What is saline solution?
Saline solution is a mixture of salt and water. Normal saline solution contains 0.9 percent sodium chloride (salt), which is similar to the sodium concentration in blood and tears. Saline solution is usually called normal saline, but it’s sometimes referred to as physiological or isotonic saline.
Saline has many uses in medicine. It’s used to clean wounds, clear sinuses, and treat dehydration. It can be applied topically or used intravenously. Saline solution is available at your local pharmacy, but it can also be made at home. Read on to learn how you can save money by making your own saline.
Saline solution is easy to make and can be done using things you already have in your kitchen. You’ll need:
- tap water
- table salt or fine sea salt (iodine-free)
- a pot or microwave-safe bowl with a lid
- a clean jar
- a measuring cup and teaspoon
- baking soda (optional)
Before you begin, prepare a jar to store your saline solution in. Wash the jar and lid thoroughly with hot water and soap or run it through the dishwasher. This will help prevent bacteria from contaminating your solution.
- Boil 2 cups of water covered for 15 minutes.
- Allow to cool to room temperature.
- Add 1 teaspoon of salt.
- Add 1 pinch of baking soda (optional).
- Stir until dissolved.
- Refrigerate in airtight container for up to 24 hours. (After that, it should be discarded.)
- Add 2 cups of water to a microwave-safe container.
- Mix in 1 teaspoon of salt.
- Microwave, covered, for 1 to 2 minutes.
- Allow to cool.
- Place in a clean jar.
- Refrigerate for up to 24 hours.
The stovetop method is more sterile than the microwave method, because the water is boiled. For both these methods, however, bacteria can begin to grow after 24 hours.
If you want a more sterile and longer-lasting version, you can use distilled water. Distilled water can be purchased at your pharmacy or grocery store. It’s also possible to distill water at home.
- Add 8 teaspoons of table salt to 1 gallon of distilled water.
- Refrigerate for up to 1 month.
Saline solution makes an excellent nasal wash. When flushed through your nasal passages, saline can wash away allergens, mucus, and other debris. Nasal irrigation can relieve the symptoms of stuffy nose and help prevent sinus infections.
A neti pot or nasal bulb can make nasal irrigation easier. You can also use things from around your house such as a turkey baster or a squirt bottle. Just make sure to wash these items thoroughly with hot, soapy water or run them through the dishwasher.
To clear your sinuses:
- Hold your head over the sink or get in the shower.
- Tilt your head to the right.
- Pour or squeeze the saline solution into the left nostril (the solution should pour out your right nostril).
- Repeat on the opposite side.
- Adjust your head position if water is going down the back of your throat.
Soaking a new piercing in saline is one of the best ways to promote healing and prevent infection. Saline helps clear away dead cells and other debris that can cause irritation and lead to crustiness and bumps. Warming up the saline helps increase blood flow to the site.
Soak a new piercing in warm saline for 5 minutes once or twice per day. The saline should be about the temperature of hot coffee.
Depending on where your piercing is, you can put the saline in a mug, bowl, or shot glass. You can also soak a clean cloth and apply the cloth to the piercing site. After soaking your piercing, rinse it off with clean water.
Saline can be used to help wash out uncomplicated cuts and wounds. Pouring saline on a wound can help clear away foreign material and bacteria, reducing the likelihood of infection. Normal saline solution will not sting or burn a wound.
Although saline solution is a good option for wound cleaning,
