- Before buying a plant, have the store label it with both the common and scientific name.
- Show grandparents and baby sitters where the plant label is. It is very hard for poison specialists to identify plants from a description given on the phone. Know the names of your plants before a poisoning happens.
- If you have small children or curious pets, consider removing toxic plants from your garden and house. House plants should be placed out of reach of the very young.
- Teach children not to put any part of a plant in the mouth. This means leaves, stems, bark, seeds, nuts, berries, and bulbs. Do not allow children to suck nectar from flowers or make "tea" from the leaves. Never chew, or let children chew, on jewelry made from seeds or beans.
Handling Toxic Plants
Store labeled bulbs and seeds safely away from children, pets, and food-storage areas. Avoid confusing bulbs with edible onions.
Use protective gloves and clothing when handling plants that may be irritating to the skin. Wash clothes afterwards.
Discard plant leaves and flowers in a safe way so that children and pets cannot get to them.
Smoke from fires made of twigs and other parts of poisonous plants, including poison oak, can irritate or harm the eyes, throat, and other parts of the body.
- Do not eat plants or mushrooms collected outdoors unless you are certain they are safe.
Treatment for Exposures
What to do for a plant poisoning
If the victim is choking and cannot breathe, call 9-1-1
Treatment for Exposure:
- Mouth: Remove any parts of the plant or mushroom from the patient's mouth and clean out the mouth.
- Skin: Wash the area exposed to the plant with soap and cool water as soon as possible.
- Eyes: Flush eyes with lukewarm water for 10 to 15 minutes. Be very gentle, as vigorous or prolonged rinsing can hurt the eyes.
Meanwhile, call the Poison Control Center: (800) 222-1222
If you are advised to go to an emergency room, take the plant or a part of it with you (take more than a single leaf or berry). Take the label, too, if you have it. The correct name can result in the proper treatment if the plant is poisonous. If the plant is not dangerous, knowing the name can prevent needless treatment and worry.
Poisonous Plants for Humans
- Major Toxicity: These plants may cause serious illness or death. If ingested, immediately call the Poison Control Center -- (800) 222-1222 -- or your doctor.
- Minor Toxicity: Ingestion of these plants may cause minor illnesses such as vomiting or diarrhea. If ingested, call the Poison Control Center or your doctor.
- Oxalates: The juice or sap of these plants contains oxalate crystals. These needle-shaped crystals can irritate the skin, mouth, tongue, and throat, resulting in throat swelling, breathing difficulties, burning pain, and stomach upset. Call the Poison Control Center or your doctor if any of these symptoms appear following ingestion of plants.
- Dermatitis: The juice, sap, or thorns of these plants may cause a skin rash or irritation. Wash the affected area of skin with soap and water as soon as possible after contact. The rashes may be very serious and painful. Call the Poison Control Center or your doctor if symptoms appear following contact with the plants.
