Assessing the antimicrobial activity of flaxseed

Share:

Researchers in India evaluated the antimicrobial activity of flaxseed against known periodontal pathogens. They reported their findings in an article published in the International Journal of Herbal Medicine.

  • Research suggests that the use of antibiotics is beneficial in the management of periodontitis.
  • However, antibiotic resistance has now become a major global issue, and it is believed to have stemmed from the misuse of antibiotics.
  • Many researchers now see herbal interventions as therapeutic strategies that deserve more research and attention.
  • Flaxseed, a popular superfood rich in omega-3 fatty acids, has demonstrated potent antimicrobial and anti-biofilm activities in several studies.
  • To further explore its potential, the researchers conducted an in vitro study that aims to assess the antimicrobial activity of flaxseed against periodontal pathogens.
  • They prepared an ethanolic extract from flaxseed powder and determined its minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) against Porphyromonas gingivalis, Aggregatibacter actinomycetemcomitans and Tannerella forsythia.
  • The researchers reported that the flaxseed extract exhibited bacteriostatic activities against all three pathogens.
  • At 100 microliters (uL)/milliliter (mL), the extract exerted bactericidal effects against P. gingivalis.

Based on these findings, the researchers concluded that flaxseed can be used as a natural adjunct to periodontal therapy because of its bactericidal effects against P. gingivalis.
