There is nothing worse than discovering you are full of parasites, very sick, and your doctor doesn’t prescribe you anti-parasite medicine as I read happens to many people. It happened to me in 2011. I was more scared of parasites when I discovered the liver fluke in the above photo than the stage 3 cancer I had on 2 occasions, one following the fluke discovery. Still, make sure to see a doctor, and a doctor who studied additional training in Functional Medicine, Natropathy, or Traditional Chinese Medicine may be able to be more helpful.

In 2015 when I had parasites again another doctor prescribed me medicine, and though my medicare only covered 3-5 doses she gave me an additional script to order meds from Canada that were much cheaper than in the US. The bulk of the infection however was removed with herbs and fiber.

Often times doctors may not believe their patients have parasites as they are said to be rare in the United States. Patients are even gaslighted and called crazy. Other doctors have stated almost everyone probably has parasites. While conventional medications are often used to treat parasitic infections, certain herbs offer a natural approach to cleanse the body of parasites. Let’s explore the best herbs for fighting and removing parasites, their benefits, and precautions to consider.

Understanding Parasites

Parasites can enter our bodies through contaminated food, water, or contact with infected people or animals. While anyone can get parasites, some individuals are more susceptible, including those who travel frequently, consume raw or undercooked meat, or have weakened immune systems. Parasitic infections can lead to a range of symptoms, from mild discomfort to severe illness. Common types of parasites include giardia, flukes, cryptosporidium, tapeworms, pinworms, and head lice. Left untreated, parasites can cause serious health issues and even be life-threatening.

Understanding Intestinal Parasite Symptoms

Intestinal parasites can cause a broad spectrum of symptoms that are often overlooked or misdiagnosed because they closely resemble other common health issues.

Digestive Symptoms from Parasites

The most recognizable signs typically affect the digestive system. People may experience ongoing diarrhea or constipation, sometimes switching between both. Excessive gas, bloating, and stomach pain are frequent complaints, ranging from mild discomfort to intense cramping. Nausea often accompanies these issues.

Changes in bowel movements can provide important clues. You might notice food that appears undigested, unusual mucus, or in obvious cases, actual worms or worm pieces in stool. Some people develop unusual eating patterns, either feeling constantly hungry even after meals or losing their appetite entirely.

Whole-Body Effects From Parasite Infections

Parasitic infections often extend beyond stomach problems. Chronic tiredness and weakness are common because these organisms can steal vital nutrients from your system. Skin problems frequently develop, including unexplained rashes, hives, eczema-like conditions, or persistent itching. Nighttime anal itching is particularly associated with pinworm infections.

Mental and neurological effects can be surprising. Many people report increased anxiety, irritability, and sleep problems including insomnia, restless nights, or teeth grinding. Some experience “brain fog” – difficulty thinking clearly or concentrating. Physical symptoms like muscle aches, joint pain, and unexplained weight loss despite normal eating habits may also occur. Iron deficiency can develop when certain parasites cause internal bleeding.

In children, watch for unusual irritability, poor growth patterns, or sudden behavioral changes that don’t have other obvious explanations.

Important Considerations

Symptom patterns vary dramatically based on several factors: the type of parasite, how many are present, where they’ve settled in the body, and the person’s overall health and immune response. Some individuals carry parasites without any noticeable symptoms, while others become severely ill.

This variation makes diagnosis challenging because symptoms often mirror other conditions like irritable bowel syndrome, food intolerances, or chronic fatigue syndrome. The non-specific nature of these signs means parasitic infections are frequently overlooked during initial medical evaluations.

Herbs to the Rescue

Since ancient times, herbs have been used to combat parasitic infections. Here are some of the best herbs for parasites, backed by traditional use and, in some cases, scientific research:

Herbs with Broad Anti-Parasitic Potential

These herbs are frequently mentioned for their wide-ranging effects against various types of parasites.

