F.A.Qs (Frequently asked questions)



1 – I’m allergic to nuts. Can I use the Black walnut tincture anyways?
Being allergic to nuts, doesn’t necessarily mean you are allergic to the HULLS of the black walnut.
You can have this checked with a RAST test or alternative methods of allergy testing.
If allergic to the black walnut tincture, experiment with other combinations such as e wormwood, cloves and apricot seeds

2 – How long does the black walnut tincture last?
It is only the green hull that has the parasite-killing power. It loses this power in contact with the air. It is important to pour only what is needed then reclose the bottle immediately. If possible store in freezer after opening or at least in fridge.

3 – Are the premixes available just as potent as the separate ingredients?
Dr. Clark states on page 79 of the “Prevention of all Cancers” book that these herbs must be taken together as a single treatment but not premixed because they interact with each other to destroy their potency.

4 – What do I do if I don’t feel good while taking the parasite cleanse.?
Reduce dosage to the point where your body tolerates it.

5 – Can I do the cleanses while pregnant or breastfeeding?
This would be up to your own judgement as cleansing and zapping moves toxins in the body. If possible it would be best to wait until you do not breastfeed anymore.


1 – Do I continue with the kidney cleanse even though it causes me diarrhea?
Reduce dosage to a point where your body is comfortable with it.

2 – What if I am allergic to goldenrod?
Take the kidney cleanse without the goldenrod


1 – Is it necessary to ozonate the oil?
It would be best as the ozonated oil kills off bacteria, parasites  and also viruses stuck on liver stones and in the bile

2 – After the liver flush  why do I have intestinal disorders?
An extra flow of bile brings an extra flow of bacteria. Ozonate the olive oil to kill these or do a hydro colon therapy after the liver flush.

3 – Is it possible for a stone to get stuck?
A small risk does remain that a stone can get stuck, but this has happened rarely in the past. It is important to follow the liver cleanse instructions carefully starting with a parasite cleanse followed by the kidney cleanse, before doing the liver flush -- this way more stones will be released and the organs will be in better-working conditions.


1 – What do I do if I don’t feel good on the cleanse?
Reduce dosage to a point where your body feels comfortable with it

2 – How do I know if I am allergic to Lugol’s iodine?
Persons who are allergic to iodine should not use Lugol’s. Such allergies develop after a large dose of it has been injected as part of a kidney or thyroid scan. The doctor will warn you about it afterwards. Allergies to shell fish are often an indication of an allergy to iodine. If you are unsure, you could call your doctor’s office to check your record (Prevention book page 519)


1 – Is it necessary to ozonate the olive oil?
Yes, as ozonated oil has penetrating effect. Ascaris are known to release 200’000 eggs a day. The penetrating effect of the ozonated oil will kill the eggs first so that the ascaris can decompose


1 - Is the 21-day program the same as the 3-week program?
No, the protocol for the 21 day program taken from the book “The Cure for all Advanced Cancers” rectifies the cellular deficiency
The 3-week program has been taken from the book: “The Prevention of all Cancers”  and eliminates also the issues of how a cancer starts.
There are less supplements to take in the 3-week program. These are replaced by homeography and plate-zapping, two new techniques.



1 – How long do I zap?
Zapping once a day until one feels better is a common routine for many persons. If one if very ill
Zapping all day, continuously, for a month or more has often brought significant improvement.

2 – What is the difference between the zapper and the frequency generator?
The zapper effect is frequency independent. It is not necessary to use a specific frequency as the square wave of the zapper hits all frequencies. The frequency generator produces specific frequencies.

3 – What is the difference between a square wave and sine wave?
Square waves are the assembly of many sine wave frequencies. In this manner, it is not necessary to focus on a single or on a set of sine wave frequencies.
You could illustrate it this way: working with square wave is like using a shotgun, it shoots  a broad pattern. Using Sine waves from a frequency generator is more like shooting with a rifle, you work with specific frequencies. This is a more targeted way of zapping.

4 – Is square wave or sine wave zapping better?
The combination or alternation of the two is best. However, it is important to have researched the specific target when sine wave zapping is applied so that frequency selected will be effective

5 – What is the meaning of positive offset?
The wave does not go below zero volt. See picture below


6 – Why must the square wave be always positive offset?
If the varying voltage becomes NEGATIVE, even momentarily, it supports and maintains the lives of the pathogens (page 83 - prevention book)

7 – Why must the zapper be battery-operated?
It is a lot safer on humans. A battery does not emit any frequencies, just clean DC current

8 – Zapping gave me a skin rash. What can I do?
Zapping gives skin irritation to some people. Do not zap on the irritated location. Change location or use carbon handles, slippers or gel pads. Also make sure that the skin at the point of contact is clean.

9 -  Why is it important to use 30000 Hz for zapping?
According to research of Dr. Clark when a high frequency ac voltage was applied to a human, using hand electrodes, and the current flow measured, it could be seen that the higher the frequency, the greater the current. At about 30,000 cycles per second the current begins to decline, showing the resistance is increasing. Persons with an inflammation in the body can often “feel” the zapper at that location, suggesting it is a path of low resistance, too, for the 30 KHz zapper current. Inflamed areas are negatively charged regions. Negative charges would be pulled toward the positive electrode of the zapper in 30,000 little jerks per second. Therefore a frequency of about 30 KHz (30,000 cycles per second) was chosen for the zapper, since it maximizes the current with regular zapping.  But other frequencies may prove to have special value as research progresses.

