Say you want to stock up on Saline Solution and the price of it is a bit too steep or you can't find any... You can easily make your own.
With all of this contamination going around it's not a bad thing to know how to do or to have some on hand for an emergency. Whether it be from the Ebola scare, Flesh Eating Bacteria scare on our beaches, or the Antibiotic Resistant bacteria probabilities we keep hearing about, this solution will have it's uses.
Saline solution refers to a salt solution, which you can prepare yourself using readily available materials. The solution can be used as a disinfectant, sterile rinse, or for lab work. This recipe is for a salt solution that is normal, which means it is the same concentration or isotonic to body fluids. The salt in saline solution discourages bacterial growth while rinsing away contaminants. Because the salt composition is similar to that of the body, it causes less tissue damage than you would get from pure water.
Technically, a saline solution results whenever you mix any salt with water. However, the easiest saline solution consists of sodium chloride (table salt) in water. For some purposes, it's fine to use freshly mixed solution. In other cases, you'll want to sterilize the solution. Keep the purpose in mind when you mix the solution. If, for example, you are simply rinsing your mouth with saline solution as a dental rinse, you can mix any amount of table salt with warm water and call it good. If, however, you are cleaning a wound or want to use the saline solution for your eyes, it's important to use pure ingredients and maintain sterile conditions.
You can use salt from the grocery store. It's best to use uniodized salt, which does not have iodine added to it. Avoid using rock salt or sea salt, since the added chemicals may cause problems for some purposes.
Use distilled water or reverse osmosis purified water over ordinary tap water.
You want 9 grams of salt per liter of water or 1 teaspoon of salt per cup (8 fluid ounces) of water.
Prepare the Saline Solution -
As a mouth rinse, you can simply dissolve the salt into very warm water. You may even wish to add a teaspoon of baking soda (sodium bicarbonate).
For a sterile solution, dissolve the salt in boiling water. Keep the solution sterile by placing a lid over the container so that no microorganisms get into the liquid or air space as the solution cools.
You can dispense the sterile solution into sterile containers. Sterilize containers either by boiling them or my treating them with a disinfecting solution, such as the type sold for home brewing or making wine. It's a good idea to label the container with the date and to discard it if the solution is not used within a few days. This solution could be used for treating new piercings or for wound care. It's important to avoid contaminating the liquid, so ideally make just as much solution as you need at a time, allow it to cool, and discard leftover liquid. The sterile solution will remain suitable for lab use for several days in its sealed container, but you should expect some degree of contamination once it is opened.
