Some of what is dismissed as "conspiracy theory" is simply a different opinion based on different, but valid, background knowledge. Doctors are generally NOT trained in herbology, nor do they keep up with the latest medical research for everything that might be relevant to all their patients. Doctors are required to keep up with pharmaceutical knowledge but they do not have time or particular incentive to keep up with research related to herbs, supplements and diet. So when we read blanket negative statements about non-drug remedies but we know better, because we have done our own research, we may view the propagandists with suspicion.
For example, below is research on concentrated elderberry juice that shows that elderberry does indeed have antiviral and immune-boosting effects, contrary to the article at LiveScience. Another, more recent study done in Australia had travelers take elderberry capsules or placebo before and during travel and then compared people in both groups who came down with colds. Elderberry reduced the severity of the symptoms and reduced recovery time by two days on average. Does that mean elderberry will stop you from getting coronavirus? Nobody has done that research yet. Should you take it? Why not? It's entirely up to you - not the government, YET, thank God!
"...We evaluated the antiviral effect of concentrated juice of elderberry (CJ-E) on the human influenza A virus (IFV). CJ-E had a relatively strong effect on IFV-infected mice, although its anti-IFV activity was weak in a cell culture system. The in vivo anti-IFV activities of the fractions were determined after separating CJ-E by ultrafiltration and anion-exchange chromatography. Oral administration of the high-molecular-weight fractions of CJ-E to IFV-infected mice suppressed viral replication in the bronchoalveolar lavage fluids (BALFs), and increased the level of the IFV-specific neutralizing antibody in the serum, as well as the level of secretory IgA in BALFs and feces. Fr. II from high-molecular-weight fraction HM, which contained acidic polysaccharides, showed relatively strong defense against IFV infection. We conclude that CJ-E had a beneficial effect by the stimulating immune response and preventing viral infection. "
While not a human study, humans have been taking elderberry for centuries to help with colds and flu. While they might have all been deluded, they also might NOT have been. Furthermore, elderberry has also been used in jams, preserves and drinks for centuries. Elderberry is food (unlike donuts or french fries... but I digress). There is no harm in taking elderberry. If it keeps you from getting really sick, you won't need to see the doctor. Quarantine yourself and no harm done. Don't go to work with a contagious disease whether it's coronavirus or something else. If you do get really sick, then go seek medical attention.
So how is elderberry a dangerous folk remedy, and dangerous to whom?
