CBD Mouthwash Could Prevent Covid-19 Infections

Hello has a line of CBD mouthwash products. Start using them right away to protect from being infected by the coronavirus.

CBD, the miracle worker cannabinoid, is being hyped as a preventative for Covid-19.

A Canadian study using a human 3D tissue model contends that cannabis "may become a useful addition to the treatment of Covid-19 and an excellent GRAS adjunct therapy." (GRAS stands for generally recognized as safe.)

Initially reported on by the Calgary Herald on May 7, the story was picked up this week by the New York Post, Merry Jane and other media outlets.

Based on research conducted at the University of Lethbridge in Calgary, Dr. Igor Kovalchuk says his team determined that several high-CBD strains "reduced the number of (virus) receptors by 73%. If they can reduce the number of receptors, there’s much less chance of getting infected.”

Dr. Mary Clifton: "If you have a CBD elixir, chances are you can start to benefit from this protection right away."

Kovalchuk was referring to CB2 receptors, which CBD binds to. They're "found mainly on immune cells, including the liver and spleen and bone marrow," according to New York cannabis specialist Dr. Mary Clifton. "Immune resilience could potentially be enhanced by changing the number of CB receptors or increasing the presence of the cannabinoids to stimulate those receptors."

Clifton tells CelebStoner: "Cannabis and CBD may reduce cytokines production, a key factor in inflammatory responses to infection. Cannabis and CBD may not only reduce the intensity of infection, but also may block infection from happening in the first place."

It might be a simple as gargling with a CBD-infused mouthwash to prevent the Covid infection from spreading. "[Cannabis] may also be used to develop easy-to-use preventative strategies such as mouthwash and throat gargle products that may be tested for their potential to decrease viral entry via the oral cavity and may be used both in clinical practice and at-home treatment," the Health Canada-funded study concludes.

Clifton agrees: "If you have a CBD elixir, chances are you can start to benefit from this protection right away by taking usual doses on a regular basis during the pandemic."

There are several CBD mouthwashes on the market, including CBD Elixir, ORL Labs CBD Mouthwash, Hello and Carun.
