At The Art of Skin Dermatology, our dermatologists specialize in treating a variety of skin conditions, including allergic reactions and rashes caused by poisonous plants like poison ivy, poison oak, and poison sumac. If you suspect that you have come into contact with any of these plants, our experts can help you identify the best treatment option for your specific needs.
What is Poison Ivy ?
Poison ivy, poison oak, and poison sumac are all common toxic plants that can result in itchy skin rashes. These plants contain a substance called urushiol, which is an oily sap that triggers an allergic reaction when it comes into contact with the skin. Whether you touch the plants directly or handle objects that have been contaminated with their oil, you may develop a red and itchy rash known as allergic contact dermatitis.
If you are experiencing symptoms or have concerns about a potential exposure to these poisonous plants, we encourage you to schedule a consultation with our dermatology associates. During your appointment, we can provide a thorough evaluation and discuss the available skin treatments that can help alleviate your discomfort.

How Common Is A Poison Ivy Rash?
It is quite common for individuals to develop a rash when they come into contact with poison ivy, poison sumac, or poison oak. In fact, approximately 90 percent of people who encounter these plants experience an allergic reaction. What’s interesting is that even a tiny amount of urushiol, the oily substance found in these plants, can trigger a rash. In fact, an amount smaller than a grain of salt is enough to cause a reaction.
There are several ways in which patients can develop a rash from these poisonous plants. Direct contact with the leaves of the plant is one way, as the urushiol can easily transfer to the skin. Another way is by inadvertently touching urushiol and then touching other parts of the body, spreading the oil and causing a reaction. Inhaling smoke from a burnt poisonous plant can also lead to a rash. Lastly, coming into contact with an object that has urushiol on it can result in a rash as well.
If you suspect that you have been exposed to any of these poisonous plants or have developed a rash, it is important to seek medical attention. Our dermatologists at The Art of Skin Dermatology can help identify the best treatment option for your specific situation. Don’t hesitate to schedule a consultation with us to learn more about how we can assist you in managing your symptoms and finding relief.

What Do Poisonous Plants Look Like?
Our dermatology associates are here to help if you come into contact with poison ivy, poison oak, or poison sumac.

Poison Ivy
Poison ivy is a plant that can be found throughout the country, but its appearance varies depending on the region. In the East, Midwest, and South, poison ivy typically grows as a vine, while in the northern and western parts of the country, it tends to grow as a shrub. One key characteristic of poison ivy is that each leaf consists of three leaflets. A helpful rule to remember when identifying poison ivy is “leaves of three, let them be.”
The leaves of poison ivy are bright green and can turn red in the spring, as well as yellow, orange, or red in the fall. It’s important to be cautious and avoid contact with this plant, as it can cause an allergic reaction and result in a rash.

Poison Oak
Poison oak, with its three leaflets, bears a striking resemblance to poison ivy. However, it can be distinguished by its rounded leaf tips. Unlike its counterpart, poison oak leaves possess a fuzzy underside, noticeably lighter in color compared to the upper surface. Thriving as a shrub, this plant predominantly thrives in the western United States, surpassing any other region in abundance. The shrub may bear berries of either white or yellow hues.
Poison Sumac
Thriving as a woody shrub, the poison sumac plant boasts stems adorned with pairs of 7-13 leaves. To differentiate it from non-poisonous sumac varieties, one must observe its berries. Poison sumac showcases drooping clusters of green berries, while harmless sumac proudly displays upright clusters of red berries. Moreover, poison sumac finds its natural habitat in wet, swampy regions, particularly in the southeastern part of the United States.
Poison Ivy Rash Symptoms
Exposure to urushiol oil, regardless of the poisonous plant, will result in the same unpleasant consequence – an irritating, itchy red rash. The timeframe for developing this rash varies depending on the individual’s skin sensitivity, ranging from a few hours to a few days after initial contact with poison ivy, poison sumac, or poison oak leaves. It’s important to note that these symptoms can also manifest if a person touches an object that has been in contact with these plants. However, it’s crucial to understand that a rash caused by a poisonous plant is not contagious; you cannot contract a poison ivy rash by touching someone else’s rash. The symptoms associated with poison ivy, poison sumac, and poison oak include red and itchy skin, the presence of a skin rash, oozing blisters, red bumps (papules), redness, swelling, and irritation.
How Is A Poison Ivy Rash Diagnosed?
At The Art of Skin Dermatology, our dedicated team of professionals will carefully examine the rash, evaluate the patient’s symptoms, and engage in a thorough questioning process to determine if they have come into contact with a poisonous plant. It’s important to note that there are various allergens and irritants, apart from poisonous plants, that can also lead to contact dermatitis or the development of an itchy, red rash. In cases where a patient has not been exposed to outdoor environments or any plants, our team will diligently investigate other potential skin conditions or causes to ensure an accurate diagnosis.
Poison Ivy, Oak & Sumac Rash Treatment
Once a rash from poisonous plants has developed, there is no known cure. The best approach to poison ivy treatment is to avoid these plants altogether. It is crucial to familiarize yourself with their appearance and exercise caution when in their vicinity. Typically, rashes caused by poison ivy, oak, or sumac will subside within 3-4 weeks. During this time, our team may recommend over-the-counter creams like calamine lotion or a colloidal oatmeal bath, as well as prescribe oral medications for severe itching or steroid creams/injections to alleviate swelling and itching. In more severe cases or when the irritation affects mucus membranes (such as those in the eyes, nose, mouth, or genitals), prescription drugs like prednisone may be necessary to provide relief.

How To Prevent A Poison Plant Rash
To prevent the development of a rash, it is essential to familiarize yourself with the appearance of poisonous plants and take precautions to avoid contact with them. If you suspect that you have come into contact with poison ivy, poison sumac, or poison oak, consider the following tips:
- Apply rubbing alcohol to any exposed body parts and contaminated items. This can help remove the oil from the plants that causes the rash.
- Thoroughly scrub your hands and clean under your fingernails to effectively remove any traces of the oil. Using dish soap and lukewarm water is recommended for this purpose.
- Wash all clothing that may have been exposed to the plants after spending time outdoors. This will help eliminate any lingering oil.
- When outdoors, wear protective clothing and gloves to minimize the risk of direct contact with the plants. Long sleeves, long pants, and closed-toe shoes are recommended.
- When cleaning items that have been exposed to poisonous plants, such as gardening tools or equipment, wear rubber gloves to protect your skin from any residual oil.
By following these precautions, you can significantly reduce the chances of developing a rash from poisonous plants.
Poison ivy symptoms almost always include an itchy skin rash, redness and swelling and blisters. The rash is caused by an allergic reaction to an oily resin in the leaves called urushiol. Up to 90% of people who come into contact with poison ivy oil develop an itchy rash. You don’t have to be exposed to much—just 50 micrograms of urushiol, an amount smaller than a grain of salt, is enough to cause a reaction.
