Näkökihmistä

Näkökihmistä, also known as the Finnish Finnish name for the plant *Galeopsis tetrahit*, is a common annual herb belonging to the Lamiaceae family. It is native to Europe and Asia but has been introduced to other parts of the world, where it can sometimes be considered an invasive weed. The plant is characterized by its square stems, which are often hairy and have a reddish tinge. Its leaves are ovate to lanceolate, toothed, and grow in opposite pairs.

The flowers of Näkökihmistä are typically two-lipped and appear in whorls in the upper leaf axils. They are usually pink to purplish, often with white markings and a spotted lower lip. Flowering occurs from early summer to autumn. The plant produces small, nutlet-like fruits.

Näkökihmistä thrives in disturbed soils, often found in fields, meadows, roadsides, and waste areas. It is known for its rapid growth and ability to produce a large number of seeds, contributing to its widespread distribution. Despite its weedy nature, the plant has been traditionally used in some folk medicine practices, though scientific evidence for its efficacy is limited. It is important to distinguish Näkökihmistä from other similar-looking plants in the *Galeopsis* genus.
