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.

Cutleaf coneflower, Goldenglow (Rudbeckia laciniata)

Plants

The plant is non-toxic.

Cyanoacrylate glue

Substances

Keywords: super glue, instant adhesive glue

It is almost impossible to swallow cyanoacrylate glue. The adhesive solidifies and adheres to the inside of the mouth. No special treatment is usually required, because saliva will lift the adhesive in 12 to 48 hours. It is possible to accelerate this by gently brushing the insides of the mouth with a soft toothbrush.

Adhesive attached to the skin can be removed by using a brush, warm water and soap: Immerse the glued areas in warm soapy water and peel gently apart. Do not try to rip or tear the skin apart by force.

Rinse eyes thoroughly for at least 15 minutes. If the eyelids are stuck, apply a wet gauze patch, for example, over the eyes. Do not try to force the eyes open. If adhesive is attached to the retina, it will usually dissociate in a couple of hours. Have a physician or eye specialist check the eyes to ensure there is no damage.​
