Poison ivy appears in woodlands, parks, and backyards. If people touch poison ivy, it can cause an irritating and itchy rash.

Symptoms usually occur 24–48 hours after coming into contact with poison ivy. In some cases, they can present as soon as 30 minutes after contact. However, symptoms can take as long as 2 weeks to appear. Rashes will usually clear within 2–3 weeks.

Poison ivy rash symptoms include:

  • itching
  • swelling
  • a red rash
  • bumps or blisters
  • oozing
  • spots or streaks that are darker than the surrounding skin

Anecdotal remedies include the use of apple cider vinegar to relieve rash symptoms.

Here we look at how to use apple cider vinegar for poison ivy rash, other home remedies, and when to see a doctor.

There is no specific research to support apple cider vinegar as a treatment for poison ivy rash.

Some anecdotal evidence suggests that it could wash other types of poison off the skin, such as jellyfish stings.

Before applying any home remedy to a rash, it is important to take the following steps:

  • Wash the rash with soap and cool water. Avoid hot water as this can irritate the skin further.
  • Remove and wash any clothing that may have come into contact with the plant.
  • Use soap, water, and gloves to wash any other items, such as tools or shoes, that may have come into contact with poison ivy.
  • If a pet has come into contact with poison ivy, wash their fur with soapy water so that the oil does not transfer.
  • Avoid scratching the skin or bursting any blisters, as this can cause further irritation and increase the risk of infection.

These steps can help prevent the rash from worsening and spreading to other parts of the body or other people.

If people wish to use apple cider vinegar as a treatment for poison ivy rash, anecdotal reports recommend dipping a clean cotton ball into apple cider vinegar and applying it gently to the rash or using a small spray bottle. People can apply the vinegar several times a day, until the symptoms ease.

Poison ivy contains an oil called urushiol, which inflames the skin and causes an irritating rash. As well as poison ivy, other poisonous plants such as sumac and oak contain urushiol, and these can also cause allergic reactions.

Urushiol easily transfers to the skin or clothing when people touch poison ivy. Although the rash is not contagious, the oil can also pass to other people’s skin or clothing via touch.

Poison ivy does not affect most pets, but if an animal touches poison ivy and brushes past someone, the oil can transfer from their fur to human skin or clothing.

The more exposure that people have to plants that contain urushiol, the more likely they are to have a severe reaction.

People may find that applying apple cider vinegar can help ease symptoms of a poison ivy rash. Other home remedies or OTC treatments may also be effective.

A poison ivy rash should disappear within a few weeks. If it lasts longer, gets worse, or shows no improvement after 7–10 days, people should see their doctor.

People should seek immediate medical attention if they have any symptoms of a severe allergic reaction or infection.
