Genotoxicity detection of five medicinal plants in Nigeria. (1/1)
This study was performed to investigate the safety of Alchornea cordifolia, Cnestis ferruginea, Lonchocarpus sericeus, Trema orientalis, and Senna alata in respect to genotoxicity. These five medicinal plants are widely distributed in Africa. They are used as a traditional medicine in many African counties for the treatment of microbial, inflammatory, and stress-related diseases. To evaluate the bacterial reverse mutation of these five medicinal plants, the in vitro Ames test using Salmonella typhimurium TA98, TA100, TA1535, and TA1537, and Escherichia coli WP2uvrA, with or without the addition of S9 mixture was performed. Concentrations used for this test were 625, 2,500, and 5,000 microg per plate. A. cordifolia, C. ferruginea, L. sericeus, and T. orientalis showed negative results in the bacterial reverse mutation test, suggesting that it is potentially safe for these plants to be used in medicinal plants supplements at high doses. However, our experiments suggest that S. alata is a potent mutagen. Therefore, further studies are needed to evaluate the carcinogenicity of S. alata in order to adequately assess the risks for human health. (+info)'Trema' is a medical term used to describe an involuntary, rhythmic quivering or trembling movement of a body part, often associated with conditions such as multiple sclerosis, Parkinson's disease, or essential tremor.
"Trema" is not a term that has a widely accepted medical definition. It is a term used in anatomy to refer to a small opening or tremor, but it is not commonly used in clinical medicine or medical research. If you have encountered this term in a medical context and are unsure of its meaning, I would recommend checking the source material for more context or consulting with a healthcare professional.
