Angina is a well-known disease in which the tonsils and nearby mucous tissues become inflamed. Angina is characterized by a sore throat, difficulty swallowing, high temperature and general poor health. Of the many folk remedies, soda is most often used for angina - this medicine is affordable, it is always at hand, and it is safe, which is important (especially if children are sick).
Using soda for tonsillitis significantly speeds up recovery and helps to overcome the infection that caused the disease in a short time.
Can you gargle with baking soda if you have a sore throat?
Gargling with soda for tonsillitis is not only possible, but even necessary:
- soda helps to remove microbial plaque from the mucous membrane, which allows you to get rid of a huge number of bacteria;
- soda washes out purulent blockages, in which infections often settle;
- soda alkalizes the environment in the throat, which is not suitable for the development of pathogenic microorganisms;
- Soda reduces signs of inflammation and relieves pain.
Soda for sore throat accelerates healing and can be used along with conventional medication. Soda solution is an excellent antiseptic, the effect of which is multifaceted.
Doctors recommend starting rinsing at the first signs of deterioration in health. The sooner the patient starts treatment, the faster he will be able to overcome the infectious disease.

Indications baking soda for a sore throat
In what cases is it recommended to use soda for sore throat?
- If it is necessary to limit the development of infection in the throat.
- If it is necessary to alleviate the patient’s condition and stop the inflammatory reaction.
- If your throat hurts, or if it is scratchy, dry, or itchy.
- To stimulate rapid healing of the mucous membranes of the oropharynx.
- To improve expectoration, for expectorant action.
Soda is used for purulent tonsillitis to accelerate the transition of the acute stage of the inflammatory process to the subacute stage. Soda dissolves and removes pus, washes out purulent blockages, improves local blood circulation in the tonsils and trophism of inflamed tissues.
In general, soda can be used:
- for acute respiratory viral infections, flu;
- with inflammation of the tonsils (the same sore throat);
- for laryngitis (inflammation of the larynx);
- for pharyngitis (inflammation of the tissues of the pharynx).
Release form
Baking soda, or sodium bicarbonate, is available in powder form for external and internal use:
- 25 g each in dark glass jars;
- in 10 g packages (five or ten pieces per package);
- in cardboard boxes of 500 g.
Soda can also be called sodium bicarbonate or sodium bicarbonate, baking soda, or sodium bicarbonate. The substance is a salt of sodium and carbonic acid, and has the appearance of a white fine powder.
Typically, soda is used in the culinary and food industries, in construction and repair work, and in medicine.
In medical circles, the most common use of soda is local: soda liquid is ideal for rinsing, washing, and inhalation.
Pharmacodynamics
Soda is an antacid (anti-acid) preparation that neutralizes the action of acids. The decrease in acidity is usually rapid and temporary.
In addition, soda is often used for sore throats:
- has an expectorant effect;
- reduces the viscosity of sputum;
- increases the secretion of bronchial secretions.
Soda can irritate the receptors of the mucous membranes, causing unpleasant sensations in the form of burning and itching.
When absorbing large amounts of soda, alkalosis develops.
The anti-inflammatory principle of soda's effect on angina has not been fully studied. Presumably, a rapid bacteriostatic effect develops with subsequent long-term bactericidal action.
Pharmacokinetics
Soda in recommended concentrations is well accepted by inflamed mucous membranes and has an anti-inflammatory and external bactericidal effect.
When using soda locally for sore throat, its penetration into the serum is extremely low: swallowing about 4% of the total amount used is allowed.
After rinsing, about 30% of the soda remains on the oral mucosa and continues to act for half an hour.
Soda is used as a medicinal product for local use in the oral cavity. Systemic absorption and dispersion are practically absent. Minimal absorption does not allow measuring the drug content in plasma.
Soda does not accumulate in the body.
Dosing and administration
Rinsing with the addition of soda is not a complicated procedure at all. However, in order for it to be as effective as possible, the following tips can help:
- Water for making the soda solution is taken boiled or filtered, you can also use non-carbonated mineral water and melt water.
