Treatment for poisoning from plants and mushrooms focuses on symptomatic relief and, when possible, administering specific antidotes. For example, activated charcoal may be used to absorb toxins in the gastrointestinal tract if administered shortly after ingestion. Specific antidotes exist for some toxins; for instance, digoxin-specific antibody fragments can be used for cardiac glycoside poisoning. Supportive care, including hydration and monitoring of vital signs, is crucial.
