Parasite treatment considerations: Blastocystis hominis and Dientamoeba fragilis

Parasite treatment considerations: Blastocystis hominis and Dientamoeba fragilis


Intestinal parasites are often overlooked as a potential cause of disease in the digestive system and in many other seemingly unrelated health concerns. There is increasing evidence of the ability to cause illness by relatively common parasitic organisms previously considered to be commensal organisms (i.e. living together in balance with other organisms in a given environment). Thus parasite treatment options become important ‘getting healthy’ health strategies to consider.

In such cases it is important to investigate and remove the parasites, where they are found in people presenting with significant gastrointestinal complaints (cramping, bloating, diarrhoea, constipation, pain etc) combined with fatigue, low energy, brain fog and memory lapses, anxiety, depression or headaches, to name a few.

Dientamoeba fragilis (D.fragilis) and Blastocystis hominis (Blastocystis) are two common microscopic parasites found throughout the world that can negatively impact many aspects of health in both children and adults. These two parasites are quite common in Australia in both children and adults.

In this post I’d like to share my experience in providing natural parasite treatments in the Sydney clinic as well as online (via Skype/ Zoom), plus provide you with an overview of the current research in this area, and discuss natural treatment options.

Causes of parasitic infections

Blastocystis and D.fragilis are both a protozoal-type microbes that can infect the human digestive tract. Causes of parasite infections are many but most include altered internal environment (e.g. excess of internal and/ or external toxins, poor digestion and elimination, and impaired detox system), low immune system, depleted adrenals causing low energy and tiredness, too much stress, damaged gut wall, poor diet and microbiome imbalances.

The microbiome comprises all of the genetic material of all the microbes within the human gut.

Often parasites are acquired during overseas travel when eating poorly prepared food and drinking unboiled local water. Many are infected by having either direct or indirect contact with people who are carriers e.g. people who have parasites and work in restaurants and take-away food outlets. Importantly, many of those infected are asymptomatic carriers and don’t know they are infected (1).

The parasites spread through the faecal-oral route particularly under poor hygiene conditions, contaminated foods and drinking unboiled dirty water. Once a person has been infected, the parasites live in the large intestine and are passed in faeces. The parasites are protected by an outer shell, therefore they can survive outside the body and in the environment for long periods – months and even years (2).

Symptoms of parasitic infections

Symptoms severity depends on the parasite genotype (there are multiple species of Blastocystis, up to 15 have been identified so far, some of them may not be harmful though), person’s own genetic makeup, levels of immunity and age, to name a few. Stool culture (minimum of three days stool samples or a one day PCR stool test) currently provides the most sensitive diagnostic method for evaluating the presence and levels of Blastocystis and D.fragilis.

However, the tests are not 100% reliable and some tests can produce false negative results due to the varying methodologies, the PCR test (that looks for DNA of different microbes) is being considered as the most reliable at present. It’s not uncommon for both parasites to be present in the large intestine at the same time producing more severe symptoms and increasing the complexity of treatments (3).

The bad news is there is not one typical symptom associated with these parasitic infections to help with identification and diagnosis. The two parasites are associated with a range of similar non-specific gastrointestinal symptoms including diarrhoea and/ or constipation, abdominal discomfort and cramping, reflux (heartburn), severe bloating, flatulence and cramping pain.

Other symptoms may include nausea, vomiting, headaches, dizziness, weight-loss, chronic fatigue, depression, low-grade fever, bloody stools and anal itching. Some case reports have also suggested that inflammatory bowel disease (IBD) such as colitis and Crohn’s disease, and irritable bowel syndrome (IBS) are associated with Blastocystis and/ or D. Fragilis infection. Interestingly, IBS is the only functional bowel disorder where a protozoal infection has been found in almost half of diagnosed cases (2).

Intestinal permeability or leaky gut also increases in patients with Blastocystis and D.fragilis and other parasites such as Giardia, because they actually damage the gut wall with the toxins they produce. The parasites also adhere to the gut walls creating structures called biofilms ‘aka’ bunkers where they live and hide from the immune system.

