Yes, poison sumac is generally considered worse (more toxic) than poison ivy, capable of causing more severe skin reactions, though both contain the same allergenic oil, urushiol, and the severity depends on individual sensitivity; however, poison sumac is much rarer and grows in specific wet areas, unlike the more common poison ivy.
Poison sumac is considered the “most toxic plant in the country.” However, on a positive note, it's also much rarer than the others.
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.

1. Water. Aquagenic urticaria is a rare condition that causes itchy and painful hives to break out whenever the sufferer comes into contact with water. These hives occur as a result of the body's mast cells releasing histamine, which creates the hives.
