Yes, Devil's Ivy (Pothos) is mildly toxic to humans if ingested, containing calcium oxalate crystals that cause immediate burning, swelling of the mouth/throat, and irritation; the sap can also cause skin irritation, so keep it away from kids and pets, though it's rarely fatal.
Aside from eating the leaves, the sap from the leaves and stems can cause a skin rash. Generally, good first aid can help prevent this from happening. Most exposures to Devil's Ivy involve only a small amount of the plant.
The most common toxic indoor plants are dieffenbachia (Dumb Cane), philodendron (Philodendron), and aloe vera (Aloe Vera). These plants contain a chemical called calcium oxalate raphides or “raphides,” which can cause mouth, throat, nose, eyes, and skin irritation in humans.
Many people are allergic to English ivy. Touching its sap alone can cause contact or allergic contact dermatitis, which is a very itchy—and uncomfortable—rash. Contact with English ivy can also cause swelling and shortness of breath.
Poison hemlock can really impact humans, 100x worse than poison ivy. In fact, exposure can be lethal under certain circumstances (ingestion for example). Don't be panicked if you see white flowers, not all of them are poison hemlock. Look for those purple splotches on the stem, immediate giveaway.
Tobacco (Nicotiana tabucum)
Undoubtedly the most deadly plant on the planet, tobacco has managed to enslave humankind into farming it across nearly 10 million acres around the world, despite it killing over 8 million people every year – 1.3 million of whom die from second-hand smoke.
Don't touch these plants!
This is false. Poison ivy (and other poison plant rashes) cannot be spread from person-to-person after the rash develops. Only contact with the oil urushiol, from the plant's sap, can cause the poison ivy rash.
To Tell Poison Ivy Apart, Look for These Features
Luckily, that familiar rhyme “Leaves of three: let it be” holds true: all of its leaves have three separate leaflets (unless some have been eaten). However, many harmless species also have clusters of three leaflets, so remember: The central leaflet has a longer stalk.
However, if traces of urushiol linger on your sheets or pajamas, they can indeed transfer to your skin and cause new rashes. Think of urushiol as a sneaky ninja, hiding in plain sight. If not washed away properly, it might just find a way back onto your skin during a peaceful night's sleep.