Wormwood (Artemisia absinthium): This potent herb is highly valued for its ability to fight parasites, particularly tapeworms and other intestinal worms. Its effectiveness comes from compounds like thujone and sesquiterpene lactones, which can damage parasite membranes. Take for 10 days on (around the full and new moon when parasites are more active) and 5 days off.
Black Walnut (Juglans nigra) Green Hulls: The green outer hulls of black walnuts contain juglone, a powerful compound believed to be effective against a variety of worms and their larvae. It can help oxygenate the blood, which may also create an unfavorable environment for parasites.
Clove (Syzygium aromaticum): Often used alongside wormwood and black walnut in parasite cleanses, clove is rich in eugenol. This compound is thought to be particularly effective at killing parasite eggs, helping to prevent re-infection and breaking the parasitic life cycle.
Oregano (Origanum vulgare) and Oregano Oil: Known for its robust flavor, oregano also boasts significant antimicrobial and anthelmintic (anti-worm) properties due to compounds like carvacrol and thymol. Research suggests it may be effective against protozoa such as Giardia lamblia and Cryptosporidium parvum, as well as various intestinal worms.
Garlic (Allium sativum): A kitchen staple, garlic is revered for its broad-spectrum antimicrobial effects. Its sulfur-containing compounds, like allicin, are thought to contribute to its potential anti-parasitic activity against a range of intestinal worms and some protozoa.
Thyme (Thymus vulgaris): This aromatic herb contains thymol and carvacrol, similar to oregano, which offer potential anti-parasitic benefits. Studies have explored its effects against roundworm and tapeworm infections.
Turmeric: Curcumin in turmeric has anti-parasitic properties. It can aid in treating giardiasis, amoebiasis, and cryptosporidiosis. Turmeric can be consumed raw, cooked, or as a supplement, but excessive intake may cause digestive problems.

Herbs Containing Berberine

Berberine is a bitter-tasting alkaloid found in several plants, often recognized for its strong antimicrobial and anti-protozoal effects, particularly against organisms like Giardia and amoebae.

Goldenseal (Hydrastis canadensis): A popular herb, its roots contain berberine, making it useful in traditional remedies for various infections, including those caused by protozoa.
Barberry (Berberis vulgaris): Like goldenseal, barberry contains berberine and has a long history of use in traditional medicine for digestive issues and parasitic concerns.
Oregon Grape (Berberis aquifolium): Another berberine-rich plant, it’s often used for its antimicrobial and liver-supporting properties, which can be beneficial during a cleanse.
Goldthread (Coptis chinensis): This herb is a concentrated source of berberine and is a staple in Traditional Chinese Medicine for gastrointestinal infections.
Tree Turmeric (Berberis aristata): Also known as Indian barberry, it contains high levels of berberine and is used similarly to other berberine-containing herbs for its anti-parasitic properties.

Other Herbs with Noted Anti-Parasitic Uses

This list includes additional herbs that have been traditionally used or are being investigated for their roles in fighting parasites.

