White dead-nettle flowers contain mucilage, essential oils, flavonoids, tannins, saponins, phenolic carboxylic acids, phosphohydrolases and oleanolic acid (about 0.15%).

White deadnettle flowers have an antipruritic, antiphlogistic effect. In addition, they inhibit secretion, have a slight surface anaesthetic effect, are astringent (tanning agents) and inhibit capillary permeability. A stimulation of skin fibroblasts could be experimentally proven.

Lamii albi flos is used for catarrhal inflammation of the upper respiratory tract, for mild inflammation of the throat and oral mucosa, for mild non-specific dermatitis. The drug is commonly used (effect not proven) for unspecific fluorine albus.

For internal use, the daily dose is 3.0 g; for external use it is 5.0 g. Lamii albi flos is mostly used (according to Commission E) in the form of infusions or as a sitz bath (5.0 g on a sitz bath).
