Blastocystis hominis: Natural Herbal Treatments

blastocystis hominis natural treatment options byron bay herbalist australian naturopathic treatment for parasites

UPDATE: The following article outlines my successful treatment of Blastocystis and Dientamoeba fragilis using herbal medicine. Since writing this article, and thanks to mentoring from Dr Jason Hawrelak, I have come to see Blastocystis as less of an issue in most people. Please be sure to read my updated thinking on Blastocystis before assuming it is causing all of your gut issues (much like I did!). Ok, now onto herbal treatment options for Blastocystis.

Anyone who has been reading this blog will know that I have been struggling with Blastocystis homins and Dientamoeba infections since contracting them, four years ago, in the Byron Bay hinterland. More on my story here.

Today I’d like to share my herbal treatment For Blastocystis hominis and the success in finally treating both Blastocystis hominis and Dientamoeba with herbal medicines.

I have included a table of contents for you if you are looking for a specific answer. That said, I would highly recommend reading the entire article, especially if you are considering treating your Blastocystis infection.

First Off What Is Blastocystis?

Blastocystis spp. (also known as Blastocystis hominis) is a protozoan parasite that may be responsible for a range of different symptoms in people including abdominal pain, diarrhea, constipation, fatigue and skin rashes. Surprisingly there are some people that have a Blastocystis infection and show no symptoms (1).  

Again please be sure to read the updated article – Is Blastocystis a Problem After All before settling on a treatment approach for your Blastocystis infection.

We have had some difficulties categorising this unicellular organism.

At various times it has been classified as a cyst of a flagellate, vegetable, yeast, and fungus and finally landing on the protist classification (2). It also has the ability to take a whole range of different forms from vacuolar, granular, and ameboid, cyst, avacuolar, and multivacuolar (3) with the ameboid form suspected as causing the most symptoms in infected people (4).

Is Blastocystis really to blame here?

This is the million dollar question.

I have spent a lot of time researching and speaking to experts on the subject of Blastocystis trying to get to the bottom of that very question. Originally I thought that Blastocystis was an outright pathogen and should be treated in anyone that came back with a positive stool test. After years of looking into it I now think that there is one of two things going on here.

Number one. You may have contracted a particularly virulent ‘strain’ of Blastocystis and this may be the cause of all of your gut symptoms. This is definitely possible and certain strains of Blastocystis have been found and do cause symptoms.

Number two, and possibly…maybe.. more likely. Blastocystis has come back on your stool test and you have blamed this particular bug for what is really some other gut condition hiding behind it. Things like bacterial overgrowths in the small intestine (SIBO) and large intestine may be the real issue here. Other things to be on the look out would be food intolerances (coeliac disease is a big one) and possibly leaky gut.

Classic symptoms that would lead me to think your symptoms are being caused by another gut issue would be things like

  • Bloating and distention shortly after you eat a meal – Classic symptoms in SIBO
  • Blood or mucus in your stool – Possibly IBD or other inflammation driven gut issues.
  • Food intolerances, headaches and brain fog – Pointing towards leaky gut and possibly SIBO again.

From my perspective these symptoms and more point to a wider state of gut dysregulation. If you are presenting with these symptoms then Blastocystis may not be your number one priority to treat.

This second option makes Blastocystis a harder bug to treat because we aren’t 100% sure that it is causing your symptoms. A healthy approach to this particular conundrum would be to keep your mind open to other possible issues that could be causing your gut symptoms and not to focus solely on Blastocystis clearing as your main objective.

Ok. Now that little disclaimer is out of the way let’s cover how I managed to clear my Blastocystis infection.

Antibiotics for Blastocystis. Maybe not?

I have tried a number of different approaches to eradicate the bugs from my gastrointestinal tract.

The first attempt was the front line approach from conventional medicine. Metronidazole, brand name Flagyl here in Australia had very little impact on the gut infections.

I am not a huge fan of antibiotics but I figured take them, get rid of the bug and then rebuild. Since then I have come across dozens and dozens of people that have tried Metronidazole with no success. There have been case studies showing an increase in the cyst count for Blastocystis spp. after taking it. I have been speculating on how this might come about. Antibiotic resistance is a real issue with gut infections. My thoughts are that many Blastocystis strains are resistant to Metronidazole and the antibiotic cleared the gut for them to take hold.

