Some of the meds are quite toxic to the liver and have serious side effects. People take them because the alternative is death.
Well, what is it that they used to do, for tuberculosis?
Tuberculosis of course was a major killer during the last half of the nineteenth century, into the first half of the twentieth; in fact, I do believe it was the leading cause of death some years.
This was all before my own time, but as a little kid, since the parents were in the hospital business, whenever we went places (South Dakota, Michigan, Pennsylvania, and somesuch), once in a while we came across very large buildings, which must've housed hundreds, that by then were vacant, their windows boarded up.
These were not slum areas, but usually buildings in a remote rustic pastoral area.
It was explained to me that these had been tuberculosis hospitals, but they weren't needed any more.
One of my grandmothers as a very young girl, contacted tuberculosis and was sent to a spa, or resort, where each tuberculosis patient lived in his or her own little private cottage, or at most shared it with one other patient--in a remote rustic but peacefully pastoral area of northwestern Pennsylvania. She was there for eight years, and recovered, living to an old age.
One of my aunts shortly after becoming a registered nurse, contacted tuberculosis, and was "sent away" to somewhere in New Jersey. This was the mid- to late-1940s. She was there for two years, and recovered, living to an old age.
Perhaps there are non-pharmaceutical means to cure tuberculosis? I dunno, I'm honestly ignorant about the matter.
