Poison oak is a plant that is identified by three leaves. In most cases the middle leaf is the longest. It can grow as a vine or a shrub. In some areas the plant may have yellow or green flowers and clusters of green-yellow or white berries. The appearance of this plant varies depending on the area it is growing in. Contact your local state information center to identify what poison oak looks like in your area. If you are allergic to this plant and your skin comes into contact with it, you may have a reaction and develop symptoms. A quick response to this reaction will help to minimize symptoms and prevent complications.
Initial Symptoms
You can be exposed to poison oak by directly touching a plant, touching an object such as clothing that rubbed up against a plant, or your skin can be exposed if the plant is burned and releases chemicals into the air. According to the University of California, within a few days of coming into contact with the leaves or stem, your skin may begin to itch and develop watery blisters. The blisters may or may not leak. In most people, this reaction lasts no more then 10 days. However, with every exposure you become even more sensitive to the plant.
Additional Signs
The American Academy of Dermatology states that after contact with poison oak, if you are allergic, you will develop streak marks on the area of your skin that made contact. The area may turn red and become swollen. The academy claim that the rash does not spread. Instead over a period of days, the areas of your body that actually came into contact with the plant will slowly develop symptoms. According to the National Institutes of Health, symptoms are usually worse 4 to 7 days after exposure. However, it may take up to three weeks for the symptoms to completely subside.
Severe Symptoms
The Centers for Disease Control and Prevention recommend to be on the lookout for severe allergic reactions. If the plants are burned, you may inhale irritants, which can cause lung inflammation. Get immediate medical attention for symptoms such as trouble breathing, extreme swelling, severe itching that does not respond to medication, a rash on your face, lips, eyes, or genitals or if there is a yellowish or smelly discharge from the blisters.
