Hiking in South Carolina offers beautiful trails, diverse wildlife, and lush vegetation. However, the state is home to several poisonous plants that can cause serious skin irritation and allergic reactions that range from mild to severe (anaphylaxis). The key to enjoying your outdoor experience is knowing how to identify them. This post highlights the three most common poisonous plants found in South Carolina, their effects and practical tips to avoid them.
Recognizing Common Poisonous Plants in South Carolina
Here are three of the most common poisonous plants that hikers may encounter:
Poison Ivy
Poison ivy is touted as the most common poisonous plant that hikers encounter. The vines are prolific covering available areas and climbing on surrounding structures whether natural or man-made, so they are often overlooked as hikers move through areas brushy areas. The poison ivy vine is easily recognized by the clusters of three shiny, pointed leaves.

Effects: Contact with poison ivy causes an itchy rash with some blistering due to an oil found in its leaves, viney stems and roots.
Where to find: It thrives in forests, along shaded trails and near water sources.
Poison Oak
Though less common in South Carolina than poison ivy, poison oak, like poison ivy, is found in wooded, shaded areas. Poison oak leaves resemble traditional oak leaves and are grouped in clusters of three. Poison oak, though common as a vine, can also be found in shrub form. Educate yourself on the appearance of poison oak varieties before hiking whether or not you have known sensitivities.

Effects: Similar to poison ivy, as it causes skin irritation and rashes.
Where to find: Usually found in wooded and brushy areas.
Poison Sumac
Poison sumac grows as a tall shrub or small tree with 7 to 13 leaflets arranged in pairs along a stem, ending with a single leaflet. The new growth can appear bright red and stunning in appearance from the distance. The leaves are smooth-edged and with coloring ranging from yellow to deep green in the Spring and Summer months to a flaming shade of red in Fall and Winter months. Poison Sumac produces beautiful flowers that attract numerous insects. While Poison Sumac is quite beautiful, it should be avoided.
Effects: Contact causes severe skin irritation and blistering.
Where to find: Prefers wet, swampy areas such as bogs and wetlands.
How Poisonous Plants Affect Hikers
The effects of poisonous plants vary depending on the plant, the amount of contact, and individual sensitivity. Most common reactions involve skin irritation, but more severe symptoms can occur due to indivdual sensitivities:
Skin rash and blisters: Common with poison ivy, poison oak, and poison sumac.
Burning and blistering: Seen with poison ivy, poison oak and poison sumac after sun exposure.
Allergic reactions: Some people may experience (anaphylaxis) severe allergic reactions with extreme swelling or difficulty breathing. If you have anaphylaxis or any other medical issues, hike prepared for personal safety or peace of mind.
If you encounter any of these plants while hiking:
Wash the affected area with soap and cool water immediately.
Seek medical attention if symptoms worsen.
Practical Tips to Avoid Poisonous Plants While Hiking
Avoiding poisonous plants requires both awareness and preparation. Here are a few practical tips to keep you safe while hiking in the South Carolina:
Learn to Identify Poisonous Plants
Familiarize yourself with the appearance of common poisonous plants before your hike. Use field guides (available at most WMAs and parks) or mobile apps (iPhone look-up features or Google Photo "ask feature") with clear photos and descriptions.
Do not touch plants you cannot identify.
Stay on Marked Trails
Poisonous plants often grow in brushy, shaded areas. Staying on well-maintained paths will reduce your likelihood of encountering poisonous plants.
Wear Protective Clothing
Wear long-sleeved shirts, long pants or leggings, and closed-toe shoes to create barrier between your skin and plants.
Avoid Touching Unknown Plants
If you are unsure about a plant, do not touch it. Even dead or dried plants still contain enough oils to trigger reactions.
Wash Skin and Clothes After Hiking
The oils that trigger reactions remain present on skin, clothing, and gear after the hike. Be sure to wash exposed skin with soap and cool water after hiking as soon as possible and launder your clothing immediately to avoid spreading the oils to other surfaces or clothing.
Keep Pets Away from Poisonous Plants
The same oils that adhere to your skin and clothing can easily adhere your pet's fur and transfer to you through simple contact. Keeping dogs leashed will help deter them exploring poisonous vegetation and reduce your risk of exposure later.
Carry a First Aid Kit
Always go prepared. Carry essentials in your first aid kit, including antihistamines, hydrocortisone cream, and calamine lotion to treat minor skin irritations and/or reactions. If you have any doubts, seek professional medical care.
What to Do If You Come In Contact With Poisonous Plants
Even taking precautions, accidental exposure to poisonous plants happen. Here’s what to do if you touch a poisonous plant:
Rinse immediately: Use cold water and soap to wash the area thoroughly as soon as possible. Carry extra bottled water for this possibility.
Clean under nails: Oils can get under fingernails from scratching affected areas and spread.
Avoid scratching: Scratching can worsen the rash not only leading to infection, but also spreading the oils to previously unaffected areas.
Apply soothing treatments: Use over-the-counter creams or cold compresses to quiet the burn and intensity of the reaction.
Monitor symptoms: Seek medical help if at any point you have concerns. Immediately seek medical attention if you develop swelling (especially around the eyes or mouth), difficulty breathing, fever or a widespread rash that covers a large portion of the skin surface. As a person with anaphylatic reactions, I can attest that severe reactions can get out of hand quickly if not managed properly.
Additional Safety Considerations for South Carolina Hikers
South Carolina’s diverse ecosystems mean poisonous plants can appear in many environments, from coastal areas to mountain trails. Keep these extra tips in mind:
Check local trail guides: Most parks, wildlife management areas and preserves provide information on not only poisonous plants, but also the beautiful plants that are specific to their area. It is important to note that some areas may have additional plants, i.e. poke berry, wild parsnip or even the moon flower (aka Datura), that are of concern to hikers and pet owners alike.
Be cautious during Spring and Summer: Plants are most active and toxic during growing seasons. It is easy to overlook them in dense foliage. Their beautiful coloring may catch you without warning. Be mindful of your surroundings.
Educate hiking companions: Share knowledge about poisonous plants with hiking companions. The pool of knowledge and extra eyes on the trail may prevent unwanted interactions with poisonous or suspicious looking plants.
Use insect repellent carefully: Be mindful of using insect repellants on exposed or affected skin as they can worsen the reaction.
Being mindful of your surroundings can lead to an enjoyable hiking experience. Educating and preparing yourself in advance will go a long way once you are on the trail.
