Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Lithospermum erythrorhizon, also known as "purple gromwell" or "zi cao" in traditional Chinese medicine, has a long history of use for various skin disorders, including eczema. Its root contains shikonin and related naphthoquinone derivatives, which are believed to have anti-inflammatory, antimicrobial, and wound-healing properties. In traditional East Asian medicine, ointments or creams containing extracts of this plant have been applied topically to soothe inflamed skin, reduce itching, and promote healing in cases of eczema and other dermatological conditions.

However, scientific validation for its effectiveness in treating eczema specifically is limited. Most of the supporting evidence comes from in vitro or animal studies demonstrating anti-inflammatory and antimicrobial effects of shikonin and its derivatives on skin cells and in models of dermatitis. There are a few small-scale clinical studies and case reports, but these are generally low quality and not specific to eczema; often, they include other inflammatory or infectious skin diseases.

Overall, the use of Lithospermum erythrorhizon for eczema is primarily justified by traditional practice and historical anecdotal evidence, with some preliminary scientific rationale but insufficient robust clinical data to strongly support its efficacy or safety for this condition.
