CBD appears to reduce the "cytokine storm"

CBD helps reduce lung damage from COVID

One way CBD appears to reduce the "cytokine storm" that damages the lungs and kills many patients with COVID-19 is by enabling an increase in levels of a natural peptide called apelin, which is known to reduce inflammation and whose levels are dramatically reduced in the face of this storm.

They reported this summer in the journal Cannabis and Cannabinoid Research that treatment with CBD reduced excessive lung inflammation, enabling improvements in lung function, heathier oxygen levels, and repair of some of the structural damage to the lungs that are classic with ARDS. The investigators said then more work was needed, including finding how CBD produced the significant changes as well as human trials, before it should be included as part of a treatment regimen for COVID-19.

Now they have correlated those improvements with regulation of apelin. While they don't attribute all CBD's benefits to apelin, they say the peptide clearly has an important role in this scenario. They also don't yet know whether the novel coronavirus, or CBD for that matter, have a direct effect on apelin, or if these are downstream consequences, but they are already pursuing answers to those unknowns.
