It's not exactly a day at the spa, but cucumber slices are one of the simplest poison ivy home remedies. Either place slices of this cooling veggie on the affected area, or mash it up to make a cucumber "paste" and apply to the skin for soothing relief.
With its many medicinal qualities, it's no surprise that apple cider vinegar has also been shown to be a powerful poison ivy home remedy. One way to apply it is to soak a brown paper bag in apple cider vinegar, then place it on the rash to draw out the toxins.
A paste of baking soda smeared on your skin might help draw toxins to the surface, which is why the alkaline powder also is known as a natural pimple treatment. To soothe a poison ivy rash, especially one red with blisters, mix 3 teaspoons baking soda and 1 teaspoon water and apply the paste to the affected areas. When it dries, the baking soda will flake off, providing at least temporary relief. Another poison ivy home remedy is to soak in a cool bath with 1 cup of baking soda mixed in.
You can also use baking soda to treat oozing blisters caused by the rash. Mix 2 teaspoons baking soda in 1 quart (or 1 liter) water and use it to saturate a few sterile gauze pads. Cover the blisters with the wet pads for 10 minutes, four times a day. Note: Do not apply on or near your eyes.
If you're covered in an itchy red rash, save yourself some scratching by soaking in an oatmeal bath. Simply grind 1 cup oatmeal in your blender until it is a fine powder, then pour it into a piece of cheesecloth, the foot section of a clean nylon stocking, or the leg of an old pantyhose. Knot the material, and tie it around the faucet of your bathtub so the bag is suspended under the running water. Fill the tub with lukewarm water and soak in it for 30 minutes. You may find additional relief by applying the oatmeal pouch directly to the rash or pox.
Just like it soothes a nasty sunburn, the gel from an aloe vera plant can work wonders on a poison ivy rash. Apply the gel directly to the skin from the leaf or use a store-bought product for a quicker remedy.
If you're going to be in areas where there might be poison ivy, it's a good idea to carry rubbing alcohol with you. Apply it to the affected areas immediately after contact to slow down and minimize the discomfort; this poison ivy home remedy prevents urushiol, the chemical responsible for the rash, from fully penetrating your skin.
The acid in lemon juice is like a natural astringent, eliminating oil for myriad home and beauty uses. However, some people swear by lemon juice as a poison ivy home remedy, explaining that it cuts through toxic oils. Apply it soon after contact with the irritating leaf, before the plant's oil has time to fully get into your skin.
Washing the affected body parts in cool running water (and soap if it's handy) immediately after contact can help minimize the size and severity of the developing rash. Hot water can open pores and allow more toxic oils to seep in to your skin. You can also take a bath, with or without salt, to draw excess body moisture to the surface.
Apply cold compresses whenever the rash acts up, to tame the itchiness and prevent you from scratching; remember, sharp nails can open blisters to infection. Witch hazel can have a similar effect to reduce the rash, too. Pat on a small amount directly, or with cotton balls. If you need to dry a weepy poison ivy rash, try strongly brewed tea. Simply dip a cotton ball into the tea, dab it on the affected area, and let it air-dry. Repeat as needed.
