Overview
Colloidal silver is a commercially sold product that contains microscopic flakes of pure silver. Usually the flakes are suspended in demineralized water or another liquid. This form is marketed for oral use.
Colloidal silver is often touted as an antibacterial agent and a topical wound dressing. Some people claim it can cure a cold faster, heal the body better, and even treat cancer or HIV.
But does colloidal silver really strengthen your immune system? Is it actually safe for everyday use? Keep reading if you’re considering using colloidal silver.
Colloidal silver is a popular product in holistic health circles.
But in 1999 (and again 10 years later), the Food and Drug Administration (FDA) issued a press release stating that there was no evidence to suggest a clear health benefit for colloidal silver. Rather, there’s evidence of some risks associated with using colloidal silver.
The National Institutes of Health (NIH) warns that people taking colloidal silver may be actually risking their long-term health for a product that doesn’t improve immunity or promote healing.
Clinical trials are ongoing into the use of oral colloidal silver, as well as the use of negatively charged silver nanoparticles for topical use on wounds.
The use of silver taken by mouth can’t be recommended. Over time, colloidal silver can build up in the tissues of your body and give your mucous membranes and skin a grayish appearance. This is a symptom of a condition called argyria.
Agyria isn’t reversible. Argyria by itself isn’t dangerous, and is defined as being “medically benign.” Of course, any skin discoloration isn’t exactly a welcome side effect.
Colloidal silver also interferes with your body’s absorption of certain drugs. These include antibiotics and thyroid deficiency medication.
If you’re prescribed an antibiotic for a bacterial infection, taking colloidal silver might prevent that prescription from working effectively. That means taking silver would actually keep you feeling sick for longer.
Nursing and pregnant women who try colloidal silver as an alternative to some cold and flu drugs should keep in mind that no trial has ever proven colloidal silver to be safe for a developing baby. When things aren’t proven safe, they can’t be recommended for use.
There have been some benefits from applying silver-containing ointments to the skin. Health claims of topical silver include:
Topical colloidal silver products claim to be antimicrobial, germ-fighting agents. At least one clinical study indicates that this claim may be questionable. Other studies show some promise when silver nanoparticles are incorporated into bandages and dressings for wounds.
Colloidal silver is also claimed to promote healing of skin wounds. According to a 2007 study, silver-containing wound dressings are a more effective barrier against infection than other products that make similar claims.

The NIH also supports the idea that colloidal silver can be an effective topical wound dressing.
Colloidal silver is an ingredient in some acne treatments and cosmetics. It’s also sometimes used in an eye drop formula to prevent conjunctivitis in newborns.
As long as colloidal silver is used topically and in small amounts, it doesn’t pose a great risk of argyria.
The Environmental Protection Agency (EPA) estimates that most people are already exposed to silver every day in their environment.
Silver isn’t a vitamin or mineral that naturally occurs in the body. You don’t need to make sure you’re getting an adequate dose of silver or do anything to make up for not being exposed to it.
A dosing reference chart created by the EPA suggests that your daily silver exposure — topical, oral, or environmental — shouldn’t exceed 5 micrograms per every kilogram you weigh.
Colloidal silver’s most common commercial form is as a liquid tincture. Most health food stores carry it. It can also be bought as a powder to apply to your skin. Some people even make their own colloidal silver at home, using a special machine.
Colloidal silver is a classic example of anecdotal reports that differ drastically from scientific research. Always remember that oral colloidal silver isn’t a product that’s regulated by the FDA.
Companies that claim that colloidal silver is a miracle cure for diseases such as cancer and HIV are doing so without any clinical proof. There are many other safe options for staying healthy, preventing disease, and getting better from illness.
If you decide you’d like to try colloidal silver, check to make sure that it won’t interact with any prescriptions you’re taking. Consider topical use with guidance from a healthcare professional. Never exceed the dosing recommendations put forward by the EPA.
If you experience side effects at any point, such as nausea or skin discoloration, stop using colloidal silver immediately.
Technical field the present invention relates to a kind of nanometer silver antimicrobial powder preparation, and its main component is that 1--25 nano-silver powder, discrete agent are mixed into mixture in proportion.Nano-silver antibacterial powder can be used for the antibiotic and sterilizing of various industries, every field, various article.Adopt antibacterial agent directly to sneak into and make fibrous raw material production antibiotic, sterilize cloth, cotton, antimicrobial filtering nethike embrane, antibiotic bed mattress and cushion and shoe-pad etc. in the high molecular polymer.Also can be used for producing other high-quality cotton spinning industries.Make the nano-silver water solution of various concentration, can soak oven dry by the easiest dilution and handle, can produce durable, the antibacterial fabric that antibacterial effect is extremely strong.The textiles such as cloth that become with the Nano Silver silk weaving have same effect.Nano-silver powder all has stronger inhibition and killing action to several 10 kinds of pathogenic microorganismss such as Escherichia coli, staphylococcus aureuses.As brand-new anti-infective product, this nano-silver antibacterial powder is different from all anti-infectives at present, has wide spectrum, has no drug resistance, multiple performance such as acid and alkali base number influence.Existing antimicrobial product kind is a lot, and the active ingredient of high-efficient antibacterial agent and content are directly proportional with price often; And toxic, corrosivity, penetrating odor have pollution to environment, to being sterilized article certain damage are arranged.Therefore, every profession and trade is wished that always a kind of antimicrobial efficiency height can be arranged, wide spectrum, is had no drug resistance, the influence of acid and alkali base number, safety and stability, environmentally safe, article are not had the nanoscale product of damage.
Background technology the object of the present invention is to provide a kind of nano-class antibacterial preparation that can overcome the existing procucts deficiency, has antimicrobial efficiency height, has a broad antifungal spectrum, has no drug resistance, good stability, the influence of acid and alkali base number, security performance height, do not have the antibiotic powder product of environment-protection nano silver of damage, characteristics such as of many uses to human body nonhazardous, environmentally safe, to article.
Summary of the invention main points of the present invention are to select suitable component, and rationally are mixed, and make the nano-silver water solution of various concentration, form the nanometer silver antimicrobial powder preparation through technologies such as a series of dilutions, immersion, oven dry, post processings.
The prescription following (component and percentage by weight % thereof) that the present invention selects: 1-25 nano-silver powder (10-30); Discrete agent (10-18); Pure water adds to 100.
Nano-silver powder is as main antibiotic and sterilizing component.This component silver ion is with after bacterium contacts, arrive microorganism wall, positively charged Nano Silver is adsorbed on the electronegative cell wall, rely on Coulomb attraction that both are firmly adsorbed, silver ion penetration cell wall enters in the cell, with-the SH radical reaction, make protein coagulating, microbial cell is broken and death.It can influence the transmission of the required base substance of microorganism, destroys the activity of cell synzyme, stops microbial reproduction with the form of interrupting dna replication dna.Influence the basal metabolism of cell transfer system, cell is lost the division growth ability and death.After thalline lost activity, silver ion can dissociate out from thalline again, repeats fungicidal property, and antibacterial effect is lasting.
