The Pain of Poison Ivy
Before we discuss precautions and seek relief from home remedies, let me say right up front that I am not a medical professional, nor a professional herbalist… merely a concerned gardener, wishing to share important and helpful information about this “green scourge.” Folklore, hearsay and personal episodes aside, never, ever let the ill-effects of contact with “leaflets three” go unresolved. Sometimes severity of contact, as well as your personal tolerance/allergic reaction, will necessitate a trip to the doctor or nurse practitioner for professional assistance and is recommended for a rash that impacts the face, eyes, lips, causes uncontrollable itching, or becomes infected. A severe reaction, such as that caused by inhaling burning poison ivy, may include swelling and difficulty breathing. If so, dialing 911 or proceeding to the emergency room, is the proper reaction.
1. What does it look like?
Whether you call it by its botanical name (Rhus radicans or Toxicodendron radicans), or just poison ivy, the first step in interacting with this all-too-common pest (green monster?) is ID - become familiar with this plant. Leaflets three, let it be! Deep green, slightly wavy or scalloped leaf edges, with reddish stems. Found growing as a ground cover, rambling over stonewalls or anything in its path, and climbing high into trees.
2. Where does it grow?
Everywhere! Full sun, dappled shade, wooded areas, open fields, wet areas near waterways and hot, dry locations… a very adaptable pest!
3. When is it dangerous?
Always! All parts of this plant contain urushiol and can produce allergic reactions at any time of year. The oil is potent indefinitely, remaining viable on clothes and tools for years!
4. Can you burn it?
No! Doing so can produce horrific results, especially when the smoke is inhaled into the lungs. When burned, poison ivy oil becomes airborne… likewise with the use of mowers and line trimmers. Remain vigilant, so you can avoid this three-leaved menace… when avoidance in the backyard is impractical, then turn to controlling its spread. Such commercial controls are non-selective, so use with care, or you’ll kill desirable plants. Even more environmentally-sensitive controls (commercial or homemade) may include vinegar (regular white or 20% horticultural strength), citric acid, clove oil and other such components, but are also non-selective, so take care. They’ll also require a few repeat applications - eventually, repeated burning of foliage by these materials weakens the roots and discourages regrowth.
5. Can you you walk in poison ivy and not get it?
Possibly; however, be aware that your shoes and socks (and possibly your bare legs, if wearing shorts) will be covered with the oily resin (urushiol) and that handling them puts you at risk of an allergic reaction.
6. How can people prevent getting it?
Avoidance, through proper identification ~ children should be taught as early as possible. Ivy Block is applied before any possible contact, when gardening, hiking, etc.
Are you a gardener with poison ivy issues? This invasive pest can pop up anywhere the birds fly or the wind blows. So, even if you’re successful at maintaining a “safe zone” around your yard, it will creep right back in without invitation, despite your vigilance. Keep in mind that any garden tools may be suspect and that oils remain viable on them long after initial contact. Long pants, long sleeves and gloves may narrow the chance of direct exposure… just be careful and meticulous with your cleanup regimen. Protective gloves should be worn when handling and cleaning shoes, clothing and tools that have been contaminated with the oily resin.
Rubbing alcohol to cleanse exposed skin, followed by a thorough washing up with soap is recommended.
Don’t pat Fido if he’s been romping in a patch of poison ivy, at least not until after he’s been bathed (wear gloves for that event!).
7. What to do if you do get poison ivy all over you?
Depending on extent, intensity and individual tolerance, that trip to the doctor often includes Benedryl, or similar remedy, to shorten your time of misery, quelling your system’s reaction to this toxin.
Sitting back with a tall glass of iced tea, while you wait for those home remedies or prescriptions to work, is a no-no! No caffeine in any form - soda, coffee, tea, energy drinks, etc. Intensifies the itch! (Make it a lemonade.)
Tecnu! Wash thoroughly with Tecnu, as soon as possible. Put Tecnu in the wash with your clothes, as well. It draws out the oils, even hours after initial exposure. An alternative is to use dishwashing liquid. The degreasing agents draw out the oil from the skin… within a few minutes of rubbing it into the rash, itch relief occurs. Leave the dishwashing liquid in place overnight, wash off and reapply. Skin often clears in a couple of days. Either of the above can be used long after initial contact to dry the rash sites. The heavy duty laundry bar soap, Fels-Naptha, was always the traditional way to cleanse skin of oils, right after exposure. You may find soap made from jewelweed to be effective, as well. The aforementioned isopropyl alcohol seems to remove much of the oil and is followed by washing with soap.
