five years of age are the most vulnerable. The socio economic consequences of these
diseases are particularly dramatic in rural areas where poverty and malnutrition’s
are more pronounced. In the absence of an effective vaccine, the fight against
malaria depends on chemotherapy and the reduction and prevention of human anopheles
mosquito contacts through the use of insecticides treated bed nets and environmental
care.
          In Nigeria, a large number of plant
species have been identified as anti malaria. Pure products have been isolated
from same of these plant amongst which are those whose anti-malaria activities
are resistant stains of  P. falciparum.
It is therefore imperative that anti malaria drug development has to be pursued
further with those highly active product to perianal, manufacture and
distribution and then final marketing phamarcovigilance. We report on the
plants which have been identified as anti malaria and the work done so far in
evaluating their anti-malaria potential the review is structured according to
plant families and the extent of investigation carried out in the specific
plant families to date some of these selected plant used in treatment of

malaria followed by sub acute and chronic toxicity tests.