With such dismal results I turned to herbal medicine and changed my diet considerably (article on that part coming soon).

Onto herbal treatment for Blastocystis hominis number one.

Herbal Attempt for Blastocystis Infection – Number One

For my first 90 day herbal treatment for Blastocystis I combined bereberine HCl with a herbal mixture which included a number of very obscure herbs from the Amazon.

The herbal formula was from Raintree Formulations and contained a number of very unusual Amazonian herbs

Image taken from: Raintree Formulations

After the herbal treatment I felt better and my gut symptoms improved dramatically.

At that time I was already familiar with the importance of retesting. Lo and behold my stool testing came back showing both the two protozoan bugs were still there.

Not only that but after about a month or two of feeling normal again my gut symptoms came back but this time with some non-gut related symptoms including

  • Brain fog
  • Irritability
  • Fatigue
  • Food allergies

UPDATE: circling back after years of studying gut issues I suspect that I had SIBO and large bowel bacterial overgrowth (dysbiosis) the whole time. SIBO relapse rates are high, especially when the root cause has not been addressed. If I had focused on the SIBO issue from the start I could have possibly saved considerable money, time and effort. A word to the wise…

At this point I was concerned with the state of my microbiome. I have seen a number of different cases where people continually blast their guts with antibiotics and strong antimicrobial herbs in an endless attempt to eradicate the infections.

With this in mind I turned towards a rebuilding approach. I focused on different prebiotics including lactulose, fructo-oligosaccharides and different colonic foods like green tea polyphenols. I also began consuming more probiotics including Saccharomyces cerevisiae boulardii a potent probiotic that has been shown to treat Blastocystis effectively in some people.

Thankfully Amazon.com supplies the best researched strain of this particular probiotic which you can find here.

The rebuild phase is important.

Building up my reserves and caring for my gut flora helped when I took the second round of herbal antimicrobials.

Onto herbal treatment for Blastocystis number two.

Herbal Treatment For Blastocystis Number Two

Herbal treatment for Blastocystis number 2.

At this point I was feeling pretty good. I still had issues with different foods including gluten and dairy but my digestive symptoms had improved immensely.

This time I opted for a very different herbal approach.

Instead of taking berberine HCl I opted for herbs high in berberine and other similar alkaloids. The thinking behind this approach involves the drug-resistant methods that many infectious organisms use to avoid being killed by the antimicrobials.

Berberine as an extract is one molecule (as seen below). It is true that most of the research points to it as the most efficacious and ‘active’ but there are dozens of different berberine like alkaloids in herbs such as coptis and goldenseal.

It has been suggested that these similar molecules have a synergistic effect, almost overwhelming the microbe’s ability to process them.

Berberine molecule

With that in mind I opted for herbs such as Goldenseal, Barberry and Coptis. Other herbs in the mix included Wormwood, Black Walnut and Garlic. The Naturopathic tradition has a number of overarching principles. One of these is to support the different body systems during a herbal treatment or intervention.

Thinking along these lines immunomodulating herbs such as Cat’s Claw and antioxidants such as Olive Leaf are helpful.

The herbal mix, called GI SYNERGY came in very convenient capsules and was formulated to address fungal, bacterial and parasitic infections.

Even with all this in mind my second herbal attempt failed to eradicate the two bugs.

Onto herbal treatment for Blastocystis number three!

Continued Herbal Treatment for Blastocystis infection

At this point I was getting quite frustrated.

I even spent some time considering another round of antibiotics (different ones this time). I had seen a number of people pursue the antibiotic route with no success. Some even ending up taking the triple therapy that the Centre for Digestive Diseases recommends in Sydney, Australia, still with no luck in eradicating Blastocystis.

With this in mind I stuck to the herbal antimicrobial approach. For the third time I repeated herbal attempt number two, using GI Synergy, but I extended the treatment.

