A methanol extract of Indigofera suffruticosa aerial parts (1.25–7.5 mg/plate) showed mutagenic activity in a Salmonella microsome assay [97]. Furthermore, 8 plant species from 8 botanical families were assessed using in vivo assays (Table 3). Some aspects that influence the toxicity of medicinal plants reported in this study are: (a) time of exposure, (b) misidentification of medicinal plants, and (c) adulteration of medicinal plants. There are many dangerous contact-poisonous plants throughout the world, especially in the tropics.
