Toxic Plants in Florida
All eight of these common plants contain urushiol, a plant oil that can cause a severe skin rash or allergic reaction when contact is made with any part of the plant or oil. Even smoke from burning these plants contains oil particles that can be inhaled and cause lung irritation. If exposed, immediately cleanse exposed skin, tools, shoes, or other items, with warm, soapy water and then rinse thoroughly with fresh, cool water. Clothes should also be washed thoroughly and separately from other laundry.
Symptoms appear within 8-48 hours and can last for weeks. Itching and burning of the skin may be followed by a rash, redness, swelling, and watery blisters. The rash, once properly cleaned, can last 2-5 weeks, but is not contagious and will not spread.