I also changed a number of things including

  • Upping my garlic consumption – sometimes eating cloves of crushed garlic and at other times sticking to the garlic capsules (my favourite one here).
  • Lactulose – this prebiotic helps to acidify the gut. It boosts beneficial bacteria in the colon, increases short chain fatty acid production and reduces the ability for Blastocystis and Dientamoeba to produce their protease enzymes which protects them from our secretory IgA antibodies. For more information check out an article dedicated to this incredible prebiotic here.
  • Probiotics – I focused on taking probiotics daily including, S. boulardii, Lactobacillus rhamnosus and Bifidobacterium lactis Bi-07
  • Biofilms – While I haven’t seen any quality research on Blastocystis forming biofilms this does not mean that they don’t. For the third attempt I threw everything I had into the mix. This included nattokinase, green tea polyphenols (high in catechins) and serrapeptase in rotation.
Fresh, crushed garlic improved the treatment.

After the herbal treatment I was very keen to retest. Waiting the 4-5 weeks before retesting was difficult but as recommended by a number of different clinicians it is better to wait to let the dust settle.

Retesting after Blastocystis treatments

At this point I am well aware of the importance of retesting after treatment. I learned this very big lesson the hard way by thinking I had killed the infections and not retesting the first time. After a few months my gut symptoms came back with a vengeance. It still took another month or two to realise and get tested again!

After one round of standard antibiotics, multiple rounds of herbal treatment for Blastocystis, half a dozen tests and retests my last PCR stool test came back clean and clear for Blastocytsis and Dientamoeba fragilis.

A PCR stool test run 4 weeks after the 3rd herbal treatment for Blastocystis

Still Symptomatic after clearing Blastocystis

Here’s the problem. And I hope you’re still here reading this bit, it’s important.

Even after successfully eradicating Blastocystis and Dientamoeba my symptoms still started creeping back after 2-3 months.

Again, coming back to the high SIBO relapse issue, I think that small intestinal bacterial overgrowth was always the issue.

Please be sure to read up on SIBO to familiarise yourself with the symptoms and root causes leading to this under-recognised gut disorder.

A proper SIBO evaluation revealed methane dominant SIBO. This form of SIBO has differing symptoms and treatment approached which you can read up on in the Methane Dominant SIBO Treatment Plan article.

SIBO breath test results post Blastocystis treatment

The interpretation from the SIBO test doctor says that no SIBO is present. Many clinicians, including myself, would consider this positive due to the 10ppm rise in hydrogen (seen in the glucose test at the 30 minute mark).

There is also evidence here of colonic methane production. This is not always an issue, but in symptomatic people may need to be treated.

So, completing the proper evaluation, which I wish I had done before the endless Blastocystis treatments, I ordered a microbiome assessment of the large intestine.

The results showed considerable dysbiosis (even after all of the herbal antimicrobials, prebiotics and probitoics!) with elevated Methanobrevibacter smithii, Bilophila wadsworthia and Desulfovibrio species.

Why is this relevant.

Well the elevated Methanobrevibacter smithii in the large bowel is the same bug responsible for most methane SIBO cases. It produces methane and slows transit time, a major cause of many SIBO cases.

Both Bilophila and Desulfovibrio produce hydrogen sulfide which is slowly being recognised as a contributor in SIBO cases. Excess hydrogen sulfide production, from these bacteria, has been shown to damage the gut lining and may be implicated in inflammatory bowel disease progression. That’s pretty big news. For a deeper dive on that subject I would recommend reading – Hydrogen Sulfide Bacteria – Implications for Leaky Gut and IBD

Ubiome result showing overgrowths of hydrogen sulfide producing bacteria in the large bowel

In the image above, taken from my Ubiome report post successful Blastocystis treatment, showing overgrowths of hydrogen sulfide producing bacteria.

Unfortunately Ubiome has gone out of business.

Thryve is stepping up to fill in the gap left by Ubiome. Their gut test offers much of the same information and uses the same technology (a major plus!). For the time being they are my recommended microbiome assessment testing provider, although I wouldn’t recommend their probiotic formulations just their gut testing.

To Those Struggling With Gut Issues

If you have read this far then I’ll bet you are struggling with gut issues. Maybe you already know that you have a parasite infection and have tried antibiotics or a herbal treatment for Blastocystis. 

Many people have emailed me asking for help with their health issues. Currently I am still a student of herbal medicine (counting the days until graduation) and as such am unlicensed and can’t give any direct advice. It absolutely breaks my heart because I know how it feels.

I’ve been there. I also find it incredibly hard to recommend a specific clinician to help. Most of the ones I would recommend are booked out and are not accepting new clients. Others are still take the nuke the gut approach which can be just as destructive as broad spectrum antibiotics.