This finding supports the view that leaky gut increases during the course of pathogenic protozoan infections, causing damage to the intestinal wall, while other non-pathogenic protozoan infections have no effect on it. The increase in leaky gut in patients with Blastocystis supports the view that it can be considered a pathogenic protozoan (3).

Having stated the above symptoms and negative aspects of parasitic infections, it’s important to note that it is not yet definitely proven that Blastocystis is a pathogenic parasite in all cases. A more accurate term proposed recently by the Blastocystis expert Professor Rune Stensvold, is that Blastocystis is a ‘symbiont’, so in many people it could well be just be an incidental organism (an organism that normally lives on a host other than its normal host).

Some researchers are even proposing it could be commensal and be playing a beneficial role in some way. More research will bring answers in time but in the meantime, each person needs to be evaluated based on the facts (test results) and their symptoms.

Testing for parasites

At present the most reliable and acurate test for intestinal parasites is a stool test called Faecal MCS and PCR test (MSC stands for Microscopy, Culture and Sensitivity; PCR stands for Polymerase Chain Reaction which tests for DNA fragments of parasites). Your GP can refer you for this test which is covered by Medicare in Australia. The test detects 10 most common parasites and bacteria:

  • Parasites:  Dientamoeba sp, Blastocystis sp, Cryptosporidium sp, Giardia sp, Entamoeba histolytica
  • Bacteria: Salmonella sp, Campylobacter sp, Shigella sp, Yersinia enterocolitica, Aeromonas sp,

Other tests I commonly refer my clients for are performed by functional labs I work with and include:

  • GI Effects by Genova Diagnostics lab – this is currently the most reliable and comprehensive test that also covers detailed gut microbiome analysis, digestive function and gut inflammation markers. It provides invaluable information for tailoring treatment protocols for each client, the management of gut health and overall health as well. The test is done at home (one stool sample is needed) and then posted for analysis to the US.
  • Complete Digestive Stool Assessment (CDSA) where a stool sample is collected every day for 3 days to gauge the digestive function and microbiome bacterial balance. This test is done at home and the specimen are couriered to the lab for analysis. DNA Multiplex PCR test can be added to any CDSA test if parasites are suspected.

Treatment overview

Overall, there are two groups of people with confirmed parasitic infections (via the most reliable PCR test):

  • Individuals with no apparent symptoms, gut or other symptoms as described above, who are otherwise healthy and well (as reported by them and supported by ‘normal’ blood test results).
  • Others who suffer from moderate to severe symptoms that significantly interfere with their health and wellbeing, often leading to long-term poor physical and emotional outcomes and decreased quality of life. These are the people who need to consider embarking on parasite treatment such as one described below.

Many people may suffer for years or decades with severe IBS-like symptoms that can’t be explained before a proper diagnosis is made. In fact, they are often misdiagnosed as having ‘IBS’, sadly without a hope of improving if the parasites are present but not investigated and removed or decreased in numbers.

Doctors most often treat parasitic infections with a combination of strong antibiotics, after which some patients (but not all) report either resolution or a significant reduction in symptoms.

However, such parasite treatment methods often fail further down the track, even after repeat treatments with strong antibiotics, as the parasites become resistant to the drugs and the gut and immune systems get damaged, and subsequently not able to protect against re-infection. Many patients may even get worse because of the gut damage done by the antibiotics and the weakened immune system.

My current understanding is that there is no one reliable parasite treatment /therapy to eradicate Blastocystis and/ or D.fragilis. However, there are naturopathic parasite treatments, including remedies utilising specific antimicrobial and antiparasitic herbs, that are helpful in killing off parasites over a longer period of time (3-6+ months).

It’s a much gentler, albeit longer, method than repeated courses of antibiotics which, as mentioned above, often don’t work, as parasite become resistant to them. In addition, gut damage and microbial imbalances from taking antibiotics can be challenging to repair long-term. Importantly, Blastocystis can also stop responding to antiparasitic herbs as it can adapt if the same herb(s) are prescribed for a longer period of time.