- The prepared soda solution should have a temperature of 37-38°C. If the solution is colder, the local immune defense will decrease. Hot water will excessively irritate the mucous membrane, which is already irritated by the inflammatory reaction.
- The soda solution for each rinsing session must be fresh - this is very important for the quality of the procedure.
- If you gargle with soda less than twice a day, there will be no positive result from such treatment. Ideally, use soda about seven times a day at equal time intervals.
- Most often, 200 ml of solution is used for one procedure. For treating children, this volume may be less - depending on the child's condition and how he or she tolerates such a procedure.
- The throat is gargled on exhalation, with a little effort. You can't strain the muscles too much - this will aggravate the disease. The duration of one exhalation is from thirty seconds to one minute (for children - if possible).
Gargling with soda for sore throat
There is nothing easier than making a soda mouthwash: just take a teaspoon of powdered soda and dissolve it in 200 ml of warm, clean water.
Soda creates an alkaline reaction in the throat, which makes the growth and development of pathogenic microflora impossible. Gargling provides a positive effect in case of sore throat or acute respiratory viral infections, and also prevents the possibility of secondary infection.
Treatment with soda rinses should be continued throughout the acute period of angina - on average, 3-7 days. This period largely depends on the severity of the disease.
Gargle only after eating, since after gargling you cannot eat or drink for half an hour so that the medicine can take effect.
Salt and soda for sore throat
Salt draws moisture out of cells – and this is where its healing effect lies, because salt affects microbial cells in particular. Liquid begins to “draw out” because the salt content in the external environment prevails over its content inside the cell. For human tissues, this process is practically safe, but the rate of development of microbes and viruses slows down significantly.
Sea salt is best for gargling, but if you don’t have it, you can use regular salt – table salt or “extra”. To prepare a medicinal solution for gargling, mix 1 teaspoon of salt and ½ teaspoon of baking soda in 200 ml of warm water. If you use regular salt, not sea salt, you can add 2 drops of alcohol iodine solution to the solution.
Salt, soda and iodine for sore throat help neutralize microbes and soothe irritated throat tissues, as well as eliminate swelling of the mucous membrane.
Milk with soda for sore throat
The use of milk with soda in folk medicine has long been known. Warmed milk with the addition of soda has a positive effect on the body weakened by illness, allowing you to quickly eliminate the main symptoms of a cold.
Milk and soda will save you from paroxysmal dry cough and will also have additional therapeutic effects:
- soothe a sore throat;
- will help to cough up phlegm;
- will alleviate painful sensations;
- will envelop the irritated mucous membrane.
Moderately warmed milk with the addition of soda also goes well with honey and a small amount of butter.
The simplest and most accessible recipe is considered to be this: stir half a teaspoon of baking soda in 200 ml of warm milk and drink it immediately after. This medicine works best if you drink it right before bed.
Proportions of soda for gargling with sore throat
To obtain a healing soda-based liquid, you need to dissolve one full teaspoon of soda powder in 200 ml of clean boiled water heated to a temperature of 37-38°C.
It is optimal to gargle 7 times a day. If you do it rarely, then such treatment will be ineffective. But gargling too often - more than 10 times a day - can cause overdrying of the mucous membrane, which will lead to worsening of unpleasant symptoms.
You should start rinsing at the slightest first signs of angina. If you start treatment on time, you can reduce the duration of the disease by 70%.
Soda for sore throat in children
Treating tonsils with soda for sore throat is a very effective and simple procedure with local action. It can be used for colds of any origin - viral, microbial or fungal.
Gargling with soda is permitted to be practiced for the treatment of children from the age of 3, that is, from the time when the child can perform certain actions under the supervision of an adult.
One of the positive aspects of using soda in children is that this method of treatment is practically free of contraindications, and local action largely guarantees the absence of side effects and unpleasant consequences.