What I can do in the situation I find myself in is keep researching the complexity of gut health and keep publishing articles. In this way I can share what I’m learning and hopefully help anyone out there that needs it. I now know that a herbal treatment for Blastocystis is possible and that gives me hope for anyone out there struggling with this difficult to treat bug.

Work With Me

Treating gut infections can be complicated. As I outlined above it took me years of trying before finally clearing Blastocystis and Dientameoba. In the process I may have done more harm than good.

I know I am not the only one who has struggled for years with digestive problems. Many of you fine folks have been in touch with stories of repeat rounds of antibiotics and herbal medicine and still have all the symptoms of poor gut health.

Currently I am offering free 15 minute consultations from mid December on. These mini-consults are designed to see if we are a good fit and if I think I can help you and your digestive health issues. If you would like to be added to the wait list for your own mini-consult then please get in touch here.

  1. Hi Todd,

    My son has Blasto and I have Fragilis. I have done a similar protocol to you – did it for 5 weeks but stool sample said not erradicated. I have had Blasto before and erradicated it with the triple therapy from the CDD in Sydney you mention without any health problems. But antibiotics are still such a question for me in regards my 7 year old son. So, was wondering, on your third attempt, how long did you do the antimicrobial treatment for?? And dose? Cheers! Lara

    1. My successful protocol took 3 full months. I made sure to support my gut flora with prebiotics and probiotics during and after the herbal antimicrobials.

      It is thought that children respond well to herbal medicine and especially probiotic therapy for gut infections. That may mean a shorter protocol but you can never be 100% sure with these things.

      Let me know if I can help with anything else.

  2. Thanks Todd for that – ah, 3 months is double what we did, so that makes sense why we were unsuccessful perhaps. We also took pre and probiotics, and immune support. We took almost the same antimicrobials as you mention but in rotation. Perhaps we should stick with a selection of antimicrobials for the duration and not rotate. With the Goldenseal, Barberry and Coptis, did you simply follow the directed dose from the manufacturer? Did you use tinctures or tablets? Thx again for sharing your experience with us!! Lara

    1. not a problem at all. Happy to help where I can!

      I stuck to the one formula in capsule form. I am still waiting to hear back from a very experienced clinician who deals with these infections daily on the tincture vs. capsule debate. I know for sure that tinctures (coptis, pomegranate, propolis etc) work very well on other protozoan infections (giardia, cryptosporidium) and bacterial infections (H. pylori, klebsiella) but Blastocystis seems to be an unusual little bug. Some strains appear to be very resistant.

      I did find that lactulose was incredibly helpful with my symptoms http://www.byronherbalist.com.au/lactulose-prebiotic/
      again that may be strain dependant – some Blastocystis strains are impaired by the low colonic pH that prebiotics create while other strains just power on.

  3. And did you follow the manufacturer directions for dose? Thanks for the lactolose tip (we were taking galactooligosaccarides and beta glucans). And looking forward to reading your article regarding tinctures or tablets when done!

    1. Sorry on the delay! Dosage was per manufacturer. All of the herbal medicines have a therapeutic range and I wouldn’t want to take more than the recommended dose for such a long time (short term treatments you can up the dose)

  4. Hi Todd! I have been battling BH since I learned I had it along with C. Diff. The latter has since cleared however, BH has not. I have gone through 2 months of Biocidin/Antimicrobial tx, changed my diet, getting rid of all the sugar bug eating foods however, I still have symptoms. I plan to start round 2 soon, I understand cycling treatment with the moon will better my chances to rid the parasite. What are your thoughts? I understand you can’t give prescriptions, but can you provide suggestions as I remove into round 2. Much appreciation!

    1. Can you suggest anything else as I am severely lactose intolerant and would be unable to take Lactulose. Also I can’t take probiotics and even most probiotics . But I can tolerate Sboulardii.

      1. hmmm…s. boulardii is a key probiotic here so that is helpful. The biocodex strain is the best studied one (florastor in the states). Apart from that we might have to dig a bit deeper around your history and symptoms.

