(Natural News) Researchers at Teikyo University in Japan investigated the effects of Damask rose (Rosa damascena) water on the growth of Candida albicans and methicillin-resistant Staphylococcus aureus (MRSA) and on the function of neutrophils, which are key regulators of inflammatory reactions. They reported their findings in an article published in Biological and Pharmaceutical Bulletin.

  • Hydrosol prepared from the flowers of R. damascena is traditionally used to treat various health issues, including skin conditions like erythema, itchiness and swelling.
  • To treat skin problems caused by microbial infections, agents with antimicrobial and anti-inflammatory properties are important.
  • The researchers tested Damask rose water on C. albicans and MRSA, which commonly causes skin infections, and assessed its effects on neutrophil adhesion response.
  • They reported that rose water (2.2. percent solution) inhibited mycelial growth of C. albicans and reduced the viability of MRSA within an hour of treatment.
  • Damask rose water (five to 15 percent) also suppressed neutrophil activation induced by lipopolysaccharide (LPS), tumor necrosis factor alpha (TNF-a) and N-formyl-Met-Leu-Phe (fMLP).
  • Additionally, Damask rose water reduced LPS- and TNF-a-induced cell surface expression of the adhesion-related molecule, cluster of differentiation (CD) 11b but did not affect the migratory capacity of neutrophils (with or without a chemoattractant).

Based on these findings, the researchers concluded that Damask rose water can reduce the pathogenicity of microbes and attenuate neutrophil stimulation, thus inhibiting skin inflammation caused by microbial infections.
