Abstract
To assess the safety of oral compound honeysuckle moisturizing Chinese herbal extract for eczema treatment, Sprague-Dawley (SD) rats were oral administered three doses (20.8, 41.6, and 83.3 g/kg, based on raw materials) of the extract daily for 13 consecutive weeks. The study aimed to identify potential toxic reactions, mortality due to accumulation, and recovery after discontinuation. By observing these factors, we sought to determine the target organs of toxicity and establish nontoxic doses for SD rats. The results indicated that during the administration period and subsequent recovery period, there were no significant abnormalities in weight gain, food intake, hematology, blood biochemistry, or urine indicators. Additionally, histopathological analysis of major organs (heart, liver, lungs, kidneys, spleen, and brain) revealed no significant extract-related lesions. Moreover, no significant local toxic lesions were observed in the oral buccal and tongue mucosa. Finally, under the experimental conditions of this study, the preliminary nontoxic response dose of oral gavage compound honeysuckle moisturizing Chinese herbal extract administered to SD rats for 13 weeks was 83.3 g/kg/day (calculated as raw medicine).
期刊介绍:
Drug and Chemical Toxicology publishes full-length research papers, review articles and short communications that encompass a broad spectrum of toxicological data surrounding risk assessment and harmful exposure. Manuscripts are considered according to their relevance to the journal.
Topics include both descriptive and mechanics research that illustrates the risk assessment implications of exposure to toxic agents. Examples of suitable topics include toxicological studies, which are structural examinations on the effects of dose, metabolism, and statistical or mechanism-based approaches to risk assessment. New findings and methods, along with safety evaluations, are also acceptable. Special issues may be reserved to publish symposium summaries, reviews in toxicology, and overviews of the practical interpretation and application of toxicological data.
