Starting herbal coinfection treatment

sounds bart like to me - but as you say - always hard to rue out babs

your current combo is a good basic starter for helping the inflammation and immune system - without being strong killing herbs - so should be relatively easy to take and form a good basis

this is v similar to what i did to get started - mainly used the anti-inflammatory and immune regulating buhner lyme herbs first - then gradually added the more anti-microbial co-infection herbs

salvia militorhiza / red sage root - is another of those general immune function herbs that Buhner recommends for all of these infections in his later books - i think its a good one

the on the anti-microbials - Cryptolepis and sida acuta both have activity for bart and Cryptolepis
houttuynia for bart also

oil of oregano is another good option for Bart - and Babs and Lyme - so very broad - but not everyone tolerates it well

in terms of resources for herbal approaches

Buhner's books - particularly his
"Healing Lyme - 2nd edition" is about the best out there
https://www.amazon.co.uk/healing-lyme-borreliosis-coinfections-rickettsiosis/dp/0970869649

there is also this website - which is older - and not maintained by him for the last 10 years of so - but has useful resources
