Background: Although cetrimonium bromide is widely used for its bactericidal effects, the safety of cetrimonium bromide remains controversial. Therefore, the phytotoxicity of cetrimonium bromide was tested to evaluate its acute toxicity to plants and possible toxicity to other organisms and the ecosystem. Results: The germination rates of two test species, Lactuca sativa and Brassica campestris...
BORON (B) is a micronutrient element that plants require in trace amounts.The concentration range in which plants exhibit neither deficiency nor toxicity symptoms is narrower for B than for any other nutrient element. Plants can experience both B deficiency and B toxicity in a single growing season (Reisenauer et al., 1973). In humid regions, rainfall can cause excessive leaching of B, and fert...
Toxicity of phytochemicals, plant-based extracts and dietary supplements, and medicinal plants in general, is of medical importance and must be considered in phytotherapy and other plant uses. We show in this report how general database analyses can provide a quantitative assessment of research and evidence related to toxicity of medicinal plants or specific phytochemicals. As examples, several...
