Certain cannabinoid acids from hemp (Cannabis sativa) can prevent infection from the virus that causes COVID-19 by obstructing its entry into cells.
By binding to the spike protein, these acids can block the virus from reaching into cells and causing infection.
The study was published in the Journal of Natural Products. The research was led by Richard van Breemen, a researcher with Oregon State’s Global Hemp Innovation Center, College of Pharmacy and the Linus Pauling Institute.
“They are not controlled substances like THC, the psychoactive ingredient in marijuana, and have a good safety profile in humans,” van Breeman said, as quoted by local media. “Orally bioavailable and with a long history of safe human use, these cannabinoids, isolated or in hemp extracts, have the potential to prevent as well as treat infection by SARS-CoV-2,’ the researchers noted in the abstract of the study.
