Pure All Natural Ingredients of FourGuard Herbal Liquid Herbal Parasite Cleanse for Dogs and Cats

Gentian Root--is found in the highest pastures of the Alps and the Himalayas. Because of the extreme cold temperatures, roots take from seven to ten growing seasons to mature. This herb has been used in European medicine for the 2200 years since its discovery by its namesake, Gentius, King of ancient Illyria (180-167 BC). Herbalists agree that this herb is one of the most powerful yet safe natural dog and cat dewormers known.

Black Walnut Hull--has historically been used as an antiviral, antifungal, and anti-parasitic. Studies show this powerful ingredient can eliminate a wide range of internal parasites and symptoms of dog worms and cat worms without any harmful effects.

Cloves--have been used for culinary and medicinal uses since antiquity. The distinctive aromatic oil is derived from the dried buds of this evergreen which is native to the tropics. Cloves are a favorite among medicinal herbalists when used as a drugless anthelmintic: defined as any medicine used to destroy parasitic worms. With parasitic worms gone, the symptoms of dog worms and cat worms will also be gone.

Papaya Leaf--is taken from the small tropical tree that produces the large, delicious fruit. The leaves of papaya are used as a vermifuge; that is, to remove intestinal worms. The leaves of the papaya are invaluable because of their high content of tannins. These tannins protect the intestine from re-infestation as its proteins coat the lining of the intestinal wall so that worms can no longer attach themselves.
NOTE: Refrigerate LIQUID after opening.
FAQs for FourGuard Herbal Cleanse
Yes— the product is formulated specifically for pets. FourGuard is free of toxic herbs like wormwood (which is especially important for cats). Follow dosage instructions carefully for your pet’s weight and species.
Common signs include:
-
Worms in stool or vomit
-
Scooting or licking the rear
-
Weight loss despite a good appetite
-
Diarrhea, vomiting, or bloating
-
Dull coat or itching
-
Vet-confirmed parasites via stool test
Side effects are rare with gentle herbal formulas but may include mild detox symptoms like loose stool, fatigue, or increased thirst. These usually pass quickly.
No, veterinary deworming is not permanent in pets.
Here's why:
-
Reinfection is common: Pets can be re-exposed to parasites shortly after treatment—through contaminated soil, water, food, feces, or infected animals.
-
Dewormers don't prevent future infestations: Most veterinary dewormers kill existing worms but don't offer ongoing protection.
-
Lifecycle of parasites: Some parasites have complex lifecycles that allow dormant stages to reactivate after initial treatment.
Feeding a clean, whole-food diet with probiotics and adequate hydration helps the body eliminate parasites more effectively. Avoid processed foods during the cleanse if possible.