Fortunately, by using multiple herbs with many different natural constituents makes it much harder for the parasites to become resistant to treatment, as they act synergically. Also, the herbs and supplements support gut lining, the liver, digestion and absorption of nutrients, thus supporting and speeding up the healing process at the same time.

One effective natural parasite treatment strategy is to employ a periodic rotation of specific antimicrobial herbs throughout the treatment. This method will give the immune system an advantage over the parasite’s abilities to adapt, thus increasing the likelihood of eradication over time.

Homeopathic remedies are also helpful when used in conjunction with herbs and dietary therapy to further progress the removal. Other synergistic nutritional supplements and foods are also key in making the parasites wanting to permanently move out. These include: garlic, ginger, black pepper (5), herbs like wormwood, black walnut, turmeric, Pau D’Arco; pomegranate husk, citrus seed extract; oregano oil; prebiotics and probiotics, especially Saccharomyces boulardi.

Unfortunately, many people find that after trying to eradicate Blastocystis for months or years, they still test positive for it. As mentioned above, the parasite becomes resistant to drugs or natural treatments and therefore they may never be fully eliminated in some people, even after years of treatment.

On a brighter note, even though the parasites are still detected on testing, many people feel much better and their symptoms subside considerably, whilst they adhere to specific nutrition, supplements and lifestyle choices which support the immune system and the gut.

It’s known that taking multiple rounds of antibiotics has many negative effects on the gut and the immune system function. Therefore it is prudent to investigate other possibilities for the symptoms first. For example, many people (working with gut health knowledgeable practitioners) who just focus on healing the gut and improving microbiome health by using prebiotics, probiotics, dietary adjustments, etc, will significantly improve or even solve their symptoms all together.

As mentioned above, before commencing any parasite treatment, it’s very useful to perform a comprehensive digestive stool analysis (CDSA) that uses PCR technology (which looks for DNA of different microbes). This test also measures the levels of dysbiosis (imbalances of gut flora), pancreatic function, nutrient malabsorption, and other digestive markers.

IMPORTANT CONSIDERATIONS: After performing the tests, many people find that having Blastocystis is not their main problem or the cause of their symptoms. Instead their source of ill health could be SIBO (small intestine bacterial overgrowth), giardia (another common parasite), dysbiosis, candida, hernia, or just high stress.

By treating those other identified imbalances first, many people start to feel much better and their symptoms decrease significantly, thereby avoiding having antibiotics that may be unnecessary. They may still have Blastocystis, according to the tests, but they feel well and have no symptoms.

Natural parasite treatment considerations

From my experience as well as via feedback from other natural health practitioners working in this area, treatments, both natural and conventional, are often long and complex, and cover a number of aspects as determined by patient’s severity and duration of symptoms, his/ her current state of health, stress levels and their nutritional status.

It’s essential to stage and plan the parasite treatment over time and not panic and attack the parasites straight away with ‘heavy weapons’ such as multiple antibiotics, strong antimicrobial herbs and other harsh purges. These aggressive strategies will not work in most cases as the parasites defend themselves cleverly whilst the gut and immune system are depleted by the treatment.

To make major inroads, you’ll require patience, perseverance and education on how the body works to naturally expel the parasites, combined with the help provided by specific remedies and herbs. Understandably, most clients want the parasites out as soon as possible regardless of their immune system strength and their bodies’ readiness for the likely long and often tricky fight.

More often than not there is also a significant stress component to deal with as clients find that having been diagnosed with parasites is unnerving, uncomfortable and physically and mentally draining.

