Colloidal Silver is a natural and powerful broad spectrum antibiotic agent, it also has excellent antiseptic, antifungal and disinfectant properties. As long ago as 400 B.C. Hippocrates described colloidal silver’s antimicrobial properties. In addition to having antibiotic properties, new studies have demonstrated that silver is one of the most effective substances for fighting antibiotic resistant super-pathogens such as MRSA.
From the late 1800s up until 1938 Colloidal Silver was commonly prescribed to treat a wide spectrum of diseases and infections. With the advent of man-made antibiotics in the late 1930’s, Colloidal Silver lost its popularity. Read here for more information on the history of Colloidal Silver.

The big pharmaceutical companies have done an effective job lobbying the FDA to strike a ruling to discredit the confirmed efficacy of Colloidal Silver as a natural antibiotic, anti-fungal and anti-viral agent. However extensive research performed by Dr. Robert O. Becker proved the healing properties of silver ions contained in silver.  Read here about how the International Space Station and the Russian Space Station utilized Colloidal Silver. 

How Colloidal Silver is Made

  • Pure silver will not dissolve in water;
  • Pure silver will dissolve and float permanently in water if a process is employed that:
    • Divides the silver into single atoms of micro-clusters of less than 15 atoms each;
    • Gives the atoms a positive electrical charge;
    • Attaches the atom to a molecule of simple protein;
  • This process is called colloidal suspension;
  • As the force of the electrical charge is stronger than gravity the silver particles remain suspended;
  • True Colloidal Silver is a colorless liquid (not yellow) becasue the micro-clusters are too small for light from the micro-cluster to reflect back to the human eye.

How Colloidal Silver Kills Virus, Fungus and Bacterium

(one-celled disease causing pathogens)

Colloidal Silver cripples the pathogens oxygen-metabolising enzyme (chemical lung) causing suffocation and death of the pathogen – this process typically occurs within six minutes. Disease organisms can become resistant to conventional antibiotics (triggering super-infections) as pathogens have enough time to mutate allowing the organism to become immune to the antibiotic during the period of time in which the antibiotic takes effect. Because colloidal silver works at a faster pace pathogens do not have the opportunity to mutate so there is no risk of immunity occurring.

How Colloidal Silver Speeds Healing

Robert O. Becker discovered how colloidal silver actually works to speed healing. Colloidal silver creates a condition in which usual cell division (mitosis) in body tissue is altered to create one duplicate cell and one dedifferentiated cell.
The dedifferentiated cell:

  • Is like a blank template that can change into any type of cell in the body;
  • Will naturally migrate to a part of the body where tissue damage exists;
  • Once there the cell transforms to the characteristics of the local tissue type cell where it then supports normal cell repair in the injured area and will also lessen scar tissue formation.
How Colloidal Silver Works to Kill Fungus

Fungus is comprised of a series of single cells which –like a single cell bacterium; has a chemical lung that is permanently disabled by the presence of Colloidal Silver.

How Colloidal Silver Works to Kill Viruses

A single virus cells invades a living cell of body tissue and then takes over the nucleus of the living cell and alters its re-productive mechanism to reproduce the virus rather than producing what it was originally intended to produce – i.e. enzymes, hormones, and other necessary chemicals. The virus is then released into the bloodstream. When the virus attacks the cell, the living cell transforms back to a more primitive cell structure which is vulnerable to the effects of Colloidal Silver.

Topical Uses for Colloidal Silver

For topical treatment you can use either the gel form or liquid form of Colloidal Silver...
    • Will not sting when applied topically to wounds, abrasions etc. as colloidal silver kills topical germs without harming surrounding tissue;
    • Is non-toxic to dogs and cats unless it is ingested in substantial quantities over a long period of time – in which case it could cause liver and/or kidney problems;
    • Does not have any known interactions with drugs or herbs; 
    • Is non-allergenic, it does not react chemically on or within the body and therefore cannot trigger an allergic reaction...

Abrasions, Cuts and Wounds - Disinfect and Speed Healing
  • Apply Colloidal Silver directly to the wound and if you are applying a dressing (wrap or bandage) apply a little Colloidal Silver to the dressing as well;
  • As Colloidal Silver will not react with other medications it can be used with another medication.
Canine Acne - Treating and Healing
  • Use a small piece of a cotton ball, massage a small amount of Colloidal Silver in to the problem areas two to three times a day.
Conjunctivitis (Pink-eye) - Treating and Healing
  • Drop 2 to 3 drops of Colloidial silver water into the eye 2 to 3 times a day;
  • You can also use Colloidial silver gel – line the underside of the eye with a thin strip of the gel 2 to 3 times a day.
Ear Infections - Treating, Reducing Inflammation, Healing
  • For ear infections place 3 to 5 drops of Colloidial Silver water into the ear canal 2 to 3 times a day;
    • Gently rub/massage the ear in a circular motion, then remove your hand and let your dog/cat shake its head;
    • You can use a cotton ball to gently wipe any excess liquid off the inside of the ear flap;
    • If you need to use a cotton swab to clean more precisely - never put the cotton swab past the portions of the ear that you can readily not put the swab into the ear canal - you can very easily damage the ear drum either temporarily or permanently!
    • Do not use any of these treatments if your animal's ear drums are perforated/punctured;
  • Swab the inner-ear flap with Colloidial Silver water or gel once or twice a day;

