With the growing global threat of the 2019 Novel Coronavirus (COVID-19), it's important to maintain an effective arsenal of antiviral protection to keep our hands clean and mitigate transmission, especially when in public environments where hand-washing facilities are not available or sanitary. A number of terpenes have shown promise in the literature in destroying viruses, and make ideal candidates for use in hand sanitisers to form a barrier of protection. Many also show antibacterial benefits to bolster their broad spectrum activities.
Many other natural compounds also show promise for systemic protection, such as the bioflavonoid hesperetin. Hesperetin has been demonstrated to inhibit the ability for the viral particles to self-assemble and therefore delays viral spread, giving the immune system more time to fight off potential infection before it occurs.
