Micro-immunotherapy was developed by Dr Maurice Jenaer in the 1970s and is in wide use in Germany, France, Italy, Austria and other countries.
I'm from Germany and never heard of it before. The "wide use" is restricted to alternative practitioners here.
I find the text quite contradictory, as it says in the beginning "It can be used in any condition associated with acute or chronic inflammation which may be due to chronic infection with virus (not
bacteria or fungi)", but goes on to show which capsules to use in case of different bacterial infections.
[my bolding]
It also says "It is comprised of tiny doses, but
not homeopathic doses,(...)", but the manufacturer's text at the end talks about "homeopathic preparations". [again, my bolding]
So, nice colourful capsules, but I wouldn't throw my money on this.
