Many plants that grow along roadsides and in gardens are quickly dismissed as weeds. However, some have a long history of traditional use in herbal medicine. The plant shown in this image appears to be prostrate spurge (Euphorbia prostrata or a closely related Euphorbia species). While it has been used in traditional remedies in some parts of the world, it is important to know that many Euphorbia species produce a milky sap that can irritate the skin and eyes and should not be consumed without expert guidance.
Unlike edible plants such as purslane, spurge is not considered a common edible vegetable, and some species can be toxic.
What Is Prostrate Spurge?
Prostrate spurge is a small creeping plant commonly found in:
- Gardens
- Sidewalk cracks
- Lawns
- Roadsides
- Dry fields
It has:
- Reddish stems
- Small oval leaves
- Tiny greenish flowers
- Milky white sap when the stem is broken
Because many spurge species look similar, proper identification is essential.
Traditional Uses
In various traditional medicine systems, some species of spurge have been used for:
- Minor skin conditions
- Digestive complaints
- Hemorrhoids
- Wound care
However, traditional use does not mean a treatment is proven to be safe or effective.
What Does Research Say?
Researchers have identified plant compounds in certain Euphorbia species that may have:
- Antioxidant activity
- Anti-inflammatory properties
- Antimicrobial effects
Most of this research has been conducted in laboratories or animal studies. There is not enough high-quality evidence to recommend spurge as a treatment for medical conditions in humans.
Why You Should Be Careful
The milky sap of many Euphorbia plants can cause:
- Skin irritation
- Eye irritation
- Burning sensation
- Allergic reactions
If the sap gets into the eyes, it can cause severe pain and temporary vision problems. Wash the affected area immediately with plenty of water and seek medical care if symptoms are severe.
Is It Safe to Make Tea?
Despite some traditional practices, do not make tea or consume wild spurge unless it has been positively identified by an expert and you have guidance from a qualified healthcare professional. Some species are poisonous, and accidental ingestion can lead to nausea, vomiting, diarrhea, and other health problems.
Safer Herbs for Everyday Use
If you’re looking for herbs with well-established culinary uses, consider:
- Rosemary
- Thyme
- Sage
- Mint
- Basil
- Ginger
These herbs can add flavor to meals and have a longer history of safe culinary use.
Growing Beneficial Herbs at Home
Starting a small herb garden is an excellent way to enjoy fresh flavors year-round.
Popular choices include:
- Basil
- Parsley
- Rosemary
- Thyme
- Oregano
- Mint
These herbs are easy to grow in containers or garden beds and can be harvested as needed.
Important Safety Tips
- Never eat a wild plant unless you are certain of its identity.
- Many weeds have poisonous look-alikes.
- Avoid harvesting plants from roadsides, where they may be contaminated with pesticides, vehicle emissions, or other pollutants.
- Wear gloves when handling plants that produce milky sap.
Final Thoughts
Some roadside plants have fascinating histories in traditional herbal medicine, but not every wild plant is safe to eat or use as a home remedy. The plant shown appears to be a type of spurge, which should be approached with caution because many species contain irritating or potentially toxic sap.
If you’re interested in using medicinal plants, it’s best to rely on species that have been accurately identified and are known to be safe. For any health condition, consult a healthcare professional rather than relying on unverified claims found on social media.
