What is poison oak?

Poison oak is an infamous plant that is found in sets of three. Its green leaves are reminiscent of an oak tree and have ragged edges, as opposed to the pointed leaves of poison ivy. It causes a red, uncomfortable and itchy rash known as allergic contact dermatitis, and it’s found in most places in the country.

Like its “sister” shrub poison ivy, poison oak has the ingredient urushiol. This is an oil found in the plant’s leaves, stems, and roots, and is what causes the itching when it comes in contact with the skin. Not only does it stick to the skin, it’s also transferrable from clothing and gardening tools. Since the rash is spread through the oil, you can only catch it by touching the oil itself and not the blister or rash that it causes.

Once you are exposed to urushiol, you become allergic to it, meaning you will be more sensitive and your body can react worse to it in the future.

These plants are of the same botanical family, but it’s important to differentiate between them so you know what you are dealing with.

Western poison oak is the most common type of poison oak and mostly grows along the Pacific coast. It can either be a small shrub or a climbing vine.

Atlantic poison oak is more common in the southeast parts of the country, but is still a lot less common than western poison oak.

Examine the plant you suspect to be poison oak. Look at the plant closely to identify it, but never close enough to come in contact with the “poison” urushiol. Remember not to touch the plant unless you have protective gear that you can dispose of afterwards.

Check the leaves. Both types of poison oak have ragged or wavy edges, and both grow in sets of threes. Poison oak leaves are usually green in color, but they can also be yellowish, brownish, or reddish, depending on the season. Their top side has a more “glossy” appearance than the underside, which is velvetier.

Look at their stems. The stems of poison oak are greyish green and are covered in tiny hair-like structures.
