“Leaf of three, let it be”

How can I identify poison ivy?

Poison ivy is a “woody” vine common in wooded areas, known for its urushiol—a colorless oil present in its fruit, leaves, stem, roots, and sap. To identify it, remember these five characteristics:

• It has three leaflets on each leaf stem.

• The leaves are usually pointed at the tip, with the edges being smooth or slightly toothed, slightly red appearance in the spring, green in the summer, and yellow, orange, or red in the fall.

• It grows as a ground vine, climbing vine, or even as a shrub in some areas.

• It commonly grows in wooded areas, along roadsides, and along riverbanks. It can be found in most regions of the United States except for the far West, Alaska, and Hawaii.

• It produces small, white berries that persist through winter and can help in identifying the plant when leaves are not present.

What’s the best way to prevent contact?

Wear long pants, long-sleeved shirts, socks, and fully enclosed shoes when exploring these areas

What should I do if I was exposed to poison ivy?

Wash your skin promptly with cool, running water using an oil-based soap or a specific poison ivy cleanser like “Tecnu.” Cool water is crucial as warm or hot water can open pores, allowing toxins to penetrate the skin. Clean beneath fingernails with a toothbrush to remove any trapped oil, and discard the toothbrush afterwards. Urushiol can transfer to objects like clothing, prompting allergic reactions. Immediately remove and wash exposed clothing (separately from other garments) and any contaminated items.

How do symptoms show and what can I do about them?

Initial symptoms include colorless, mildly itchy “bubbles” on the skin. Avoid scratching to prevent spread and infection—tapping the area can alleviate itching without damaging the skin. Do not burst blisters. Bentonite clay is an effective treatment; apply it to the skin, let it dry for 15-30 minutes, then rinse with cold water. Applying calamine lotion four to six times daily and using ice packs can also soothe the affected area.