  5. Hey Todd,
    My wife has been suffering with blasto for over a year now (long story – seems very similar to yours!), with multiple therapies having limited effect. I was wondering about the doses of your “final” treatment regiment….it would be very helpful to know what they were and also the brand of products you used. Others might also find this helpful…

    Thanks!
    Kevin

  6. Hey bud,

    I’m in the process myself seeing a bioresonance therapist to treat BH coming up to 5 years now. The root cause and low success of herbs so far likely to have been high stomach ph which was caused by helibavtor pylori. I’m waiting for my PCR results this week so will share my story if successful with my track, but sounds like I’ve got a next phase of artillery with your final protocol if needed. Great to see your success. As per Kevin, would be great to get some brands etc of lactulose etc.

    1. Hey Kevin, thanks for your comment and sorry to hear you’ve been struggling with blastocystis too. It seems like a very common story.

      I decided not to post the brand or doses intentionally. After years of self-experimenting with high dose antimicrobial herbs I’ve come to the opinion that the treatment of this particular bug should be done under the care of a gut savvy clinician.

      I get that my answer can be frustrating but from my own experience I may have done more harm than good with the antimicrobial treatments. A more balanced approach with prebiotics and targeted herbs may be more indicated if blastocystis is the issue.

      This is the main driving force for me going back to university and studying to be a herbalist so I can help to provide people with the care they need with these complicated gut issues.

      Todd

      1. Hi Nick, definitely keep us posted on how you go. Herbs should be tailored to the individual so brands and doses were avoided (as per comment above too).

        Any lactulose brand should do. I have used lac-dol with good success. There may be a SIBO picture with many blastocystis cases so go low and slow with this particular prebiotic!

        1. Hi Todd,

          I am the wife of Kevin, and I am the one who has been suffering from blastocyst h. subtype 3 for almost 2 years. Kevin and our children also have stomach pain from this pathogen, but nothing as severe as me. I am having trouble finding a ‘gut-savvy clinician’. How would one go about that? I have stopped vomiting by using herbal treatments but can not completely clear the infection. We recently visited the Tropical Public Health institute in Basel, Switzerland for help and the parasitologists there were not aware that blastocyst hominis can cause monthly vomiting and such severe symptoms. All the famous parasitologists I have met do not seem to have a clue about a cycle connected with the moon, yet this seems common knowledge for many herbalists and my symptoms match a monthly cycle. Some of my success was in using the carnivore diet, since carnivores (large cats etc.) do not carry blasto. in the wild. Do you know of any ‘gut-savvy clinicians’ in Europe ?

          Thanks, Danica
          ps.
          We are currently near Geneva working on Ebola-crisis related research work…but we are in our own crisis with blastocyst hominis. (an unrecognized pathogen??)

          1. Hi Danica,

            Sorry to hear you are still struggling with gut health issues! I, much like the parasitologists you have seen, have never heard of Blastocystis causing such intense symptoms. I suspect there is an underlying gut condition at play here.

            Has your family been tested for Helicobacter pylori? This particular bacterial infection/overgrowth would be number one on my radar with symptoms such as yours. It can also be transmitted horizontally (between family members etc) so that may explain the shared symptoms (more here – https://www.byronherbalist.com.au/parasite-infections/helicobacter-pylori-notoriously-popular-bacteria/).

            Please keep us posted on how you go (and whether H. pylori has been ruled out already)

            Todd

  7. Omg, thank you for this insight Todd. I have been suffering from gut health problems to the point of depressed life and loss of partners who couldn’t handle my depleted energy state and optimism, because of the fatigued adrenals. This gives mi much home because still have blasto.

    My naturopath suggested I should eat, cinnamon, cloves, black pepper garlic and nutmeg with every meal if possible. I just ordered tests today will see if it worked, if not I’ll try your approach.

    1. Hey Jure. The spices and herbs sound like a good approach, especially the cloves and garlic. Just remember to keep an eye out for other possible gut conditions that may be the issue. I have found people tend to blame blastocystis just because it is easy to find. Keep us posted on your progress!

    1. Hi David.
      I tried a handful of diets from ketogenic to low-fat (that one is more indicated for Giardia infection though). I’ve come to the thinking that it is very individual and depends on what else is going on in the gut. Avoiding alcohol is definitely a good idea and I found a lower refined carbohydrate diet to be helpful too.
      Hope that helps!
      Todd

  8. Thanks Todd. I appreciate the advice. I’ll let you know how I go. One last question – do you think apple cider vinegar would perform a similar function to a lactulose prebiotic?

