Regarding Zalmanov's theory - the common
reason of depression, weariness and lot of
other illnesses is metabolism disorder,
especially for people older 40-45.
To remove this illness you have to
renew/restore your body metabolism
mechanism.
Zalmanov invented special
emulsions(1950-1955) and used them to cure
people. His method was proven and accepted
by French Ministry of Health.
Believe me or not, but I use Zalmanov
emulsions myself and they work perfect.
