Plant and shrub poisoning

[Ernesto]

A few commonly grown plants are poisonous. Generally, poisoning is unlikely unless large quantities are ingested (for example, if the leaves and other components are concentrated into a paste or brewed into a tea) or the plant is highly toxic. Highly toxic and potentially fatal plants include castor beans, jequirity beans, poison hemlock, and water hemlock, as well as oleander and foxglove, which contain digitalis glycosides. Few plant poisonings can be cured by specific antidotes. (See also Overview of Poisoning.)
Many other plants cause less serious toxic effects (see table Moderately Poisonous Plants).
