Gentian violet

What is gentian violet?

Gentian violet is an antiseptic dye that has been used since 1890. The name comes from its color, it is not made from gentian or violet flowers.

Gentian violet has antifungal and antibacterial activity and has traditionally been used as current treatment for a variety of dermatological conditions. However, there is little evidence from clinical trials to support its long-term effectiveness or safety, so for many diseases, more modern treatments, such as antibiotics and others systemic medications, are favored. In many countries, gentian violet is no longer available for medical purposes.

Gentian violet uses

Gentian violet has been used to treat the following dermatological conditions:

  • Infecciones fúngicas, incluyendo infecciones fúngicas de la piel, candidiasis oral (candidiasis oral) and vulvovaginal candidiasis (vaginal yeast infection). More recently, gentian violet has been used to treat oral candidiasis in patients who are HIV-positive.
  • Superficial bacterial infections of the skin as infected eczema, boil and chronic leg (long-standing) ulcers. Gentian violet may also be active against resistant methicillin Staphylococcus aureus (MRSA)
  • Leucoplasia vellosa oral (blanca plates on the edges of the tongue). This condition occurs in patients with weakened immune systems, particularly HIV positive individuals. Oral hairy leukoplakia is associated with Epstein Barr virus (EBV), the cause of glandular fever. EBV infection results in the generation of reactive oxygen species; Gentian violet is believed to work by inhibiting reactive oxygen species.

Gentian violet has also been used for other medical and industrial purposes.
