Home Remedy Treatments for Poison Ivy

Pets can sometimes give you a rash from poison ivy, oak, or sumac.

The best way to treat poison ivy, oak, and sumac? Avoid it like the plague! Here are some home remedies on how to do just that.

Know the plant so you can avoid it. Find out what the plant looks like in the area you live or plan to visit, because appearance will vary, even within a state. For instance, poison oak that grows in Northern California doesn't look like poison oak native to Southern California. Typically, poison ivy is a vine or a low shrub with grayish white berries and smooth, pointed leaves that are usually clustered in groups of three. The reddish leaves turn green in the summer and redden again by autumn. Poison oak is a shrub or small tree with greenish white berries and oak-like leaves that, again, usually appear in groups of three. Poison sumac is a woody shrub found in swampy, boggy areas that has smooth-edged leaves and cream-colored berries. The leaves of poison sumac retain their reddish color and aren't grouped in threes.


Spotting the plants isn't always easy. Poison ivy can mimic other plants, such as Virginia creeper, and can twine itself around English ivy. Even doctors who warn their patients to avoid these plants can't always identify them. You'll decrease your chance of being exposed to one of these plants, however, if you become familiar with their typical appearance.

Here are some tips:

  • Poison ivy. Poison ivy plants have serrated, pointed leaves that appear in groups of three leaflets. The leaves are green in summer but are reddish in spring and fall. While their appearance can vary, poison ivy plants are found everywhere in the United States. In the East, Midwest, and South, it grows as a climbing vine. In the West and northern states, poison ivy resembles a shrub. Poison ivy rarely appears above 5,000 feet.
  • Poison oak. Like poison ivy, poison oak has leaves of three and the shrub's size differs depending on location. In the Southeast it appears as a small shrub, while in the West, poison oak appears as a large shrub. It has greenish-white berries and oak-like leaves.
  • Poison sumac. The leafy one of this threesome is poison sumac, a small shrub with two rows of 7 to 13 leaflets. Sumac prefers swampy bogs of northern states and swamps in southern states. Its leaves are smooth-edged and remain red; the plant has cream-colored berries. Unlike poison ivy and oak, poison sumac does not produce leaves in groups of three.

Don't Touch! Touching the oil after initial contact is what spreads the rash -- something easily done. For example, say you unknowingly walk over poison ivy and the oily residue sticks like glue to your hiking boot. Later, you remove the boot, unwittingly touching the residue in the process. Since few people wash their hands after removing boots, the oil easily spreads from the hands, to the face, and even to the genital area should you make the unfortunate decision to use the bathroom. The damage is done by the time the rash breaks out. Touching the rash once it appears does not spread the oil -- or the rash.

Cover up. Long pants, long-sleeved shirts, boots, and gloves provide a barrier between you and th plant's oil. This is especially important if you're sensitive and you know you're going to be in an area that might contain poison ivy.

Don't let your pets romp in wooded areas. If you get a rash from poison ivy but can't remember being near the plant, you may have your pet to thank. If your dog or cat strolls through a patch of poison ivy, the oils may cling to the animal's fur. Pat or pick up the pet, and the oils rub off on you. The same is true of anything that comes in contact with oil from poisonous plants, including gardening tools, bicycle tires, and golf balls. Once there, the oil can remain active for a long time, so you can get poison ivy again and again without touching the plant itself if you don't use care when handling these outdoor items and rinse them off after each use.

Rinse your clothes outside. If you think you've had a close encounter with poison ivy, the oil may be all over your clothes. If you walk inside your home without rinsing your clothes, you may transfer the oil to rugs or furniture. Water deactivates the oil, so once your clothes are soaked, they're safe. It's also a good idea to rinse off camping, hunting, and fishing gear so you don't start off your next vacation with a case of poison ivy. Since poison plant oils don't just disappear, it's crucial to wash anything that has had contact with the victim or the oil, including clothing, boots, pets, other people, sleeping bags, fishing poles, walking sticks, etc. Use gloves when cleaning pets, people, and objects that may have had contact with the oil. Don't forget your shoes, which can pick up oils from twigs or vines. At night, if you take your shoes off by grabbing the sole or the heel, you may grab onto more than you bargained for and end up with a nasty case of poison ivy. 

Head for water fast. This should be your first step if you suspect you've gotten into poison ivy. Don't hesitate -- the sooner you're soaked, the better. Whether it comes from a stream, lake, garden hose, or faucet, if you can get to water within five to ten minutes after contact with the plant, you may be able to wash off the oil before all of it sinks in.

Carry rubbing alcohol with you. The oil from poison ivy isn't absorbed into the skin all at once; it sinks in fairly gradually. If you move quickly enough, you may be able to use rubbing alcohol to extract some oil from the skin. If you think you've been exposed to the weed and you're heading back inside for the day, wash down the exposed areas with rubbing alcohol and then rinse well with water. Don't use a cloth wipe, which may simply pick up the oil and transfer it somewhere else. And don't use the alcohol near your eyes.

Try a protectant. Consider using a product called IvyBlock, which is a protectant that helps diminish contact with urushiol. This can be applied before heading out into potential poison-plant territory.
