What inside plants can make your hands itch?

Certain indoor plants, such as poinsettias, poison ivy, and some varieties of fig (like the rubber plant), can cause skin irritation or allergic reactions, leading to itchiness. The latex or sap they produce may contain compounds that trigger dermatitis in sensitive individuals. Additionally, plants like the peace lily can cause mild irritation due to their calcium oxalate crystals. Always wash your hands after handling these plants to minimize any potential irritation.
