While you have probably heard of "colloidal silver," did you know it is a centuries old remedy? Silver was standard treatment for a long list of ailments dating back to Egypt. Ancient Romans recognized silver vessels as having the ability to prevent diseases arising from food or drink stored in them. Before the invention of the icebox in America, it was common practice to place a silver dollar in the bottom of the milk container to keep it fresh. The table below is a partial listing of illness or conditions which have been successfully treated with silver.

People used to ingest small particles of silver with every meal when they dined from silver plates and drank from silver goblets. However, when modern medicine began implementing antibiotics, silver was gradually replaced.

Additional incentives to promote sulfa drugs were purely economic. Prior to 1938, the cost of silver was $100.00 an ounce. In today's market that would translate to $1,000.00 per ounce. Second, drug companies could not patent silver, but they could patent sulfa drugs These two factors greatly influenced the decision to promote prescribed antibiotics.

While antibiotics certainly have their niche in healing, but both improper and over usage have "improved" the stains of bacteria making them more drug-resistant. The pendulum is now shifting again, not to replace antibiotics, but to again embrace silver's healing qualities.

In order to accomplish this, one doesn't need to sell the family car and purchase solid silver dinnerware. Today you can acquire colloidal silver via three different means:

  • purchase the product bottled and ready to use
  • purchase a colloidal silver generator and make your own colloids
  • purchase the raw materials and make both your own generator and colloidal silver


For those who would rather purchase it "ready-made", check your area health food stores or order it through the Internet. There is wide variance in cost ranging from $4.25 to $10. per ounce so it pays to shop around. Among the many products names colloidal silver is marketed under are Silverkaire, Silver Ice, UltraClear, WaterOZ and True Liquid Silver. There are many more of these products from scores of Multi-Level Marketing companies simply labeled Colloidal Silver under their private label.


With the introduction of the CS-300 and Quik Silver 47, colloidal silver generators designed by Peter A. Lindemann, and Mark Metcalf's Flower Power Generator marketed by Silver Protects, people can easily make colloidal silver at home. Lindemann's product sells in the U.S. for roughly US$99 and US$149, respectively. The CS-300 and Flower Power Generator are similar units by the Quik Silver 47 uses only one 9 volt battery. The price includes two brown bottles for product storage as well as a spray bottle. Metcalf's product sells for US$79. For an in-depth look at these units, check out their information.


For those with a little bit of skill and about 30 minutes free time, Mark Metcalf shares how to make your own colloidal silver generator. See the Making Your Own Colloidal Silver below by Gail Wilts. By her own admission, she has become quite proficient at making colloidal silver and kindly forwarded her instructions. They closely resemble those put forth by Mark Metcalf.


Materials Needed to Make the Generator

  • 3 - 9V batteries (type MN1604 regular alkaline transistor radio batteries)
  • 3 battery snap-on lead connectors
  • 2 insulated alligator clips
  • 1 "grain-of-wheat" 24V 40mA sub-miniature incandescent bulb
  • 1 foot (30.5cm) of 3/32" heat-shrink insulation tubing
  • 10" (25.4cm) pure silver wire, 14 gauge is best (use .999 pure silver, not sterling silver which is only .925 pure) *
  • 1 foot (30.5cm) 2-conductor stranded insulated wire for clip-leads

Total cost is around US$20.

* Using non-pure silver containing nickel can be toxic. Use only .999 pure silver. Silver dollars are not OK to use because they contain metals other than silver. Generally they are 90% silver, 10% copper. The easiest way to obtain this 99.9% PURE silver wire is to purchase it from a jeweler or silversmith. .999 Fine Silver Wire (99.9% pure silver) generally runs $10.95 per troy oz (ozt).


To assemble your generator, solder the three snap-on clips in series, the red to black. The three batteries will produce 27 volts. Next, connect the incandescent lamp in series with either the positive or negative output lead. Solder the red insulated alligator clip to the positive (anode) and the black insulated clip to the negative (cathode) 2-conductor lead wire. Heat shrink insulation over the soldered areas with a blow dryer.

