DESCALZO-CASADO, Elena  e  SIERRA-SANTOS, Lucía. Chemical burn by Sanguinaria canadensis. Rev Clin Med Fam [online]. 2022, vol.15, n.2, pp.116-118.  Epub 19-Set-2022. ISSN 2386-8201.

Sanguinaria canadensis, or Bloodroot, is a plant native to North America, which contains alkaloid substances. It is widely used in the treatment of skin lesions and tumours in animals. However, over the past few years its use in humans has increased as an alternative therapy treatment for precancerous lesions and skin cancer. Its inappropriate use in humans can cause severe and deep skin wounds.

We report the case of a young patient who willingly applied an extract of Sanguinaria canadensis (‘Bloodroot paste’) to remove two cutaneous nevi. This led to extensive wounds that required treatment and cures until they closed by second intention healing. Hypertrophic scars were left as sequelae.

Palavras-chave : Sanguinaria; skin ulcer; penetrating wounds.
