>It's probably time we start looking a bit harder for "natural" or alternate treatments. Some in medical journals, are under scrutiny, but inconclusive.

We are looking, quite hard, in fact. Mycobacterium tuberculosis is among the most studied microörganisms.

Like HIV, it is notable particularly for being able to defeat the attempts of the immune system cells to kill it, and it in fact infects and reproduces within macrophages. Medical researchers have done a lot to understand how this is possible and we (as in humanity) have identified several enzymes and related biomolecules which seem to be crucial to this process, which we might be able to inhibit with a targeted drug.

However, all of this scientific research has the usual problem that it is very difficult and expensive. In order to inhibit the enzyme, the drug must be absorbed by the body, and then make its way into the macrophages, and then it still must be active, and have no other toxicity to the host. It is easy to say "just inhibit isotuberculosinol synthase", but it is much harder to do.

As I understand it, this is also the reason why treating tuberculosis requires such long courses of antibiotics. When treating a normal infection, we are basically just killing most of the pathogens, and we hope that the immune system will mop up the rest. In the case of M. tuberculosis, the drugs have to kill all of the bacteria, which is why multidrug therapy is basically always used and the patient must continue treatment long after symptoms seem to have disappeared. Even when patients have recovered, they are always considered to be at risk of still having latent tuberculosis, which is why hospital screenings often feature a question like "have you ever had a positive test for tuberculosis?"

This - TB is very well studied compared to most infectious diseases. I think really only HIV and Malaria edge it out.
Not to say that it's always the case, but research isn't always at face value - i.e., sometimes there's circularity, economical or political dynamics, etc, that perpetuate dead ends while neglecting more viable avenues.

An example might be enzymes (notably in cancer research), where in the US there has been significantly less pursuit than elsewhere. To avoid attacks, I'll cite a source[0] which readers can maim rather than my comment.

In some pirtions of this book, entities other than pinata boy on HN, express concern regarding the quality, fairness or whatever's of research, with indications that 'research' may not always be equally noble or pragmatically guided. I suspect it's one of many where that particular subject is grazed upon. But my point is, if not overemphasized, that there may be quantity over quality issues, with viable options hiding in plain sight.
