I first heard of using the parasite zapper to cure diseases from Wayne Green of magazine publishing fame. In an editorial, he expanded on the virtues of the Zapper and its ability to cure diseases. For a number of years, I heard little of the Hulda Clark Zapper until one spring, a number of the people in the office where I worked started coming down with the flu. Everyone was missing 3 to 5 days and still not doing well. This continued for a few weeks, with the cycle repeating itself. The same people, including myself were getting sick over and over again. One person in the office appeared not to be catching the flu. Then one afternoon, he suddenly came down with the bug, leaving to go home. He returned the next day, feeling fine!

When I asked him his secret, he handed me a little hand built Zapper, claiming that it helped him stay healthy. Immediately impressed, I decided to try zapping and was amazed with the results. A few days later, I started coming down with the same flu. I tried the zapper and within a few hours, I was back on my feet and feeling better than I had in months. It has been 3 years since the flu or a cold has put me in the bed sick! This is amazing to me as I normally came down with a cold or flu several times a year. While I still have sinus problems and occasional allergies, they are much less severe than in the past.

Using the Zapper, I removed the pain of a tooth infection in a day, broke colds and the flu, and have felt healthier since starting to use it. I also noticed later that my problem with IBS had been helped by zapping.

While use of the Zapper was first suggested by Dr. Hulda Clark in her book The Cure for All Disease, Dr. Clark does not manufacture or sell zappers to the public. She and her son do continue to publish information about the zapper and to provide technical updates. Her son will also certify zapper products that meet or exceed their standards.

While Dr Clark has been persecuted in the past about her claims ( see Quackwatch ), She has been vindicated by several recent research projects including published papers. Some of these papers show that in fact, liver flukes can and do cause some cancers. Clinical studies are coming in that show that the zapper does work. This is a link to Dr. Clarks public statment

Not being a doctor, I can not prescribe the Zapper to you, nor can I guarantee any results, but I do believe in its effectiveness in reducing the effects of illness. We have users call almost every day telling us about the parasites that the zapper has killed. There are many testimonials on the Zapper and the curing of illness such as multiple sclerosis, cancers, colitis, and even arthritis by zapping. I have heard from 2 users who use the zapper to fight the long term problems that sometimes follow a brown recluse spider bite. My wife now uses the Zapper to reduce her arthritis problems.

How does the Zapper work? The study of Radionics suggests that all organisms are susceptible to certain frequencies of electromagnetic energy. A vibration of 5 Hz will kill chickens due to resonance of their skull cavity. Many bacteria and viruses are affected by frequencies of 300 kHz to 450 kHz. Protozoa, roundworms and flatworms are affected by frequencies between 350 kHz and 500 kHz. Molds appear to be affected by lower frequencies of around 80 kHz to 220 kHz. Individual species respond to specific frequencies within these ranges. Some have 1 main frequency while other have several resonant frequencies.

While there are many versions of Zappers available, I have not found any that are more effective than others provided that both 30 kHz and 2.5 kHz frequencies are available. Why both frequencies? They both have different frequency spectra.

All Zappers produce a square wave output. This square wave is composed of all odd harmonics of the main frequency. These harmonics effectively stretch up into the megahertz range, which is where parasites are affected. The 30 kHz frequency produces a range of frequencies that are 30 kHz apart. The 2.5 kHz range produces harmonics that are 2.5 kHz apart. Because each harmonic is weaker than the previous, The lower base frequency produces much smaller amplitudes than the 30 kHz units at any given frequency.

According to information available from the study of "Radionics", bacteria such as anthrax, chlamydia, shigella, and e. choli have spectral responses between 392 and 398 kHz. This would be near the 13th harmonic of 30 kHz, and near the 157th and 159th harmonic of 2.5 kHz. The 13th harmonic has an amplitude of 1/13th of the main frequency and the 157th harmonic has an amplitude of 1/157th of the main frequency. The tradeoff of amplitude vs. closeness to the needed frequency has to be weighed in considering desired results.

Some believed that the higher the frequency, the greater the skin effect. That is higher frequencies tend to travel along the surfaces of the body and lower frequencies tend to penetrate better. For this reason, many believe that the lower frequencies are more effective against intestinal parasites, urinary infections, and other infections that tend to occur in the various body cavities.

It might just be that the 30kHz frequency does not produce harmonics close enough to the parasite's frequency since its harmonics are 30 kHz apart while the lower frequency has harmonics that are only 2.5 kHz apart. Regardless of the reason, many users feel that the 2.5 kHz frequency is more effective in alleviating certain problems.

There are also several new technologies, most of them are not much more effective than the original zapper. We have tried spread spectrum with disappointment, several test units were sent to clinics for evaluation. The general response is that the standard zapper is better. This may be because the time spent on any one frequency is not long enough to have a positive effect. The units that require modules (smart keys) for each parasite or illness can cost thousands of dollars for full effects. The little finger zappers or touch zappers that you only touch with your fingers can not provide as strong of an effect at distant parts of the body.