Papaya Seeds (Carica papaya): Used in traditional folk medicine, particularly in tropical regions, to treat intestinal parasites. Preliminary research suggests they may help in eradicating various parasites, with papain, an enzyme found in papaya, potentially aiding in killing worms.
Male Fern (Dryopteris filix-mas) root: Historically used to treat tapeworm infections. However, it requires extreme caution due to its potential toxicity to the liver and nervous system, so it’s rarely recommended for self-treatment today.
Tansy (Tanacetum vulgare) leaf: Traditionally used as a vermifuge (expels worms). Like Male Fern, Tansy also has potential toxicity and should be used with significant caution and under expert guidance.
Sweet Annie / Sweet Wormwood (Artemisia annua): Distinct from Artemisia absinthium, this plant is the source of artemisinin, a compound renowned for its effectiveness against malaria parasites. It also shows promise against other protozoa and some worms.
Curled Mint (Mentha crispa): A relative of common peppermint, preliminary studies have indicated its potential in relieving symptoms and eliminating Giardia and amoeba infections. Peppermint (Mentha piperita) may offer similar benefits.
Anise (Pimpinella anisum): Sometimes included in herbal parasite cleanses, anise has mild carminative (gas-reducing) properties and has been traditionally used for digestive discomfort often associated with parasites.
Grapeseed (Vitis vinifera): While not primarily known as an anti-parasitic, grapeseed extract is rich in antioxidants and is sometimes included in broader detox or cleanse formulas for its general supportive properties.
Grapefruit Seed Extract: (Citrus paradisi) Grapefruit seed extract has antimicrobial and antifungal properties, helping to fight off parasites. It can be effective against Giardia, Entamoeba, and Cryptosporidium. Grapefruit seed extract can be taken as a supplement or used in food.
Pumpkin Seeds (Cucurbita pepo): These common seeds contain cucurbitacin, a compound that may paralyze worms, making them easier to expel from the digestive tract. They are particularly noted for their effectiveness against tapeworms and roundworms. Pumpkin seeds are also being investigated for their potential anticancer properties.
Tongkat Ali (Eurycoma longifolia): Also known as Longjack, this herb has been studied for various properties. Some research suggests it might have antiparasitic effects, particularly against certain protozoa like Blastocystis.
Propolis: A resinous substance collected by bees, propolis boasts strong antimicrobial and anti-inflammatory properties. Studies have shown promising anti-parasitic activity, especially against certain protozoa and parasitic worms.
Neem (Azadirachta indica) leaves: Highly valued in Ayurvedic medicine, neem leaves are used traditionally for a wide range of ailments, including indigestion and various parasitic issues, thanks to their bitter compounds.
Onion (Allium cepa): Similar to garlic, onions contain sulfur compounds that give them their pungent flavor and may offer some traditional use against gastrointestinal parasites due to their mild antimicrobial actions.
Black Pepper (Piper nigrum) seeds: Traditionally used to improve digestion and nutrient absorption, black pepper is also sometimes included in herbal formulas for digestive issues, which might indirectly support the body in dealing with some parasitic concerns.
Ginger (Zingiber officinale) : Gingerol in ginger has antiparasitic effects. It can help eliminate parasites like giardia, amoebiasis, and cryptosporidiosis. Ginger can be consumed raw, cooked, or as a supplement, but excessive intake may irritate the digestive system.
Food-grade diatomaceous earth (DE) aids in parasite removal primarily through a physical, mechanical action. Its microscopic particles are incredibly sharp and porous, resembling tiny broken glass shards. When ingested, these particles cut and abrade the exoskeletons or protective coatings of parasites in the intestines, leading to their dehydration and eventual death, making them easier for the body to expel. Start with 1/4 teaspoon, increasing by 1/4 teaspoon every two weeks to 2 tablespoons for people 100-200 lbs or to 3 tablespoons for people 200-300 lbs. If you use too much in the beginning as I did you may have painfull constipation.

Colonix – A fiber used to sweep out or mop up parasites following use of the product Paranil (contains wormwood, black walnut, clove, and other herbs). They supply Kleri-tea a natural laxative as well if you purchase their bundle. Here is a picture of what people in support groups term “rope worm” which I believe impaired my digestion causing anemia and severe weight loss.

Benefits of Using Herbs for Parasites

Herbs have been used for centuries in traditional medicine to treat parasitic infections, and they offer several advantages over conventional medications:

Natural and gentle approach: Herbs are natural substances, often causing fewer side effects than synthetic drugs.

Reduced risk of drug resistance: Herbs are less likely to lead to drug resistance compared to conventional treatments.

Synergistic effects: Combining herbs can create synergistic blends, providing multi-target effects against parasites.

Immune system support: Some herbs, like neem, can strengthen the immune system, improving the body’s ability to fight off infections.

Precautions and Recommendations While herbs offer a natural approach to parasite elimination, it’s important to consider the following precautions: Proper dosing: Follow recommended dosages for herbal supplements to avoid potential side effects. Typically they are written on the bottle.

Medical advice: Consult a healthcare professional before using herbs, especially if you’re pregnant, breastfeeding, or taking medications.

