Poison ivy, poison oak, and poison sumac can turn your outdoor adventures into a nightmare. Contact with the toxic leaves, stems, or roots of these plants can lead to rashes and itching that last for 1-3 weeks. While waiting is the only way for the rash to completely disappear, there are several methods to alleviate the pain and itching caused by exposure to these plants.
Steps
Immediate Skin Care

Remove and wash clothing. Take off your clothes and place them in a plastic bag (if possible). Wash the clothes you were wearing during exposure to poison ivy as soon as possible.

Apply rubbing alcohol to the skin. You can use rubbing alcohol to dissolve the oils from poison ivy or poison oak. Since the toxic oil can gradually seep into the skin, applying alcohol helps prevent the oil from spreading. This method won't immediately relieve symptoms but will stop the oil from spreading further. Over-the-counter cleansers like Tecnu or Zanfel can also be used.

Rinse the affected area with cold water. Avoid using warm or hot water, as it opens pores and allows the toxin to penetrate deeper. If possible, hold the affected skin under running cold water for 10-15 minutes. If you're in the woods, you can rinse off with stream water.

Thoroughly wash the contaminated skin. No matter where the exposure occurred, rinse the area with water. If you touch the affected skin or the toxin gets on your hands, use a toothbrush to scrub under your nails to prevent the oil from lingering. Discard the toothbrush after use.
- Use dish soap (the kind that cuts through grease) to wash the rash area. Since the toxin adheres to the skin as an oil, using grease-cutting dish soap helps prevent the rash from spreading.
- If you use a towel to dry off after rinsing, wash it separately with the clothes you wore during exposure.

Avoid scratching the rash. Although the rash itself isn't contagious, scratching can break the skin and allow bacteria to enter. Avoid touching or popping any blisters that form, even if they ooze fluid. If necessary, trim your nails and cover the affected area.

Apply a cold compress to the affected area. Use a cold compress or ice pack for 10-15 minutes. Do not apply ice directly to the skin; always wrap the compress or ice pack in a towel first. If the rash is wet, let it air dry instead of using a towel.
Treating Itching from Poisoning

Apply lotion or liquid moisturizer. Calamine lotion, Capsaicin cream, or Hydrocortisone cream can help reduce itching. However, avoid applying immediately after exposure to the toxic plant, as rubbing can spread the oil. Apply a few hours or days after the itching begins. Capsaicin cream (often sold as a joint pain reliever in pharmacies) may initially cause a burning sensation but can soothe itching for hours.

Take antihistamines. Antihistamines are medications used to treat allergic reactions. Since exposure to poison oak and poison ivy triggers an allergic response, taking antihistamines can alleviate symptoms. Antihistamines typically only soothe symptoms of poison ivy, but if taken before bed, their anti-itch and drowsy effects can help you rest. Use oral antihistamines only; avoid applying them to the affected skin, as this can worsen the rash.

Take an oatmeal bath. Bathe with oatmeal or soak in Aluminum Acetate solution. If you don’t want to spend time buying medication, grind a cup of oatmeal and add it to warm bathwater. Avoid using very hot water, especially right after exposure, as it can open your pores.

Apply boiled jewelweed water. Crush jewelweed seeds and boil them in water. Strain the seeds and let the water cool, then use a cotton pad to dab it onto the rash. Although not extensively studied, this method has shown potential in reducing itching from poison ivy rashes.

Apply aloe vera. Aloe vera is a cactus-like plant. Its leaves produce a cooling gel. You can extract the gel directly from the plant and apply it to the rash or use bottled gel. If purchasing bottled gel, ensure it contains at least 90% pure aloe vera.

Rinse the rash with apple cider vinegar. Apple cider vinegar can help heal skin damage caused by poison ivy faster. Use a cotton pad to dab the vinegar onto the rash or dilute it with water in a 1:1 ratio to wash the affected area.

Use baking soda. Mix baking soda and water in a 3:1 ratio. Apply the paste to the rash to reduce blistering. Let the mixture dry and flake off naturally. Reapply every few hours for best results.

Use dairy products. If you’re not allergic to dairy, apply fermented buttermilk or yogurt to the rash. The proteins in dairy can help reduce blistering.

