Buhner Bartonella protocol and prescription meds

most herbs will have some effect on prescription medications to some degree

the issue is they both tend to use the same metabolic pathways in the body to process and excrete them

the body has to do this with all foreign substances in order to not accumulate them over time.

some herbs are known to do this more than others - but in truth, not all interactions between even common pharmaceutical drugs and other pharmaceutical drugs are known - and even less is generally spent on herb/drug interactions as there is less financial incentive for drug companies to do so.
it's actually a recognized problem in medicine where something like 50% of our over 60's population is on 4 or more concurrent medications - and around 50% of us also take various supplements and the interactions of all of these various combinations are not fully mapped out.

there are also large individual differences in the activity of these metabolic pathways from person to person - due to genetic differences - microbiome differences - diet amongst other factors.
this is one of the reasons drugs that trials show work on average across 1000 people - often do not work at all for an individual. So no one can really reliably tell in advance which will do what for a person - best you can do is to look for possible or likely trends to look for.

the main pathways concerned are in the liver - these are known as the Cytochrome system - or detoxification pathways - of the herbs on your list - Chinese skullcap is known to be an inhibitor of one of the main ones - CYP 450 - and typically slows down excretion of most drugs using this pathway and may cause their blood levels to rise and effects to be magnified ( this is actually why it is used in TCM as a potentiator for other herbs in combinations).

there are online resources that attempt to shed some light on these interactions -

eg. https://reference.medscape.com/drug-interactionchecker

but as a user, you need to bear in mind the inherent assumptions and paradigms of the people who create such things.
typically they are from a western medicine leaning and do not understand herbs or their actions in the body at all well - for this reason, they tend to regard all herbs as potentially dangerous self-medication, portray any interactions as a bad thing, and view any uncertainty around their actions as high risk - whereas they tend to view similar uncertainties around pharmaceutical drugs as benign and acceptable.

if you spoke to a herbalist or a functional medicine practitioner you would likely receive the opposite view.

if it were me i would take note of the general likely effects, be vigilant of the possible effects and tread carefully when using herbs and prescription meds together. eg use small doses initially and step up v slowly over weeks
