These are optional cleanse directions based on the protocols of Dr. Hulda Clark.

If you need help to clarify the cleanse directions, please give us a call, but please note that we cannot give medical advice of any sort.

Refer to these directions for the original Parasite Cleanse, Vegetarian Parasite CleanseParasite Cleanse with Freeze Dried Black Walnut HullParasite Cleanse Plus, and Parasite Cleanse & Maintenance Program.

The Parasite Cleanse was always the first cleanse Dr. Clark had people take in her clinic. This is the most effective of Dr. Clark’s protocols. Upon Dr. Clark’s insistence, the Parasite Cleanse features GREEN Black Walnut Hull made from the unripe green hulls which contain higher concentrations of the active compound juglone.

Dr. Clark designed the Parasite Cleanse for maximum effectiveness without compromising safety. This is why she designed the 18-day protocol; it enables your body to slowly get used to these extraordinarily potent herbs.* 

To get the greatest possible benefits from the Parasite Cleanse, please consider the following carefully:

The Digestive Aid Cleanse works synergistically with the Parasite Cleanse. For even better results take these two programs over the same time period. You will gain on two fronts at the same time; while the Parasite Cleanse will balance foreign organisms systemically throughout your body, the Digestive Aid will optimize your digestion in both the stomach and intestines.

To gain even more benefits from your cleanse, stay on the weekly Parasite Cleanse Maintenance Program for a minimum of 4 weeks to a year. The benefits are cumulative as the Maintenance Program continues to minimize the effect harmful microorganisms have due to continuous re-exposure. Dr. Clark believed that in order to gain 100% of the benefits of the cleanse, it was best to stay on the Maintenance Program indefinitely. This helps free up your body’s energy for issues that need attention rather than relentlessly fighting microorganisms.*


The Parasite Cleanse supports the body’s defenses with natural compounds that discourage the proliferation of foreign organisms known to occupy the human body. This process helps balance your body and its microorganisms. It is ideal for pet owners and people returning from traveling abroad.*

Our Black Walnut Hull Tincture is a good example of our adherence to purity and potency. First, it is potent because we use large amounts of the unripe, green hulls from the Black Walnut tree. The average tincture strength (hull to grain alcohol) is 1:0.68. Second, in our experience, Black Walnut Hull that is green has almost up to 10 times the amount of juglone, an essential ingredient in the tincture. Other manufacturers do not go the extra mile and offer only brown or black tincture. When a tincture is brown or black, it contains much less juglone. Dr. Clark Store guarantees unopened bottles of the tincture to be green at least two years past the manufacturing date. Once open, the tincture will start to oxidize and turn brown and then black. At this stage it contains much less juglone, so you may have to double the dose you take.*

Parasite Cleanse Plus

Follow the chart above for Black Walnut Hull, Super W Blend, and Cloves. Take Raz-Caps and Tape ParaKil Oil as follows either during the 18-day cleanse protocol or after you have completed the 18-day cleanse protocol.

Parasite Cleanse Maintenance Program

The Parasite Cleanse Maintenance Program delivers the greatest benefits if you take it on a consistent basis.

Stay on the weekly Parasite Cleanse Maintenance Program indefinitely, as suggested by Dr. Clark, or at least a minimum of 4 weeks. The initial 18-day cleanse delivers only about 10% of the full benefit of the Parasite Cleanse. The Maintenance Program, taken weekly, will give you a better indication of what this cleanse can do for you.

Take the herbs once per week on an empty stomach, at least 13 minutes before eating. Try to take all three herbs in one sitting. If some capsules get stuck in your esophagus, eat a bite or two of bread.

Trouble Sleeping During the Parasite Cleanse

During the die-off phase microorganisms produce ammonia, and this ammonia gets in the brain and can keep you up at night. We recommend that you order Ornithine when you order your Parasite Cleanse. Ornithine helps your body neutralize the effect of ammonia. How much do you take? Start with 2 capsules, but you may need up to 8 capsules in order to feel the effect. Melatonin is also an excellent sleep aid. Sleep aids should not be used continuously for more than 7 days.

Parasite Cleanse High Dose Program

Do this program every two to three months in place of the Maintenance Program. Do not substitute this High Dose Program for the initial 18-day Parasite Cleanse. For someone ill with flukes the die-off effects are too intense at these dosages. Take for three to five days in a row for three to five weeks. You may take these herbs at different times in the day or all together. Continue to take Ornithine at bedtime as needed. Start with one or two capsules, but you may need up to 8 capsules in order to feel the effect.

Parasite Cleanse for Pets

The dosages are based on a 10 pound (5 kilo) cat or dog. Increase dosages accordingly using this base measurement (double for a 20 pound dog/cat, triple for a 30 pound dog/cat, etc.), but always start with 1 drop/pinch and increase by 1 drop/pinch per day if animal weights more than 10 pounds. Treat cats only twice per week. Treat dogs daily.

Mix herbs directly into food. Do not force your pet to eat the herbs. Go slowly so the pet will learn to eat it, introducing a new herb weekly over four weeks.

Making Parsley Tea
Boil two bunches of fresh parsley. Rinse parsley and boil in ½ quart (½ liter) of water for 3 minutes. Strain and pour into ice trays and freeze. For convenience make each ice cube contain the correct dose of Parsley Tea based on the weight of your pet. Discard the used parsley.

For your convenience, we sell Freeze-Dried Parsley Capsules. You can use pinches of Freeze-Dried Parsley instead of making the Parsley Tea.
