Galangin is a flavonoid compound found predominantly in the rhizomes of Alpinia officinarum (lesser galangal) and in propolis. It has been traditionally used in herbal medicine, but there is also scientific research evaluating its antibacterial properties. Several in vitro studies have demonstrated that galangin exhibits antibacterial activity against a range of Gram-positive bacteria, including Staphylococcus aureus and methicillin-resistant S. aureus (MRSA). Proposed mechanisms include disruption of bacterial cell walls, inhibition of nucleic acid synthesis, and interference with key enzymes involved in bacterial metabolism.

However, the evidence remains at a preclinical level. Most studies have been performed in laboratory settings using isolated bacterial cultures, and there is a lack of well-designed animal studies or human clinical trials investigating its efficacy or safety for treating bacterial infections. Therefore, while scientific interest and early data exist, there is insufficient high-quality clinical evidence to support its use as a primary or adjunctive antibacterial agent in humans. In summary, galangin displays promising antibacterial activity in vitro, but further research is necessary to validate its effectiveness and safety in clinical scenarios.
