Substances, plants and mushrooms

The list contains the most frequently asked about and most common causes of poisoning in humans. You can search for items by typing in a search word. If you do not find the item you are looking for, you may call the Poison Information Center 0800 147 111 to check if it is poisonous.

Plant and mushroom species and genera are listed depending on whether all species of a genus are poisonous or only some. Unfortunately, the Poison Information Center is not able to identify plants and mushrooms over the phone. Identification should always take place on the spot.

In addition to books on mushroom identification, mushroom experts can help you identify mushrooms. Experts can be found via mycological societies and the Martha Organization, for example.
