Resistance to antibiotics continues to rise and few new therapies are on the horizon. Honey has good antibacterial activity against numerous microorganisms of many different genera and no honey-resistant phenotypes have yet emerged. The mechanisms of antimicrobial activity are just beginning to be understood; however, it is apparent that these are diverse and often specific for certain groups or even species of bacteria. Manuka honey has been most thoroughly characterized and is commercially available as a topical medical treatment for wound infections. Furthermore, since most data are available for this honey, there is a considerable focus on it in this review. It is becoming evident that honeys are more than just bactericidal, as they impact on biofilm formation, quorum sensing and the expression of virulence factors. With this in mind, honey represents an attractive antimicrobial treatment that might have the potential to be used alongside current therapies as a prophylactic or to treat wound infection with multidrug-resistant bacteria in future.

Deep cutaneous wounds, which are difficult to heal and specifically occur on dynamic body surfaces, remain a substantial healthcare challenge in clinical practice because of multiple underlying factors, including excessive reactive oxygen species, potential bacterial infection, and extensive degradation of the extracellular matrix (ECM) which further leads to the progressive deterioration of the wound microenvironment. Any available individual wound therapy, such as antibiotic-loaded cotton gauze, cannot address all these issues. Engineering an advanced multifunctional wound dressing is the current need to promote the overall healing process of such wounds.

Honey is a valuable natural product with antioxidant properties, and its quality is influenced by various factors, including botanical origin and biofortification. Pine bud extracts, known for their antioxidant capacity, were explored to enhance the properties of acacia and polyflower honey. This study aimed to investigate the effect of pine bud extracts at different maturation stages on the moisture content, dry matter, antioxidant activity, and total phenolic content (TPC) of acacia and polyflower honey.

Background: It seems that some substances of plant origin may exert health-promoting activities in diabetes and its complications, including those concerning bones. Chrysin (5,7-dihydroxyflavone), present in honey, some plants, and food of plant origin, has been reported to exert, among others, antioxidative, anti-inflammatory and antidiabetic effects. The aim of this study was to investigate the effects of chrysin on the skeletal system of rats with experimental type 1 diabetes (T1D).
