Haokang Xu1, Ian Edwin Cock1,2,*1School of Environment and Science, Griffith University, Brisbane, AUSTRALIA.2Centre for Planetary Health and Food Security, Griffith University, Brisbane, AUSTRALIA. DOI: 10.5530/pc.2024.2.10 ABSTRACT Background: Terminalia ferdinandiana Exell. is an endemic Australian plant with a high anti-oxidant capacity. Liquid solvent extractions of T. ferdinandiana leaves are strong inhibitors of the growth of numerous bacterial pathogens. Despite these promising therapeutic properties, methods for the rapid extraction of large quantities of T. ferdinandiana leaves are lacking. This study aimed to develop a rapid supercritical extraction method to produce extracts which retain therapeutic properties and phytochemistry characteristics. Materials and Methods: Terminalia…

Ian Edwin Cock1,2,*, Michael Whitehouse21Centre for Planetary Health and Food Security, Griffith University, Nathan, AUSTRALIA.2School of Environment and Science, Griffith University, Nathan, AUSTRALIA. DOI: 10.5530/pc.2024.2.11 ABSTRACT Introduction: Nanotechnology is promising for the development of new effective medicines. Silver nanoparticle preparations have been particularly well studied and a range of beneficial effects have been identified. Despite this, the sale of Colloidal silver (CS) preparations for therapeutic purposes has been banned by multiple regulatory authorities (including the FDA and TGA) on the basis of their perceived toxicity. This study evaluates the toxicity of electrolytically produced (CS) preparation, as well as some compounds…

DOI: 10.5530/pc.2024.2.13 In the aftermath of the height of the SARS-CoV-2 viral pandemic that resulted in considerable mortality and brought the world to a standstill for several years, epidemiologists and virologists are concerned about the next pandemic. Whilst the effects of COVID-19 are still being felt globally (especially by those experiencing ‘long COVID’) the focus of many researchers and clinicians has now turned to predicting when and where the next pandemic will…

DOI: 10.5530/pc.2024.1.2 ABSTRACT As old as humanity itself, medicinal plants have been used to treat illnesses. The use of medicinal herbs has not decreased despite any scientific advancement. The history of the relationship between mankind and the search for drugs predates now. There used to be a dearth of information regarding therapeutic plants, but his search never came to an end. Man’s long-running battles with disease prompted…

DOI:10.5530/pc.2024.1.4 ABSTRACT Introduction: An increase in antibiotic resistance and a corresponding decrease in antimicrobial discovery have directed researchers towards alternative therapies, including plant-based medicines. However, synergistic combinations of plant extracts with conventional antibiotics may be a far more effective approach in overcoming resistance and potentiating the activity of antibiotics that are otherwise ineffective against resistant bacterial strains.
