Ginseng and Salviae herbs play a role as immune activators and modulate immune responses during influenza virus infection
What some people may not be aware of is that, in many vaccinations, drug companies use what’s called an adjuvant to strengthen the body’s immune response. Aluminum is a component of many of these adjuvants. While it would seem like an inherently bad idea to inject a toxic metal directly into the human body, that is exactly what they do to stimulate a stronger response. So, while I am against the idea of forcing an immune response in a route of administration other then what Mother Nature intended, natural compounds might be a better route to try.
This study used ginseng and salviae as part of an intranasal injection (which is a natural route of exposure) and found that it may make a good adjuvant for this flu vaccine.
