Drugstores sell useful medicines that are not endorsed by FDA however popular among people. One Russian blogger visited the factory which makes such medicines. How are they made? Very simple. They take ordinary stumps (they remain after deforestation and are absolutely unneeded but still not thrown away) and apparatuses resembling moonshine stills. These stumps are cut into pieces and placed into those apparatuses to be converted into very useful powder which becomes a must have thanks to some marketing manipulations.
