Are parasites wrecking your gut? The best parasite cleanses and how they work, per experts

Can’t figure out why you’ve been feeling off?

If you’ve been dealing with fatigue, bloating, brain fog, or digestive drama, there could be a hidden cause that you haven’t considered yet: parasites. Yes, little creepy-crawlies could be whirling around in your gut, and a parasite cleanse may be your best bet for getting rid of them.

They may not be pleasant to think about, but they’re far more common than many of us realize, even in developed countries. Parasite exposure can occur in several settings: while swimming, traveling, eating undercooked seafood or meat, drinking contaminated water, and even from living with pets.

The CDC estimates that 60 million people in the US are chronically infected with Toxoplasma gondii, and there are at least 1,000 hospitalizations per year. Even more people could be at risk due to the potential for underreporting, misdiagnosis, and the lack of interventions to prevent or treat disease.

“I wish more people knew what to look for,” shared Sinclair Kennally, a certified natural health professional, clinical nurse coordinator, and founder and CEO of Detox Nation. “It’s not just bloating or digestive drama… I’m talking skin issues, intense sugar cravings, brain fog, anxiety, irritability, even teeth grinding, and insomnia.”

The good news is that most parasitic infections are treatable. Beyond pharmaceutical interventions, several herbal, at-home parasite cleanses are available from reputable brands like Touchstone Essentials, Anima Mundi, and BIOptimizers.

What is a parasite cleanse?

Parasite cleanses are designed to help kill and expel parasites from the body. Most natural parasite cleanses involve ingesting a combination of herbs, as well as making some dietary changes to help support the detox process.

“Herbs have been used for centuries in many cultures to help remove toxins and unwanted microorganisms,” said Eddie Stone, the founder and CEO of Touchstone Essentials. This leading wellness brand offers natural detox solutions.

Stone highlighted a few key ingredients in parasite cleanses — such as Barberry Root, which supports digestion and a healthy gut lining, Organic Clove Bud, which helps disrupt microorganisms, and Organic Wormwood leaf, which has also been used for centuries to help protect the gut against invaders.

“With a healthy gut, the body can more easily use its natural defenses against any invaders,” Stone added. “Cleansing the gut eases digestion and can help the whole body gain a more balanced state.”

Touchstone Essentials’ Para-Shield is an exclusive herbal blend that claims to help flush out freeloading microscopic invaders. The formula, packed with well-researched ingredients like Black Walnut Hull, Clove, and Wormwood, is blended to create a hostile environment for unwanted internal parasites. Bonus: it’s also loaded with antioxidant-rich ingredients like Barberry Root, Ginger, and Yuzu to give your immune system a serious boost. Reviewers are generally very pleased with the ease of use, taste, tolerance, and benefits, which can be seen in as little as the first week of use. Some users mentioned reduced bloating, stress, and sugar cravings, while others noted that Para-Shield effectively eased their digestion issues.

New York Post Review: I was skeptical about parasite cleanses when I first read about them. But, after doing my research and speaking with experts, I began to understand how the different ingredients work and what to look for. Touchstone Essentials offers a gentle tincture that supports detoxing and targets a variety of unwanted parasites with organic herbs like Walnut Hull, Wormwood, and Clove. This formula has a kick, but I was quite impressed with the flavor. It’s light, sweet, and dilutes easily (you can plop the drops in your mouth or drop them in a glass of water). You do have to take it twice a day on an empty stomach, so timing your meals is important. Some more frequent trips to the bathroom are also to be expected. But other than that, I didn’t experience any dramatic detox side effects. By the end of the three weeks, I noticed I was craving fewer sweets and felt and looked a bit less bloated. I also began to understand what reviewers meant when they said that their cleanse helped them feel more like themself. A little less stressed. A bit lighter. It’s a great gut and whole-body reset when done slowly and safely. Still, I tell everyone to consult their physician before starting any new health routine.

Perhaps you’ve seen ParaGuard pop up on your social media, or you may have seen it climbing the charts on Amazon. The Zahler formula is a very popular choice, with over 20,000 Amazon purchases in the last month and almost 30,000 reviews. ParaGuard blends herbs like Wormwood, Garlic Bulb, Pumpkin Seed, and Clove — traditionally used for supporting gut health and cleansing.

