If you think parasites only happen to people who travel abroad or eat raw meat, think again. Millions of people in North America are carrying unwanted guests: tiny organisms that steal nutrients, release toxic waste, and wreak havoc on everything from digestion to mood.
Even if you eat relatively clean, have good hygiene, and take care of your body, parasites can still find a way in. They can live in contaminated produce, undercooked food, unfiltered water, or even on pets. Once they settle into your gut, they feed, multiply, and throw your whole system off balance.
The good news? You can help your body eliminate them naturally and safely without harsh pharmaceuticals.
Below, I’ll walk you through 10 warning signs your body may be full of parasites, followed by 10 natural, research-backed ways to help eliminate them and strengthen your body’s defenses.
10 Warning Signs Your Body Is Full of Parasites
Most people assume parasite infections only happen in developing countries, but studies show millions of people in North America carry undiagnosed parasites without realizing it. These organisms thrive silently in the gut, feeding off nutrients and releasing toxic waste that can disrupt everything from digestion to mood and immunity. Here are 10 key signs your body may be overloaded with parasites:
- Unexplained Fatigue
Persistent tiredness, even after a full night’s rest, can signal that your body is fighting a chronic infection. Parasites steal nutrients like iron and B12, leading to low energy and burnout. - Digestive Distress
Gas, bloating, constipation, or diarrhea, especially if symptoms flare after eating, may be a red flag for parasitic activity in the intestines. - Uncontrollable Sugar or Carb Cravings
Many parasites feed on glucose. Their presence can drive intense cravings for sweets and processed carbs as they manipulate your body’s appetite signals. - Skin Issues
Acne, eczema, hives, or unexplained rashes can indicate your liver and immune system are overloaded trying to eliminate parasite toxins. - Bruxism (Teeth Grinding)
Grinding your teeth at night may result from the nervous system’s response to parasites releasing neurotoxins. - Unexplained Weight Changes
You may gain or lose weight without changing your diet. Parasites can rob your body of nutrients or trigger inflammation that alters metabolism. - Sleep Problems and Restlessness
Parasites are most active at night. If you often wake between 2–4 a.m. or struggle with insomnia, your body might be reacting to their nocturnal activity. - Joint or Muscle Pain
Some parasites migrate to tissues and joints, causing inflammation and pain that mimics arthritis or fibromyalgia. - Mood Swings and Anxiety
Gut parasites can disrupt neurotransmitter balance, especially serotonin, leading to irritability, depression, or anxiety. - Frequent Illness or Weak Immunity
Chronic infections, allergies, or slow recovery times suggest parasites may be depleting your immune defenses.
How to Get Rid of Parasites Naturally
Here are 10 natural ways to eliminate parasites you almost certainly have!
1. Use Anti-Parasitic Herbs Backed by Research
Several herbs have well-documented antiparasitic properties, many used traditionally for centuries.
Modern research confirms their efficacy against parasites like Giardia, Blastocystis, and Ascaris.
Some of the most effective include:
- Wormwood (Artemisia absinthium): Shown to paralyze intestinal worms and interfere with their metabolism.
- Black Walnut Hull: Contains juglone, a compound toxic to many intestinal parasites.
- Clove: Contains eugenol, which helps destroy parasite eggs and larvae.
- Thyme and Oregano: Both contain thymol and carvacrol, which have been proven to inhibit parasite growth.
Try a tincture like Para Care Cleanse, which combines these herbs synergistically and is free of alcohol and sugar.
2. Support Detoxification Pathways
When parasites die, they release toxic waste that can overload your liver, kidneys, and lymphatic system.
Support these pathways with hydration, dry brushing, rebounding, and herbal teas like:
- Nettle leaf
- Milk thistle
- Ginger root
- Lemon balm
You can also try ParaX by Cymbiotika, which blends targeted herbs and amino acids to enhance liver detox and microbial balance while you’re cleansing.
3. Boost Immunity with Papaya Seeds and Enzymes
Papaya seeds contain benzyl isothiocyanate, a compound that helps kill intestinal worms. In one randomized controlled study, 71% of children who consumed papaya seed extract were cleared of parasites within a week.
Papaya enzymes also help break down the biofilm parasites use to protect themselves.
Blend fresh papaya seeds into a smoothie or mix them with honey (about 1 tablespoon per day for a week).
4. Optimize Liver Function and Bile Flow
Your liver and bile are natural parasite deterrents. Bile salts are toxic to many types of worms. But if your liver is sluggish, bile flow slows, giving parasites room to thrive.
Support detoxification by consuming:
- Dandelion root and greens
- Burdock root
- Beets and beet juice
- Lemon water
These foods and herbs enhance bile production and flow, helping your body digest fats properly and flush out parasitic waste more effectively.
