Studysummary In this study, high-dose oral administration of Ramania leaf ethanol extract in Wistar rats resulted in no significant acute toxicity symptoms, though gastric ulcers and hair loss were observed. The extract is classified as non-toxic under specified guidelines, with an LD50 greater than 5000 mg/kg. Our plain-language summary of this paper — not a Tressless recommendation.
The study tested the acute oral toxicity of ethanol extract from Ramania leaves (Bouea macrophylla Griffith.) on female Wistar rats using a fixed dose method. Four groups of 5 rats each were given doses of 50, 300, 2000, and 5000 mg/kgBW. Over 14 days, no deaths or significant changes in clinical conditions, such as diarrhea or changes in motor activity, were observed, although hair loss occurred. Body weight changes were not significant except in one group after 14 days. The extract was classified as non-toxic with an LD50 > 5000 mg/kg, but high doses caused gastric ulcers.