Allergic reactions: Some herbs may cause allergic reactions, so it’s important to be cautious and consult a doctor if you have any allergies.

Interactions with medications: Certain herbs may interact with prescription drugs, so always check for potential interactions before use.

Excessive intake: Consuming excessive amounts of herbs can lead to digestive issues, so it’s important to stick to recommended dosages.

Whole food approach: Combine herbal treatments with a healthy diet and lifestyle changes to support overall wellness.

Foods in Traditional Chinese Medicine for Parasite Support

In TCM, food is seen as medicine, and dietary therapy plays a crucial role in maintaining health and strengthening the body’s ability to resist pathogens. Foods can help create an environment in the digestive tract that is less hospitable to parasites or support the body’s natural cleansing processes.

Garlic (Da Suan):
- As mentioned above, raw garlic is a powerful food-medicine that can be incorporated into the diet regularly for its pungent, warm, and antimicrobial properties.
Pumpkin Seeds (Nan Gua Zi):
- These can be eaten raw as a snack, particularly effective for children with pinworms or as a supportive food during a cleanse due to their ability to paralyze worms.
Pomegranate (Shi Liu / Fructus Granati):
- The fruit, especially the rind and root bark, has strong traditional uses against tapeworms in TCM. The fruit itself is nourishing and can be part of a healthy diet, while the more potent parts are used medicinally.
Pineapple (Bo Luo Mi / Ananas comosus):
- While not a historically classic TCM herb for parasites due to its origins outside traditional China, pineapple is recognized in modern TCM dietary therapy for its digestive benefits. Its enzyme, bromelain, is known to help break down protein structures, which can include the protective outer layers of certain parasites, making them more vulnerable and easier to expel. It’s considered to have a cooling and slightly sweet nature, aiding digestion.
Vinegar:
- Certain types of vinegar, commonly used in Chinese cuisine (like rice vinegar or black vinegar), are believed to create an acidic environment in the gut that can be less hospitable to parasites and may aid digestion.
Bitter Foods:
- TCM often recommends incorporating bitter-tasting foods to “clear heat” and “drain dampness” from the body, conditions that can foster parasitic growth. Examples include bitter melon (Ku Gua), dandelion greens, and certain leafy greens.
Fermented Foods:
- While not directly killing parasites, fermented foods like kimchi, fermented vegetables (like pickled cabbage or daikon), and traditional soy products (like tempeh or miso) support a healthy gut microbiome. A balanced and robust gut flora is crucial for strong immune function and overall gut health, creating an environment that discourages parasitic overgrowth.
Warm, Cooked Foods:
- TCM generally advises consuming mostly warm, cooked foods, especially during a cleanse or if digestive weakness is present. This is because raw and cold foods can “injure the Spleen Qi” (digestive energy), making the body more vulnerable and less efficient at processing and eliminating toxins and pathogens. Warm, cooked foods are easier to digest and support proper digestive function.

Foods Available in the United States That May Support Anti-Parasitic Efforts

These foods can be incorporated into a balanced diet to promote overall gut health and create an environment less favorable for parasites.

1. Alliums (Garlic & Onions)

Garlic (Allium sativum): Contains allicin and other sulfur compounds known for broad-spectrum antimicrobial (antibacterial, antiviral, antifungal, and potential antiparasitic) effects. Best consumed raw and crushed to activate allicin.
Onions (Allium cepa): Similar to garlic, onions contain sulfur compounds and flavonoids (like quercetin) that may have antimicrobial properties and support gut health.

2. Seeds & Nuts

Pumpkin Seeds (Cucurbita pepo): Contain cucurbitacin, an amino acid that may paralyze worms, allowing them to be expelled. Best eaten raw.
Flax Seeds (Linum usitatissimum): High in fiber and may help “sweep” the digestive tract, aiding in the removal of parasites and their waste. Also contains lignans with potential antimicrobial activity.
Almonds (Prunus dulcis): While not directly anti-parasitic, their fiber content and healthy fats support gut motility, which is beneficial for cleansing.