5. Eat More Raw Garlic and Onions
Garlic contains allicin, a sulfur compound proven to kill over 20 types of parasites in lab studies, including Giardia and Entamoeba histolytica. Onions offer similar benefits and support detoxification enzymes that help your liver clear out waste left behind by dying parasites.
To get the full effect, eat raw garlic daily. Crush or chop it and let it sit for 10 minutes before consuming to activate allicin. You can also add it to fresh juices or dressings if the raw flavor is too strong.
6. Use Oil of Oregano
Oil of oregano is a powerhouse antimicrobial.
In a clinical study published in Phytotherapy Research, 77% of patients with intestinal parasites became parasite-free after taking oil of oregano capsules for six weeks.
Its active compounds, carvacrol and thymol, destroy protozoa and worms while supporting healthy gut flora.
Take 2–3 drops of therapeutic-grade oil in water or use capsules like Oreganol P73, taken with meals.
7. Support Your Gut Microbiome with Probiotics
A balanced gut flora is your first line of defense. Beneficial bacteria outcompete parasites and help maintain an environment they can’t survive in.
Studies have shown that probiotics like Lactobacillus and Bifidobacterium strains reduce the survival and attachment of intestinal worms and protozoa.
Look for a multi-strain probiotic from a reputable brand such as SEED, which supports gut resilience and immune balance.
Pro tip: Eat fermented foods like sauerkraut, kimchi, or coconut yogurt daily, and take a quality probiotic supplement for deeper repair.
8. Reduce Sugar and Processed Foods
Parasites thrive on glucose and processed carbohydrates. Diets high in sugar suppress immune function, feed bad bacteria, and create an acidic internal environment that allows parasites to flourish.
Eliminating refined sugars, alcohol, processed snacks, and white flour products can starve parasites and make natural treatments more effective.
Focus instead on fruits, vegetables, legumes, and whole grains that stabilize blood sugar and support gut repair.
9. Incorporate Pumpkin Seeds
Pumpkin seeds aren’t just a folk remedy. They’ve been clinically proven to paralyze and expel intestinal worms, including tapeworms and roundworms. They contain cucurbitacin, a compound that interferes with parasites’ ability to attach to intestinal walls.
A 2016 study published in International Journal of Molecular Sciences found pumpkin seeds highly effective against Hymenolepis nana (dwarf tapeworm) infections.
Eat ½ cup of raw, soaked pumpkin seeds daily, or blend them into smoothies for a gentle but effective cleanse.
10. Stay Consistent and Rebuild
The most overlooked part of parasite cleansing is the rebuilding phase.
After a cleanse, you must repopulate your gut with beneficial bacteria, repair the intestinal lining with nutrients like zinc, L-glutamine, and aloe vera, and continue eating anti-inflammatory foods.
Parasite cleansing isn’t a one-time fix; it’s about creating a terrain that parasites simply can’t survive in. Once you do that, they don’t come back.
Optional Supportive Practices
If you want to go deeper, these extra habits can amplify your cleanse:
- Stay hydrated with at least 2–3 liters of filtered water daily to flush toxins.
- Use castor oil packs over your liver to boost lymphatic drainage.
- Infrared sauna or sweating helps release toxins through the skin.
- Activated charcoal or bentonite clay can bind and remove parasite waste.
- Gentle colonics or enemas (done safely) can support elimination if you’re constipated.
When to Seek Professional Help
Even though natural methods are powerful, not every parasite infection can or should be handled at home. Some parasites burrow into tissues or organs and require medical treatment.
If you experience severe abdominal pain, unexplained anemia, fever, or visible worms in stool, get tested by a healthcare provider. Stool analysis, PCR testing, or bloodwork can confirm infections that require antiparasitic medication.
Combining medical treatment with natural approaches (diet, herbs, probiotics) is often the most effective way to clear infections and rebuild long-term resilience.
Maintaining a Parasite-Resistant Body
Once you’ve completed a cleanse, your focus shifts to prevention and maintenance.
Here’s how to stay parasite-free:
- Eat a clean, mostly plant-based diet rich in fiber and leafy greens.
- Rotate probiotic and prebiotic foods to support gut health.
- Avoid raw or undercooked meats and unfiltered water.
- Wash produce thoroughly (especially imported fruits).
- Wash your hands after touching pets or gardening.
- Do a mild herbal maintenance cleanse once or twice per year if needed.
A well-nourished, oxygenated body simply doesn’t attract parasites the way a sluggish, acidic one does.
The Bottom Line
Parasites are far more common than most people realize, and they can wreak havoc on your health without obvious warning signs. But with the right diet, herbs, and lifestyle adjustments, your body is fully capable of expelling them naturally.
By focusing on gut health, liver support, and proven anti-parasitic foods like garlic, pumpkin seeds, oregano oil, and probiotics, you can restore balance and finally feel the clarity, energy, and lightness that come from a truly clean body.