My parasite treatment protocol is personalised for each person and it typically includes the following stages:

  • Preparatory phase (duration: 4-8 weeks) – boosting the immune system, the adrenal glands, decreasing stress, gut and liver support plus improving body’s detox capacities as well as removing some toxins prior to the parasite eradication step.
  • Parasite purge (duration: 3-4 months or more as per client’s needs) – antiparasitic treatment using specific herbs, supplements and foods.
  • Removal of toxins and debris / gut repair/ digestive support / improving sIga secretion (ongoing: before, during and after the protocol). Main medicines utilised are: herbs, supplements, specific foods, lifestyle modifications.
  • Liver and detox support (duration: ongoing – before, during and after the protocol). Main remedies utilised are: herbs, supplements and specific foods.
  • Stress release/ reduction activities (duration: ongoing – before, during and after the protocol) – tailored stress release techniques to support the immune system, adrenals and the whole body and mind to cope with the long-term treatment.
  • Parasite treatment considerations - key nutrition guidelinesAnti-parasitic diet and nutrition (duration: ongoing – before, during and after the protocol) – this is the key part of treatment and the foundation of good gut health involving leaky gut repairs, beneficial bacteria levels and building immune system resilience to minimise possible re-infestation in the future. Adherence to the dietary guidelines is vital and plays an important part of the treatment; however, nutrition alone is not likely to eradicate the parasites.
  • Over time I developed specific nutrition guidelines for all clients undergoing natural parasite treatments, using certain foods, herbs and herbal teas as effective anti-parasitic medicines, in addition to the key antimicrobial and anti-parasitic herbs and supplements. Included is a summary of my recommendations, you can download it and start implementing the guidelines today. Download the Key Nutrition Guidelines for Parasitic Infections here. 

This natural parasite cleanse works quite well for people who have had the parasitic infection for shorter periods of time (for months and up to 12 months).

For clients with long-standing infections (sometimes lasting for 5-10+ years), a combination of antibiotics and natural medicines may be necessary, providing they go through the preparatory and gut repair treatment phases prior to taking antibiotics, and are well/ strong enough to tolerate high doses of antibiotics.

These individuals also need to follow the remaining steps of my natural parasite cleanse after taking antibiotics, as stated above, to restore gut integrity and the immune system function. Naturally, each client needs to be assessed on an individual basis and treatment tailored to their needs.

If you live in Australia consider contacting me for assistance with parasite infection treatments for Blastocystis, D.fragilis or other parasites. Over the time working in this area I developed my own treatment protocols based on the clinical experience, exchange of ideas with and feedback from other practitioners and extensive, ongoing research I conduct on this topic to keep up to date.

To better serve my clients I developed the Natural Parasite Cleanse Program to provide personalised, comprehensive and methodical treatments to eradicate parasites and improve the gut health and function in general. Find out more about this unique program here.

For convenience and easier access to natural parasite treatments, I offer Skype consultations Australia-wide and also see clients in the Sydney CBD clinic. I’m afraid I’m not able to offer any specific treatments or advice to individuals based elsewhere.


Parasitic infections of the intestines are emerging as significant components of many digestive and other inflammatory conditions, and need to be taken into account during initial assessment, when indicated. Particularly, if you suffer from multiple, non-specific gut symptoms such as IBS and other non-specific symptoms such as anxiety, unexplained sleep disturbances; mood disorders or brain fog; aches and pains etx, and have not been investigated for the presence of parasites.

Please consider this option as part of your health assessment. It may well be the missing piece in the puzzle!

In conclusion, a long-term success with eradicating or significantly decreasing parasite levels depends on your overall gut health, well-functioning immune system and effective stress management, including good sleep and rest.

Unless you change your internal environment (terrain), re-activate your immune system to detect and kill the clever, ever changing and hiding pathogens, and make the internal environment more hostile (i.e. more healthy) for opportunistic parasites, viruses and bacteria, there is little chance to permanently improve or succeed long-term.