Use tea to treat the rash. Fill a bathtub with water and add 12 tea bags. Chamomile tea is recommended for its anti-inflammatory properties. Soak in the tea-infused water for about 20 minutes to relieve itching and discomfort. Alternatively, brew strong tea and use a cotton pad to apply it to the rash. Reapply every few hours.

Utilize frozen fruit peels. Apply frozen watermelon or banana peels to the rash. Watermelon rind acts as a cold compress, while its juice helps dry out blisters. On the other hand, banana peels provide cooling relief and soothe the rash.

Apply cold coffee. If you have leftover strong brewed coffee, use a cotton pad to dab and apply it to the rash. Alternatively, brew a fresh cup of coffee and let it cool in the refrigerator before applying it to the skin. Coffee contains chlorogenic acid, a natural anti-inflammatory agent.
Prevent Exposure to Poisonous Plants

Learn to identify poisonous plants. Avoid plants with the following characteristics:
- Poison ivy has clusters of three shiny leaves and red stems. It grows as a vine, often along riverbanks or lakeshores.
- Poison oak resembles a shrub and has clusters of three leaves like poison ivy. It is commonly found in the Western United States.
- Poison sumac is a woody shrub with 7-13 symmetrically arranged leaves. It thrives along the Mississippi River.

Bathe your pet if they come into contact with poisonous plants. Pets are generally not sensitive to poison ivy or oak. However, the plant's toxic oils can cling to their fur and cause allergic reactions in those who handle them. Use pet shampoo and wear rubber gloves when bathing them.

Bring preventive tools. If hiking or camping in areas with poison ivy, carry plenty of cold water bottles and rubbing alcohol. Applying cold water and rubbing alcohol immediately after exposure to poisonous plants helps prevent the spread of toxins and provides excellent pain relief.

Wear appropriate clothing when entering areas potentially containing poison ivy or oak. Opt for long-sleeved shirts, long pants, and socks. Ensure you wear closed-toe shoes and always carry spare clothes in case of accidental contact.
Tips
- Do not burn poison ivy. Burning releases toxic oils into the air, which can cause severe lung irritation, redness, itching, and even respiratory failure in severe cases.
- If a child is exposed to poison ivy, oak, or sumac, trim their nails short to minimize skin damage from scratching.
- Wash clothes, clean gear, and bathe pets. The oils from poison ivy and oak can linger on fabrics, equipment, and pets, causing allergic reactions upon contact.
- Apply deodorant to your arms and legs before going outdoors. It helps tighten pores, preventing toxic oils from penetrating the skin.
- Poison ivy and oak are related to mango trees. Individuals with a history of allergic reactions to these plants may also develop rashes when handling mango peels or sap. If you have such a history, ask someone else to peel mangoes for you.
- Remove poison ivy or oak from your garden by digging out small plants or cutting down larger ones. Use herbicides containing glyphosate or triclopyr (use with caution). Always wear long sleeves and gloves when handling these plants.
- Consider purchasing Oral Ivy from local pharmacies. Mix it with water and drink it. The tasteless solution works quickly to prevent rashes if taken before exposure or to alleviate itching and promote healing if taken afterward.
- Apply Caladryl lotion to treat poison ivy rashes.
- Always wear gloves while gardening to avoid contact with poison ivy, oak, or sumac.
- Avoid soaking in a bathtub after exposure to plant oils, as they can float on water and spread the rash.
Warnings
- Never burn poison ivy, oak, or sumac. The plant's sap can mix with smoke and cause allergic reactions if inhaled.
- If a rash appears on the eyes, mouth, nose, genital area, or covers more than a quarter of your body, consult a doctor for advice. Additionally, seek medical attention if the rash persists, worsens, or disrupts your sleep. A doctor may prescribe corticosteroid anti-inflammatory medication to relieve itching.
- Call emergency services (115) if you experience difficulty breathing or severe swelling. Immediate medical care is necessary if you are exposed to smoke from burning toxic plants.
- If you develop a fever above 38°C, notice yellow crusts or pus on the skin, or feel pain in the affected area, visit a doctor to rule out infection.
