Panax ginseng is good when Pseudomonas a. is found. That bacteria is hard to get rid of, because it creates a biofilm and encapsules it, so the body's immune system can't reach it. Panax ginseng unwraps and prevents that "encapsuling" process.
I also think that spirulina has a similar effect. A peculiar thing is, that birds are given spirulina as a supplement to prevent them from getting Pseudomonas....
our daugther is 5 and has had pseudomonas twice during her first 2 years. But now they only find bacteriae like haemophilus influenza, staphyloccocus aureaus and the like.
