This is one of the articles I came across. Are these guys legitimate? https://www.thelunghealthinstitute.com/blog/marijuana-and-copd-medical-professionals-are-still-unsure. Are these claims science based? Another alternative treatment we offer is cellular therapy. Cellular therapy is a minimally invasive procedure that uses concentrated platelets and cells from your body to target lung disease. These platelets release healing properties that, when combined with proteins, growth factors and other helpful cells, may promote healing in damaged tissue and reduce inflammation in your lungs.
