anti-microbials - either pharma or natural/herbs - are typically dependent on, and specific to the target organisms.
some are a bit broader targeting several of the common ones - like lyme and bartonella
for Lyme there are many prescript
ion and natural options
this LLMD has a pragmatic approach and some good and recommendations
https://www.treatlyme.net/guide/lyme-disease-antibiotic-guideif you are taking other medications - esp for something critical - like a heart condition
it would be wise to consult doctor on potential drug / herb interactions
i understand this can be difficult to access in many countries - but many LLMD's or Integrative doctors will do remote consultations via video/skype/zoom these days
or at the very least use an online interaction tracker to check for any interactions
(be aware that all herb interactions or even suspected interactions on such sites are generally assumed to be negative - but will at least serve to highlight a potential risk to be investigated).
by the way - heart conditions can be caused by lyme - and/or bartonella - eh valve vegetations or calcification, myocarditis, pericarditis, endocarditis, arrhythmias, angina, unexplained pain etc etc) and may be worth investigating from that angle as they can resolve entirely after proper treatment.
both bartonella and lyme also cause damage to the cells that line the blood vessels and can cause high blood pressure as a result and also cause clotting disorders due to the coagulation mechanisms becoming triggered or dysregulated by the inflammation they cause.
finally while the focus of this thread, and the article linked, is active treatment - most people with chronic lyme really need a comprehensive approach that includes diet and lifestyle optimisation - with sleep, diet, stress levels, social/ emotional support, exercise - etc in order to progress. only a few just take pills, herbs or supplements and recover.