However, when using soda to treat a child, one must not forget that any childhood illness, including tonsillitis, requires a pediatrician's consultation. It is strictly not recommended to independently select a treatment for a child and take any remedies, both traditional and folk.
Use baking soda for a sore throat during pregnancy
During pregnancy and breastfeeding, soda should be used with caution for sore throat. If soda is used for rinsing - that is, for local action, then such treatment does not pose a danger.
However, gargling with soda to treat upper respiratory tract diseases during pregnancy should be agreed upon with a doctor. If the doctor does not object to such treatment, and the woman herself does not suffer from individual hypersensitivity to soda, then you can start gargling with a weakly concentrated soda liquid.
Contraindications
Gargling with soda for sore throat should not be practiced only in case of serious damage to the mucous tissues in the throat and upper respiratory tract. For example, we are talking about burns or radiation damage to tissues.
If there are tumors in the mouth and nasopharynx, the use of soda is possible only after consultation with a doctor.
Other contraindications can be attributed to individual characteristics of the body. Thus, soda can cause a hypersensitivity reaction. Therefore, you need to stop treatment if the following symptoms appear:
- worsening of sore throat;
- the appearance of rashes and spots on the skin;
- the appearance of a runny nose and cough against the background of conjunctivitis, frequent sneezing.

Side effects baking soda for a sore throat
Soda for sore throat is usually well tolerated and has virtually no side effects. Undesirable symptoms may occur if the solution is diluted incorrectly (for example, a very high concentration of soda), if used too often (more than 10 times a day), and also if there is individual hypersensitivity to soda. We are talking about the following side effects:
- a tingling and burning sensation in the mouth and oropharynx;
- temporary impairment of taste bud sensitivity;
- irritation of the mucous membrane, itching, redness;
- throat irritation, cough;
- dryness of the oral mucosa.
All side effects are considered temporary and disappear after stopping the use of baking soda for rinsing.
Overdose
The use of a soda solution that is too concentrated, as well as performing the procedures too frequently, can cause an overdose in the form of side effects.
There is no specific antidote; symptomatic therapy is usually carried out simultaneously with the cessation of the use of soda.
Interactions with other drugs
The soda solution is compatible with most external medications used to treat sore throat:
- with chlorhexidine salts;
- with chloramphenicol, formaldehyde, zinc sulfate, silver nitrate;
- with alcohol and saline solutions.
When using soda while using acidic solutions, the effect of the latter will be neutralized.
Storage conditions
Baking soda powder should be stored in a dry and well-ventilated place, out of reach of children.
Despite the fact that the vast majority of medicinal products have their own expiration date, soda does not have such a limited period. However, the already prepared soda solution should not be stored: if the solution was not used immediately after preparation, it should be thrown away.
Reviews
Using soda for sore throat helps remove mucus from inflamed mucous membranes, promotes the healing of microdamage and stops the development of the inflammatory process at the initial stage of the disease.
Soda has a pronounced effect on any inflammatory reactions in the oropharynx: the soda solution disinfects and removes pus or mucus.
According to reviews, relief comes already on the second or third day after the start of treatment. However, for a quality effect, soda for sore throat should be used daily throughout the acute period, at equal time intervals, approximately seven times a day. One should not forget about the correct temperature of the solution prepared for rinsing. If the water is too hot or cool, the patient's condition will only worsen: the pain will become stronger, and the throat will literally "burn".
In addition, another rule is important: you should start rinsing as soon as possible. This directly affects how long the disease will last.
According to users, soda for sore throat has an effect not only when gargling. Often, doctors advise using soda for inhalations. In this case, the positive therapeutic effect of the soda solution is significantly increased. Inhalations are practiced for inflammatory diseases of the upper respiratory tract: during the procedure, the remedy gets not only into the throat, but also into the nasal cavity, trachea and bronchi.
During the entire period of treatment, it is necessary to adhere to all the doctor's recommendations, because it is known that angina is dangerous, first of all, due to its complications. It is better to use soda as an additional treatment method. Soda for angina is an excellent antiseptic that can significantly improve the patient's condition.
