Its Summer, Protect Yourselves from Poison Ivy
Poison ivy, oak and sumac are closely related plants, and may be found growing in similar environments in the US.
In fact, all 3 grow throughout the country. except Hawaii, Alaska and parts of Nevada.
Poison ivy is found throughout the US, Poison sumac is distributed mostly on the East Coast from Maine to Florida, and Poison oak is found along the West Coast and the south from Texas to Florida and as far north as Illinois.
While irritating and uncomfortable, poison ivy is not usually dangerous, unless the oil is aerosolized from burning.
Inhaling the fumes can trigger an allergic reaction in our lungs.
Nearly 75% of the population of the US will break out into a rash when exposed to the plant leaves. Only 25% appear to be resistant to the contact dermatitis that results from exposure to the oil in the plant.
The rash can be unbearably itchy if left untreated.
However, while your primary care physician may want to prescribe a corticosteroid to address the symptoms, there are much safer treatments you may begin at home that do not come with lots of side effects.
Steroids are commonly prescribed for a number of different conditions, including contact dermatitis, asthma, ulcerative colitis, cancer and arthritis.
They can be given topically, by injection, through inhalation or by mouth.
In each case the medication is linked with significant side effects, including fluid retention, elevated blood pressure, osteoporosis, mood swings and increased risk of infection.
In other words, these are drugs we all want to steer clear of as much as possible.
Learn to recognize the plants, as prevention is the best medicine and the treatments you can use at home to alleviate the symptoms as your skin heals.
The old adage, “leaves of three, let them be,” is helpful to identify poison ivy and poison oak, but poison sumac grows with 7 to 13 leaves on 1 stem.
However, depending upon your geographic location, species of the plant and the local environment, even the poison ivy plant may look different.
To reduce your chances of coming into contact with the plants, learn how to identify local varieties and differentiate them from other similar looking plants.
The Eastern poison ivy plant (Toxicodendron radicans), typically has small hairs on the leaves and grows on rope-like vines that may grow up a tree or along the ground. They have 3 shiny, green leaves that turn Red in Autumn. Despite turning color in the Fall, the leaves still contain the oil that causes the rash.
Western poison ivy (Toxicodendron rydbergii), grows as a low shrub with 3 leaves and does not climb.
The Eastern species rarely grows west of mid-Kansas, while the Western variety populates most states, except the southeastern US, either species of Poison ivy may have white or yellow flowers and produce green-yellow or amber colored berries.
The contact dermatitis we get from Poison ivy is the result of a reaction to the oil in the plant, urushiol. This oil is in the flowers, stem, leaves and roots. It takes very little of the oil to cause the reaction and the oil remains active in the plant long after the plant has died.
Exposure to an amount less than a grain of salt may cause a significant reaction in the highly allergic.
The rash typically begins in the 1st 12 to 72 hrs after exposure to the plant, or any piece of clothing, lawn equipment or pet on which the oil has been deposited.
While Poison ivy is not truly contagious, if touched someone who has the oil on their can be transfered to your skin, one may share the experience.
Within a couple of hours of contact with the urushiol, it is absorbed and metabolized.
The immune cells recognize it as a foreign substance, sending out cytokines and white blood cells to take care of the invader.
In this process, some of your normal tissue is damaged, which results in the symptoms you experience. In some cases, you may not react with your 1st or 2nd exposure, leading you to believe you will not get the rash.
However, increasing numbers of people have the allergic reaction to urushiol with repeated exposure.
So, if you did not develop the classic Poison ivy rash the 1st time you were exposed, you may the 2nd or 3rd time.
Symptoms of the Poison ivy rash appear on the area of skin exposed to the oil, and any other areas to which the oil transferred.
In other words, if you touched the plant then scratched your nose and swatted a fly on your arm, you’ll likely develop symptoms on your hand, nose and arm.
The symptoms of Poison ivy, oak and sumac include, the following;
- Weeping at the blisters
- Pain or burning at the site
- Lesions can continue to appear for up to 2 weeks
- Difficulty breathing if the plant was burned and you inhaled the fumes
- Blisters may be in streaks depending upon how the oil was deposited on the skin
As much as possible, refrain from scratching the rash as bacteria under your nails can infect the broken skin caused by the blisters.
Keep the area clean with soap and water to reduce the potential for infection. In most cases you can treat Poison ivy at home, unless you have breathed in plants that had been burned or you begin to have trouble breathing.
It may also be necessary to see your doctor if:
- The reaction on your skin is severe or widespread
- Your skin continues to swell over several days
- The rash affects the area on or around your eyes, genitals or mouth
- Your blisters begin oozing pus
- You have a fever greater than 100 F (37.8 C)
- The rash does not improve significantly, or get better, within a few weeks
If you find Poison ivy in your yard there are several precautionary tactics to prevent getting the rash. The 1st is to keep exposed skin away from the plants.
If there is Poison ivy in a wooded area and decide to leave it, ensure the rest of your family and neighbors who may use the area are aware of the situation.
If you are clearing an area of garden that may have Poison ivy, oak or sumac, or if you are spreading a new load of mulch, wear long sleeves, long pants and gloves.
Depending upon your mulch supplier, Poison ivy plants and the potent, active oil may have been mulched with the wood chips.
Once out of the garden, remove your gloves and clothing as described below and wash your hands and any exposed skin.
