Lantana camara is a fast-growing flowering shrub native to Central and South America, but now widely found across tropical and subtropical regions around the world. Known for its colorful, clustered flowers and strong aroma, lantana is often used as an ornamental plant — but beneath its beauty lies a long history of medicinal use.

Used in traditional medicine systems in Africa, India, Southeast Asia, and the Caribbean, different parts of the lantana plant — especially its leaves, flowers, and roots — are known for their antimicrobial, anti-inflammatory, and analgesic properties. However, lantana also contains compounds that are potentially toxic if consumed improperly, making safe and knowledgeable use essential.

Important Note: Lantana’s Toxicity Risk

Despite its medicinal value, Lantana camara is known to be toxic if ingested in large amounts, particularly to livestock, pets, and children. The berries — especially when unripe — and high doses of leaf extracts can cause liver damage, photosensitivity, and even fatal poisoning. Signs of toxicity include vomiting, diarrhea, labored breathing, and weakness.

Due to these risks, internal use of lantana should only be undertaken under the guidance of a trained herbalist or medical practitioner. Topical use is generally considered safer but should still be patch-tested, especially for sensitive individuals.

How to Use Lantana Safely

• Topical Use: Fresh leaves can be crushed and applied as a poultice for wounds, itches, or swelling.
• Inhalation: Dried leaves may be gently simmered for steam inhalation in respiratory conditions.
• Infused Oil: Lantana leaves infused in a carrier oil can be used on skin to reduce inflammation or repel insects.
• Avoid oral use unless advised and supervised by a healthcare provider familiar with plant toxicity management.