Hot Spots, Skin Rash - Treating and Healing
  • Use a cotton ball to apply (dab) Colloidal Silver directly onto the affected area – rub gently. Repeat several times daily.
Insect Bites - Treating and Healing
  • Use a cotton ball to apply (dab) Colloidal Silver directly onto the affected area – rub gently...
  • To sooth bites and sting sites;
  • To disinfect after  removal of, i.e.:
    • Blow fly larvae;
    • Ticks;
    • Rash from flea bites; 
    • Etc.
Periodontal Issues, Infected Tooth, Bleeding Gums - treating, healing
  • Topical Treatment
    • Use a cotton ball to apply (dab) Colloidal Silver directly onto the affected area – rub very gently;
    • Repeat several times daily;
  • Ingested Treatment:
    • If the infection/inflammation is severe you may also want to administer an ingested treatment of Colloidal Silver;
    • See dosage provided under 'Ingested Uses For Colloidal Silver' below.

Ingested Uses for Colloidal Silver

For ingested treatments use the liquid form of Colloidal Silver... 
    • Colloidal Silver takes five (5) to seven (7) days - on average, for the initial benefits of ingesting Colloidal Silver to start taking effect;
    • By the tenth (10th) day - on average, Colloidal Silver builds up in the body tissues to at least a concentration of five (5) parts per million (ppm); 
      • Body tissue that contains 5 ppm of Colloidal Silver will be free of virus, fungus and bacterium;
    • Some dogs and people :>) may show some signs of achiness or sluggishness on the 3rd of 4th day into ingested treatment as the Colloidal Silver works to eliminate a significant amount of toxins from the body;
      • This occurs when there are many toxins present in the body and the eliminatory organs (i.e. bladder, kidney, liver) become overloaded trying to pass the toxic matter;
      • To avoid this make sure you encourage your dog to drink more fluids during treatment;
      • One to three weeks after ceasing the treatment, the efficacy of the Colloidal Silver build-up has dissipated as the silver leaves the body via the kidneys, lymphatic system and bowels;
    • The daily intake (dosage) is provided below;
      • For treating an active infection or ailment, treatment is 2 to 3 times daily for 10 consecutive days, after which point the course of treatment is complete.
Caution Regarding Ingested Treatments

If your dog suffers from renal issues placing additional burdens on your dog's kidney's, liver, and badder is not a good idea - so consult with your veterinarian before you use colloidal silver.

Selecting a Good Quality Colloidal Silver

  • Colloidal Silver can be purchased in a liquid or gel form - choose according to how you intend to use it:
    • If you want to use it strictly as a topical treatment you can use the gel of liquid form;
    • If you want to use it as an ingested treatment use the liquid form.
  • Make sure you purchase your Colloidal Silver from a reputable source;
  • Colloidal Silver keeps best in glass, so look to purchase Colloidal Silver that is sold in a glass jar rather than in a plastic bottle;
    • When packaged in plastic Colloidal Silver has a much shorter shelf-life;
  • Don’t store Colloidal Silver in the refrigerator or freezer as the electric charge of the appliance can reduce the efficacy of Colloidal Silver just as storing it in plastic may do;
  • The best quality Colloidal Silver does not contain any stabilizers or other additives, and should not list any trace elements other than silver on the product label. It should not need to be shaken before use and should not need to be refrigerated;
  • You can use Colloidal Silver water and/or gel;
And despite what you may have hear or read in the past...

Colloidal Silver should NOT be yellow in colour. As noted further above true Colloidal Silver is a colorless liquid (not yellow) because the micro-clusters are too small for light from the micro-cluster to reflect back to the human eye...

Many manufacturers unwittingly create their product under the false pretense that Colloidal Silver should be yellow in colour. To create the colour they will add food colouring (artificial food colouring is a toxin and carcinogen) or other colouring agents. 

The colour of Colloidal Silver will be yellow under the following undesirable conditions:
  • The silver used is;
    • A silver sulphide type of silver that is primarily used in making ceramics - this is not a desirable quality of silver for use in Colloidal Silver;
    • Silver Oxide which is brownish-black in colour and is also not a desirable quality of silver to use;
  • The particles of silver are to big in size - which will make the product much less effective;
  • If the silver losses its colloidal state (suspension) and precipitates out of the solution (will have a black tinge) the product will lose its efficacy and should be disposed of - contrary to what some people advise, shaking the solution will not bring the particles back to a colloidal state;
  • If food colouring or other colouring agents have been used.
  • Do not purchase or use products that have any of these attributes as they are inferior in quality!

Where to Purchase Colloidal Silver
  • Health and Natural Food Stores;
  • Herbal and Homeopathic Stores;
  • Organic Health Stores;
  • Pharmacies.
