When I first came out with The Food and Supplement Guide for the Coronavirus (newly revised and released as Version 5.0 this week), many people questioned my recommendation to use elderberry extract as first-line defense against the coronavirus (after the critical hygiene and social distancing recommendations made by all the public health experts). They worried that elderberry could contribute to the “cytokine storm” seen in COVID-19, a condition where the immune system responds strongly and dysfunctionally to the virus, causing damage to multiple organs and potentially causing death.
