For California residents, the recent heavy rains resulted in a bumper crop of poison oak, a plant that poses a serious threat, especially to those who are allergic. Poison oak (Toxicodendron diversilobum) is commonly found in the western regions of the state, growing from sea level to the mountains. Grassy hillsides, forests, recreation areas, and coastal locations are home to the plant.
According to Dr. Rais Vohra, Medical Director for the Fresno/Madera Division of California Poison Control System (CPCS), poison oak can cause a rash about one to six days after exposure that itches and then forms water blisters. While many people believe the fluid from these blisters transmits poison oak, that is not the case. Exposure to poison oak can occur not only by touching the plant but also by touching clothing, shoes, gloves, pets, and tools. Even smoke from burning plants can cause irritation.
CPCS recommends the following tips to prevent poison oak exposure:
- Wear boots, gloves, and long pants when hiking.
- Stay on trails away from the brush where poison oak plants grow.
- Wash all clothing, tools, and pets that have been exposed to the plant.
- If you are exposed to poison oak, wash the area thoroughly with lukewarm water and apply rubbing alcohol to wash away the oil from the plant.
- Calamine lotion or hydrocortisone cream can help stop the itching, as can antihistamines.
- Do not scratch the rash as that can cause infection.
- Get immediate medical attention if you have trouble breathing or swallowing; the rash covers much of your body; you have many blisters; or swelling occurs, especially of the eyelids, face, or genitals.