10 – What is the difference between regular zapping  and plate-zapping?
There are two types of  regular zapping:
• standard zapping which is 7 min zapping/ 20 min pause/7 min zapping/ 20 min pause/7 min zapping  
• duration zapping: 1 hour non stop

This type of zapping passes mainly through our liquids: vascular and lymphatic system.

Plate-zapping instead, is a specific targeted way of zapping. You work with plates, but you also need the regular zapper to attach the plates to . Whichever organ you put on the plate gets cleaned out of its parasites, bacteria, viruses, toxins , etc. This type of zapping is more time-consuming and complicated but very effective. Plate-zapping overcomes insulator obstacles.
See here:

11 – Is zapping sufficient to remove a health condition?
Zapping is part of the protocol. It must be done together with the cleanses and clean-ups

12 – What does zapping do?
A positive electrical force that pulses up and down not only appears to kill tiny invaders, it also seems to energize your white blood cells to go on an all-out attack on your enemies: your parasites, your toxins, your bacteria. (Prevention book page 83)

13 – If zapping kills parasites, why does one need to take the parasite cleanse?
The zapper current passes mainly through our liquids. It does not enter well in some of our internal organs.

14 - Our intestines harbour many bacteria, the so called “good” and “bad” bacteria, is there not a risk of killing the “good” bacteria together with the “bad” bacteria when we zap?
Although the center of the bowel contents is often unaffected by electric current, sometimes it is nearly all sterilized by zapping. There is no way of distinguishing between “good” and “bad” bacteria. However even good bacteria are bad if they come through the intestinal wall, so zapping targets mostly “bad”.  bacteria.  The good news is that perfect bowel habits often result in a few days. Evidently the good bacteria are benefited by killing the invasive ones. (Cure of all Diseases book)
15 - Is zapping harmful?
I have seen no effects on blood pressure, mental alertness, or body temperature. It has never produced pain, although it has often stopped pain instantly. (Prevention of all Cancers)

16 – Which zapper should I buy?
There are many zapper on the market.  Dr. Clark mentions that many variations in zapping technique have been discovered since the first one found around 1990. The original technique  showed that very small animals like our parasites, could be killed with a very small voltage. But only IF the voltage is 100% Positive offset, and only IF the voltage is varied up and down repeatedly. If the varying voltage becomes NEGATIVE, even momentarily, it supports and maintains their lives! (page 83 - prevention book)
In earlier books a circuit was described that produced a totally Positive electrical field at all times, called "positive offset". But many zappers were built with small substitutions when the exact components were not available. This often brought the resulting electrical field too close to negative so that brief excursions into the Negative field were inevitable."
Therefore it is important when buying a zapper that it is 100% positive offset at all times, even better if 0.25v, square wave.
Prices vary, it all depends on what one wants and  how much he wants to spend.

17 – When is the best time to zap or plate-zap?
Zapping or plate-zapping should be done during the day ONLY as it give a north polarization. Healthy people have a north polarization during the day and south at night.  Read more on polarization here:

18 – Can I zap if I have a metal prothesis in my body?
If the metal prothesis is on the upper part of the body, simply zap on the bottom part of the body and viceversa.


1 - Is the syncrometer used for zapping?
No, the syncrometer is an audio circuit that can test for anything in and out of the body.

2 – Does the syncrometer test on its own or does it need an outside tester?
The syncrometer needs a tester and one needs test samples.


1 - How long does ozonation last?
Ozonated oil has one shelf-day, 4 to 5 days in the fridge and about 1 month in the freezer. It is best however  to make it fresh

2 – How long does it take to ozonate food, oil and water?
It takes about 5 minutes to ozonate water, 30 minutes for oil and from 7 to 20 minutes to ozonate food. Read more about this here:


1 – Can one zap food with the zapper?
It should be possible but it is best to use the food zappicator

2 – What does the food zappicator do?
PCBs, asbestos, benzene and other toxins are destroyed
It does not destroy most vitamins or change food. It oxidizes some minerals.
It destroys:

  • Parasite eggs and stages
  • Bacteria and viruses
  • Fungus
  • Chlorogenic acid 
  • Phloridizin
  • D-penylalanine 
  • Prions
  • D-mannitol  
  • Phenol
  • Gallic acid  
  • Apiol

It gives a north polarization to food and water
Read more about the food zappicator here:


1 - What dental materials are recommended?
Refer to Dr. Clark most recent book: “The Cure and Prevention of all Cancers” under Sources – Dental materials


1 - Does the tooth zappicator replace dentalwork?
No, it doesn’t replace dentalwrok. It removes  lanthanides, other metals, solvents, plastic remnants and bacteria  and hardens plastic so that it doesn’t seep.

2 - Can one use the tooth zappicator on teeth containing metal

Read more here:


1 - What is Homeography?
Frequency patterns are incorporated into water.
You can use homeography as organ therapy giving sick and old organs their correct frequency back.
You can use homeography to take harmful things out of a specific organ as for example heavy metals out of left kidney
You can use homeography to put important things into the body
Read more here:

2 – When should homeographic drops be taken?
They should be taken during the day only as the homeographic drops give a north polarization: Read more here:
