Alpha-terpineol is a naturally occurring monoterpene alcohol found in many essential oils, including those of pine, cajeput, and eucalyptus. Its use in supporting or treating infections has some scientific basis, primarily from in vitro (laboratory) studies demonstrating antimicrobial activity. Research has shown that alpha-terpineol exhibits inhibitory effects against a range of bacteria, including Staphylococcus aureus, Escherichia coli, and some fungi such as Candida albicans. These effects are attributed to its ability to disrupt microbial cell membranes, leading to cell lysis and death.

Despite these findings, the evidence is largely preclinical and limited to laboratory settings. There are few, if any, robust clinical trials evaluating the efficacy and safety of alpha-terpineol in treating human infections. Most uses in aromatherapy or herbal medicine are extrapolated from laboratory data and not from human clinical outcomes. While the compound shows promise as an antimicrobial agent, its practical application in treating infections in humans remains unproven and under-researched. Therefore, while there is scientific rationale for its antimicrobial potential, the current evidence for clinical use is weak and warrants further investigation.
