Is silver safe as a medicine?


Effects of colloidal silverThe short answer to that headline question – based on everything I’ve read of late – is no. It’s not that silver has no medical uses – one form has been used in dressings and bandages as an antiseptic (not, as is sometimes claimed, an antibiotic). Silver nitrate is sometimes used to treat warts and corns.

However, the benefits and long-term risks of silver in any form – especially an ingested form – have been not been fully researched.

It’s not that colloidal silver – an entirely different product from topical silver – may not have health-related benefits. It’s just that we don’t really know because there is no solid, peer-reviewed research to back up any of the claims. And those claims make it nothing short of miraculous. Quackwatch lists AIDS, chronic fatigue, herpes, TB, syphilis, lupus, malaria, plague, acne, impetigo, and Lyme disease among the diseases sellers claim their colloidal silver will cure. Others include “Common cold, stomach ulcers, acne, burns, shingles, arthritis, strep, tuberculosis,” fungus, bacteria, polio and cancer.

A 2013 study found colloidal silver (silver ions) improved the efficiency of antibiotics. But the study’s authors warned that this was just a preliminary effort:

Before adding silver to antibiotics, “we’ll have to address the toxicity very carefully”, says Fowler. Ingesting too much silver can also cause argyria, a condition in which the skin turns a blue-grey colour — and the effect is permanent.

Collins says that he and his colleagues saw good results in mice using non-toxic amounts of silver. But, he adds, there are ways to reduce the risk even further. “We’re also encouraging people to look at what features of silver caused the helpful effects, so they can look for non-toxic versions,” he says,

Silver is used in water purification: “The World Health Organization includes silver in a colloidal state produced by electrolysis of silver electrodes in water, and colloidal silver in water filters as two of a number of water disinfection methods specified to provide safe drinking water in developing countries.” That doesn’t mean that it’s safe to drink the stuff from a bottle.

Rosemary JacobsArgyria is an irreversible effect that comes from ingesting too much silver. It turns your skin cyanotic: blue-ish; from the bright blue face at the top of this post to the slate-grey face of Rosemary Jacobs shown here. Jacobs was given colloidal silver by her doctors and ended up with her discoloured skin. her story is tragic but illustrative – and a lot more real than the anonymous “testimonials” on many of the sellers’ sites.

My caution is mostly because of the charlatans in the alternative-health industry and how they promote their products.

Without considerable effort and research on the part of the consumer, it’s difficult – if not impossible – to determine which product is actually what it claims and is safe. My spidey-sense warns me that if it’s so hard to be sure, it’s best to avoid the product entirely.

Far, far too many of the sites that claim research or proof of colloidal silver’s efficacy as a cure point back to one another site that promotes colloidal silver – usually companies or individuals selling related products. Talk about a conflict of interest! Their “testimonials” are often unsubstantiated and anonymous. As Science-Based Medicine notes;

What perpetuates the use of colloidal silver are testimonials, like the nurse who suggested silver to prevent H1N1. The interwebs are filled with unsubstantiated testimonials, for common infections and unusual infections, with one gentleman crediting colloidal silver, rather than the vancomycin and gentamyin, for the cure of his subdural empyema (pus between the brain and skull).

What do we know about Bell’s Palsy?


Bell's PalsyBell’s Palsy is one of those rare ailments, and one that annoys more than threatens, but can be difficult and socially awkward for sufferers. It’s also one that still baffles researchers as to its cause. And also for an effective treatment.

According to facialpalsy.org,

The name ‘Bell’s palsy’ comes from 19th-century Scottish anatomist and surgeon Sir Charles Bell, who discovered that severing the seventh cranial (or facial) nerve causes facial paralysis.

It has no vaccine, no known method for prevention, and the treatment is still uncertain.

Wikipedia tells us:

Bell’s palsy is a form of facial paralysis resulting from a dysfunction of the cranial nerve VII (the facial nerve) causing an inability to control facial muscles on the affected side… Bell’s palsy is the most common acute mononeuropathy (disease involving only one nerve) and is the most common cause of acute facial nerve paralysis (>80%)… The hallmark of this condition is a rapid onset of partial or complete paralysis that often occurs overnight.

It also says:

It is thought that an inflammatory condition leads to swelling of the facial nerve. The nerve travels through the skull in a narrow bone canal beneath the ear. Nerve swelling and compression in the narrow bone canal are thought to lead to nerve inhibition, damage or death…
Some viruses are thought to establish a persistent (or latent) infection without symptoms… Reactivation of an existing (dormant) viral infection has been suggested as a cause of acute Bell’s palsy. Studies suggest that this new activation could be preceded by trauma, environmental factors, and metabolic or emotional disorders, thus suggesting that a host of different conditions may trigger reactivation.

Which, in essence, doesn’t tell us a lot about the actual cause or why it recurs; mostly it remains guesswork. Bell’s Palsy affects about 20 people per 100,000 population, and the incidence increases with age and with certain medical conditions.
