Abstract

Anthocleista djalonensis A. Chev. (stem bark), Azadirachta indica A. Juss (stem bark and leaf), Cajanus cajan (L.) Huth. (leaf), Crescentia cujete L. (stem bark), Lawsonia inermis L. (leaf), Lophira alata Banks ex C.F. Gaertn. (stem bark), Myrianthus pruessii Engl. (leaf), Nauclea latifolia Sm. (stem bark), Olax subscorpioidea Oliv. (root), and Terminalia glaucescens Planch ex Benth. (stem bark and root) are combined for use in the treatment of malaria in Akure, Southwestern Nigeria. The powdered plant samples were screened for phytochemical constituents, proximate composition and mineral elements according to standard protocols. Plasmodium berghei infected mice were screened for parasitemia and administered with water and ethanol extracts of the combined plant sample. Toxicity and histopathological studies were carried out on the liver and kidney sections of the mice. Data were statistically analyzed. The powdered herbal recipe contained appreciable phytochemicals and important minerals. The concentrations administered for LD50 did not elicit adverse reactions in the experimental animals, and no mortality was recorded. Histological studies revealed some pathology caused by the malaria parasite, as well as side effects of the extracts administered. This is discussed in relation to safety considerations. Key words: Malaria, herbs, phytochemical, histopathology, Nigeria.

Highlights

  • An infectious disease caused by Plasmodium species, has been a menace to the health conditions of both rural and urban populations in Nigeria (NGA, 2005)

  • This study reports the anti-plasmodial activity of a polyherbal recipe and serves as a ground breaking report of such combination

  • Priyanka et al (2013) reported the antiplasmodial potentials demonstrated by A. indica in P. berghei infected mice model

Summary

Introduction

An infectious disease caused by Plasmodium species, has been a menace to the health conditions of both rural and urban populations in Nigeria (NGA, 2005). It is a global epidemic the incidence and severity are higher in the tropics especially in the subSaharan Africa, where pregnant women and children are the most susceptible (Nmorsi et al, 2007; WHO, 2008; Nguta et al, 2010; Akanbi et al, 2012).
