Moderate

Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.

Madder root from Rubia tinctorum supplies anthraquinone dyes including alizarin and lucidin; lucidin's documented genotoxicity has led to restrictions on internal madder use and warrants caution topically.

Skin benefits

  • Natural anthraquinone colorant
  • Traditional skin uses

Known concerns

  • Lucidin is genotoxic and mutagenic
  • Alizarin and related anthraquinones flagged in EU and Germany
  • Internal use of madder banned in several jurisdictions
