The Varichrome Pro

What makes the Varichrome® Pro so versatile?

Could the variability of the stimulation be more like a video than a still image?

The Varichrome™ Pro selectively emits photons with wavelengths throughout the visible spectrum (430-700nm), a few wavelengths at a time.

With no missing wavelengths.

Its analog controls let the practitioner vary the wavelength and frequency during therapy.

  • 7 Pre-programmed selections:

    • #1-5 span the visible spectrum

    • #6 yellow

    • #7 spans 440-680nm

  • Adjustable rate of wavelength variation in programmed selections: 4 - 26nm/second

  • Manual range: 430-700nm

  • Frequency: continuous to 500Hz

  • Dimensions: L x W x H: 6.6 x 3.5 x 1.8 inches (Control unit w/o knobs)

  • Weight: <2 lbs

  • Charging power pack: 12VDC @ 18Watts,  charging time ~ 4hrs.

  • Operating time: 2hrs @ max intensity (external power pack)

  • Working distance and diameter: 1.5 inches, 1.5 inches


Could a 1-minute video be worth 10,000 words?

5 pre-programmed ranges cover portions of the spectrum found to help the body improve impaired functions.

Like everything in medicine, you have try it to learn if it will "work" for the individual patient.

Varying the wavelength during therapy efficiently improves the likelihood of prompting the body to resume healing.

The practitioner monitors for a physiological response during therapy. Reports of pain relief often arrive later.

How does the therapy work?

The short answer:

The body heals itself; the therapy prompts a restart.

Speculation, of course, the photons stimulate the skin with ever-changing signals and the brain responds.

The process shares similarities with touch and hearing. The brain, nervous system, and skin or ears are "tuned" to simultaneously detect and respond to a myriad of different signals. For example, unexpectedly hearing your name at a football game or intentionally attempting to talk with another person in a crowded room. It's the task of bodily systems to improve communications.


Finally, would the return to normal functioning be noticed if it happened at the right time?

Could the impairments suggest which wavelengths to start therapy?

The impaired functions may suggest which wavelengths to start therapy. Consider that the patient may be experiencing multiple impairments.

Practitioners familiar with physical medicine devices may consider the selections to be like a suite of similar tools. Feedback from the patient may help to quickly find which selection "works" for the impairment. (Dogs and cats just jump off their owner's lap with greater ease.)

Physiological improvements in the impaired function(s) provide early markers for deciding when to stop therapy for the visit.


See examples from the Instant Verification System:

  • Improved range of motion

  • Improved sensation in feet and fingers

  • Ending persistent feelings of coldness in limbs

  • Fresh exudates that may appear during treatment in moist non-healing wounds.


The numbers 1 thru 5 correspond with the pre-programmed selections on the Vari-Chrome Pro.


How might a few photons promote healing?

What might distinguish photons from medications that must remain active to maintain a beneficial effect?

Each photon deposits its quantum of energy into a single molecule then exists no more. This all takes place in less than a trillionth of a second.

The body does the rest. We don't know how that might work.

Bringing attention to an injured site on the skin might prompt the completion of tasks that had been stalled for years. Some patients report that the feeling is like when they find their lost glasses.


Graphic is best seen on a computer.

Critically important, it's the molecule that "selects" which wavelength(s) of photons that it might absorb. A difference in wavelength of 10nm may determine success, or not. That's why the Vari-Chrome Pro's "no missing wavelengths" may contribute to the practitioner's success.

Why vary the wavelength and frequency during therapy?


What might be the purpose of living things "getting used" to their surroundings? Could static inputs be boring?

What if you continuously varied the temperature of your shower water?

Couldn't the detection of the next small change be vital to living things?


Pain specialists call an increasing sensitivity to a varying stimulus "windup" as a quantitative measure of the nervous system functioning.


Is it working?

Everyone wants to know how long it might take to see if the therapy is "working".

In seconds to minutes for some cases that were not expected to ever improve. That puzzled the anesthesiologist and neurologist advisors. They asked for more data from the Instant Verification System.

The responses usually begin during the 1st or 2nd visit. Typically, 2 visits with no response or benefits are enough to suggest trying a different therapy. Inflammation may take a bit longer to observe improvements.
