Snake plants, also known as mother-in-law’s tongue or Sansevieria, are popular houseplants known for their hardiness and striking appearance. Their long, pointed leaves may tempt you to reach out and touch them, but you might be wondering – is it safe to touch a snake plant? Here’s a look at what can happen if you touch a snake plant and how to handle these intriguing plants safely.
Can touching a snake plant hurt you?
In most cases, touching a snake plant is not harmful and nothing bad will happen. The leaves may be sharp and poke you, but they typically won’t break the skin. Some people may experience mild skin irritation from touching snake plants, especially those with sensitive skin. The sap inside the leaves contains crystals called raphides that can cause irritation for some when exposed to the skin. However, serious reactions are very rare.
Skin irritation
The most common reaction to touching a snake plant is mild skin irritation or redness at the site of contact. This is caused by the raphides, which are needle-like crystals of calcium oxalate found in the plant’s tissues. Contact with the sap containing raphides can cause a reaction similar to a bee sting or nettle in sensitive individuals. The irritation is usually temporary and subsides within a few hours.
Allergic contact dermatitis
In rarer cases, some people may experience an allergic reaction called allergic contact dermatitis after touching certain plants like snake plants. This causes a red, itchy rash at the site of contact. It occurs when the immune system overreacts to the plant proteins. Those with pre-existing skin conditions like eczema are more prone to such reactions. The rash usually resolves on its own within a week or two.
Phytophotodermatitis
Phytophotodermatitis is another uncommon reaction that can occur in some individuals after contact with snake plants, especially when the skin is then exposed to sunlight. This causes reddish pigmentation and blistering rashes on the skin 24-48 hours after exposure. It occurs when the sap containing photosensitizing chemicals reacts with sunlight. The discoloration usually fades over several weeks or months.
Can a snake plant poison you if eaten?
While not deadly poisonous, snake plants contain calcium oxalates and other toxic compounds that can cause symptoms if ingested. Mild exposure can cause irritation in the mouth, lips and throat. Larger amounts may lead to more severe reactions like difficulty swallowing, vomiting, diarrhea or burning sensations.
Children and pets are at higher risk if they bite or eat parts of the snake plant. If ingested, rinse out the mouth right away and seek medical care if any concerning symptoms develop. With proper treatment, most exposures only cause minor discomfort.
How to handle snake plants safely
While serious reactions are very uncommon, you can take some simple precautions when handling snake plants:
- Wear gloves when repotting or pruning to avoid skin contact with the sap.
- Wash your hands after handling even if you wore gloves.
- Keep plants up and out of reach of children and pets.
- Avoid getting the sap in your eyes or mouth.
- Seek medical care right away if you experience a severe reaction.
What to do if you touch a snake plant
If you do touch a snake plant with your bare hands, here are some tips for minimizing reaction:
- Wash the area thoroughly with soap and water. This helps remove any sap or raphides.
- Apply a cold compress or ice pack to ease redness and irritation.
- Use hydrocortisone cream to relieve itching or irritation.
- Monitor for any signs of allergic reaction like redness, swelling, rash.
- Avoid direct sun exposure which can worsen phytophotodermatitis.
- See your doctor if a rash or other reaction develops.
Conclusion
For most people, casually touching a snake plant will not cause any issues. Mild skin irritation is possible in sensitive individuals due to the raphides in the sap. Allergic reactions or phytophotodermatitis are very rare. Take some basic safety precautions when handling snake plants, and promptly wash any skin that contacts the leaves or sap. With proper care, you can safely keep these statement-making plants in your home.
