THE POISONOUS GARDEN: THE CHEMISTRY BEHIND THE INTOXICATION BY DOMESTIC ORNAMENTAL PLANTS. In times of the COVID-19 pandemic, despite the fact families have spent more time together, the job demands and commitments that adults have now brought into their homes may mean their attention has been taken away from their children. This, combined with the absence of older family members or domestic helpers that assist in looking after the children has left them potentially more exposed to domestic accidents. Data from the National Toxic-Pharmacological Information System indicate that two-thirds of domestic intoxications with plants (usually the ornamental ones) occur in children. These accidents can be caused either by inhalation, contact with the skin, eyes and mucous membranes, as well as by ingestion. The toxicity of ornamental plants is due to the presence of substances such as oxalic acid and its highly irritating salts, alkaloids, glycosides, flavonoids, and toxic terpenes, among several other classes of secondary metabolites. In the present study, we carried out a survey of the main ornamental plants used in the country and analyzed the toxic substances that can cause numerous conditions from dermatitis in milder cases to death in more severe cases.
