Black walnut has traditionally been used most popularly for its antiparasitic properties in the intestines. For this reason, you will find it as an ingredient in various intestinal cleansing formulas.
It has various antimicrobial properties and has done well in studies with activity against both Lyme (Borrelia) and Bartonella.
It also has traditional use for helping to oxygenate the blood. It’s not a coincidence that some of the best herbal antimicrobials simultaneously help support healthy circulation and oxygen in the blood (think garlic, wormwood and black walnut)
A study done in 2020 focused on herbs effective against Borrelia burgdorferi and listed Cryptolepis, black walnut, Japanese knotweed, Artemisia (sweet wormwood), cat’s claw, Cistus incanus and Chinese skullcap as the most effective herbs that showed good activity against the stationary phase Borrelia burgdorferi compared to the control antibiotics doxycycline and cefuroxime.
Another study done in 2021 focused on herbs effective against Bartonella. Black walnut was found to be the most effective herb in that study and was even superior to several different antibiotic control groups.
