Treating Skin Irritation continued...

Remove any remaining spines or barbs. Use tweezers to remove visible thorns. For tiny hairs or glochids, one method is to apply cellophane tape, and then peel it off -- along with any remaining barbs. If that doesn't work, one study found that applying a thin layer of household glue to the skin, topping it with a layer of gauze, and removing it after 30 minutes removed the majority of spines.

Ease pain and itching. A simple method to calm irritated skin is to use a cool water compress, says Katta. Just soak a clean washcloth in tap water and apply it to the skin for 15 minutes. You may also try an over-the-counter hydrocortisone cream or antihistamine to relieve itching and discomfort from a minor scrape.

Soothe skin with moisture-rich creams. With just a cut or scratch, pure petroleum jelly applied to the cut provides a little extra moisture that seems to aid in wound healing, says Katta.

Cover with a bandage. This can help prove a little extra protection during the day, then you can remove the bandage to let it air out at night, says Katta.

Monitor the area for signs of infection. "Anytime you have a long scrape in your skin, for instance because you bumped up against a saw palmetto plant, you can get a secondary infection if you're not careful," says Katta.

If irritated skin is not healing properly, you see pus, or an increase in redness or warmth over the span of a few days, then that can indicate that an infection is developing, she says. In that case, it's best to call your doctor.

Preventing Plant-Related Skin Irritation

When it comes to prevention, Katta says to keep your eyes open. "Some of these plants can sort of sneak up on you; you're not necessarily expecting to be brushed by a tree that has sharp leaves or by an agave plant on the ground."

If you'll be in an area where you may be exposed to irritating plants -- whether in your own yard or out hiking in the woods -- be sure to wear long sleeves and pants, and always use protective gloves when working in the garden. Keeping skin moisturized and healthy can also help prevent skin irritation from plants.