Some reviewers dislike the strong flavor, but agree that it dilutes easily with water or juice.

Length of Cleanse: Take 1/2 teaspoon (2.46 mL) 2 to 3 times daily.

These ingredients target both GI detox and colon detox, promoting regularity, while also claiming to support sleep patterns and reduce hyperactivity. Para Patrol features advanced flavor masking technology to make it more appealing for picky kids and mixes easily into smoothies, juices, and yogurts. While this tincture was formulated for children, it’s very important to consult a physician prior to use. Side effects have been reported, and certain ingredients could cause allergic reactions, especially for kiddos with nut allergies.

Crafted by clinical herbalists in Brooklyn, Anima Mundi’s digestive supplement is a sustainably sourced formula with many gleaming reviews. While Amargo may not be advertised as a parasite cleanse, the blend certainly offers some ingredients that support bile release and promote liver detoxification, including Chanca Piedra, Burdock, Dandelion Root, Milk Thistle Seed, Oregon Grape Root, Fresh Orange Peel, and Ginger. For anyone who is particularly sensitive to Wormwood, Amargo is a great alternative that still packs in plenty of barks and roots to promote liver cleansing. The formula is very high potency, with a 10:1 ratio of herbs to liquid. Reviewers still find the flavor pleasant, noting that the alcohol burn present in most bitters is much milder in this formula.

The capsule form may not be ideal for all users, especially considering the serving size (2 pills, up to 3 times per day). However, some users mention that pills are easier to travel with. Plus, the visible results could be worth it.

Length of Cleanse: Since some parasites lay eggs, it is recommended to cleanse on or around the Full Moon, as this is the period when eggs typically hatch. For best results, begin the cleanse 5 days before the full moon, and continue on to complete 10 full days. | Safety: The Food Over Drugs Parasite Formula could cause detox symptoms and interfere with other medications; it is not recommended for pregnant or breastfeeding women

How to do a Parasite Cleanse FAQs

For answers to all your questions about the benefits and risks of parasite cleanses, the Post consulted several health and wellness experts with years of experience in safe and effective detoxing.

What are the signs and symptoms that someone might need to do a parasitic cleanse?

“While no one wants to imagine they have creepy-crawlies in their gut, parasites are more common than you think,” shared Eddie Stone, the founder and CEO of Touchstone Essentials. “Signs of parasites include a myriad of digestive problems that can often be confused with other common ailments.”

He explained that symptoms can manifest as unexplained constipation, diarrhea, gas, or bloating. Fatigue and exhaustion are also common, as parasites can drain energy by consuming nutrients meant to nourish the body.

“Other symptoms may include itchiness or skin irritation, teeth grinding at night due to toxins affecting neurotransmitters, and a constant feeling of bloating or fullness,” he noted.

What are some of the benefits of doing a herbal cleanse?

According to Stone, there are several benefits that come from a successful parasite cleanse.

“After cleansing, some people report healthy and regular digestion, reduced hunger and cravings, and improved energy levels,” he explained. “A cleanse may reduce bloating by addressing digestive issues such as slow or inconsistent digestion, toxins, and stress, allowing the gut to reset naturally.”

Beyond cleaning the gut, Stone also has suggested that these herbs can further aid natural detoxification by supporting other organs, including liver and kidney function. Some users even report feeling more like themselves, with brain fog vanishing.

“In addition, those that suffered from skin irritation, lethargy, or brain fog report feeling more energy, clarity, and calmer skin,” he added.

What is in a herbal cleanse?

Stone has highlighted some of the key ingredients used in Para-Shield as well as other popular herbal parasite cleanses:

• Organic Clove Bud: Contains eugenol, highly effective at disrupting microorganisms.
• Organic Ginger Root: Soothes digestion and promotes a healthy microbiome.
• Organic Black Walnut Hull: Features juglone, which helps eliminate unwanted microorganisms.
• Barberry Root: Supports healthy digestion and supports a healthy gut lining.
• Organic Wormwood Leaf: Used for centuries to help protect against gut invaders.
• Organic Sweet Wormwood Leaf: Contains artemisinin to fight against microorganisms.

