Its naturally purple-colored naphthoquinone compounds (including shikonin) give the extract a distinctive color and have made it a notable ingredient in specialty skincare.

What it is
Lithospermum erythrorhizon root extract is produced by extraction of Lithospermum erythrorhizon roots. The extract contains shikonin and related naphthoquinones — compounds responsible for the distinctive purple-red color — along with tannins and other polyphenols.
Typical uses in Japanese products
In cosmetics, shikon extract appears in skincare specialty products, particularly ones positioning around Japanese traditional-medicine heritage. The natural purple color is sometimes a deliberate design element.
In traditional healing practice, Shiun-kō and related salves are applied to minor skin issues. These uses are separately regulated as Kampo preparations when claimed for medicinal purposes.
