When hopping continents or changing climate regions, your body encounters a vastly different ecosystem – especially of the microscopic variety. Between transportation to and from your destination, altered routines and sleeping habits, environmental and climate differences, and changes to food and eating habits, our immune systems are not at their peak when faced with invasive species. And unfortunately for us, exposure to these microbes doesn't just come from consuming tainted water or being bitten by a mosquito, it can also come from something as simple as walking with bare feet or swimming in a local watering hole. 

It is recommended that on top of using only bottled/purified water and plenty of insect repellant (where needed), travelers also make sure that their accommodations meet standards both in sanitation and water filtration as well. Be wary of street carts selling food, unwashed produce, and even “fresh squeezed” juices that may have been watered down with unfiltered water. 

However, avoiding possible exposure is not going to guarantee that you don’t bring home a little memento from your trip abroad. After all, there is very little to be done while aboard cruise ships, for instance - who are notorious carriers of a menagerie of contagions (such as norovirus). 

There are a variety of dietary supplements that can be used in both prevention as well as reparation.  

Clove Oil - has strong anti-microbial, antiseptic, anti-parasitic, and anti-inflammatory properties. Clove oil is known to be able to kill parasite eggs before they hatch.

Suggested Use: 1-2 drops of clove oil into an empty capsule, fill remainder with olive or coconut oil. Take 1 capsule 3 times per day.

Prescript Assist, Broad Spectrum Probiotic & Prebiotic Blend– has been proven* as a powerful remedy for a number of gut issues – traveler’s diarrhea included. 

Suggested Use: 2-5 capsules taken every 4-5 hours. Usage will depend on severity of issue, a higher amount being used in the beginning and tapering off once symptoms have subsided.

Carob Powder - helps soothe irritated or inflamed bowels.

Suggested Use: one heaping tablespoon in a glass of water (or applesauce) 2-3 times per day or as needed. 

Edible Earth– detoxifies gastrointestinal tract while aiding in the removal of parasites & their eggs. The clay creates a hostile environment for parasite reproduction, while helping balance gut microflora.

Suggested Use: one heaping teaspoon in a glass of water per day. (May need to increase usage depending on severity of issue. Always drink plenty of water when consuming internal clay.)

Black Walnut – one of the oldest remedies for killing parasites. 

Suggested Use: usage will depend upon which form of black walnut you choose to utilize, as this comes in tincture, powder and capsule form (as well as different types and parts of the plant).

Wormwood/Artemisia annua – reduces stomach pain & helps relieve anemia. It is believed that wormwood acts by weakening the parasites outer membrane. 

Suggested Use: usage will (again) depend on which form of wormwood you select, as this comes in tea, tincture, and capsule form.

Nascent Iodine - a powerful anti-microbial agent. Iodine is used commonly as a topical antiseptic as well as an emergency water purifier.

Suggested Use: can be added in small quantities to fluids of dubious nature prior to consumption. Add 4-10 drops, depending on contamination. Example: unfiltered water at a restaurant - 4 drops; lake water - 9-10 drops. Please remember that this is for temporary

Digestive Enzymes with Betain HCl - helps maintain proper stomach acidity which is a primary defense against ingested pathogens. 

Suggested Use: use according to selected product specifications. 

Grapefruit Seed Extract (GSE)* - contains natural anti-parasitic, anti-bacterial, and anti-fungal properties. 

Suggested Use: Add GSE liquid to empty capsule (1 drop per 10lbs of weight) and take 2-3 times per day. It is recommended that you do not exceed 60 drops per day.
*Grapefruit Seed Extract products have shown up on the radar in recent years as being unreliable in purity - in part due to companies who utilize chemical solvents in the extraction process. 


Some additional natural remedies for parasites include:






Coconut Oil

Oregon Grape


Olive Leaf

Diatomaceous Earth


One thing to keep in mind is that long term parasite infections will take longer to remedy than those that have only recently been contracted - so, take action immediately if you suspect the possibility that you may have picked up a "hitchhiker" along the way. 

As always, this list is not meant to replace your doctor's advice, nor should you embark on a treatment plan without first consulting your physician. The above listed remedies may or may not be suitable for your specific needs, diagnosis, or health status.
