In September 2020 in the height of COVID-19 lockdowns a group of scientist decided to take a deep dive into herbal constituents and plant based medicine to see if there was any research on possible Covid-19 solutions. While this study was prior to the vaccines coming out, it warrants to report how important that some of these plants are for respiratory health and possible other SARS type viruses.
The article was then accepted and available in the Journal of Biocatalysts and Agricultural Biotechnology in December 2020 when talk of the first vaccines came out.
In this study, licorice was the winner in the antiviral, respiratory and SARS and Covid-19. The main compound glycyrrhizinic acid is where the main activity comes from. Other herbs such as Rosemary, Lemon Balm, Peppermint, Moringa, Oregano, Basil and Amla have studies with effective reduction of symptoms of different respiratory conditions and also different herpes illness.
While more research needs to be done to get more definitive answers, it is helpful to know that there are plants out there that can help through challenges, and plants that we can take in anticipation of getting sick or to make part of our daily lives to protect our immune system.