3. Fruits

Pineapple (Ananas comosus): Contains bromelain, a proteolytic enzyme that can break down proteins. This enzyme is believed to help digest the protective outer layers of some worms, making them vulnerable. Best consumed fresh.
Papaya (Carica papaya):
- Papaya Seeds: Contain carpaine, benzyl isothiocyanate, and benzyl glucosinolate, compounds that have shown anti-parasitic activity in studies, particularly against intestinal worms. Can be dried and ground.
- Unripe Papaya Fruit: Contains papain, another proteolytic enzyme similar to bromelain, which can break down parasitic proteins.
Pomegranate (Punica granatum):
- Fruit: The fruit itself is rich in antioxidants.
- Rind/Bark: Historically, the bark and rind have been used for their potent compounds (like pellertierine) effective against tapeworms, but these are not commonly consumed as food and should only be used under expert guidance due to potency.
Berries (e.g., Blueberries, Raspberries): Rich in antioxidants and fiber, supporting overall gut health and a healthy immune system.

4. Vegetables & Leafy Greens

Carrots (Daucus carota): High in beta-carotene, which supports immune function. Their fiber content helps maintain bowel regularity.
Beets (Beta vulgaris): Support liver detoxification and are high in fiber, aiding in regular bowel movements to expel waste.
Leafy Greens (e.g., Kale, Spinach, Swiss Chard): High in fiber, vitamins, and minerals, essential for a strong immune system and healthy digestion.
Bitter Greens (e.g., Arugula, Dandelion Greens, Endive): Bitter compounds can stimulate digestive juices (bile, stomach acid), which are crucial for proper digestion and creating an unfavorable environment for parasites.
Cabbage & Cruciferous Vegetables (e.g., Broccoli, Cauliflower, Brussels Sprouts): Contain sulfur compounds (glucosinolates) that support detoxification pathways in the liver.

5. Spices & Herbs (Culinary Use)

Turmeric (Curcuma longa): Contains curcumin, a powerful anti-inflammatory and antioxidant with documented antimicrobial properties that may include antiparasitic effects.
Ginger (Zingiber officinale): Known for its digestive benefits, ginger can help relieve nausea and promote gut motility, which aids in expelling parasites.
Cayenne Pepper (Capsicum annuum): Its heat is believed to create an inhospitable environment for parasites and stimulates circulation and digestion.
Oregano (Origanum vulgare): Contains carvacrol and thymol, potent antimicrobial compounds. Culinary oregano can be used, and the more concentrated oil is also used therapeutically (but consult a professional).
Thyme (Thymus vulgaris): Contains thymol, which has known antiseptic and anthelmintic properties.
Clove (Syzygium aromaticum): Contains eugenol, found to be effective against parasite eggs and larvae.

6. Fermented Foods

Sauerkraut, Kimchi, Pickles (naturally fermented): Rich in probiotics (beneficial bacteria) which help maintain a healthy gut microbiome. A strong, diverse microbiome is a key defense against opportunistic parasites and helps to restore balance after a parasitic challenge.
Kefir, Yogurt (with live active cultures): Provide beneficial bacteria to support gut health.

7. Other Supportive Foods

Coconut Oil (virgin, unrefined): Contains medium-chain triglycerides (MCTs), particularly lauric acid, which have antimicrobial properties.
Apple Cider Vinegar (raw, unfiltered): Creates a more acidic environment in the stomach and gut, which can be inhospitable to parasites and aids digestion.
Bone Broth: Rich in amino acids and collagen, which can help heal and repair the gut lining (often compromised by parasitic infections).

Dietary Strategy: A common strategy involves a period of avoiding sugar, processed foods, and refined carbohydrates, as these can feed parasites and yeast. Simultaneously, increasing intake of the foods listed above, along with plenty of water, can create a less hospitable environment and support elimination.

Remember, always seek professional medical advice for parasite treatment.
