The rhizome is reddish, creeping, strongly branched, up to 1 cm thick, slightly knotty, with numerous cylindrical, bearded roots. The stems are usually many, upright or upright, cylindrical, knee-high up to 1 m tall, slightly branched, bare or slightly fluffy at the top. The leaves are cross-cut, short-stemmed, smooth and sharp with 3 veins. The upper leaves are seated. The flowers are bipolar, slightly aromatic, large, white or pale pink, gathered 3-7 at the top of the stem or on the leaves of the leaves of the leaves, forming loose or frayed petals. Blooms in the summer. The whole plant is naked or slightly hairy.

It is found in the shrubs, in wet places, in the sands along the larger rivers up to 1000 m above sea level.

Rhizoma Saponariae of the older plant and the flowering herb (Herba Saponariae) of the curative soap are used. Picking up in March-April or September-November. Dredge the roots before the blooms start. Picking of overhead parts takes place during flowering by cutting the stems about 30 cm from top to bottom. The leaves of the uncut portion of the leaves are also leavened.
