Dr. Clark’s passion for the radio brought her to understand that not only the human body broadcasts electrically just like a radio station, over a wide band of frequencies and at very low wattage’s, but that other organisms transmit electrically as well. This lead to her invention of the SYNCROMETER, an audio oscillator circuit device that tunes into and detects the resonance in all things in much the same way a radio tuner locates a specific station. Even though not a scientifically approved device, without the Syncrometer, Dr. Clark would not have been able to carry out all her findings that she penned in 8 books.

The SYNCROMETER is a diagnostic device. It is not used for therapy. It finds things in and out of the body. It is an audio oscillator circuit that detects resonance in much the same way a radio does. In your radio a distant frequency produced in a studio is matched to a frequency you produce in your set. The Syncrometer matches a frequency produced in your body with one you place on a capacitor plate.

It can scan for anything in the body – be it an object, an organ, a chemical or virus because everything has a characteristic frequency or set of frequencies. The Syncrometer detects the presence of parasites, bacteria, viruses, fungus, toxins and more. The Syncrometer is more accurate and versatile than the best existing testing methods. However at this point it only yields positive or negative results, it does not quantify. The chance of a false positive or a false negative is about 5%, which can be lessened by test repetition.

Nonetheless testing with a Syncrometre does not equal a medical diagnosis. Dr. Clark‘s research with the Syncrometer is based on Biofeedback. Biofeedback research is not considered scientific by US Government or medical authorities. Measurements made by the Syncrometer have no relation to orthodox western medicine and the Syncrometer provides no method of obtaining quantitative measurements of any substance contained in a tested sample. Only an approved and legally recognized laboratory may offer this information. In order to use the Syncrometer effectively, one must practice a lot.

The best Syncrometer- testers are the Clark therapists that test daily with the Syncrometer.It is very easy to have a Syncrometer test done even if you live at distance. You can simply send in a sample of your saliva to a syncrometer tester. The sample of your saliva is matched with the frequencies of a specific pathogen. You can also test the saliva of your pet, or you can have your water, house dust or body-care products tested. There is no need for you to be present in person.


For years Dr. Clark used a frequency generator to “zap” one pathogen after another. This was very time-consuming. Zapping means electrocuting pathogens. In 1994 her son built a hand held, battery operated, and accurate frequency generator. The purpose was to kill the intestinal fluke. To her surprise she noticed that this battery-operated zapper killed all pathogens without having to set in a specific frequency.

This was a GRAND invention!

Dr. Clark mentioned in her books that the zapper kills small organisms but also re-activates our immune-system. With these two grand inventions, the Syncrometer and the Zapper, Dr. Clark could now test with the Syncrometer for the presence of the pathogen and the organ in which it was found, and then use the Zapper to “electrocute” the pathogen. Dr. Clark came up with other inventions in order to remove body obstacles. In the case of Herba Farmacy, we were privileged to work side by side with Dr Clark to create our own unique Zapper that would be affordable to all South Africans. Hence the difference in Dr Hulda Clark’s Zapper and ours.

Dr Clark helped us build this unique Zapper to her strict protocols and we have been producing the same one for over 22 years now. The best and easiest way to compare the Clark Zapper and ours is to understand three main areas.

  1. The Price difference
  2. Availability
  3. Operations

Dr Clark’s Zappers are available from overseas at a huge cost to import and pay duties on.
Herba Farmacy determined that not everyone has the ability to pay for the Clark Zapper due its cost. This was one of the primary reasons we collaborated with Dr Clark to produce a cheaper, but just as effective , model that could be sourced locally at a reasonable price.

The availability of the Zappers was also a issue due to the fact that importing them would not only cost a huge sum of money but the time delay was in some cases rather long to getting the Zapper released from customs. When we look at the importance of the Zapper and that in many cases the original starting point is beginning with Zapping, these huge time delays often to the disadvantage of the clients health was not acceptable.

We also determined that clients needed a instrument that was easy to operate and manage safely. The Dr Clark Zappers need a fair amount of training to use effectively and safely. Not everyone had the time due to health conditions or ability to undergo training to use the Clark Zapper effectively.

Thus The Herba Farmacy Zapper was created in the fashion of literally turning the instrument on and using it. Simple, Easy and Fast….
