Under the current conditions of growing antibiotic resistance of microorganisms, studies of antimicrobial properties of natural substances, including those obtained from medicinal plants, acquire special interest. The future outlook of such studies is caused by the fact that the resistance of microorganisms to vegetable-based substances may develop much slower or may not develop at all. This work is devoted to investigation into antimicrobial, antibiofilm-forming and some phytochemical properties of Equisetum arvense L. extracts. The results of the study showed high antibiofilm-forming activity of Equisetum arvense L. extracts exemplified by staphylococcus biofilm. Antimicrobial properties of the reviewed extracts were also ascertained. Antibacterial activity was identified against typical and clinical antibiotic-resistant bacterial strains isolated from the mouth cavity of patients suffering from inflammatory processes. High antioxidant activity of the extracts was shown. A set of properties, in particular the antimicrobial and antibiofilm-forming activity, high content of tannins and antioxidant activity, shows good prospects to include horsetail (equisetum) extracts in the oral cavity care plan.