Caladryl & calamine lotion often provide some relief during the healing process.
Lots of herbal and home remedies to lessen the misery of Poison Ivy. Plant-based include jewelweed (Impatiens/touch-me-not), sweet fern, plantain (applied fresh as a poultice or boiled and steeped as a tea and applied to rash), rhubarb stems, burdock roots, aloe vera, honeysuckle, polk salad root, milkweed. Many are brewed into a tea, allowed to steep and applied to rash… the tea is also use to make ice cubes for cooling, healing effects, when rubbed over the affected skin.
Baking soda paste applied to affected areas & allowed to dry. Some folks soak in a baking soda bath. Warm, prepared oatmeal, to which you add a little baking soda, is applied as a paste and allowed to dry. Epsom salts are also made into a paste and applied to the rash or, soak the area in an epsom salt solution. Aloe vera brings relief from the itch and hastens healing.
Banana peel - rub the inside of the peel across affected areas for cooling itch relief. Wash the area with hot water first, then follow up with the inside of that banana peel, applied to affected areas. Some recommendations include laying the banana peel with the inside against the rash, encasing the area with plastic wrap and leaving this in place for about an hour… itching should be relieved and healing hastened.
8. How come animals don't get poison ivy?
They can, although not according to vets and books on the topic. Of our domestic pets, dogs are the most likely to break out with the telltale rash. Less hair on their undersides accounts for this. The allergic reaction may be blamed on another allergen or even an insect related issue. Cats are generally well-protected with a heavy coat over the entire body. If a pet has contacted the oils, don thick rubber gloves, before giving Fido a thorough shampooing to remove the oils from his fur. A tea made of plantain leaves should relieve his rash and itching.
Although Fido may not exhibit a rash, he can be responsible for yours. It’s important to remember that the oils remain potent on your pet’s fur for some time, and that they will be transferred to your skin, as you pet the animal.
9. What benefit does poison ivy have to the natural world?
The good news is that downy woodpeckers, robins and about 60 other bird species, harvest the white berries to supplement their diet. The bad news is that they are responsible for sowing the seeds, as they fly hither and thither across the wild terrain… and your backyard! Raccoons, squirrels and other mammals also feed on the berries. Stems and leaves are eaten by the Eastern Cottontail, White-tailed Deer and Muskrat. The threadlike hairs from aerial roots are harvested by cardinals and goldfinches for nest construction.
10. Are there any medicinal purposes for poison ivy?
Seriously? Actually, yes! Well, evidently back in the late 18th century, after it’s introduction into England in 1640, medicinal properties of the fluid extracted from fresh leaves was discovered and it was used to treat a variety of internal and external maladies. It is officially listed in the United States Pharmacopeia, and remains in use by homeopathic practitioners for rheumatism, ringworm and other skin disorders.
Poison Ivy Myth Busters…
Myth: As the fluid runs from blisters, it spreads the rash to new areas. You can “catch” it from contact with the fluid from someone’s blisters. Answer: This fluid is serum, not the oily resin, so is impossible to spread in this way. Increased rash usually indicates varying amount of initial exposure, as well as differing reaction on various skin areas.
Myth: That someone can roll around in a bed of poison ivy and never develop a rash. Answer: About 30% of the population at large exhibits less sensitivity, but this can change with repeated exposure. So, never say, “never!”
Myth: Exposure to sun breaks down the urushiol, rendering it harmless. Answer: It can remain viable and toxic on objects for years, which explains why rashes show up in winter, long after plants have gone into dormancy. Also suspect is wood, upon which poison ivy once grew. Handling and burning such firewood may generate a reaction through both direct contact and smoke.
“Look, up in the tree… It’s a vine! No, it’s a bush! Wait, it’s a ground cover? It’s Poison Ivy!”
Here we find bindweed and poison ivy co-mingling,
as they scramble up a rough trunk, seeking sun.
Seemingly “Faster than a speeding bullet,” in its growth habit and ability to bring all gardening to a screeching halt. If you’re one of the many gardeners allergic to the toxic substance called “urushiol” (ooh-roo-she-all) in poison ivy (
Rhus radicans or
Toxicodendron radicans), you’ve probably lost valuable time from your daily pursuits and suffered considerably from at least one case of poison ivy rash.

Poison ivy appears to be on the increase, as never before; seemingly, with neither rhyme nor reason? Not so! Your PI Update ~ Not the update we wanted, but something you should know… Based on recent experiments, Duke University researchers project that the rising levels of carbon dioxide will accelerate the spread of poison ivy and bump up the urushiol concentration.
