Why does bartonella cause dry eyes and mouth?

Herbalist and doctors look at my tongue as it’s wilted and dried up and my body has been hot, burning all over skin which means in TCM that I’m overheated and drying out. So id like to understand the mechanisms as to why bartonella causes dry eyes and mouth, what is it affecting? What organ? I want to know the biological function of it, once I know them I can find a compatible herb to treat it.

I already have his books . All of them

He doesn’t say anything about it

Dr Bill Rawls takes Himilya OphthaCare Eye drops. I ordered then and they are definietley working. These are herbal eye drops

For dry mouth and dehydration....Lady of Lyme recommended ceralyte 50. I take that and it also works

Why we have these issues? I don't know. My dry moth and dehydration have gotten MUCH MUCH better. In fact, I rarely have to take ceralyte 50 anymore

The only thing I now do with 100% consistency is a NAC capsule, Kylolic Garlic 103. And the AIM GardenTrio. Which is a combination of AIM Barley Life, AIM Redibeets and AIM JustCarrots. I also take AIM Coco Leaf greens. Adding these juices and garlic supplements has been a game changer for me. I travel with them. Do not go a day without them

P.S. - just added Nutramedix Burbur-Pinella. Came highly recommended. Not sure what difference it has made yet, but all of my research convinced me I had to have it.
