There is an intense search for new plant-derived medicines to match the ever increasing prevalence of drug resistance. Toxicity profiles of three commonly used plants against helminthosis in Uganda will support their optimum use.
Objective: To evaluate the sub-acute toxicity of aqueous leaf extracts of Tephrosia vogelii (TV), Vernonia amygdalina (VA) and Senna occidentalis (SO).
Methods: One hundred Wistar white albino rats in 10 groups were dosed orally daily with 200, 400 and 600 mg/kg of TV, VA and SO for 28 days or Goodwin’s physiological solution. Daily changes in behaviour, feed/water intake and weight (weekly) were monitored. On day 29, blood for haematology, serum for biochemical analysis and organs (lungs, liver, kidney, heart and small intestines) for histopathology were collected... View More»
