Oregano Oil Antimicrobial Sensitivity Index (OOASI): A Basic Classification System for Assessing Oregano Oil's Efficacy Against Bacterial and Fungal Strains using 122 mcg Discs

The rising threat of antimicrobial resistance poses a grave challenge to modern medicine, necessitating urgent exploration of novel agents to combat infectious diseases. In this pursuit, natural compounds have emerged as promising candidates, with oregano oil standing out for its potential therapeutic benefits. However, to fully harness the antimicrobial prowess of oregano oil in clinical practice, the establishment of standardized susceptibility testing criteria is of utmost importance. Recognizing this critical need, the Oregano Oil Antimicrobial Sensitivity Index (OOASI) system was developed as a collaborative effort between the esteemed St. Patrick Institute of Medical Sciences (SPIMS) in Columbus, OH, USA, and the Clinical Laboratory RIDES in Santa Cruz, Bolivia. This pioneering endeavor marks a significant step towards filling the void in herbal antimicrobial classification and facilitating evidence-based therapeutic decisions.
