Seven Herbal Medicines Are Capable of Killing Lyme Disease Bacteria, According to New Lab Study

Research Supported by Bay Area Lyme Foundation Evaluates Anti-microbial Effects of 14 Natural Products Compared to Antibiotics Used to Treat Lyme Disease

Marin, CA, February 21, 2020—Bay Area Lyme Foundation, a leading sponsor of Lyme disease research in the U.S., today announced the publication of new data finding that seven herbal medicines are highly active in test tubes against B. burgdorferi, the bacteria that causes Lyme disease, compared to the control antibiotics, doxycycline and cefuroxime. Published in the journal Frontiers in Medicine, the laboratory study was funded by the Bay Area Lyme Foundation and supported in part by The Steven & Alexandra Cohen Foundation. The study was a collaboration between researchers at Johns Hopkins Bloomberg School of Public Health and colleagues at the California Center for Functional Medicine and FOCUS Health Group, Naturopathic.

“Since traditional antibiotic approaches fail to resolve symptoms in up to 25% of patients treated for Lyme disease and many suffer disabling effects of the disease, there is a need for novel treatment proven effective against B. burgdorferi,” said the paper’s co-author Sunjya K. Schweig, MD, CEO and co-director, California Center for Functional Medicine and Scientific Advisory Board Member, Bay Area Lyme Foundation. “Because patients are currently turning to herbal remedies to fill the treatment gaps left by antibiotics, this research is a critical step in helping clinicians, as well as patients, understand which ones may offer the most potential benefit.”

According to this laboratory study, carried out by Prof. Ying Zhang’s group at the Johns Hopkins Bloomberg School of Public Health, the seven herbal medicines that have the ability to kill B. burgdorferi in test tubes are:

  • Cryptolepis sanguinolenta
  • Juglans nigra (Black walnut)
  • Polygonum cuspidatum (Japanese knotweed)
  • Artemisia annua (Sweet wormwood)
  • Uncaria tomentosa (Cat’s claw)
  • Cistus incanus
  • Scutellaria baicalensis (Chinese skullcap)

It is important to note that each of these products have the potential to produce significant side effects in patients, and should be taken only under advisement of a clinician knowledgeable of their capabilities and toxicities.

Of these products, the Cryptolepis sanguinolenta extract caused complete eradication, while doxycycline and cefuroxime and other active herbs did not. This extract has been used for the treatment of malaria as well as the tick-borne infection Babesia, a malaria-like parasite. This study is believed to be the first time this extract has been documented to have a potential impact on B. burgdorferi, and additional laboratory and clincial studies should be conducted to investigate the potential role Cryptolepis sanguinolenta could play in the treatment of Lyme disease.

Further, Cryptolepis sanguinolenta and Polygonum cuspidatum (Japanese knotweed) showed strong activity against both growing B. burgdorferi (MIC=0.03%-0.06% and 0.25%-0.5% respectively) and non-growing stationary phase B. burgdorferi.

In contrast, Stevia rebaudiana, Andrographis paniculata, Grapefruit seed extract, colloidal silver, monolaurin, and antimicrobial peptide LL37 had little or no activity against stationary phase B. burgdorferi.

“Our hope is that findings from this study could point to new therapeutic options for doctors and their patients, and pave the way for clinical research to help patients with persistent Lyme disease,” said Linda Giampa, executive director, Bay Area Lyme Foundation.

These data may provide a basis for the clinical improvement of patients who take herbal medicines, particularly those whose chronic symptoms may be due to persistent bacteria that are not killed by conventional Lyme antibiotic treatment. However, it is critical to note that additional studies are needed to further evaluate the seven active botanical medicines identified in the study. Patients should not attempt to self-treat with these herbal medicines due to potential side effects and lack of clinical trials with these products.

About the Study
For the study, the researchers tested 14 natural products in test tubes against B. burgdorferi. Plant extracts selected for the study included herbs or agents that: have been previously used to manage the symptoms of patients who do not respond to standard Lyme antibiotic treatment; have favorable safety profiles; and can be absorbed systemically. Additional criteria for selecting compounds included anti-biofilm effects and ability to cross the blood-brain barrier. To conduct the study, the plant extracts in concentrations of 1%, 0.5% and 0.25% and antibiotic controls were each tested on growing as well as non-growing B. burgdorferi cultures. The study found that seven of these natural product extracts at 0.25%-0.5% had better activity against the stationary phase B. burgdorferi culture than the control antibiotics doxycycline and cefuroxime, both of which are commonly used to treat Lyme disease.

