What is Gromwell Root Extract Powder?
Gromwell Root Extract Powder is derived from the roots of Lithospermum erythrorhizon, a traditional botanical known for its high content of naphthoquinone compounds, particularly shikonin and its derivatives.
This extract is widely used in cosmetic formulations, functional skincare, and herbal applications, valued for its antioxidant, skin-conditioning, and bioactive properties.
Our extract is produced using advanced extraction and purification processes to ensure consistent active content, color stability, and batch uniformity.