    1. No problem at all. Apple cider vinegar may help with certain digestive symptoms but it won’t work like lactulose. Lactulose has a very specific effect on the gut flora. I found it incredibly helpful when I was treating my blastocystis infection.
      Keep us posted on how you go!

  9. Hello Byron,
    I really appreciate your website. I have been struggling with natural treatments for blasto these last few months (mostly essential oils like oregano, cloves, cinnamon and thyme and anti-parasitic tinctures with wormowood, etc. and s. boulardii + l-glutamine) and although they make me feel a bit better, the parasite is still there and I still feel sick. I was also diagnosed with SIBO / dysbiosis via a breath test but have no further details regarding this as the drs here in France are very limited what concerns this diagnostic. I am now wondering if I should concentrate myself on treating SIBO and if then the blasto will disappear or stop creating other symptoms?

    I must say that I starting feeling bad about 8 months ago after an antibiotic treatment for an UTI and right after I did (my first) gastroenteritis… Your opinion is very valuable to me, thank you in advance!

      1. Hey Roxana,

        Thanks for taking the time to share your experiences.

        Gut conditions can be complex but I would place SIBO treatment well above treating a blastocystis infection. The good thing is that most SIBO treatments will help on the blastocystis front too! It seems like you are on the right track with the herbs (although we focus on whole plant herbs rather than essential oils as they can be very rough on the beneficial gut bugs!). Was your SIBO breath test methane dominant, hydrogen or both? All very important in the treatment and maintenance phase.

        Hope that helps!

        Todd

  10. Thank you for replying, Todd!
    Unfortunately I don’t know whether I have dominant methane or hydrogen SIBO as the dr wouldn’t give me any details / no written diagnostic either. And this was the only dr in the area which does the breath test… He gave me some dietary tips and some natural treatment which doesn’t work. Are there herbs / natural SIBO treatments which work for both types?

    Wishing you all the best!

    1. No problem, happy to help! There are a few herbs that overlap but the approach is very different when treating methane vs hydrogen dominant SIBO. It is possible to take a guess at which one depending on your symptoms. Here is some info on methane dominant symptoms and general treatment approaches https://www.byronherbalist.com.au/bacterial-infection/sibo-methane-dominant-treatment-plan/
      Hope that helps! Sorry I can’t give specific health advice.
      Todd

  11. Wow! So glad I came across your site after receiving the news today I have BH. I’ve had all the classic symptoms for YEARS and told everything from ‘it comes with age’, you’ll have to live with bloating, etc, ‘it’s in my head’… After reading your own journey I’m not going to waste time on Flagyl and go herbal. Will keep reading and share information with my nutritionist / herbalist. Thank you!

  12. Thanks for the kind words dawn! The website has been a labour of love, lots of personal experience and countless hours of research and input from some very gut savvy naturopaths who have been mentoring me! I hope it helps 🙂

    Just a comment on blastocystis. I have started to see it as a proxy for some deeper gut imbalances (not saying it’s not an issue but just to keep your eyes out for other gut issues…SIBO, large bowel dysbiosis etc).

    Keep us posted on your progress and sing out if I can help!

    Todd

  13. Hi Todd

    I have a 5 year old with BH. He is on alkaline diet and has no carbs, sugar, animal products. His tummy is really big which is a concern. His stools are normal and he goes at least twice a day. He seems to be always hungry and craving carbs. His homeopathic dr prescribed berberine but that didn’t work. Can you help???

    Thanks
    Leigh

    1. Hey Leigh,

      The best I can do is put you on my wait list for mid December (currently I am just finishing my degree and am not yet licensed to treat or give specific health recommendations) – see here for more – https://www.byronherbalist.com.au/appointments/

      There may be some concurrent gut dysregulation going on here. Constant bloating may be a sign of SIBO or possibly even methane dominance in the large bowel (you would have to test here to confirm).

      Sorry I can’t be of more help!

