POISON IVY, OAK & SUMAC
What every parent should know this summer 🌿
The rash is NOT contagious.
The rash is NOT spreading.
The real culprit is an oily plant resin called urushiol.
HOW TO IDENTIFY THEM:
🌿 Poison Ivy
• "Leaves of three, let it be"
• Most common in the Eastern U.S.
• Can grow as a vine, shrub, or ground cover
🌿 Poison Oak
• Usually has 3 leaves
• Leaves resemble oak leaves
🌿 Poison Sumac
• 7–13 leaflets
• Found in wet, swampy areas
• Often considered the most potent of the three
MYTHS PARENTS OFTEN BELIEVE:
❌ The rash spreads from scratching
❌ Blister fluid spreads the rash
❌ The rash is contagious
✅ New spots often appear days later because different areas absorb urushiol at different rates.
THE RASH MAY KEEP COMING BACK IF...
Urushiol is still hiding on:
👟 Shoes
🎒 Backpacks
🥎 Sports equipment
🧤 Gardening gloves
🐶 Pet fur
👕 Clothing
Many "new exposures" are actually old oil left behind.
AFTER EXPOSURE:
✔ Wash exposed skin ASAP with soap and cool water
✔ Wash under fingernails
✔ Clean clothing, shoes, and gear
✔ Bathe pets that may have been exposed
✔ Avoid touching eyes, nose, or mouth before washing
The sooner urushiol is removed, the better.
NATURAL WAYS TO SOOTHE ITCHING:
🌾 Oatmeal baths
🧊 Cool compresses
🌿 Aloe vera
🌼 Calendula
🌱 Jewelweed
🌸 Chamomile
💧 Witch hazel
Parent Tip:
Store aloe gel, witch hazel, or jewelweed preparations in the refrigerator for extra itch relief.
