Purple dead nettle (Lamium purpureum) is a common yard weed with a surprising range of uses. It’s edible, has a long history in folk medicine as an anti-inflammatory and wound-healing herb, and serves as one of the first nectar sources for bees in early spring. Despite the name, it’s not related to stinging nettle and won’t irritate your skin.
A Nutritious Edible Weed
The entire above-ground plant is edible: leaves, stems, and flowers. The flavor is mild and slightly earthy, similar to other plants in the mint family. Young leaves and tops are the most tender and work well raw in salads, blended into smoothies, or stirred into soups and pesto. The purple-tinged upper leaves are rich in vitamins A and C, iron, and fiber.
You can also dry the leaves and steep them as tea. The taste is grassy and mild enough to blend with stronger herbs like mint or lemon balm. If you’re foraging, harvest from areas you know haven’t been treated with herbicides or pesticides, and pick plants that are actively flowering for the best flavor.
Traditional Medicinal Uses
Purple dead nettle has been used in European herbal medicine for centuries, primarily as an external remedy for cuts, scrapes, and minor skin irritation. The plant contains flavonoids and other compounds with anti-inflammatory and astringent properties, which is why herbalists have long applied it to wounds to reduce swelling and encourage healing.
Internally, it’s been used as a mild tea for seasonal allergy symptoms and to soothe irritated throats. Some herbalists also recommend it for its gentle diuretic effect. While clinical research specifically on purple dead nettle is limited, broader studies on the Lamium genus show promising biological activity. White dead nettle (Lamium album), a close relative, has demonstrated broad antibacterial effects, particularly against certain types of bacteria. Other species in the genus have shown antifungal activity against Candida, a common yeast responsible for many infections.
How to Make a Purple Dead Nettle Salve
One of the most popular ways to use purple dead nettle is as a homemade healing salve for dry skin, minor cuts, and bug bites. The process starts with making an infused oil: fill a glass jar one-quarter to one-half full with crumbled dried purple dead nettle, then fill the jar nearly to the top with a carrier oil like olive oil or sweet almond oil. Let the jar sit in a sunny window for four to six weeks, shaking it occasionally, then strain out the plant material.
To turn the oil into a salve, gently warm about 1.65 ounces of infused oil with 0.25 ounces of beeswax until the beeswax melts, then pour into small tins or jars and let it cool. You can combine purple dead nettle with other dried herbs in the infusion stage for different purposes. Calendula, yarrow, or plantain make a good first-aid blend, while arnica and comfrey root create a salve better suited for sore muscles and joint aches.
Benefits for Pollinators
Purple dead nettle blooms very early in the season, often appearing in late winter or the first weeks of spring when almost nothing else is flowering. This makes it a critical food source for pollinators emerging from dormancy. Honeybees, bumblebees, and digger bees (a group of large ground-nesting bees) all feed on its nectar during this lean period.
If you spot purple dead nettle growing in your yard before you’ve started mowing for the season, leaving it alone for a few weeks gives local bee populations a meaningful boost. The plants complete their life cycle quickly, dropping seeds and dying back on their own as warmer weather arrives, so they won’t take over a lawn permanently.
How to Identify It Correctly
Purple dead nettle is frequently confused with henbit (Lamium amplexicaule), a close relative that’s also edible and looks strikingly similar. The key difference is in the upper leaves. Purple dead nettle has triangular, heart-shaped leaves with scalloped edges that are distinctly purple or reddish at the top of the plant, and each leaf sits on its own short stem (petiole). Henbit’s leaves are rounder with deeply scalloped edges and clasp directly around the main stem without a petiole.
Both plants grow low to the ground, have square stems typical of the mint family, and produce small tubular pink-purple flowers. Ground ivy is another common lookalike, but it spreads along the ground with longer runners rather than growing upright. Misidentifying any of these three for each other isn’t dangerous since all are non-toxic, but knowing which one you have matters if you’re foraging for a specific flavor or making herbal preparations.
Nutritional and Antioxidant Content
Purple dead nettle is notably high in antioxidants, particularly flavonoids, which help protect cells from oxidative damage. It also contains iridoid glycosides, compounds found across the mint family that contribute to its anti-inflammatory reputation. The purple coloring in the upper leaves comes from anthocyanins, the same class of pigments found in blueberries and red cabbage, which have their own well-documented antioxidant effects.
For a “weed,” it packs a respectable nutritional punch. Adding a handful of fresh leaves to a salad or smoothie a few times a week during its short growing season is an easy, cost-free way to add micronutrients and antioxidants to your diet.
