Colloidal silver benefits can be somewhat controversial. Some speculate that it has no known properties, while others swear by it.
 
On a personal note, I will give you a testimonial on how Silver has worked in our family. Since the day my daughter was born, we put a silver necklace with a tree around her neck. As she was teething, she tends to find anything she could put in her mouth to soothe her gums. I talked to other moms and could not account for any time that she was down with a cold or got a diarrhea spurt or anything.
As a wellness practitioner, I spend a lot of time researching when I read about Colloidal Silver; it made sense why viruses, bacterias, or fungi did not adversely affect my child. We believe it was because she sucked on her silver necklace, and the silver particles leeched into her system.

So this is what we found out about Colloidal Silver. Silver holds onto oxygen molecules; it responds to sulfhydryl (H) organisms that surround bacterial and viral infected cells. A study showed a positive outcome when Colloidal Silver entered into a gram-negative bacterium Pseudomonas Aeruginosa (commonly affects humans and animals) and other multi-drug resistant bacteria. The research is confirming that it is well suited for its use in clinical and therapeutic applications (Dakal, Kumar, Majumdar, & Yadav, 2016).
But what are the benefits of Colloidal Silver? Colloidal Silver is an anti-bacterial; it can fight antibiotic-resistant bacteria Dr. Larry C. Ford was able to show the destruction of  650 different diseases with the use of Colloidal Silver (UCLA, 2012).

Another study performed in 2015 examined the benefits and the capability of Colloidal Silver, as a bactericidal and antibiotic, examining its synergistic effect against MRSA (Abdel, & Ali Mohamed, 2015). The result explained that Colloidal Silver inhibited the bacterial growth of MRSA, showing almost all of the cells died within four hours  (Abdel, & Ali Mohamed, 2015).
Colloidal Silver in years has provided an alternative and support for immunity, fighting against numerous types of bacteria, parasites, and other infectious diseases. Studies have proven over and over again, the benefits of ingesting or applying minute amounts of Silver.  Bacterias, fungi, and viruses that cause colds, flu, candida, inflammation, etc. have no chance against these micro-organisms.
