Flower and Fruit
The white, fairly large bilabiate flowers are in axillary false whorls of 6 to 16 flowers. The campanulate calyx is green and has 5 tips. The tube of the corolla is bent like a knee and the curved upper lip has a ciliate margin. The lower lip is gordate. The tube has 1 large and 1 small tip; there are 2 long and 2 short stamens under the upper lip. The calyx remains after flowering and protects the small nut. When the nut is ripe, slight pressure is sufficient to fling out the seeds.
Leaves, Stem, and Root
The plant is 30 to 50 cm high with an underground creeping stem from which the aerial stems grow. These are erect, quadrangular, grooved, hollow, and noded. The leaves are crossed opposite, petiolate, ovate to cordate, acuminate, and serrate. The plant has no nettle hairs. The plant is similar to the stinging nettle but has a different stem.
The flowers have a weak honeylike fragrance and a slimy-sweet taste.
The plant is common in Europe and central and northern Asia.
White Nettle flower consists of the dried petal with attached stamens of Lamium album as well as its preparations.
