Article Synopsis
- The study investigates the toxic effects of Schefflera barteri, a plant used in Cameroon for various treatments, due to misconceptions about the safety of herbal medicines.
- Methods included preparing the plant extract, conducting phytochemical analysis, and performing acute and sub-acute toxicity tests on mice and rats to evaluate health impacts.
- Results indicated that while the extract has a high LD50 (greater than 16,000 mg/kg), it led to significant changes in certain blood parameters and showed liver damage in histopathological analysis, highlighting potential risks associated with its use.
Pteleopsis hylodendron (Combretaceae) is used in Cameroon and West Africa folk medicine for the treatment of various microbial infections (measles, chickenpox, and sexually transmitted diseases). The antibacterial properties of the methanolic extract and fractions from stem bark of Pteleopsis hylodendron were tested against three Gram-positive bacteria and eight Gram-negative bacteria using Agar-well diffusion and Broth microdilution methods. Antioxidant activities of the crude extract and fractions were investigated by DPPH radical scavenging activity and β-carotene-linoleic acid assays.

Methodology: The antimicrobial activities of plant extracts were evaluated against clinically proved beta-lactam-resistant bacteria (Klebsiella pneumoniae, Klebsiella oxytoca, Enterobacter cloacae, Serratia marcescens, Acinetobacter baumannii, Staphylococcus aureus and Enterococcus sp.) and reference strains of bacteria (Escherichia coli ATCC 35218, Enterobacter aerogenes ATCC 29751, E.
