Hands are the primary mode of transmission of microbe-based infections, as they harbor normal microbiota and pathogenic microbes. SARS-CoV-2 has endangered lives worldwide, and WHO has recommended good hygiene practices, especially hand hygiene. In addition, other infectious diseases like diphtheria, measles, tuberculosis, HIV, malaria, etc. are spreading in the shadow of the COVID-19 pandemic. The anti-microbial efficiency of two in-house developed herbal-alcohol based hand sanitizers containing Azadirachta indica, Citrus limon, Zingiber officinale, and Aloe vera (HS1) and Zingiber officinale replaced with Ocimum sanctum (HS2) was evaluated. HS1, with Zingiber officinale, and HS2, with Ocimum sanctum, herbal sanitizers showcased in-vitro anti-viral activity on MDCK cells using the reference strain of influenza A virus, A/PR/8/34 (H1N1), and reduced 99.99% of microbial load within 30 s of contact time, estimated by the Antimicrobial Susceptibility Testing Method. On volunteers, HS1 and HS2 were more effective than alcohol-based WHO sanitizers. Moreover, HS2 sanitizer is more effective against viruses and has better efficiency and hedonic qualities in volunteers than HS1. These sanitizers don’t irritate or dry up the skin and have a longer shelf life. Overall, findings reveal that herbal-alcohol-based sanitizers are promising hand hygiene products with the capability of reducing microbial load. [ABSTRACT FROM AUTHOR]
