This interesting comment stood out to me: "Lung damage is a major hurdle to recovery in those severe patients. Through producing various growth factors, MSCs may help repair of the damaged lung tissue. It is important to mention that various studies have shown that in animal models with bleomycin-induced lung injury, vitamin B3 (niacin or nicotinamide) is highly effective in preventing lung tissue damage . It might be a wise approach to supply this food supplement to the COVID-19 patients."
This article was written in the context of COVID-19: "False information can spread like wildfire, particularly during times of fear and uncertainty. Right now, there is misinformation circulating about elderberry (Sambucus nigra) and COVID-19.
Elderberry extract is being falsely accused of triggering a cytokine storm or cytokine release syndrome (CRS), an intense inflammatory response that can be deadly. During the SARS epidemic, CRS caused severe lung damage and was a driving factor in many fatalities."
