Our grandparents were of the belief that to rid the body of the bad required remedies that rid the body of those bad things. Cod Liver Oil, Muster plasters on your chest, Milk of magnesia, etc etc.
We survived so I can't say they were totally wrong. Maybe they were more right then we care to agree with.
Modern medicine seems to come with a lot of cautions, side effects etc. Here, take this for your kidney issues, but check with your doctor about side effects to your high Blood pressure or liver issues, etc, etc, etc.
We have no doctors that know us anymore. We are blood test and scans. No longer individuals with unique issues, makeup or physical differences. Therein lays the problem for us and for the doctors as well. We no longer connect.
Why, because business took over the medical business.