Oil of oregano can be a very effective way to treat parasites, but be careful with the strength of the oil you use and how you use it. I used an 85%+ pure OO added to water with the intention to kill parasites and boost my immune system. Instead, I just burned my mucosal lining from throat to stomach. Awful!
Make sure your OO is diluted with OIL (not water, not lemon juice). Or else be extra safe and use a capsule such as those by Gaia Herbs.
Thanks for the input Toffler!
I’m assuming it would be OK to use (as a dairy substitute) almond milk? Thanks so much for this article.
Absolutely! Almond milk is a great substitute, especially if you can make it yourself using raw almonds 🙂
Carly makes some good points. I'd like to add a few things:
Read Hulda Clarks' books – she speaks extensively about different parasite infections in humans, their symptoms and what you can do to reduce or remove them. Know that it is nearly impossible to be parasite free completely.
Thinking that becoming vegetarian or vegan will shield you from getting parasites is a dangerious myth. It is usually the raw, not properly washed and disinfected leafy greens that carry many parasitical eggs which people happily choomp or drink down thinking they are so healthy for doing so. Yes, of course raw meats are just as much a culprit, but know that vegetables are just as guilty if not handled properly. And by "properly" I don't mean washing for a few seconds under the tap. Even soaking is not enough. At the very least soad for a good five minutes in a water/vinegar (20% solution!) mix – and this, AFTER you've already washed your veggies/fruit.
You also need tremendous amounts of high quality fats, real salt, and super clean water as a basic foundation for a strong physical body. Getting rid of parasites is not always so easy. You often need to do a good deworming (which in practice can take several weeks to months) and do so at least once ore twice a year depending on your personal circumstances. Parastical infections are not uncommon, in fact, everyone reading this likely has many different kinds of parasites roaming around their bodies doing damage.
Don't freak out about these things. They are a fact of life that comes with having a body. Educate yourself as much as possible and do what you feel is best for you and your personal circumstances. If you still aren't feeling great, then keep searching for answers.
Dear Yvette, This was so helpful and ‘commonsensical’ to me. I have been dealing with various parasites for a while now and was beginning to get disheartened. can you elaborate on ‘tremendous amounts of high quality fats.’
Many thanks and good wishes.
Pam
Hello Pan, my apologies for not responding sooner, but I only just now saw your comment. High-quality fats help both build and protect one's body. If you are open to eating meat products, then organic (if possible) lard, or pig fat, is good as is fat from other healthy animals such as duck. I know that most people reading this will crucify this suggestion since we are brainwashed into thinking that fat is bad, especially lard. However, this is simply not true. Sure, poor quality fats are indeed, bad for us, but that doesn't mean we should leave out fat completely. Rather, be more selective. People who eat high-quality fat and even lots of it do not gain weight, and generally, tend to have more energy. The same goes with sugar. We actually do need sugar. It is a major source of energy, but like fat, we need to be selective about what type we ingest. Preferably reduce refined sugars and stick with natural sugars. In order for the liver and gall bladder to do a great job of making digestive juices, which help keep your digestion strong, and thus your ability to keep your immunity up, you need to have good fats in your diet. Most seed and nut oils/butters are good, as is coconut oil. Cold pressed, non-refined, raw, organic are best if possible.
Parasite cleanses need to be cyclical.
Don't despair, it takes time and dedication to reducing one's parasite load after it has overrun the body. Hulda Clark has a great natural protocol which is a combination of black walnut, clove, and wormwood. Unfortunately, in most cases, this is not enough. Taking this regularly IS very helpful, but to take back the control you may need more options.
If you know a vet, have a frank chat with them and ask what they use to treat various parasite infections in their animals, how often they think they should be treated and where and how they believe animals get infected in the first place. I guarantee it will be a very enlightening conversation.
Some countries understand parasite infection in humans to be a fact of life. They make it easy to walk into any pharmacy and ask for a deworming medication, even without a prescription. In North America, this is not yet the view and it can be challenging to get appropriate medical attention. What makes it even more difficult is that the typical lab tests are notorious for coming back negative, when in fact, the person is positive for parasites.
If you feel you have parasites, don't give up Pan, keep searching until you find ways to get the help and support you need.
im on day 12 of my juice fast to rid myself of the constant stomach pain parasites have been causing me. been drinking lots of vegetable juices i make at home but on day 10 i sadly drank a lot of store-bought juice with lots of added sugar 🙁 and soon after felt the ever so familiar pain of the parasites going crazy. i got back on the fresh juices only, but i am wondering, did i completely scrap the first ten days of my fast, and i should start over, or just keep going. hoping to do 21 days but if i dont get rid of the parasites i guess ill go longer.
thanks, benjamin
Just keep going. Don't let the breaking of the fast get you down, just pick back up where you started 🙂