    Hi Joanna,
    Thank you for writing this article. I have tested positive for Dientamoeba fragilis on a couple of ocassions. The first time I was treated with antibiotics which appeared to work. The second time I was treated but a follow up stool test came back positive again. My doctor now is reluctant to treat the parasite again with antibiotics saying some people just live with it and it should be okay. I can not find any research to support her view. I have ocassional symptoms similar to IBS such as alternative bowl movements, abdominal pain, bloating and gas, headaches, rash (all which I think may be caused by the parasite) however when I mentioned this to the doctor she seemed to think I just have IBS (even though I have tested positive for Dientamoeba fragilis). I am very confused now if it is a normal parasite that just lives in you or if I really should be treated for it. Any of your expertise on this parasite would be appreciative.
    Thank you in advance.

      Hi Tim
      Thank you for your comment. Yes, some doctors are of a view that parasites are a normal occurrence and no treatment is necessary. Sometimes this may apply but from my clinical perspective we need to consider two main aspects: which parasite is it and if it causes symptoms indicating that the body and the immune system can’t keep it down, which seems to be the case here.

      Being a natural medicine practitioner, I always look for the cause of any symptoms/ conditions first. Needless to say this is the key to address parasites, or anything else effectively = remove the cause and the parasite usually disappear as well as the inner environment becomes hostile to them. With parasites the causes are many but most include having excess of internal and/ or external toxins (very important to assess), poor digestion and elimination which create toxins in the body), impaired detox system, low immune system, depleted adrenals, too much stress, damaged gut wall, microbiome imbalances, and poor diet.

      Also, from my clinical experience most people need to do the preparation stage to strengthen the body’s immune system (as it fights the pathogens), the gut and adrenals. Then tackle it with either herbs or antibiotics (in some cases). Using the big guns i.e. strong antibiotics straight away rarely works and often the parasite may even become more resilient and able to ‘hide” from them.
      Therefore I suggest you consider my treatment suggestions, as per the article, tailored to your needs of course, and spent some time dealing with many aspects in play. This is not the time to do it on your own as there are many dimensions to the treatment that need to be address. Therefore I suggest you find a skilled natural medicine/functional medicine practitioner who could guide you through it.

      All the best

    I am interested in your views on treating both D.Fragilis and B.Hominis with Diatomaceous Earth and Papaya seeds. I have done much research into natural remedies since my 11 year old daughter has recently had a PCR test come back showing both these parasites detected.

    • Joanna Sochan August 31, 2016 at 3:43 pm - Reply

      Hi Monica
      I don’t use the clay or papaya seeds in my parasite treatments therefore I can’t comment on their efficacy. From my experience having both parasites requires antimicrobial herbs and nutrients for a period of time (commonly repeated for 2-3 cycles) but not before the immune system and the gut are both supported prior to the parasite removal therapy.

    Hi Joanna,
    Earlier this year I was diagnosed with having Dientamoeba Fragilis and the Blastocystis Hominis. I was treated with 4 antibiotics over 10 days, followed by 4 weeks of probiotics. This managed to remove the blastocystis but I am still problematic with the D.Fragilis. I had 3 of my family tested and they all have the same bug. (Still waiting to test my other daughter who has no symptoms). The centre now recommends I have the colonoscopy and have the antibiotics inserted. They won’t treat children. I am looking for a potentially natural solution for the whole family so that reinfection is avoided. Is this something you can help me with? And what is your success rate like?

    • Joanna Sochan September 11, 2016 at 7:23 pm - Reply

      Hi Kathleen
      Sorry to hear you are looking at the option of antibiotic internally to try to eradicate D.fragilis. Do you mean the other family members have D.fragilis or both bugs? There are a few natural treatments to consider (long-term – could be 6 months ++) depending on the circumstances and the success rate is hard to predict – more like 50/50. Where are you based?

        Hi Kathleen

        Yes, these are strong antibiotics for any age. Children respond well to natural medicines used to treat parasites. I suggest you consider doing a natural treatment first and if it doesn’t work re-consider the antibiotics combined with natural medicines to protect and repair the gut and support the immune system.

    Hi there!

