Contact with any part of the poison oak plant can cause an intensely itchy, blistering rash. Washing immediately with water and a mild soap or apply rubbing alcohol may help lessen symptoms.
According to the American Academy of Dermatology Association (AAD), all parts of the poison oak plant — the leaves, stems, flowers, roots, and vines — contain urushiol.
If a person touches the plant or comes into contact with the oil in some way, it can trigger the body’s immune system and produce a rash.
Between 80–90% of people will develop a rash when they come into contact with 50 micrograms of urushiol. This amounts to fewer than one grain of table salt.
A person can come into contact with the oil via touching the plant or anything that has come into contact with it, such as pets, tools, or clothing. If someone is burning the plant nearby, a person can also inhale the oil.
This article discusses what a poison oak rash looks like. It also looks at the treatment options available, how to identify poison oak, and how a person can help prevent the rash.
People can develop an allergy to the oil, leading to a rash referred to as allergic contact dermatitis.
People who are allergic to the oil do not have a reaction until they come into contact with it for a second time. The immune system learns to recognize the oil from the first contact and then reacts to it aggressively on future contact.
The rash appears where the oil has come into contact with the skin.
The AAD notes that a person can expect the following:
•An intense itch at the area where the rash will appear.
•An itchy, blistering rash that appears shortly after the itching begins.
If a person thinks they have come into contact with poison oak, they should:
•Wash the skin immediately using:
•dishwashing soap
•laundry detergent
•poison oak cleanser
•rubbing alcohol
According to the AAD, there are several reasons a poison oak rash may appear to spread.
One reason is that there is a short window of time where a person may be able to accidentally spread the oil from one part of their body to another. This can cause a rash to develop near the original rash, giving the appearance that it is spreading.
Alternatively, the oil can spread from a person’s clothes onto their skin, causing a rash to appear on parts of the body that did not touch the plant.
In addition, the rash will develop first on the area of skin that has the most oil on it. Skin exposed to less oil may react later on.
Ways that a person can help prevent the spread of the oil include:
•wearing protective gloves when removing clothes that may have come into contact with the oils
The rash is not contagious. But it is possible to spread the oil to others. Urushiol will often stick to clothing, garden tools, and other items that have come into contact with the poison oak.
A person may also come into contact with the oil when touching an animal’s fur if it has been near the plant.
Recognizing the actual plant is challenging because individual poison oaks come in different forms. The FDA states that it grows in the Eastern and Southern United States.
Poison oak is a low shrub with fuzzy green leaves that appear in clusters of three. The edges may have rounded tips or pointed tips. Berries that are yellowy-white in color may also be present.
To help a poison oak rash from developing, a person should:
•Wear clothing that covers the skin, such as long sleeves, boots, socks, and gloves.
•Apply an ivy blocker to the skin.
•After being outside:
•machine-wash any clothing
•clean any tools using rubbing alcohol or soap with water
People whose work puts them at a higher risk of contact with poison oak oil need to take measures to protect themselves. Employers must also help.
The NIOSH has tips for workers who come into contact with poisonous plants.
These include suggestions such as:
•wearing long sleeves, long pants, boots, and gloves to ensure that as little skin as possible is exposed
•washing any clothes exposed to poisonous plants in hot water, with detergent, and not with any other clothes
•using barrier creams where necessary to protect the skin
Any swelling beyond small hives in the affected area indicates that a person should contact a doctor.
The FDA recommends people contact a doctor about their rash if they experience:
•a temperature over 100ºF
•pus or yellow scabs on the rash
•tenderness around the rash
•itching that causes people to wake up or worsens at night
Other causes of rashes that may look similar to poison oak rash include:
•Other plants: Poison ivy and poison sumac also release urushiol when they become damaged, bruised, or burned.
•Ringworm: This occurs due to a fungus that feeds on keratin, which is a protein in the skin. It causes itchy skin and a ring-shaped rash on the body. Unlike poison oak, it is contagious.
•Psoriasis: This is an autoimmune condition that may cause a person to experience a rash, which can vary depending on the type of psoriasis a person has.
