Frequently Asked Questions

1. What is silver iontophoresis?

Silver iontophoresis utilizes an electric field, just as is generated between the ends of a battery, to move atoms of silver with an electron knocked off so that they have a positive electric charge (‘cations’), through living tissue.

The silver ‘cations’ can be transported either through the skin and deep into the body, or across the skin, depending on how the SIS electrodes are positioned on the body.

Silver iontophoresis can thereby be applied for the treatment of an internal infection, or for the treatment of a skin infection.

Silver iontophoresis is achieved with very small electric currents that are in the ultra low microampere range, which are billionths of an Ampere of electric current, and so cannot be felt.

2. Does silver iontophoresis have the side effects of antibiotics and antiviral drugs?

No. None of the side effects known to be caused by antibiotics and antiviral drugs have been reported from the hundreds of applications of silver iontophoresis for infection and other treatments over a period of more than 7 years at the Electromedicine Clinic, Melbourne, Australia, where the SIS equipment was developed and continues to be used regularly.

Additionally, none of the side effects of antibiotics were reported by the electromedicine pioneer, American orthopedic surgeon Robert O Becker (1923-2008), nor by his research associates during their many hospital applications of silver-nylon cloth electrodes and iontophoresis for infection treatments and tissue healing.

4. Can the SIS equipment be used for the treatment of yeast and fungal infections?

The M200 model can be programmed for the treatment of yeast infections.

It is reasonably possible that the SIS machine M200 model can also be used for the treatment of fungal infections, as there is published data in the medical-scientific literature that silver ions are effective against fungi. This potential application requires further clinical research by our team at this time. If successful, we will publish the M200 model user-programmable Output Current setting for fungal infection treatments [Target: 2017].

5. Can the SIS machines be used for the treatment of parasites?

No, the SIS machines are not appropriate for the treatment of parasitic infections.

The SIS machine M200 model has been designed primarily for the treatment of bacterial and viral infections. The M200 model SIS machine can also treat yeast infections.

6. Can the SIS machines be used to treat cancer?

As a manufacturer of medical equipment, we do not give medical advice, so here is our general reply to this question:

A ‘neoplasm’ is the medical term for what is commonly called a “malignancy” or “cancer”. ‘Neoplasms’ are occurrences that form over time, as a result of many very complex and simultaneous processes.

The SIS machines are not designed nor claimed to be effective when applied alone in the treatment of ‘neoplasms’.

Many ‘neoplasms’ are known to be caused by infections, in addition to many other simultaneous co-factors. These include but are not limited to the more well-known ‘neoplasms’ that can develop in the liver, stomach, and cervix in women. There is gradually accumulating evidence that ‘neoplasms’ in other organs of the body might also be caused by infections, especially by viruses.

In so far as ‘neoplasms’ have infectious agent co-factor causes, then the SIS machines can be applied to treat these infections. However, as explained above, most ‘neoplasms’ have multiple, simultaneous co-factor causes.

We therefore explicitly disclaim that the SIS machines can be applied alone to treat ‘neoplasms’.

If the SIS machines are applied for the treatment of ‘neoplasms’, they should be used as part of a comprehensive treatment program, under the guidance of a Healthcare Professional.

7. Do I need medical expertise to use the SIS equipment?

No, none. One of the major aims of the SIS Machines Project is to supply directly to individuals, anywhere in the world, advanced electromedical equipment, that is fast and simple to apply, and that they can use capably at home, without any medical expertise.

We also give full and ongoing support with the SIS equipment towards correct and optimal application.

8. Have the SIS machines been tested within a hospital environment for the treatment of acute infections?

Yes, with very successful results that resulted in the recovery of the patients. In these cases, within major and regional hospitals in Melbourne, Australia, an SIS machine was used at the insistence of the patients and/or their families when standard treatments with intravenous and oral antibiotics were not giving the necessary results for these patients’ acute or emergency conditions.

The hospital doctors were aware of and included the applications of the SIS machines in their clinical notes.

Additionally, no adverse affects were reported by the hospital doctors or nurses.

9. Do you give support for use of the SIS machines and electrodes?

Yes, we certainly do! We provide full and ongoing support to the original-purchase user of an SIS machine for its correct and optimal application.

And we will always communicate promptly, and with as much help and detail as necessary towards correct and effective use of the SIS equipment.

10. How many times can the SIS electrodes be re-used?

Typically, for a severe or acute infection, with 24/7 continuous use, from clinical experience we recommend replacement of the SIS +ve electrode every 24-48 hours, and replacement of the SIS -ve (return) electrode every 48-72+ hours.

More information

In in vitro testing, with continuous use, each SIS electrode can perform uniformly with a steady rate of silver ion release for approximately 12-60 hours, depending on the individual application. In all cases, after 60 hours, silver ion release can decrease to lower and less effective rates.

Detailed information and instructions for application of the SIS electrodes are given in the SIS machines operating manual, and in the Instructions For Use included in each SIS electrode pack.