    I’ve been trying to eradicate blasto for the past 4 months. What I’ve experienced is exactly as you say, I’ll be doing/feeling great and then I have something I shouldn’t and it’s ten fold. My question is I have been taking l glutamine and GI synergy. All which help as well as eating four cloves of garlic daily. Yes I stink! I read there are some Chinese herbs as well that are helpful. When you say rotate herbs is this what you are referring to? I’m working with a natural path now, but I’m starting to wonder if she is educated enough on how to eradicate this from my body. It’s something that definitely has to be done to regain my health. I’ve basically developed a awful autoimmune disease from it. Thank you:)

    • Joanna Sochan October 11, 2016 at 6:13 pm - Reply

      By antimicrobial rotation I mean using different herbs very 2 weeks or so (alternating them) as the parasites are able to adapt to them quickly and become resistant. I usually alternate 2-3 different herb/ nutrient combinations for a period of time. Eradicating parasites takes time and often the treatment needs to be repeated 2-3 times. Sometimes that’s not enough and some people choose to take antibiotics and then repair the gut with natural medicines. Unfortunately there is no 100% effective way to do it at present, as far as I know.

    Hi Joanna I have the same issue tested positive for blastocystis and dientomeobia twice , my doctor said they don’t normally treat unless symptomatic which I was comming up in huge all over body welts , raised esinophills as well as high histamine and low cortisol levels . I was on a course of 1500 mg of flagyl a day for two weeks which made me feel awful and didn’t work instead i acquired another new bacterial growth of Aremonas. She doesn’t want to give me any more antibiotics , just referred me to an immunologist that I won’t be able to get to see till mid next year .
    In the meanwhile I am taking daily antihistamines and taking daily pre and probiotic powders …
    I am wanting to try something that is prooven effective to work , have read up about a few herbal supplements that are said to work( mutagenic s brand) … But these are all practitioner only .

    Is garlic detox a worthwhile way to go to eradicate Blasto?

    • Joanna Sochan December 30, 2016 at 7:56 pm - Reply

      I’m not sure what you mean by ‘garlic detox’ but taking garlic is one of the supplements/foods I recommend for parasite treatment. However, it’s unlikely that you’ll be able to eradicate Blasto by taking only garlic. The treatment needs to be more comprehensive and use other atiparasitic herbs/nutrients.

    Hi Joanna,
    I’ve been taking herbs for a month now prescribed to me by my naturopath. A week into taking them i experienced a spontaneous rash on my body which lasted a few weeks. I have never had this before starting the herbs or supplements. Could this be a reaction to the natural medicine?

    • Joanna Sochan January 10, 2017 at 7:41 pm - Reply

      Yes, it’s possible. Herbs and supplements can cause a release of toxins in the body (often it’s the aim of the treatment) that can overwhelm the main elimination channels – the gut, the kidneys, lungs and the skin. This can manifest as different symptoms in different people, in your case the body tried to eliminate excess toxins via the skin. This reaction can be avoided or minimised by reducing/adjusting the dose.

    Hi Joanna
    I was diagnosed with Blasto and D Frag last October, then was prescribed triple therapy. Symptoms of bloating, nausea, fatigue etc went away soon after and I was hoping finally I’d be healthy again. I had continued with Paleo type diet, L Glutamine, Bone broth as well as probiotics (Bioceuticals SB Floa activ ( 2 in morning, 2 in evening), digestive enzymes etc

    About a month ago my symptoms returned, this time with diarrhoea as well. I then had another PCR faecal test which was still clear, even though I had symptoms again. I’m unsure whether the parasites have returned, or the antibiotics have caused the issue
    My question is, should I have stopped taking the SB’s before my PCR test. I recall reading somewhere that the SB’s can give a false negative ) if so for how long should I stop before test?
    Also do you know of anyone on the Gold Coast who specializes in this area?

    many thanks

      I’m afraid I can’t offer specific advice via the blog, however, from experience it seems to me that your gut wall needs further repair and regeneration and the gut bacteria is likely out of balance as well – these two combined produce these sort of symptoms. It takes a body/ immune system a long time to settle after strong antibiotics, for some of my clients it takes 6 months+++ for the symptoms to settle.