What are some of the risks of doing a herbal cleanse?

If you’re interested in doing a parasite cleanse, there are some risks you should know about.

Most parasite cleanses are not recommended for pregnant and breastfeeding women, as well as young children. Some parasite cleanses include herbs (such as Wormwood and Black Walnut), which could cause allergic reactions, especially in those with severe nut allergies.

“Done right, herbal cleanses are very safe. That said, die-off is real. When parasites die, they release toxins. That can mean fatigue, headaches, mood swings, skin flare-ups… all temporary, but not always fun,” explained Sinclair Kennally, founder and CEO of Detox Nation

To avoid die-off symptoms, Kennally suggests going at a pace your body can handle and adjusting the dosage as needed. If symptoms persist, it’s best to stop the cleanse.

How common are parasites? Do they affect people in other countries more than in the U.S.?

“This is one of the biggest myths I fight every day,” admitted Kennally.

Kennally explained that parasite exposure can happen in a variety of settings, through international travel, factory farming, undercooked food, pets, and poor food handling standards.

“We’ve been told parasites are only an issue ‘over there’ — in developing countries — but the truth is, they’re incredibly common here in the U.S., too. We just don’t talk about them, test for them, or treat them well,” she explained. 

She also pointed out that many other countries include parasite work in routine medical care. In the U.S., some physicians may be less inclined to link relevant symptoms to parasite exposure.

Do you recommend fasting, juicing, or a specific diet during the cleanse?

“You don’t need to live off lemon water to make a cleanse work, but you do need to stop feeding the parasites. They thrive on sugar, processed carbs, and dairy,” Kennally warned.

During a cleanse, she recommends eating a nutrient-dense, anti-inflammatory diet with lots of vegetables, clean protein, bone broth, bitter greens, and good fats. Drinking plenty of water will also help the body flush out toxins and help prevent dehydration during detox.

“And yes, I’m a fan of intermittent fasting when appropriate,” she shared. “It gives your gut a break and accelerates results, but only if your energy and blood sugar can handle it. Full-on juice fasts or extreme calorie restriction? Usually not helpful.”

Are all parasites bad for you?

Adriana Ayales, the Owner and Herbalist of Anima Mundi, a Brooklyn-based apothecary, believes our relationship with parasites is complex and evolutionary.

“It’s important to know that not all parasites are harmful,” shared Ayales. “In fact, studies on helminthic therapy (using controlled parasitic exposure) suggest that certain parasites can help prevent autoimmune diseases by modulating inflammatory responses.”

She has pointed out that parasites have coexisted with humans for millennia and have shaped our immune systems. However, changes in diet, microbiome diversity, and toxin loads have tipped the balance, making it more important to regulate parasite exposure.

“So, while parasites can be essential to immunological balance, an unmonitored or high burden —especially in the presence of a compromised gut or liver — some may require periodic cleansing and terrain support,” Ayales explained.

What’s the difference between a herbal cleanse and a pharmaceutical approach?

According to Ayales, allopathic and traditional systems of medicine tend to offer different tools for treating parasite infections, both with the same goal of restoring balance. 

“Conventional medicine typically relies on laboratory diagnostics followed by pharmaceutical antiparasitics such as albendazole, ivermectin, or metronidazole to target specific pathogens, noted. “These may be supported with liver protectants and medications to manage inflammation or die-off reactions.”

In contrast, herbal cleanses typically incorporate a variety of different plant-based ingredients that are believed to target parasites, support elimination, and balance the gut. She added that these herbs are often paired with dietary changes, detox support, and sometimes, spiritual practices.

“Traditional healing systems — such as Ayurveda, Traditional Chinese Medicine, and Amazonian plant medicine — use time-honored herbal protocols involving botanicals like wormwood, black walnut, clove, neem, and mimosa pudica to target parasites at various life stages,” Ayales said.