      Todd

  14. Hi Todd,
    I really appreciate your article. I`m an Australian living in Switzerland and don`t have much faith in doctors. Four weeks ago I started experiencing quite violent diarrhoea. I waited a couple of weeks before going to the doctor thinking it was something that would clear up on its own. A blood test turned out clear (I’m a relatively healthy person). However, the stool test showed that I have blastocystis hominis. I kept/froze a portion of the fish that I think caused it – I haven`t been anywhere exotic so it must be something I`ve eaten – this makes me really angry because it`s like I paid to get sick! Funnily enough, it cleared up for a few days but then the diarrhoea returned. I just started taking Flagyl (antibiotics) but like you, I have little faith in antibiotics and prefer natural solutions because I want it eradicated not just slowed down. I will try the products you recommended. Once again, thankyou for the time and effort you put into your article. I will let you know how things turn out. Janine

  15. Hi, I am desperate for help, I have major gut issues, nausea, diarrhea almost every night and through the night, I have a skin rash all over my
    body, and it’s getting worse. I haven’t been to the doctor yet, I am continuously researching online and came across your article. My gut is in constant pain am bloated, I really want to get my gut right naturally and am trying to avoid antibiotics.

    1. Hi Carleena.

      The bloating, nausea, gut pain and rashes may be pointing to a SIBO picture. As it sounds quite serious it might be best to see a doctor (hopefully they will rule out serious infections and things like helicobacter pylori – more here https://www.byronherbalist.com.au/parasite-infections/helicobacter-pylori-notoriously-popular-bacteria/)

      Have a read of the Complete Guide to SIBO to see if you relate to some of the signs and symptoms – https://www.byronherbalist.com.au/gut-health/sibo-complete-guide/

  16. Hi Todd,

    Thank you for your work and providing guidance in this complicated matter!

    I have a few questions:
    1. Does wormwood mean „sweet wormwood“?
    2.a) Did you take all of the above mentioned herbs (Goldenseal, Barberry, Coptis, Wormwood, Black Walnut, Garlic) simultaneously during your 3-months treatment period? Or perhaps only 2-3 at a time and then changed to the next 2-3?
    2.b) If only 2-3 at a time, how long approximately did you take any combination of herbs in a row – i.e. 2 weeks herbs A + B, the next 2 weeks herbs C + D, thereafter 2 weeks of herbs E + F, and then repeated this pattern?
    3. Are there herbs that go particularly well with or compliment eachother (i.e. barberry + goldenseal or rather barberry + garlic etc.)?
    4. Did you include Cat’s Claw and Olive Leaf from the beginning or only towards the end of the protocol?

    Can’t wait to begin treatment as this blasto diagnosis seems to be the last piece of the puzzle…

  17. Hi Todd,

    I have the exact 2 parasites that you had and so grateful for your blog. Would you mind giving the posology details of your round 3 please?

    Specifically for the S. boulardii (how many mg & how many times a day etc.), the biofilm busters and garlic? And for how long?

    Thank you so much! Really hoping to get rid of these.

    1. Hi Tina, thanks for taking the time to leave a comment!

      1. Wormwood (in this case) refers to Artemisia absinthium (more of the common wormwood).

      2. Each herbal round took about 3 months – Blastocystis is very difficult to treat and generally takes a longer approach (I’ll update the article this week…looking back on it it isn’t clear enough)

      3. For each of the attempts outlined above I took all of the herbs together.

      4. Cats claw and olive leaf from the very start…

      Circle back in a week or so…I will do a major overhaul of the article as it needs updating 🙂

      1. Thank you Todd! So I will wait before ordering my herbs until I read your update next week.
        I appreciate your time and efforts!!

          1. Hey Tina,

            Thanks for your patience!

            I have updated the article (included links to the products that I used) and included a link to an article I would love everyone with Blastocystis to read before going down the never ending treatment route.

            Hope it helps! Feel free to post up any questions or comments. I love the feedback.

            Todd

    2. Hi Seb. Unfortunately it was so long ago that I can’t remember dosages. The timeline is long – 3 months per round.
      Blastocystis and d. frag can be very very difficult to treat and in most it might not be necessary to completely eradicate them. I think I have done more harm to my gut than good going so hard for so long!
      More on that in an update I am writing now…

  18. Hello Todd, I have contracted blastocystis hominis too.
    The doctor has me on omega-3 and vitamin D supplement.
    I’m eating garlic, cloves and taking probiotics SB.
    Are trying to remove all carbs from my diet.
    What else can I do to remove it?
