Whether or not you're an outdoorsy type of person, learning about the plants around you can prove extremely important. Whether you're hiking, camping, having a picnic, or playing in the yard with your kids, knowing which plants to stay away may just save your life. Some of the most toxic plants are often the prettiest. And several common plants can actually be highly toxic. This list might surprise you! (1)
Which common plants are also highly toxic?
1. Buttercups
As a kid, did you ever use this common plant to see who liked butter? Maybe you didn't know that some varieties are highly toxic. Buttercups tend to grow in damp spots. There are several different species, and many of them are poisonous. Buttercups contain caustic sap that can leave blisters on your skin if you come in contact with it. The poisonous sap also provokes coughing. If it gets into your eyes, it can cause temporary blindness. (2)
2. Cowbane or Water Hemlock
Everyone knows that Superman's bane is kryptonite. Cowbane, so aptly named, is violently toxic to cattle and pets alike. Also called Water Hemlock, this common plant grows in wet places like on riverbanks. And it's known as one of the most highly toxic plants on Earth. If you come in contact with it, symptoms can include nausea, seizures, and even death. (3)3. Elder
The most common types of elder are red elder and black elder. If you've been taking elderberry syrup to fight a cold or the flu, you may be wondering why elder is on this list. While ripe black elderberries are safe to eat, every other part of the plant is toxic. Wash your hands immediately after touching an elder plant. Symptoms include headache, weakness, abdominal pains, and occasionally seizures. (4)
4. Oleander
Oleander is often used in landscaping thanks to its beautiful pink and white flowers. And it's also grown as a houseplant! While pretty to look at, all parts of the plant are toxic, even the flowers. Unfortunately, oleander contains highly toxic compounds, including cardiac glycosides, that have the ability to alter your heart rate and cause nausea, headache, weakness, and even death. (5)5. Hogweed
Hogweed is a plant that contains poisonous sap. While the flower of Giant Hogweed resembles Queen Anne's Lace, the similarities end there. Queen Anne's Lace grows 2-4 feet tall, but Giant Hogweed grows 8-14 feet tall. Similar to Hemlock, the highly toxic sap of Giant Hogweed can cause severe skin and eye irritation, along with painful blistering, permanent scarring, and even blindness. If you come into contact with this plant, immediately wash the area with soap and water, and keep the area away from sunlight for 48 hours. (6)
6. Rhubarb
Strawberry - Rhubarb Pie. Have you every had any? It's a fresh treat in springtime when strawberries and rhubarb are in season. But only use rhubarb stems. Why? Well, you may not know that the leaves and the root of the rhubarb plant are highly toxic. They contain oxalic acid and oxalates, which can cause burning in the throat and eyes, nausea, diarrhea, and at higher levels even kidney stones. (7)7. Castor Bean
Wait - I thought castor oil was good for me. Yes, that's true. When castor beans are used to make castor oil, the heat treatment destroys all the toxins. But castor beans on their own are deadly. The hull of the bean contains ricin and ricinine, compounds that destroy body tissues and can lead to death. Purchase high quality castor oil, but if you want to grow your own, be careful of the seeds. (8)
