A search of the medical literature did not reveal any scientific studies 
that support the effectiveness of colloidal silver preparations. Colloidal 
silver is potentially harmful and, in fact, the Food and Drug 
Administration has issued a Final Rule that "all over-the-counter drug 
products containing colloidal silver or silver salts are not recognized as 
safe and effective and are misbranded." (To read the Talk Paper that 
explains the Final Rule, see 
).  "According to the Final Rule, a colloidal silver product for any drug 
use will first have to be approved by FDA under the new drug application 
procedures.  The Final Rule classifies colloidal silver products as 
misbranded because adequate directions cannot be written so that the 
general public can use these drugs safetly for their intended purposes.  
They are also misbranded when their labeling falsely suggests that there is 
substantial scientific evidence to establish that the drugs are safe and 
effective for their intended uses.  The indiscriminate use of colloidal 
silver solutions has resulted in cases of agryria, a permanent blue-gray 
discoloration of the skin and deep tissues." (FDA Talk Paper, FDA Issues 
Final Rule on OTC Drug Products Containing Colloidal Silver).  This ruling 
by FDA means that companies selling colloidal silver may be subject to 
legal action.
