Saponaria officinalis

It is a common host plant for some moth species, including the white-lined sphinx.

[6] Saponaria officinalis' native range extends throughout Europe, and in Asia to western Siberia.

It grows in cool places at low or moderate elevations under hedgerows and along the shoulders of roadways.

It has historically been used to clean delicate or unique textiles, especially woollen fabrics;[9] it has been hypothesized that the plant was used to treat the Shroud of Turin.

[10] A lathery liquid that has the ability to dissolve fats or grease can be procured by boiling the leaves or roots in water.

[citation needed][12] Despite its toxic potential, Saponaria officinalis finds culinary use as an emulsifier in the commercial preparation of tahini[13] and in brewing to create beer with a good head.

The plant is used to stabilize the oils in the mixture and to create the distinctive texture of halva.
