Updated: Feb 6


Harvested purple dead nettle. Notice the heart shape of the leaves and that the upper leaves have a deep purple hue.

Being a member of the mint family, notice the square stem and the cluster of plants.

Purple Dead Nettle (Lamium purpureum) - An early spring weed that grows like gangbusters. It is hardy and can self-pollinate, which allows it to spread quickly in moist, sunny locations. Although it is not native to North America, it can be found in every state of America. Luckily, it is not a deadly plant, and it even does not have deadly look-a-likes. The name "dead nettle" comes from it looking similar to stinging nettles (Urtica dioica), it does not sting, thus the "dead". Nevertheless, its medicinal properties make it effective for wound healing. Additionally, it exhibits antihistamine properties, potentially relieving seasonal allergy symptoms. Traditionally used for insect bites, rashes, cuts, bruises, and scrapes.


  • Astringent/Styptic - Its astringent properties have been used to staunch bleeding, including heavy menstrual bleeding when used internally as a tea or tincture.

  • Antimicrobial - Purple dead nettle has antibacterial and antifungal properties, making it useful in combating topical and internal infections.

  • Vulnerary - Purple dead nettle is commonly used externally as a poultice or in salves to treat cuts, bleeding wounds, rashes, bruises, and various skin irritations. Its applications extend to soothing itchy, dry, irritated, chapped, or sore skin.

How to Harvest

Purple dead nettle is a favorite plant for bees and ants alike, so harvest carefully. All aerial parts of the plant can be utilized for herbal remedies. On a sunny morning, after the dew has dried up, snip or snap the stem about two inches from the ground. Turn the plant over and tap gently to encourage ants to move along. Avoid harvesting from roadsides or locations where toxin build-up or pesticide use is a concern.


After harvesting, it's recommended to give the plants a quick rinse in cold water to remove any remaining ants. Lay the plants out to dry on a paper towel or a drying screen, rotating the pieces to ensure even drying. Often, a few days is all that is needed for them to be dry enough to use in herbal preparations. You can also eat the plants fresh if you prefer. I am not a big fan of their flavor, but many people like to use them in soups, salads, pestos, and smoothies.
