Poinsettias are popular holiday decorations that could cause trouble for people who are allergic to latex or rubber, says Dr. Bassett, because the plant is a relative of the rubber tree. About 3 million Americans are thought to have a latex allergy, according to the American Latex Allergy Association.

Allergic reactions can be caused even without direct contact, if a pet rubs up against poinsettia and bumps into someone with an allergy, Bassett adds.