Hose off your garden equipment with mild soap and ensure your dog did not follow you into areas of the garden that may have Poison ivy, oak or sumac.
Still, if you suspect your dog or cat has been in or near Poison ivy, prudent dictates giving them a bath to prevent the oil from soaking to their skin or from transferring the oil to you or one of your family members.
Be aware the oil in the plant is hardy and remains potent long past the life of the plant.
Most cases of Poison ivy contact dermatitis occur in the Summer months, but some cases may show up in Winter.
Dr. David Adams, dermatologist at Penn State University, has seen cases near Christmas when people buying live trees rip dead vines off the trees, not realizing they are Poison ivy.
Use a safe and effective method to kill the plants that are in your yard without resorting to chemicals that damage the environment and may poison you too.
No matter what method you use to remove the plants, it is Key you cover your skin with long pants, long shirt and gloves, as it may save you days of itching and burning.
Duct tape your pants around your socks and your shirt around your gloves, ensuring the gloves you are using do not have holes.
Once you are done treating or pulling the Poison ivy, you will want to strip off the clothes, being careful that you do not touch the outside of the clothes with your bare hands. You may want to have a friend remove your gloves while they are wearing disposable vinyl gloves.
Then, donning a pair of vinyl gloves yourself, remove the remainder of your clothes and immediately wash them 2X in hot water.
This may seem extreme, but could save you days of discomfort and pain.
Poison ivy is a perennial plant, which means it could take 3 or 4 tries to eradicate it.
The fastest way to get rid of the plants is to dig them up, ensure you get at least 8 ins deep into the soil to remove as much of the root system as possible.
Disposal of the plants you dig up is another important factor to reduce the spread of the oil. Do not compost, shred or burn the plants as this causes the oil to spread. Instead, bag the plants and roots in plastic and dispose of them in the garbage.
Once the plants are removed, cover the area with cardboard or mulch to help prevent regrowth of the plants. Watch the area around the cardboard for tiny plants that may grow from roots you may have missed.
If suiting up HazMat style and digging up the plants is not your style consider a nontoxic solution of 1 cup of salt, 1 gallon of water and a tablespoon of dish soap.
Mix this solution thoroughly and pour it into a sprayer.
Use the stream setting on the sprayer if the plant is close to other plants you would like to save, as this formulation will kill all plant growth.
If you know you’ve been exposed to Poison ivy, oak or sumac, take precautions to minimize any potential outbreak.
James Brauker, Ph.D., spent 25 years as a biomedical scientist studying skin inflammation. In this video, he explains the method he has used to reduce or eliminate outbreaks of contact dermatitis from the urushiol oil.
Once you have an outbreak, for the most part you may treat it at home, using natural products to help reduce the swelling, itching and pain without resorting to over-the-counter medications.
Try a combination of the following products to address each of the different symptoms.
Left untreated, Poison ivy will often resolve spontaneously within 2 to 3 weeks. These treatments may help your body heal faster and will often relieve the pain and itching from the contact dermatitis.
To Remove the Oil
Alcohol wipes may help to remove the oil from your skin if you do not have immediate access to soap, water and a washcloth.
Remove the oil as quickly as possible after exposure to reduce the severity of the rash and possibly eliminate the potential of getting it.
Remember to wipe every area of skin that may have contacted the plant or equipment that had touched the plant.
Get between your fingers and use a brush to clean under your fingernails.
Oil that remains under fingernails may be spread when you touch other parts of your body. Use cool water and not hot to avoid irritating your skin or opening your pores, as this will allow the urushiol to be absorbed more quickly.
Another astringent you can use to remove the oil is the juice from a fresh lemon.
Squeeze the juice onto a cotton pad and wipe the area. While this may remove much of the oil, it is important to also wash and use a washcloth to continue to remove the oil. Wash the washcloth in hot water through 2 cycles to ensure the oil has been removed.
Treating the Itching and Inflammation
Cold compresses may help soothe the skin and reduce the discomfort. Soaking the area in a lukewarm oatmeal bath may help reduce the inflammation and soothe your skin. You may use oatmeal in a container that accommodates the entire area or take an oatmeal bath. Filter the water as it leaves the tub or pour the fluid down the garbage disposal from a small basin used to soak an area of your body, so it does not clog your drain.
Baking Soda in a lukewarm bath is recommended by the American Academy of Dermatology to soothe the skin and reduce the inflammation. The inside of a banana peel or watermelon rind may also help reduce the itch from the rash.
The rash is very itchy, but you must refrain from scratching as much as possible. Bacteria under your fingernails may trigger a skin infection and scratching increases the damage to your skin and the potential for scarring. If the blisters from the rash do break open, leave them alone and cover them to prevent infection.
Reducing the Reaction
A paste of bentonite clay and water covering the area where you 1st notice the contact dermatitis may reduce the reaction your skin experiences, and therefore your symptoms. Bentonite clay is a natural clay that may be purchased at your local health food store.
Speed the Healing
Soak a paper bag in apple cider vinegar and lay it across the rash. If you cool the apple cider vinegar 1st it will also help to reduce the itch as the vinegar helps to speed healing of the rash.
Cool the Burning
One of the symptoms of contact dermatitis from Poison ivy is a burning sensation over the rash area. The gel from an aloe vera plant may help to cool the burn from the rash in much the same way it helps soothe a sunburn.
With all of the above in mind, have a terrific Summer.