11. Are the SIS electrodes self-adhesive?

No, the SIS electrodes are not ‘sticky’. They need to be held onto the body using standard, adhesive medical dressing tape, other types of physiotherapy or medical tapes, bandages or other emergency means.

A 10 meter roll of Fixomull® Transparent dressing tape is included with each SIS machine.

Replacement tape is a generally available item from any chemist or pharmacy, and from our SHOP >

12. Can the SIS equipment be used to sterilize water?

The SIS M200 model has also been designed with small-scale water treatment and purification purposes in mind.

We have not yet conducted an independent laboratory test of water sterilization. We therefore disclaim that we imply or have any data to support or confirm the usefulness of the SIS equipment for these purposes at this time. We intend to conduct the necessary assessment soon [Target: 2017].

13. Can the SIS equipment make ionic (“colloidal”) silver solution?

Yes, very easily with the M200 model. The silver stimulation surface of the SIS electrodes are 99+% pure silver (Ag). When two SIS electrodes (anode and cathode) are immersed into a container of distilled or purified water, an ionic/colloidal solution will be produced.

Alternatively, the SIS machine harness (connecting wire) can be easily connected to widely available pure silver electrodes made specifically for “colloidal silver” production, using the set of Alligator Clip Harness Adaptors supplied with each SIS machine M200 model.

14. I have a colloidal silver generator, are the SIS machines the same and do they do the same thing?

No, they are entirely different. Please read the information below or click on the link to read how the SIS machines work for infection treatments.


More information

“Colloidal silver” (ionic silver solution), though certainly of use for surface infections, has major limitations for the treatment of internal infections. The human body is often imagined as something like an homogeneous bathtub of water: If you drop a substance into it, it will spread out and automatically go everywhere. In anatomical and physiological reality, the body is extremely compartmentalized and barriered, at every order of anatomical scaledown to the sub-cellular level. Silver ions do not automatically travel inside the body to where it is wished that they go.

Furthermore, for orally ingested silver ion solution or spray there are a million, million molecular binding sites available for them, starting high up in the gastrointestinal (GI) tract itself. For example and illustration, the chances of getting any kind of (constant) therapeutically viable dose of silver ions to an acute and severe kidney infection are probably very small. After taking the colloidal silver orally, the silver ions must get through the stomachwhere they can bind to the stomach’s hydrochloric acid, then go through at least part of GI tract; if they are not directly absorbed through the walls of the intestines into the local blood vessels, then they must go up through the portal venous system to and through the liver, then to the heart, in and out of the lungs where blood is oxygenated, then back into the systemic bloodstream, around the body in any case, then through the renal (kidney supplying) arteries, and eventually to and into the inner compartments of the infected kidney.

Additionally, there is the generally under-considered issue when taking any medication, of localized, elevated ‘thromboxanes’—fatty substances that are part of inflammatory processes and that cause blood clotting and blood vessel restriction. ‘Thromboxanes’ are often elevated in infected areas of the body due to the activities of the infecting microorganism(s), and other coincidental tissue ‘microenvironmental’ problems. In almost all such instances, these occurrences cannot be felt or distinguished subjectively. The presence of these ‘thromboxanes’ results in a reduced amount of medicine, or no medicine at all (either pharmaceutical or not), reaching the infected area of the body via the bloodstream.

A technical journal article that discusses in depth the role of ‘thrombaxanes’ during inflammatory processes is available here.

In contrast, the SIS machinesutilizing silver iontophoresisdo not depend on blood flow to reach the target internal infection. The constant direct current (DC) silver ion delivery of the SIS machines, operating on the basic physics of electric voltages and electric currents, delivers a constant DC of silver ions via the shortest possible route, directly to the infected area.

15. Are the SIS machines like “zappers”, or “bio-resonance” devices?

No, these are all electromagnetic frequency generating devices.

The SIS machines models M200 and W200 are direct current (DC) silver iontophoresis devices. They have no operational frequency, as they are DC devices. They have no functional similarity to any frequency generating device.

There are no other silver iontophoresis devices available in the world, as far as we know, which is why we had to invent them.

Please read HOW IT WORKS >

16. If I have a microcurrent stimulator can I use it with the SIS silver-nylon electrodes?


The SIS machines should not be compared to commonly available, portable microcurrent stimulators either electronically or therapeutically.

More information

The SIS machines are direct current (DC) devices that are necessary for silver iontophoresis. Most currently available microcurrent stimulators are not DC devices—they are pulsed waveform, frequency generating devices.

Additionally, for silver iontophoresis using silver-nylon electrodes as the +ve electro-chemical anode for the release of silver cations (Ag+s), very stable and high accuracy ultra-low microcurrent is required. The SIS machines have a confirmed, stable constant Output Current accuracy of ±100 nanoamperes (nA) between 1-20 microamperes (uA). The Output Current accuracy and stability of the SIS machines is further regulated by the on-board, full feedback proportional-integral-derivative (PID) real-time circuit calibration and control system. This Output Current stability has been tested and verified across an extreme temperature range in an environmentally controlled chamber.

No currently available microcurrent or other electro-stimulator that we are aware of has these capabilities.
