The allopathic drugs companies has no antiobitic, anti-viral, anti-fungal, anti-parasitic etc that can compete or that even comes close to what turpentine can do to kill such a wide range of pathogen species. And because of the way turpentine kills these pathogens(very fast) -- pathogens cannot adjust to it like bacteria can adjust to antibiotics.
Little wonder then that the drugs companies banned turpentine...their drugs just coudn't compete with turpentine's anti-pathogenic capabilities. So they just banned it and everybody believed their corrupt reasons despite the fact that turpentine had already been used internally -- quite safely and effectively -- for thousands of years.
