The leaves of yellow archangel have a spicy flavor. They can be eaten raw in a salad or used as a base for soup. The flowers taste sweet. Yellow archangel is used as a remedy in a tea infusion.
From Wikipedia: “Lamium galeobdolon, commonly known as yellow archangel, artillery plant, or aluminium plant, is a widespread wildflower in Europe, and has been introduced elsewhere as a garden plant. It displays the asymmetric flower morphology, opposite leaves, and square stems typical of the mint family, Lamiaceae. The flowers are soft yellow and borne in axial clusters, with a prominent 'hood' (the dorsal lobe of the corolla). It spreads easily and so has been commonly used as an ornamental ground cover. It can be invasive in places where it is not native and caution must be taken when planting in these areas.”
“Yellow archangel is a large-leaved perennial plant with underground runners growing to a height of about 40 to 80 cm (16 to 31 in). The paired opposite leaves are stalked, broadly ovate with a cordate base and toothed margin. The underside of the leaves is often purplish. The flowers grow in whorls in a terminal spike. The calyx is five-lobed. The corolla is yellow, 15 to 25 mm (0.6 to 1.0 in) long, the petals fused with a long tube and two lips. The upper lip is hooded and the lower lip has three similar-sized lobes with the central one being triangular and often streaked with orange. There are two short stamens and two long ones. The carpels are fused and the fruit is a four-chambered schizocarp.”
“There are a number of closely related taxa which hybridize with L. galeobdolon and in some cases are not unequivocally accepted as distinct species but considered subspecies or varieties by many authors. Most well-known among these is variegated yellow archangel (subsp. argentatum), whose leaves often have variegation, showing as silver patches arranged as a wide semicircle. This, and in particular its large-flowered and even stronger-marked cultivar 'variegatum', is the taxon most often met with as a garden escapee.”
Yellow archangel contains essential oils, flavonoids, and sponins. It also contains various minerals, including calcium, phosphorous, iron, potassium, magnesium, zinc, and sulfur.
Every part of yellow archangel is edible. It is used as a base for aromatic tea blends and soups. The young leaves and shoots can be eaten raw in salads or steamed. The flowers are used as decoration for desserts.
Both the flowers and leaves contain anti-inflammatory and antibacterial substances. Used in a tea infusion, yellow archangel helps to energize, fights against inflammation, works as a diuretic, and stimulates digestion.
