Evidence—not promises
Herbs studied against tick-associated organisms.
A peer-reviewed botanical experiment can show whether a plant extract or compound affected an organism under specific laboratory or animal conditions. It cannot by itself establish that the product treats a human infection. Each entry below is labeled by evidence level.
Lyme / Borrelia burgdorferi
| Botanical | What the study found | Evidence level | Study |
|---|---|---|---|
| Cryptolepis sanguinolenta | Strong activity against growing and stationary-phase cultures; 1% extract produced no regrowth in the study's subculture experiment. | In vitro | Johns Hopkins–affiliated study ↗ |
| Japanese knotweed | Among the most active botanicals against growing B. burgdorferi in the same screening study; stationary-phase activity was also reported. | In vitro | Feng et al. ↗ |
| Black walnut | Activity was reported against stationary-phase culture at tested extract concentrations. | In vitro | Feng et al. ↗ |
| Sweet wormwood / Artemisia annua | Showed activity against stationary-phase B. burgdorferi in vitro, but in-vitro activity does not establish human efficacy. | In vitro | Feng et al. ↗ |
| Cat's claw | Reported stationary-phase activity in the screening study; a later clinical review emphasized that human trials are lacking. | In vitro | University of Maryland review ↗ |
| Chinese skullcap | In-vitro anti-borrelial activity was reported; clinical efficacy and appropriate dosing for Lyme disease have not been established. | In vitro | Review ↗ |
A useful negative result: the same study reported little or no stationary-phase activity for Stevia, Andrographis, grapefruit-seed extract, colloidal silver and monolaurin under the tested conditions. “Natural” does not automatically mean antimicrobial.
Babesia
The Babesia pages go deeper, but the most relevant botanical work includes Cryptolepis/cryptolepine and experimental artemisinin-family research. These studies are preclinical and should not be converted into human treatment claims.
Cryptolepis / cryptolepine
Peer-reviewed studies have reported activity against Babesia species in vitro and reduction of B. microti parasitemia in a mouse model. Human clinical efficacy has not been established.
See the evidenceArtemisinin / Artemisia
Some experimental Babesia models show activity; other models, including B. microti mouse work, have been negative. Species and model differences matter.
See the mixed evidenceBartonella
One peer-reviewed B. henselae study found in-vitro activity from several essential oils, including oregano and cinnamon bark, with carvacrol and cinnamaldehyde among active constituents. This does not mean ingesting essential oils is a proven or safe treatment for human Bartonella infection.
Read the Bartonella essential-oil study ↗Where evidence is missing
For ehrlichiosis, anaplasmosis, RMSF and Borrelia miyamotoi, comparable pathogen-specific herbal efficacy evidence is lacking. These infections can become serious quickly, and the evidence supporting prompt antimicrobial treatment is far stronger than evidence for herbal therapy.
