Re: Herbal resistance true?
Rotation could help but the first thing is to find what the organisms are sensitive to. There are classes of treatments for example there are many anti protozoa agents, same with herbals. If you are not sure what you have then you have to test in classes of treatments until you find a hit.
"Also, when a substance is "resisted" and then exposure is stopped for a length of time, and then exposure is started again, is the infection vulnerable to treatment again?"
It could I suppose but I have found that not true in my case. Technically if the organism has resistance properties (which not all do) then the chemical is marked so redosing has not been effective until you bind the efflux pumps up. This has proven true in my case and others that I have talked to.
If you rotate (or use more weapons), you increase the chance of success. When I have become sick with a new bug, I scatter the treatments (take more things) to improve my probabilities that I will stumble on the right remedy. I would never rely on a single remedy to give me the miracle cure although raw garlic and black seed would be good choices since they have a wide range of effectiveness.
