What
poisonous plants look like and where they
are found
Symptoms
- Itching
- Red streaks or lines where the plant
brushed against the skin
- Small bumps
- Large, oozing blisters
Cause
- An irritating, oily sap called urushiol
triggers an allergic reaction once it comes into contact with
the skin.
- A person can be exposed to urushiol
directly or by touching objects that have come into contact
with the sap of one of the plants.
Prevention
- Learn to identify plants to avoid contact.
- Carefully remove plants from around
your home.
- Cover skin with clothing (long-sleeves,
long pants, socks and shoes) when walking in wooded areas.
- Be aware of resins carried by pets.
- OTC products
Treatment
- Immediately wash areas of skin that may have touched the
plant.
- Apply wet compresses or soak the area in cool water.
- OTC products (Hydrocortisone 0.5% or 1%)
- For a moderate or severe rash, visit your health professional.
Prescription treatment may be necessary.