      I don’t know of any practitioners based on the Gold Coast, I’m afraid.

    How important is it that the remedies are switched? I’ve been taking Candi-Bactin AR and BR for about a month now while also beginning to take things to support my immune system by way of T-Cell and Microphage Activity as well as things for my thyroid and for my vitamin C levels. I want to make sure we are on the right track to recovery and that I’m eating correctly. I eat a soup filled with Garlic onions leeks and celery, while Broccoli greatly bothers me and makes me bloated so I avoid that. I pretty much eat the same mix of meals including wild caught salmon, gras-fed beef, the soup, kale, organic turkey burgers, and that’s it. We just want to make sure we’re doing all of the right things or are at least remotely close. I would just like to make sure I’m rotating meals the right way and that I am to switch the herbal supplements when it is best. Is one month too long be taking the same essential oils and does the diet seem okay?

    Thank you very much and if you need to please feel free to respond to my email

      Rotating anti-parasitic remedies is very important as the parasites, especially Blasto, develop resistance after about 1-2 weeks. Therefore I usually have about three anti-parasitic remedies/options and alternate/ cycle them every week to 10 days. Restricting sugar/ carbohydrates is also of great importance.

    Hi Joanna,

    Thank you for this article! I keep reading that these parasites don’t respond to natural treatments so your article has given me hope! I do not want to be taking antibiotics. I’m sure I have had these bugs for 5+ years 🙁 but I’ve been pregnant or breastfeeding for the last 3.5 years, since before I found out I had them. I would love to contact you about treatment but have a few questions first. Can these parasites be safely treated while I’m breastfeeding? Or can at least the initial phases of your protocol be started while breastfeeding? I am absolutely exhausted and have trouble sleeping and concentrating as well as diarrhoea. Vitamins don’t really seem to help, and at the moment I am taking the S. Boulardii probiotic. Also wondering if it’s possible I could have passed this parasite to my son at birth? He’s a picky eater, has inconsistent stools and isn’t gaining any weight. Is it possible to safely treat a 2.5 year old for these parasites? Thank you so much for your time!

    Thanks for the article, much appreciated. I’m was a naturopath for years before having kids, where I specialized more in mens health, so I have limited knowledge about specific parasites and even moreso about children’s health. My 5 yr old son has verbal dyspraxia and is being diagnosed with ADHD despite young age. I’ve naturally done tests to show that he has extremely high blood levels of histamine (no history of any atopical or respiratory allergies/ issues, has low homocysteine and low ,v high SAH, v low SAM, neurotransmitter metabolite levels mostly within range though lower dopamine) which effectively suggests histadelia. Though methylation may be compromised with deficiency in enzymes, I suspect also involvement of high histaminergic diet, excess zinc, low methionine, as well as histamine production due to gut irritation from current parasite infection. Both children have been long infected with pinworms consistently throughout the year, but only recently has CDSA and PCR confirm higher levels of Blastocystis and low level dientamoeba with my son. Both children exhibit GIT symptoms consistent with these parasites, (as well as us parents), though with my son moreso, and I suspect it is adding to his histamine levels and in his words, making his “brain go crazy!”. He has low lactobacillis and high klebsiella as far as microflora findings.
    I’m about to start him on methionine, and have switched him to a low histamine diet, and would be looking at doing a lactobacillis high probiotic after a parasite eradication.
    I know that treatment would improve his start to school in a few weeks time, though I know treatment for histadelia/methylation improvement takes time. So I am actually considering the antibiotics to speed up eradication to give him to most effect on histamine reduction. I have no experience in treating children though so I’m unsure with a treatment protocol for herbal eradication or for post antibiotic protocol for a child.
    I’d be happy to have a phone/Skype/messenger consult with you if you think you would be able to help. My old naturopath friends also worked in other areas and are as equally unsure.
