Cannabis compounds prevented the virus that causes Covid-19 from penetrating entering human cells, according to a laboratory study published in the Journal of Nature Products.
The two compounds commonly found in hemp -- cannabigerolic acid, or CBGA, and cannabidiolic acid, or CBDA -- were identified during a chemical screening effort as having potential to combat covid, researchers from Oregon State University said. In the study, they bound to spike proteins found on the virus and blocked a step the pathogen uses to infect people.
The researchers tested the compounds’ effect against alpha and beta variants of the virus in a laboratory. The study didn’t involve giving the supplements to people or comparing infection rates in those who use the compounds to those who don’t.
Hemp is a source of fiber, food and animal feed, and extracts are commonly added to cosmetics, body lotions, dietary supplements and food.
