I've learned the hard way to believe only my research and tests,
because unfortunately in every demanding professions we have scarcity of qualification and honesty.
Doesn't matter MD or natural practitioner, both can screw you up if you did not educate yourself. 99% percent of MD are just there only for the money, they don't understand how human body works at all and they're not even interested in knowing. That is really scary. They always try to fix symptoms not the cause and with the worse possible way, with drugs. They fail to abide by the most important principal in medicine: "Primum non nocere" (first do not harm) and keep the Hippocratic Oath.
