Perennial herb, 20-50cm high, native to Eurasia, naturalized in eastern North America; leaves triangular-ovate, minutely hispid, margin dentate; flowers white or yellowish-white.

The dried flowers (Lamii albi flos, Flores Lamii albi) are traditionally used as expectorant.

Alboside A and B are secoiridoids from Lumium album L. where they co-occur with lamalbid. They are derived from 8-epi-deoxyloganic acid. Caryoptoside is an intermediate in the biosynthesis of lamalbid and alboside B.

„Phytochemical study of the aqueous extract of the flowering tops of Lamium album led to identification of the antiviral iridoid isomers lamiridosins A and B (1, 2). These compounds were found to significantly inhibit hepatitis C virus entry (IC50 2.31 μM) in vitro. Studies of 14 iridoid analogues showed that, while the parent iridoid glucosides demonstrated no anti-HCV entry activity, the aglycones of shanzhiside methyl ester, loganin, loganic acid, geniposide, verbenalin, eurostoside, and picroside II exhibited significant anti-HCV entry and anti-infectivity activities.“
