Scientific and medical research over the past two decades show that, individually and in combination, essential oils such as basil, citrus, mānuka, mint, rosemary, oregano, tea tree and thyme are a source of safe, highly effective and renewable antimicrobials for use in human and animal therapeutics and hygiene products such as hand and surface sanitisation. They have rich chemical diversity and few side effects compared to synthetic chemicals. Furthermore, plant essential oils do not give rise to Antimicrobial resistance (AMR).
