This book is a comprehensive, current and objective reference on colloidal silver. It is a thorough review of old and recent scientific and medical literature on the medical and toxicological aspects of silver colloids.Colloidal Silver has been promoted as a wonder cure for all infectious diseases and denounced by the FDA as an unapproved and ineffective drug. So, what are the facts?Up through the 1940's silver medicines were sold in over four dozen forms and used as a near universal antibiotic. They were quickly phased out with the introduction of penicillin and other patented antibiotics. The medical literature on silver medicine from the middle of the 1800's to the middle of the 1900's is extensive. Most of this old literature was collected, analyzed and summarized.There have been numerous informal or anecdotal reports published on the internet. There have also been well documented invitro (in a petri dish in a lab) studies performed on the antimicrobial effects of colloidal silver on many micro-organisms. Some of this data is collected and summarized.There have been informal studies on silver absorption and elimination published only on the internet. There has also been some modern research on the microbiology of silver and silver products. This data has also been collected and summarized.Because of over use, over dosage and the use of more toxic forms of silver medicines, a condition called argyria (staining of the skin by silver deposits) was reported in some patients from the earlier era. A number of prejudicial statements have been made against silver medicine because of the argyria issue. A detailed and objective analysis with all available information is presented. Argyria is easily avoided if it is understood.This book does not give medical advise and does not promote silver use. It also leaves many medical questions unanswered simply because the answers don't exist in published literature. It does present a compilation of a massive amount of available documented information that all individuals interested in silver medicine should have.
