Henbit

Overview

Latin: Lamium amplexicaule

Common names: Henbit, Henbit dead-nettle

Family: Lamiaceae (Mint family)

Type: Annual herb, often a winter annual in mild climates

Lamium amplexicaule, commonly known as henbit dead-nettle, is an edible and medicinal plant found across much of Europe, Asia, and North America. In many regions it is one of the earliest wild greens to appear in late winter/early spring, and is often considered a weed in lawns, gardens, and disturbed soils.

Identification (Field Notes)

Growth habit

Low, sprawling to upright winter annual; often forms dense patches.
Square stems (mint family characteristic), sometimes reddish or purplish, especially in cold weather.

Leaves

Opposite, rounded to heart-shaped, with scalloped/rounded teeth.
Lower leaves on petioles; upper leaves sessile and “clasping” the stem (the epithet amplexicaule = “stem-clasping”).
Soft, somewhat hairy, but not stingy (unlike true nettles).

Flowers

Tubular, two-lipped, typically pink to purple.
Arranged in whorls at the upper nodes, often forming a “tiered” look.
Attractive to bees and other pollinators in early spring.

Habitat

Lawns, garden beds, roadsides, waste places, sunny to partly shaded disturbed ground.
In warm climates (e.g., Houston) it often appears in late fall, grows through winter, and flowers in late winter to spring.

Look-alikes / Confusions

Purple dead-nettle (Lamium purpureum): similar, but with more triangular leaves and often strongly purple-tinted upper leaves that do not clasp the stem.
True nettles (Urtica spp.): have stinging hairs and very different leaf/stem feel.

Constituents

Two new flavonol glycosides from *Lamium amplexicaule* L. and their in vitro free radical scavenging and tyrosinase inhibitory activities.

Reported/likely constituents include:

Flavonoids & flavonol glycosides – contribute to antioxidant activity and potential tyrosinase inhibition (skin/lightening and anti-browning relevance in vitro).
Phenolic compounds – general antioxidant and anti-inflammatory potential.
Tannins – astringent effect, mild antimicrobial support.
Volatile compounds (typical of Lamiaceae) – contributing to aroma and mild spasmolytic/relaxant actions in some mints.

Note: Most detailed phytochemical work is limited; much traditional use is extrapolated from family-level patterns and small studies.

Medicinal Uses

Historically and in folk practice, henbit has been used as a mild, gentle remedy:

Traditional/folk applications

Mild respiratory support – teas or infusions for coughs, colds, and mild fevers.
Gentle nervine and relaxant – sometimes taken as a mild calming tea.
Light diuretic and circulatory support – as a spring “cleansing” green.
Mild astringent – for minor digestive upsets (loose stool, mild irritation).

Modern research

Lamium amplexicaule showed growth inhibition of S. mutans in this study, suggesting potential relevance for:
- Oral health / dental plaque ecology
- Complementary approaches to caries prevention (still very preliminary)

In vitro work suggests:
- Free radical scavenging (antioxidant) activity
- Tyrosinase inhibitory activity (relevant to pigmentation processes, more studied in cosmetic/food contexts than in clinical herbalism)

Clinical posture

Generally regarded as a mild, food-like herb rather than a strong medicine.
Often used as part of spring tonics, mixed wild-greens teas, or in formulas rather than as a primary, stand-alone remedy.

Safety & Contraindications

Widely eaten as a food; no major toxicity reports in normal amounts.
Avoid if:
- Individual allergy to Lamiaceae family plants is known/suspected.
- Herb is harvested from contaminated lawns/roadsides (pesticides, herbicides, heavy metals, pet waste, etc.).

Pregnancy/lactation:
- No robust safety data. Culinary amounts are likely low risk, but avoid concentrated or long-term medicinal dosing without guidance.

Edibility

Abundance: common

Edible parts: leaves, young stems, and flowers

How to use

Raw: in salads, as a garnish, or in mixed wild green dishes.
Cooked: added to soups, stews, sautés, or egg dishes (e.g., frittatas, shakshuka).
Tea/infusion: fresh or dried aerial parts in hot water.

Flavor profile

Mild, slightly sweet to slightly green/herbal.
Far less pungent than many mints; usually acceptable in quantity as a cooked green.

Where

Sunny or partly sunny yards, garden beds, open disturbed urban areas, field edges.
Always harvest from chemical-free, uncontaminated locations.

When

Late fall, winter (in Houston), and spring – best harvested when young and tender, before plants become stringy or tough.
Flowers are a visual cue of peak aboveground abundance.

Nutritional value (general pattern for wild greens)

Vitamins (esp. A and C), minerals including iron, and assorted antioxidants.
Useful as part of early-season fresh green intake when cultivated vegetables are less available.

Culinary Uses & Recipes

Basic preparation ideas

Add chopped leaves and flowers to:
- Omelets, frittatas, or scrambled eggs
- Grain salads, pasta salads
- Pesto (alone or mixed with other greens)
Use whole tender tops as:
- A last-minute addition to soups and stews
- A wilted green with garlic and olive oil
