"CBD helps reduce lung damage from COVID by increasing levels of protective peptide": 19-OCT-2020 Now they have shown that apelin levels go way down with the viral infection, which has killed 1 million people worldwide, and that CBD quickly helps normalize those levels along with lung function. "It was dramatic in both directions," says Dr. Babak Baban, DCG immunologist and associate dean for research, of shifting apelin levels in both circulating blood and lung tissue. Blood levels of the peptide dropped close to zero in their ARDS model and increased 20 times with CBD, they report in the Journal of Cellular and Molecular Medicine. "CBD almost brought it back to a normal level," Dr. Jack Yu, physician scientist and chief of pediatric plastic surgery at MCG, says of the apparent first connection between CBD and apelin. Apelin is a pervasive peptide made by cells in the heart, lung, brain, fat tissue and blood, and is an important regulator in bringing both blood pressure and inflammation down, says Baban, the study's corresponding author. https://www.eurekalert.org/pub_releases/2020-10/mcog-chr101620.php
