How to Identify Poison Ivy?

 Poison oak and poison ivy typically have a single stem with blooming branches and three green or reddish-green leaflets per leaf. In the autumn, poison ivy plants produce a green or off-white fruit, and occasionally, the leaves will develop black spots. Since the appearance might vary depending on the season, growth cycle, region, and climate, it is only sometimes possible to distinguish the plant based on its leaves. 


Why is Poison Ivy So Dangerous?

You must first understand that urushiol is the stuff that causes a poison ivy plant to be so dangerous. The Toxicodendron plant family contains urease, which can be found on the leaves, stems, roots, and even the berries of the plants. You won’t be able to tell which specific plant you came into contact with by the rash it causes. This is because poison ivy, oak, and sumac produce urushiol. 


Causes of Poison Ivy Rash

Poison oak’s fruit, leaves, stems, roots, and sap all contain urushiol, which is a light and colourless oil. Urushiol changes colour when exposed to air, going from brown to black. Plant leaves also have tiny black dots.


There are various ways to come into contact with urushiol:


By rubbing against the leaves or touching the sap of the poisonous plant.

Contacting an object with urushiols, such as pet fur or gardening tools.

By inhaling smoke produced when poisonous plants are burned.

Urushiol is also found in ginkgo fruit and mango skin, which can cause symptoms resembling poison ivy dermatitis.

About 90% of those who come into contact with poison ivy oil get an itchy rash. A reaction can be triggered by as little as 50 micrograms (g) of urushiol. Even if you’ve never had a poison ivy rash before, you can develop one at any time in your life.


Symptoms of Poison Ivy Rash

Usually, the poison ivy rash develops in a straight line depending on the way the plant scrapes against your skin. However, the rash can be more dispersed if it comes into contact with clothes and pet fur. Typically, the reaction begins any time between 24 hours to 72 hours after coming into contact.


Poison ivy rash symptoms and signs include:


Redness

Itching

Swelling

Blisters

Difficulty breathing if the smoke from burning poison ivy gets into your lungs.

Poison Ivy – Treatment

If you come in contact with poison ivy on skin or any other hazardous plant, wash your skin immediately. Within minutes, its oil might cling to your skin. So, use cool water and soap as it can aid in oil removal or stop oil from spreading. Products with specific cleaners, such as mineral oil, may be helpful. Some over-the-counter medications can aid with rashes’ discomfort and itching. These consist of:


Hydrocortisone creams  

Calamine lotion

Antihistamine tablets  

To ascertain whether you might have come into contact with a deadly plant, a medical professional will examine the rash, evaluate your symptoms, and ask you questions. In addition to poisonous plants, other allergens and irritants can result in contact dermatitis or an itchy rash. Your provider will rule out other skin disorders or causes if you haven’t been outside or in close proximity to plants.