Wrist Straps used by many Zappers have limited effectiveness. These straps and cords while being convenient, are made for antistatic applications and include a high resistance (1 megohm). This steals most of the voltage that the Zapper puts out and makes it much less effective, especially those with coiled cords. Even the better units which do not have resistors provide a very small contact area which reduces the signal and may cause wrist burns.

Augmentation copper foot pads provide a significant improvement in results. These provide a more complete and uniform signal across the whole body. The other type of foot pad only substitutes for the copper hand holds and is basically for convenience. Augmentation foot pads are used along with the copper hand holds to provide extra effectiveness.

Questions and answers:

The hardest question that any user might ask is:

Does it work?

I have tested its functionality "in vitro" and it does work. It kills or prevents growth in protozoa and bacteria. Identical prepared solutions of growth media we placed side by side, with one being zapped 4 times a day and the other not being zapped. The zapped media remained clear while the other control media became cloudy with bacteria and protozoa. If you have any doubts, try it yourself. In a trial test, Dr. Robert Thiel found that 97 % of participants reported improvement within 45 days (ANMA Monitor 2(4):5-9.1998). Additionally, we observed protozoa under the microscope while they were being zapped. When the zapper was turned on, they immediately moved away from the positive terminal and toward the neutral. After a while, the protozoa began to swell, loosing their coordination and their ability to move about. Soon afterward, internal organelles within the protozoa became disorganized and eventually the outer cell membrane ruptured causing the protozoa to explode dumping its cellular contents into the fluid around it. All species of protozoa tested this way followed the same path of destruction. You can see an actual video of this. Video: ParaZapper killing Protoza.

In a recent clinical trial at a major US university, ParaZapperMFC ™ was tested with a group of 25+ individuals and was found to stop the progression of cold and flu symptoms when used at the onset of symptoms.

Ok, so it works, how is it used?

The Zapper is easy to use. It is provided with two hand held "paddles" one of which is held in each hand while the Zapper is running. The Power switch is turned on and zapping continues for 7 minutes or longer in some cases. The unit is then turned off for 20 to 30 minutes. The process is then repeated for another 7 minutes. The cycle is then repeated a third time. A complete session requires zapping 3 times over a period of 1-1/2 to 2 hours. It is recommended that the process be repeated once daily for several weeks for best results. Afterward, you can zap once or twice a week to prevent reinfection.

The LED on my zapper comes on, can I be sure it is working?

Yes, This is easy. Find an AM radio (FM will not work for this) and turn it on. With the zapper turned on, turn the tuning dial until a whine or squeal is heard. Turn the Zapper off and on several times. If the whine stops and starts with the off and on, then the zapper is working. Note: the LED is powered by the zapper outputs so if the LED is on, then the zapper is working.

Is the Zapper safe to use?

Yes, however, you should not use any zapper or similar product if you are wearing a pacemaker of if you are pregnant. There is the possibility of small amounts of metals leaching from metal prosthetic implants. Do not over use or abuse the zapper. Do not use while in water. Do not connect to a battery charger or a wall transformer as there is a high risk of electrocution. Always seek the advice of a medical professional with regards to any health issue. Zappers of various designs have been used over 10 years with no dangerous side effects. Some users report occasional burns on the wrist from wrist straps. For this reason, the wrist straps are not recommended.

Are there any side effects?

Yes, extensive zapping can kill beneficial bacteria in the intestine causing intestinal irregularity. Intestinal regularity can be restored by eating yogurt and drinking buttermilk. Some users (less than 0.5%) have reported problems with skin rash on the hands or arms. Some others who use wrist straps have reported skin burns.

Is one brand of zapper better than another?

Some zappers use less power from the battery thereby making the battery last longer. Some cycle on and off automatically ( actually not recommended ). Otherwise, most zappers perform the same function, that is outputting a 9 volt square wave at some frequency. A lower frequency of 2.5 kilohertz is probably better as discussed above.

What happens to the parasites that are killed?

The parasites that are killed may actually explode as shown in the video mentioned above. Others may be damaged bad enough to decay. The bodies defense mechanisms have to clean up and remove the killed organisms. For this reason, you may feel fatigued throughout the day following zapping. Drink plenty of fluids, replenish your intestinal inhabitants, rest, and take it easy for the day.

Does it matter which paddle goes in which hand?

No, not really, we do recommend that you swap paddles each time that you zap. Red lead in the right hand one time, red lead in the left hand the next time.

Do I have to hold the paddles in my hands?

No, some people place them under their feet, others have sat on them. This should be acceptable as long as the paddles do not touch.

Should I feel anything while zapping?

While some individuals may feel a slight tingling, it is not necessary and certainly not a problem.

Can I get electrocuted?

No, not from the ParaZapper as the current output of the ParaZapper is limited by built in resistance. Also, the output voltage is less than 9 volts which is safe in itself. Never connect a zapper to a battery charger or other form of power from an AC outlet.


Since many allergies are the result of or are aggravated by certain parasites, relief can be obtained by removing these parasites.

IBS and colitis?

As Colitis and IBS (Irritable Bowel Syndrome) are frequently the result of certain parasites in the intestine, relief can be obtained by removing these parasites. The zapper can be very effective in removing these parasites without dangerous chemicals.

Note: The original zapper is not as effective at relieving IBS as it does not have the 2500 Hz frequency.