The paper titled “Evaluation of Natural and Botanical Medicines for Activity against Growing and Non-growing Forms of B. burgdorferi,” was written by Jie Feng, PhD, Jacob Leone, ND, Sunjya Schweig, MD, and Ying Zhang, MD, PhD.

About Lyme Disease
The most common vector-borne infectious disease in the country, Lyme disease is a potentially disabling infection caused by bacteria transmitted through the bite of an infected tick to people and pets. If caught early, most cases of Lyme disease can be effectively treated, but it is commonly misdiagnosed due to lack of awareness and unreliable diagnostic tests. There are more than 400,000 new cases of Lyme disease each year, according to statistics released in 2018 by the CDC. As a result of the difficulty in diagnosing and treating Lyme disease, at least two million Americans may be suffering from the impact of its debilitating long-term symptoms and complications, according to Bay Area Lyme Foundation estimates.

  1. look into the new GMO mosquitos. Lyme like symptoms the wolbacha bacteria. Please!!!!!!!I It is why you may have not seen mosquitos in your state. This was released in 20 states so far, mine one of them

  2. Nice. I’ve been suffering for three years and taking up to 40 supplements per day. Still sick. Going to beef up my Cat’s Claw and what about Lion’s Mane? It’s in my brain for sure!

  3. First of all, Colloidal silver at 20ppm does indeed kill all fungi, viruses and bacteria. The colloidal silver your organization tested was most likely 5ppm-10ppm, very weak topical.

    Lyme and morgellons are both caused by boron deficiencies. Mainly the culprits cannot exist in a non-deficiency body.

    One of the most powerful anti-fungal in the world is borax.The biggest medical conspiracy in the world revolves around borax.Of course, none of the ‘Lyme disease’ organizations, including John Hopkins institute, want to test this because it will reveal that 90% of all sicknesses revolve around the deficiencies of magnesium, silica and especially boron, which borax provides the supplementation needed if you do not receive this from raw plants you consume.

    %100 of people with arthritis, osteoporosis, osteoarthritis, alzheimer’s, dementia, cancer, breast cancer, tumors,lyme, morgellons, tooth decay and much much more are all Boron-deficient.
    The cure for breast cancer, which is the calcification of the soft tissues in the breast is boron/borax, since boron regulates both calcium and magnesium levels and can remove calcification in the soft tissues.

    Boron is essential in cell wall and membrane health as well as maintaining healthy testosterone and estrogen production, as well converting vitamin D to its active form, converting estrogen to its active beta-17 form, as well as increasing free testosterone in men. These sex hormones are crucial in eliminating tumors and PSA markers. Bone growth and healing as well as much more.

    5G and EMF damage directly links to Boron deficiency, As emf damages cell walls and membranes, boron is the thing to maintain cell walls and membranes.

    Did you know that a person with a broken bone can heal in a third of the time with no complications using boron/borax? Did you know a race horse with a broken pelvis can heal fully with boron/borax supplementation?

    I have more than enough ‘without a reasonable doubt’ evidence of this conspiracy against Borax/boron.

    Chem trails also fall into the Borax conspiracy because acidification of soil and toxicity with aluminum, strontium, barium, cadmium, depleted uranium, and more, which restricts boron uptake by plants. Aluminum in soil is the biggest culprit that restricts the uptake along side the use of chemical fertilizers.

    For example, a true organic apple may contain up to 20mg of boron if grown in good healthy soil. If grown in ‘hostile’ soil, that same true organic apple will have 1mg or less of boron.

    Maybe the John Hopkins Centre better test their Lyme/morgellons patients for Boron deficiency. I can guarantee 100% of the people who have Lyme and morgellons are boron-deficient, and most likely magnesium- and silica-deficient as well, as those 3 go hand in hand.

    P.S. a high calcium and vitamin C diet is the key to rapid aging and vitamin C poisoning. John Hopkins institute and others including WHO, CDC, etc has produced documents stating quite the opposite, that high calcium intake is good as well as a high vitamin C intake.

    I have piles and piles of evidence that ALL medical research institutions including John Hopkins Institute has committed numerous crimes, from perjury, murder, conspiracy to commit all of those plus concealment, false pretense, forgery, falsification of books and documents, genocide and a lot more. This will come to light in the mainstream public real soon. Thanks.

    1. Thanks. It’s great when you get an alternative view of how things seem to be. Thank you again for this input.

    2. Peter—-Interesting information. I have been checking out similar things and have found similar information. Wish we could compare notes. I am with you on much of your comments.
