Abstract
Tithonia diversifolia has manifold ethnomedicinal uses in traditional settings
without much consideration about the possible adverse effects of the consumption of its
crude extracts. In this study, effects of repeated oral administration of aqueous extract of
Tithonia diversifolia leaves (100 and 200 mg/Kg body weight) for seven days on
concentrations of serum electrolytes and biomolecules and the activities of alkaline
phosphatase, alanine aminotransferase and aspartate aminotransferase in serum, heart,
liver and kidney of rats were investigated. The extract significantly increased concentrations of serum calcium ion, potasium ion and HDL-cholesterol but reduced serum albumin concentration at both doses administered compared to controls. At 200 mg/Kg body weight, the extract significantly increased alkaline phosphatase activities in the liver and heart …
