Q and A: Can Silver Be Used to Kill a Werewolf?

15 Dec

Q: My hero knows the villain, a werewolf, is extremely allergic to silver. He has to introduce a sufficient amount into the villain’s system to put him out of action permanently. He doesn’t have to die but no longer be a threat. A vegetative state would be okay.

They are at a party to raise money to rebuild a church. The villain is a member of the church council so will be greeting the guests. The hero and villain have never met before.

The hero cannot be a suspect in the villain’s poisoning so he can’t offer him any food or drink with silver in it. If he gave the villain a check with silver powder sprinkled on it would it be enough to bring on a reaction? How soon would the reaction occur and what would be the symptoms? The party’s host’s son is a doctor. What actions would he take to save the villain?

A: What a wild plot. If I remember correctly from my childhood visits to the Saturday morning “Creature Features” at the local theater, a werewolf can be killed with a silver bullet to the heart. But, silver powder would work too if the werewolf was allergic to it.

A severe allergy to virtually anything can kill the allergic person. From peanuts to penicillin and everything in between. And yes, sliver, too. Particularly in the world of werewolves and other fantasy situations. If the victim is severely allergic, skin contact of a metal such as silver might very well produce a sudden and deadly allergic reaction. This would be called an anaphylactic reaction or anaphylaxis.

Our immune system is critical to our survival. We are constantly bombarded by potential antigens all the time, usually in the form or bacteria and viruses. The body recognizes the antigen (virus, etc.) as foreign and builds antibodies that will recognize and attach to the virus. This reaction attracts white blood cells (WBCS), which release chemicals that kill or harm the virus, which is then consumed by the WBCs and destroyed. This process is essential for each of us to survive in our bacteria and virus-filled world.

So far, so good.

But, in allergic individuals, this reaction can be rapid and massive and can cause the release of large amounts of the chemicals from the WBCs. This is the reaction we call anaphylaxis. In excessive amounts these chemicals cause dilatation (opening up) of the blood vessels, which leads to a drop in blood pressure (BP) and shock. They cause the bronchial tubes (airways) to constrict (narrow), which leads to shortness of breath, wheezing, and cough. This is basically a severe asthmatic attack and prevents adequate air intake and the oxygen level in the blood drops rapidly. The chemicals also cause what is known as capillary leak, where the microscopic blood vessels in the tissues leak fluids into the tissues. This leads to swelling. In the skin this is manifested as hives and rashes. In the lungs it causes swelling of the airways, which along with the constriction of the airways, prevents air intake. In the tissues it causes swelling of the hands, face, eyes, and lips. The net result of an anaphylactic reaction is a dramatic fall in BP, severe wheezing, swelling and hives, shock (basically respiratory and cardiac failure), and death.

So, anaphylaxis is a rapid and profound reaction to some antigen. These antigens are typically foods, drugs, or insect venoms. Common foods are peanuts and shellfish, common drugs are penicillin and iodine, which is found in many radiographic dyes, and common insects are bees. There a myriad other foods, drugs, and bugs that can cause anaphylaxis in the allergic person. And in your scenario, silver would work.

Usually anaphylaxis onsets within minutes (10 to 20) after contact with the chemical, but sometimes, particularly with ingested foods, it may be delayed for hours—even up to 24 hours. In your scenario it would take from 10 to 30 or so minutes to begin and your werewolf would then develop all the above symptoms and signs. He would become very short of breath and develop hives and a rash. He might wheeze and gasp for breath. Finally he might clutch his chest and collapse into shock and die.

Untreated anaphylaxis leads to death in anywhere from a very few minutes to an hour or more, depending upon the severity of the reaction and the overall health of the victim. Treatment consists of blood pressure (BP) and respiratory support, while giving drugs that counter the allergic reaction. BP support may come from intravenous (IV) drips of drugs called vasopressors. The most common would be Dopamine, Dobutamine, epinephrine, and neosynephrine. Respiratory support may require the placement of an endotracheal (ET) tube and artificial ventilation. The victim would immediately be given epinephrine IV or subcutaneously (SubQ) and IV Benadryl and steroids. Common steroids would be Medrol, Solumedrol, and Decadron. These drugs work at different areas of the overall allergic reaction and reverse many of its consequences. The victim could survive these interventions. Or not. Your call. And if he survived he could easily suffer permanent brain damage and be in a vegetative state.

    My understanding is that werewolves don’t respond well to vasopressors and steroids, but my sources may be suspect.

      I think it’s due to inbreeding and recessive genes.

      Some of the things I read in the Laurel Hamilton Anita Blake books are interesting. One book I read, they talked about fellowships in Preternatural obstetrics.

    In this (admittedly fantasy) situation, wouldn’t a bit of colloidal silver in the party’s punch be enough? I am assuming the possibility of it being a allergen to anyone other than the werewolf would be low enough to keep the hero from worrying about collateral damage. Or at least it could be written that way.

    I understand that long-term use of colloidal silver is potentially hazardous to one’s health, but I doubt a single use like this would be a problem for the majority of folks. It’s a commonly available substance in health food stores, and might fit the bill.

    A thought, anyway.

      Absolutely, a little silver never hurts unless you are allergic or are exposed to a large dose or repeated small doses and anaphylaxis to silver is rare anyway. It works in SciFi and fiction but in real life is rare–except for minor allergies to jewelry, etc. There are several Indian dishes where very thin gold or silver is layered over the food. The ones I’ve had added no taste that I could detect but it was very cool.

      Chronic silver poisoning is called Argyria. When I was in med school there was a guy that worked at the VA hospital who had this–I think from working in a silver mine if I remember correctly–but he was silver. Not gray, silver. His skin and hair glistened. He reminded me of the silver crayon in the Crayola pack. That’s the only case I’ve ever seen. Check it out on Wikipedia and you’ll see pictures. One of the pics is of a guy as silver as the fellow I knew.

        Remember when taking Colloidal Silver was the fad of the week?

    A woman who frequented a restaurant my father owned for a few years, had a pronounced green tint to her skin, like a Vulcanian or Romulan from Star Trek. I’m not sure what caused it. She is still around and looks less avocado than she did at one time, so I’m assuming she received some sort of treatment for the condition.

    Sorry… straying from the topic.

      There are a few things that could cause this. Exposure to certain copper salts can do it. I also found one report of green pigmentation from FD&C Blue No. 1 dye added feeding tube food preparations to look for signs of pulmonary aspiration of food materials given through a feeding tube in hospitalized patients.

        One hospital I worked at, we used blue food dye, which turned stool greenish-blue, as well as the skin the stool touched (and it never came off the skin, kinda like pyridium orange). Another hospital I worked at, we used methylene blue, which did nothing to the stool. but turned the urine blue. That was years ago when I worked in ICU. I don’t think they color the tube feedings anymore, I think it caused more problems than it prevented.

    I was reading a series of books, where the Vampires were allergic to silver and sunlight. They had developed drugs to allow them to function in daylight, but they still had problems with the silver. I’m on the road, right now but when I get home, I’ll find them and get back to you.

      Fascinating scenario. Can’t wait to hear more.

      The books are by Susan Sizemore and her main characters are vampires.

    What about putting a silver suspension mixed with perfume in an atomizer? And just ‘accidentally’ spray some around the werewolf so he’d end up getting part of it, in a way that it would seem that you didn’t really mean for any to get on him? (saw this used in a Harry Potter fanfic about a potion someone wanted to hit Voldemort).
