“…Philodendron poisonings in cats suffering from nervous symptoms—increased excitability, twitching and convulsions, encephalitis, and temporary (acute) kidney damage/failure—have also been described. Philodendrons, Epipremnum and Scindapsus have also been identified as allergenic (due to the presence of alkenyl-resorcinol derivates) [ 5 , 6 , 7 , 8 , 9 , 10 , 11 ].…”

Cases of ingestion of indoor poisonous plants are relatively common among animals and lead to both acute cases of poisoning and long-term exposure to harmful substances and chronic damage to the animal’s health. Plants produce a large number of secondary metabolites, which serve to protect the plant from attacks by insects, parasitic plants, fungi or, for example, during reproduction. However, these metabolites can be toxic if ingested by animals or humans. Toxicologically effective components found in plants are mainly alkaloids, glycosides, saponins, terpenes and others. This review article describes in detail the most common and popular indoor poisonous plants grown in Europe, the mechanisms of action of their active substances and clinical signs of the respective poisonings. This manuscript is supplemented with rich photographic documentation of these plants not found in similar articles, and also includes a description of the treatment of individual types of poisoning.

“…Many aspects of the biology of Anthurium species have been investigated, including taxonomy, chemistry (AQUINO et al, 2001), ecology and anatomy (LORENZO et al, 2010;POLI et al, 2012). Nevertheless, to the best of our knowledge, toxicological aspects of Anthurium remain mostly unknown (TWARDOWSCHY et al, 2007). Some species of this genus have been used in traditional medicine for over a century in the tropical parts of the Americas and the West Indies for the treatment of different diseases (JOLY et al, 1987;ZAMORA-MARTÍNEZ;POLA, 1992), some of them associated with immunostimulant activity.…”

Among other taxa of Araceae, the genus Anthurium is the largest of the family and one of the most important taxa. Some species of this genus have been used as a condiment, and its plants as ornaments and medicines for over a century. Anthurium maricense is an endemic species from "restingas" of Rio de Janeiro, Brazil, and it is used as ornamental and medicinal plant. This paper aimed an anatomical and toxicological study of its vegetative organs. A. maricense has subterraneous rhizome, adventitious roots and complete leaves. The anatomical features of vegetative organs are similar to other species of Araceae and genus Anthurium, especially the velamen in roots and calcium oxalate crystals in all organs. Under scanning electron microscopy (SEM), longitudinal grooves were observed in the raphides. For toxicological analyses, whole (with crystals) and centrifuged (free from crystals) fractions of the juices of each organ were administered via mouthwash and plantar inoculation to groups of five mice. The formation of edema was observed at 1, 3, 6, 24 and 96 hours and 7, 14, 21 and 28 days. The oral inoculations presented negative results for all groups, without edema. The plantar inoculations showed differing results: with centrifuged juices, mild edema formed but regressed; with whole juices, some animals presented severe edema. Our results indicated distribution and morphology of raphides and diverse chemical substances were related to the edematogenic process. A. maricense may potentially induce more chronic edema if compared to other species of Araceae.
