Uses of Saline Solution
In stead of using expensive and actually useless commercial mouth rinses that contains alcohol, chlorhexidine, cetylpyridinium, or antiseptics for irrigation and cleaning wounds that contains chlorhexidine and/or cetrimide, etc. rather use a saline solution (just plain UNiodised (NO iodine) table salt - sodium chloride in water) - do not use sea salt or any other "fancy" salts which contain have some or other unnecessary added minerals or other chemicals. To use as a mouthwash or gargle just add a half a teaspoon table salt to a cup/glass(250ml) of lukewarm water - stir well until the salt dissolves - pour the saline mouthwash into a as sterile as possible bottle and close the lid - discard by the end of the day. To clean wounds or irrigate your sinuses "normal saline" must be used, which is .9% (point nine percent - just less than 1%) of sodium chloride in water, That would be 9 grams (just less that two level teaspoons) of sodium chloride per litre (1000 ml) of water. Dissolve the sodium chloride in a litre of boiling water. Let it cool off keeping it covered to keep it sterile - store in sterile container with a tight lid - never contaminate contents, by pouring any unused portion back into it, or leaving the container uncovered/unsealed etc. Discard after a few days. Using a saline solution just once a day can help thin mucus, decrease postnasal drip, and clean bacteria from your nasal passages. It can also wash out allergens you've inhaled. After symptoms are gone, some people find three times a week is enough to keep them symptom free. Do not use as a contact lens solutions - except in case of extreme emergency.
