In the literature over the past few years there has been studies discussing the chemotherapy drugs having activity against some strains of bacteria Different classes of chemotherapy drugs have shown activity against 4 pathogenic microorganisms. Some of these chemo drugs are the anti metabolites, mitomycin C , 5 FU , methotrexate and many more.
When I look at anti microbial herbs I have found that many of these which address bacteria, fungi and viruses and even spirochetes ( like in Lyme disease) also exhibit anti tumor activity, making them effective in the treatment for cancer and multiple systemic chronic infectious syndrome ( MSCIS)
So chemo drugs can kill bacteria yet herbs with anti bacterial activity also can and do have anti tumor activity
I prefer herbs
This correlation needs to be looked at more in future studies.