Cut the silver wire into 2 - 5" (12.7cm) lengths. Bend the top ends of the silver wires so they can clip onto the edge of a glass. Plastic may also be used but not metal. (Refer to photo above for proper positioning.)

Making Colloidal Silver in Five Simple Steps

1) Immerse the pure silver wires, attached to the alligator clips, in DISTILLED (not filtered or purified) water** mixed with sea salt if the colloidal silver is to be ingested. (For house- hold use, tap water may be used.) Make sure 75 - 80% of the wires is immersed.
2) Never allow the submerged wires to touch. Spacing between the wires is not critical, but an allowance of 1-1/2" (3.8cm) will produce a slightly higher PPM (parts per million). If the wires are allowed to touch, the process will stop. You can not be shocked by this small voltage when submerging the wires so don't be afraid to touch them.
3) The process starts immediately when the alligator clips are both attached to the submerged wires and stops when either or both clips are disconnected. During the activation process, the light bulb should remain very dim or even completely dark.
4) A three minute activation of 8 ounces properly conductive water at 70oF (21oC) will yield a strength of approximately 3 PPM. Each additional one minute of activation will increase the strength by 1 PPM. Each 10% increase in temperature will double the PPM for a given length of time. A strength of 3 - 5 PPM is optimal. (You may wish to read this excellent article on the importance of the silver particle size by Zane Baranowski, CN.) Water conductivity, the electrodes' surface, amount of current and length of activation time will all vary the PPM of your colloidal silver.
5) Disconnect the alligator clips and wipe the electrode wires clean after each use to remove silver oxide. Using a paper towel to wipe the electrodes while still damp should provide sufficient cleaning.

** Use VERY LITTLE SALT. Use one grain of sea salt per 8 ounces water. Mix with a non-metallic stirrer or spoon. Too much salt will produce silver chloride, not colloidal silver, resulting in a gray, milky or dishwater color. Use only sea salt; table salt contains additives.


If the light bulb glows too brightly while making colloidal silver, too much salt has been added. This solution can be used for household cleaning. The bulb should remain off or glow only very slightly if the solution is to be ingested. Old batteries will also produce a very dimly glowing light bulb. Check your batteries by touching the two alligator clips together. Each set of batteries should make at least 100,000 batches of colloidal silver before replacement becomes necessary.

Checking Your Product:

A laser beam can be used to check for colloidal concentration and purity by viewing the back-scatter of the laser beam as it passes through the solution known as the Tyndall/Raleigh effect.

Storing Colloidal Silver:

Make and store the colloids in non-conductive containers of dark brown glass or opaque plastic - never metal.

Suggested Dosage:

  • Adults--4 dropperfuls once daily, or more, as needed.
  • Children--1 or 2 dropperfuls once daily.
  • May be taken with distilled water or pure juice at least two hours before or after a meal.
  • May be applied topically.

Consuming too much colloidal silver, over time, can result in a permanent graying of the skin - a condition known as argyria.

"Silver has been suggested by some for water treatment and may still be available outside the US. Its use is currently out of favor due to the EPA's establishment of a 50 ppb MCL (Maximum Contaminate Level) limit on silver in drinking water. As the disease requires a net accumulation of 1 gram of silver in the body, one expert calculated that you could drink water treated at 50 ppb for 27 years before accumulating 1 gram Silver has only be proven to be effective against bacteria and protozoan cysts, though it is quite likely also effective against viruses."1

We can not and do not prescribe the proper dosage which should be consumed to achieve the desired health results though these amounts have been suggested. Consult with a naturopath or health food store for proper dosage.

Additional Reading:

For an excellent article on colloidal silver, read Peter Lindemann's, A Closer Look at Colloidal Silver
. While the bulk of the information is detailed and as fine as any I have come across, his slant is definitely not geared toward home production of the product. It may or may not be influenced by the development of his own colloidal silver generator which is for sale. Use your own discretion. However, the article is certainly worth reading.
