How to get rid of your cold with mouthwash
Measure the amount of mouthwash recommended by the manufacturer and pour into a clean cup.
Typically, the recommended amount is 4 teaspoons (20ml). However, make sure that you check the label of your mouthwash before measuring.

Available options: (a). You'll want the added water to be approximately 4 liters (19 l). Add 2 to 3 tablespoons of baking soda. (b). Do not swig mouthwash directly from the bottle, especially if you are feeling sick. There is no way of knowing if you have taken the correct dosage. (c). You can order mouthwashes in your pharmacy or similar place, but be sure to also ask the pharmacist for help with measuring. If the product seems way out of place, try asking around at a local health food store and see what they carry. (d). If you wish to use store-bought mouthwashes, then you will need to get into the store and order a cup before rolling it up. Too much or too little will minimize the effectiveness of your mouthwash and prevent symptoms from rising.