Cleaning the zapper?

The case may be cleaned with a damp cloth and mild soap. Do Not soak or allow any water to get inside!

The paddles may be cleaned and shined with steel wool.

Recommended: Many users also wrap the copper tubes with a damp paper towel (using a solution of sea salt ) to keep the copper off of their skin. This also reduces resistance and applies a more powerful signal to you.


Do not use any Zapper type product if you are wearing a pacemaker or if you are pregnant.

How Frequently should I Zap?

The frequency and amount of zapping depends on the individual, his / her condition, and the type and extent of illness being treated. Starting out, most users zap 1 or 2 sessions a day. This is normal for the first 3 to 5 days and up to 45 days. Afterward, users may zap from once a day to a couple of times per week. Once parasites have been reduced or eliminated, the need to zap is reduced.

How Long should each zapping session last?

Normal zapping is for 7 minutes with a 20 minute resting stage in between. This is repeated 3 times for each session. In extreme cases, some individuals choose to zap continuously for a full hour. There is probably no harm in this, but it is likely to reduce your natural intestinal inhabitants. It is important to drink buttermilk and/or eat yogurt to replenish this.

Can I eat or drink while zapping?

Always wash your hands after handling copper ( or any other metals ) before eating. Except for replenishing the normal intestinal inhabitants ( see Replenishment below ), it is recommended to eat only fresh fruits and vegetables for 2 hours before and 6 hours after zapping. This is not imperative, but it allows normal intestinal inhabitants to be replaced. It is also very important to drink lots of water before, in between, and after zapping sessions. It is needed to remove toxins and waste byproducts.

Why should I use salt water and and paper towels or sponge pads?

The saline solution reduces the resistance of the skin surface and allows a stronger signal to reach your parasites. The paper towels help keep the copper off of your skin and to hold moisture. They are also cheap and disposable. Do not use the saline sold for contact lens users, it is too weak.

How can I make the saline solution?

Sea salt is preferred and is available from most grocers. Mix one teaspoonful with about 2 ounces of warm water. Soak a couple of thin sections of natural sponge or paper towels in this solution. Wrap around the copper paddles or place under the metal of the wristbands. Included with your ParaZapper is a small package of sea salt and two half paper towels to try this.

How can I get the most out of my Zapper?

1) Use your zapper regularly after initial parasite treatment. A couple of times a week is usually enough. This should prevent occurance of problems.
2) Use sea salt ( table salt will work ) to increase effectiveness. This will reduce the effect of skin resistance.
3) Always drink plenty of fluids before, during, and after zapping.
4) Get plenty of rest after zapping. Rest gives your body time to remove unwanted byproducts and to clean itself.
5) Switch polarity each zapping session. Use the red wire to the left arm on one session, and to the right arm on the next session. Parasites nearest the green lead probably get the least effect from zapping. Also, this tends to reduce any ionic migration effect that may be present.
6) Using both frequencies will reach more parasites.
7) If you need to eat, eat only fresh fruit and raw vegetables for 2 hour before and 6 hours after zapping.
8) It is recommended to eat some yogurt or drink buttermilk soon after zapping.
9) Many users report even better results with augmentation copper foot pads.

Replenishment of intestinal inhabitants

The intestine normally contains a variety of bacteria and protozoa that are actually beneficial in helping to digest food. It is important to replace these after zapping. To do this after a complete zapping session, you may take probiotic tablets, acidophilus tablets, eat a couple spoonsfull of yogurt, drink a few ounces of buttermilk, or drink a glass of regular milk ( not quite as good ). Do this after each zapping session.

What should I expect?

After first zapping many individuals will either go through a phase of tiredness. Others experience slight diarrhea while some experience both.
These conditions should not last long ( a day or so ).
Parasites that have died in the body leave debris that must be removed and the body may use a lot of energy doing this. Drink lots of water and get plenty of rest.
Also, the loss of intestinal inhabitants can cause diarrhea. Take some Acidophillus tablets, drink buttermilk or eat yogurt.

Usual Steps to Zapping

1) Install battery if it is not already in.
2) Prepare your salt water solution. About a teaspoon in a cup of warm water.
3) Connect copper tubes (paddles) or wrist straps to your ParaZapper.
4) Place paper towels (or cloth) which has been lightly wetted with salt solution around paddles or under metal plate of wrist strap.
5) If using wrist straps, put them on, one on each wrist.
6) Select your preferred zapping frequency 30000 Hz with button in, 2500 Hz with button out.
7) Turn on power to your ParaZapper.
8) If using copper tubes (paddles) pick 1 up in each hand and grasp firmly. There is no need to clench though.
9) Normally, continue for 7 minutes.
10) Turn your ParaZapper off. Set down paddles or remove wrist straps.
11) Wait 20 minutes.
12) Swapping the red and green leads, repeat steps 3 through 11 above twice more for a total of 3 zappings.

It is strongly recommended that you complete all three zappings for a full session.
Failure to do so can make you very sick

Using Saline Solution for Zapping

A survey was sent to users after a couple of months. The important information that we have received is that those who use the saline solution report better results. This would be true for any and all zappers.
