Cat's Claw Bark (Uncaria tomentosa — Primary Anti-Borrelial)
Cat's Claw is the cornerstone herb of evidence-based Lyme botanical protocols. Its pentacyclic oxindole alkaloids (POAs) — particularly isopteropodine, pteropodine, and mitraphylline — stimulate macrophage phagocytosis and lymphocyte production, enhancing immune clearance of Borrelia burgdorferi. Quinovic acid glycosides directly inhibit NF-κB — the master regulator of the inflammatory cytokine cascade responsible for Lyme arthritis, neurological inflammation, and the systemic symptoms of late-stage Lyme disease. Crucially, Cat's Claw has demonstrated direct in vitro activity against B. burgdorferi, and its proanthocyanidins disrupt the protective biofilm matrix that Borrelia forms in joint tissue — making bacteria accessible to both immune cells and antibiotic therapy. A 2005 study in the Journal of Ethnopharmacology confirmed significant anti-Borrelia activity at concentrations achievable with standard extract dosing. Use the TOA-free (tetracyclic oxindole alkaloid-free) preparation — TOAs block the immunomodulatory effects of the beneficial POA alkaloids.
⚠️ Not in pregnancy or breastfeeding. Do not combine with immunosuppressant medications. May enhance anticoagulant effects of blood thinners — monitor. Do not use with organ transplant immunosuppression. Some preparations (not TOA-free) are adulterated with inferior species — use reputable sources. May cause mild Herxheimer reactions (temporary worsening before improvement) — reduce dose if this occurs.
Japanese Knotweed Root (Reynoutria japonica — Resveratrol and BBB Penetrator)
Japanese Knotweed is the richest plant source of resveratrol — a stilbene polyphenol with exceptional properties for neurological Lyme disease. Resveratrol is one of the few plant compounds that reliably crosses the blood-brain barrier in therapeutic concentrations, making Japanese Knotweed uniquely valuable for Lyme neuroborreliosis — where Borrelia infects the central nervous system causing cognitive impairment, encephalopathy, and neuropsychiatric symptoms. Resveratrol directly inhibits Borrelia burgdorferi replication through DNA gyrase inhibition in laboratory studies. Beyond the direct anti-borrelial activity, Japanese Knotweed powerfully downregulates the cytokine storm that drives Lyme's most debilitating symptoms: it inhibits TNF-α, IL-1β, IL-6, and COX-2 simultaneously through NF-κB suppression. Emodin — an anthraquinone from the root — has demonstrated anti-spirochetal activity and provides additional anti-inflammatory effects. Herbalist Stephen Buhner, who developed the most widely used herbal Lyme protocol, considers Japanese Knotweed the most important single herb for neurological and late-stage Lyme.
⚠️ Not in pregnancy. May interact with blood thinners (resveratrol has mild antiplatelet activity). High doses may cause GI discomfort — take with food. Not in severe kidney disease. Japanese Knotweed is an invasive species — source from reputable commercial suppliers rather than foraging. The root, not the aerial parts, contains therapeutic concentrations of resveratrol.
Andrographis (Andrographis paniculata — Anti-Spirochetal and Co-Infection)
Andrographis is one of the most extensively researched anti-borrelial herbs, with andrographolide — its primary diterpene lactone — demonstrating direct activity against B. burgdorferi in multiple laboratory studies. A landmark 2020 study from Johns Hopkins (Feng et al.) screened 34 plant compounds against Borrelia persister cells and statilised cultures — andrographolide demonstrated activity superior to the front-line antibiotic doxycycline against stationary-phase Borrelia, the form most resistant to standard antibiotic treatment. Beyond Borrelia itself, andrographolide is active against Bartonella (the most common Lyme co-infection, causing neurological symptoms, joint pain, and lymph node swelling), Ehrlichia, and Anaplasma — making it essential when co-infections are suspected. Andrographolide activates macrophages and NK cells, boosts T lymphocyte production, and reduces fever and systemic inflammation through NF-κB and IL-2 modulation.
⚠️ Very bitter — GI discomfort common at high doses, especially on an empty stomach. Take with meals. Not in pregnancy (uterine stimulant at high doses). Not in active autoimmune conditions where immune stimulation may worsen disease. May lower blood pressure at high doses — monitor if on antihypertensives. Not with immunosuppressants. Some people experience temporary Herxheimer reactions — reduce dose if this occurs and increase more slowly.
Cryptolepis sanguinolenta (West African Antimicrobial — Anti-Borrelial and Anti-Babesia)
Cryptolepis sanguinolenta is a West African medicinal vine whose alkaloids — cryptolepine, quindoline, and biscryptolepine — have demonstrated among the strongest anti-Borrelia activity of any plant compound tested. The 2020 Johns Hopkins persister cell screening study (Feng et al.) identified Cryptolepis root tincture as one of just seven natural compounds with activity superior to doxycycline against stationary-phase Borrelia — the cyst forms and persister cells that are believed to underlie post-treatment Lyme syndrome. Crucially, Cryptolepis also demonstrates significant anti-Babesia activity: cryptolepine directly disrupts the intraerythrocytic life cycle of Babesia microti and B. duncani, the protozoan parasites most commonly co-transmitted with Borrelia by Ixodes ticks. This dual Borrelia/Babesia activity makes Cryptolepis particularly valuable when Babesia co-infection (causing sweats, chills, and haemolytic anaemia) is suspected alongside Lyme disease.
⚠️ Not in pregnancy (potential teratogen — alkaloid-containing herbs avoid in pregnancy). Not with immunosuppressants. May potentiate blood sugar-lowering medications (cryptolepine has hypoglycaemic activity — monitor blood glucose). Limited long-term human safety data — use under practitioner guidance. Do not use in sickle cell disease. Do not exceed recommended doses — alkaloid toxicity possible at high doses.
Teasel Root (Dipsacus fullonum / sylvestris — Tissue-Directing Lyme Herb)
Teasel root has a distinctive and specific role in Lyme herbal protocols that differentiates it from general antimicrobial herbs: it is used to direct therapeutic compounds specifically into the collagen-rich connective tissue, joint capsules, and fascial planes where Borrelia burgdorferi establishes its deepest and most antibiotic-resistant tissue reservoirs. Borrelia has evolved to target collagen because joints and connective tissue have reduced immune surveillance and antibiotic penetration. Teasel root — through mechanisms involving its iridoid glycosides (particularly loganin and sweroside) and saponins — is believed to act as a herbal 'guide' that enhances the penetration of co-administered herbs into these tissue compartments. Herbalist Matthew Wood pioneered the clinical use of teasel root for Lyme in the 1990s, and its inclusion in Lyme protocols became widespread through the report of significant symptom relief in Lyme arthritis, joint pain, and deep musculoskeletal symptoms. Some practitioners also note it helps mobilise Borrelia from tissue reservoirs — which may temporarily worsen symptoms before improvement (a Herxheimer-like response specific to teasel).
⚠️ Begin with very low drop doses — mobilising Borrelia from tissue can cause significant temporary symptom flares. Not in pregnancy. Limited clinical research — use is based on extensive practitioner experience and case reports rather than RCT evidence. Not a stand-alone treatment — used specifically to enhance penetration of other anti-borrelial herbs. Source from reputable herbal suppliers.
Sarsaparilla Root (Smilax sarsaparilla — Endotoxin Binder and Herxheimer Support)
Sarsaparilla occupies a uniquely important supportive role in Lyme herbal protocols: it binds and neutralises the endotoxins released by Borrelia spirochetes as they are killed by antibiotic or herbal treatment. The Jarisch-Herxheimer reaction — a temporary worsening of Lyme symptoms as Borrelia dies and releases lipopolysaccharide-like surface proteins, inflammatory toxins, and cell wall debris — is one of the most challenging aspects of Lyme treatment, causing fever, sweating, intense fatigue, joint flares, and neurological symptoms. Smilax root contains steroidal saponins (sarsaponin, smilagenin, sitosterol) with a molecular structure that binds spirochetal endotoxins in the gut and bloodstream, preventing their systemic absorption and reducing Herxheimer severity. Stephen Buhner specifically recommends Sarsaparilla for Herxheimer management, noting that it is most effective when taken 30 minutes before anti-borrelial herbs. It also has direct anti-inflammatory and mild immune-modulating properties.
⚠️ Generally well tolerated. May cause GI discomfort in large amounts — take with or after food. Not in pregnancy. Large amounts may increase the renal excretion of urates and chlorides — beneficial for gout but monitor in kidney disease. Do not confuse with false sarsaparilla species (Hemidesmus indicus) — different plant with different properties.
Artemisia annua (Sweet Wormwood — Anti-Babesia and Anti-Spirochetal)
Artemisia annua — the source of artemisinin, the Nobel Prize-winning anti-malarial compound — is essential in Lyme co-infection protocols when Babesia is present. Babesia microti and B. duncani are intraerythrocytic protozoan parasites transmitted by the same Ixodes ticks that carry Borrelia, with co-infection estimated in 20–40% of Lyme cases. Standard Lyme antibiotics (doxycycline, amoxicillin) have no activity against Babesia — requiring separate treatment with atovaquone-azithromycin or quinine-clindamycin. Artemisinin directly kills intraerythrocytic Babesia through the same mechanism it kills Plasmodium: it generates reactive oxygen species inside red blood cells upon reacting with intracellular iron, destroying the parasite's membrane. Beyond anti-Babesia activity, the 2020 Feng et al. Johns Hopkins study identified artemisinin as one of seven natural compounds with superior activity against Borrelia persister cells compared to doxycycline. Whole Artemisia annua plant (not isolated artemisinin) is used — the plant matrix appears to enhance bioavailability and provide complementary bioactive compounds.
⚠️ Not in pregnancy. Not in seizure disorders (artemisinin compounds have neurotoxicity at very high doses — use within recommended range). Cycle use (3 weeks on, 1 week off) to prevent tolerance and reduce potential neurotoxicity. Not a replacement for medical treatment in acute Babesia infection. Do not take with iron supplements — while iron enhances anti-parasitic activity, excess free iron can be harmful. Check current medications for CYP3A4 interactions. Source from reputable suppliers — artemisinin content in commercial herbs varies widely.
Olive Leaf Extract (Oleuropein — Anti-Borrelial Broad-Spectrum Antimicrobial)
Olive leaf extract provides oleuropein — a secoiridoid compound with documented antimicrobial activity against Borrelia burgdorferi, and synergistic activity across the full range of Lyme co-pathogens including Bartonella, Ehrlichia, Anaplasma, and Epstein-Barr virus (commonly reactivated in late-stage Lyme). Oleuropein's antimicrobial mechanism involves disrupting the bacterial membrane's ability to produce amino acids essential for replication, interfering with viral envelope formation, and inhibiting reverse transcriptase. For Lyme specifically, oleuropein has demonstrated activity against both the spirochetal form and — importantly — the cyst and biofilm forms of B. burgdorferi in laboratory studies. Olive leaf extract also supports the immune defences that are often significantly impaired in chronic Lyme: it stimulates phagocytic activity of macrophages, enhances NK cell function, and reduces the chronic systemic inflammation that causes the profound fatigue, joint pain, and cognitive impairment of late-stage and post-treatment Lyme disease.
⚠️ Well tolerated at recommended doses. May cause mild Herxheimer reaction when first starting, particularly in active infection — begin at lower dose and increase. GI discomfort possible — take with food. May lower blood pressure (oleuropein inhibits ACE enzyme) — monitor if on antihypertensives. Not in pregnancy. May enhance hypoglycaemic medications — monitor blood glucose.
Oregano Oil / Carvacrol (Biofilm Disruptor — Persister Cell Active)
Oil of oregano — standardised for carvacrol and thymol content — was identified in the landmark 2019 Johns Hopkins University study (Feng et al., Antibiotics journal) as one of just two essential oil preparations with activity against Borrelia biofilm and persister cells superior to the current combination antibiotic therapies. This is clinically significant: biofilm-protected and persister-phase Borrelia are the dominant reason Lyme disease persists despite antibiotic treatment. While antibiotics effectively kill the motile spirochetal form of Borrelia, the non-replicating persister cells and biofilm-embedded colonies are essentially antibiotic-tolerant — not resistant (no genetic change), but physiologically dormant and therefore unaffected by antibiotics that target active replication. Carvacrol disrupts these persister cells by penetrating and depolarising their membranes — a physical mechanism that works regardless of bacterial metabolic state. Thymol acts synergistically. The Johns Hopkins study used oil of oregano at a concentration equivalent to approximately 1 drop per millilitre of tissue fluid.
⚠️ Strong phenolic compound — causes significant mucosal burning if taken undiluted. ALWAYS dilute in olive oil or use capsule form. GI irritation common at high doses — enteric-coated capsules minimise this. Cycle to prevent gut microbiome disruption (carvacrol kills beneficial bacteria as well as pathogens). Not in pregnancy. May increase bleeding risk — avoid with anticoagulants. Not for extended continuous use above 4 weeks without a break.
Eleuthero / Siberian Ginseng (Adaptogen for PTLDS Fatigue and HPA Recovery)
Eleuthero (Eleutherococcus senticosus) — the original 'adaptogen' — is essential for the post-treatment and recovery phase of Lyme disease, addressing the profound, treatment-resistant fatigue, cognitive impairment, and immune dysfunction that characterise Post-Treatment Lyme Disease Syndrome (PTLDS). PTLDS involves HPA axis dysregulation (the same cortisol rhythm disruption seen in ME/CFS), mitochondrial dysfunction causing cellular energy failure, persistent low-grade neuroinflammation, and immune system exhaustion from months or years of fighting chronic infection. Eleutherosides B and E — the primary active compounds — modulate the HPA axis, reducing the blunted, dysregulated cortisol pattern of PTLDS toward a normal diurnal rhythm. They also activate NK cells and cytotoxic T lymphocytes (depleted in chronic Lyme), upregulate interferon-γ production (for ongoing Borrelia immune surveillance), and directly stimulate mitochondrial ATP production in fatigued cells. Unlike the more stimulating Panax ginsengs, Eleuthero produces gradual, sustained energy restoration without the cortisol spike that can worsen HPA dysregulation in PTLDS.
⚠️ Well tolerated. Mild stimulant — avoid in the evening. Not recommended in acute infections (may be overly stimulating to an already activated immune system). Not in pregnancy at therapeutic doses. May interact with digoxin — do not combine without medical supervision. Some sources note it may slightly elevate blood pressure — monitor in hypertension. Avoid with medications that are CYP3A4 sensitive.
