God made nature for man and not the other way around. If they do not offer you natural remedies than they are using medicines as a remedy of which there is no science. These are toxic chemicals design against man's nature for if they were part of man's nature then they would be available by nature herself.
To be prove that these medications are not science give a handful of doctors a blind test. Write some test cases where they would normally prescribe medications such as
-
Patient is depressed that child died
-
Patient lashes and abusive at spouse
-
Patients like to cut themselves
-
Patient has delusions of Grandure
See what each doctor recommends and then realize it is all fabrications. The one's that give out the meds are the ones in need, as they think they are scientists, then realize that they suffer number 4; patient has delusions of grandure.
