Sore throat is one of the most common discomforts during the cold season, but it can also occur in summer due to exposure to air conditioning or consumption of cold drinks. In the face of this condition, many people turn to natural remedies, and gargling with salt water and medicinal herbs is one of the oldest and most accessible home remedies. But how effective is this remedy in reality? What do studies say? How is it prepared and used correctly?
Benefits of Gargling with Salt Water and Herbs
1. Anti-inflammatory and Local Soothing Effect
Salt has an osmotic effect on the throat mucosa, which means it helps draw fluids out of inflamed tissues, thereby reducing local swelling. This leads to decreased tension in the pharynx and associated pain. Additionally, the saline solution creates an unfavorable environment for bacteria. By soothing irritation, salt also helps reduce the sensation of scratchiness in the throat. The effect is almost immediate and can last for several hours after use.
2. Removal of Secretions and Pathogens
Gargling helps mechanically eliminate mucus, bacteria, and viruses from the pharyngeal mucosa. Through this process, the local microbial load temporarily decreases, which can lead to symptom relief. Although it is not a curative method, it reduces the risk of superinfections. Furthermore, gargling with salt water is effective in cases of mild pharyngitis and viral forms without complications. It is a very useful method in complementing medication treatment if necessary.
3. Supporting Mucosal Regeneration
When medicinal herbs are added, the soothing and regenerative effect significantly increases. Herbs such as marshmallow, mallow, or calendula contain mucilage that forms a protective layer on the irritated mucosa. This layer reduces the sensation of burning and helps repair damaged tissues. Repeating gargling with herbal infusions can accelerate the healing process. It is important that the liquid used is warm, not hot, to avoid aggravating irritation.
4. Antimicrobial Role (Especially in Combinations with Herbs)
Certain herbs used in gargling, such as thyme, sage, and mint, have proven antibacterial properties. These can help reduce the growth of bacteria in the throat and oral cavity. Thyme contains thymol, a natural compound with antiseptic effects, while sage contains flavonoids and volatile oils with antifungal and antibacterial action. In combination with salt, the antiseptic effect is enhanced. It is an effective option in cases of mild infections but does not replace antibiotic treatment when prescribed.
5. Reducing Discomfort When Swallowing
Many patients with sore throats experience difficulties swallowing due to swelling and irritation. Gargling with salt water, especially in combination with marshmallow or mallow, soothes the mucosa and reduces pain when swallowing. This has a major impact on the quality of life, especially during meals. An additional effect is the reduction of the need to use classic anti-inflammatories. Moreover, it can prevent complications such as prolonged irritation or hoarseness.
Scientific Studies: What Do Researchers Say?
1. Study Published by Mayo Clinic
According to Mayo Clinic, gargling with salt water is one of the most recommended methods for soothing sore throat pain, especially in the acute phase. The osmotic effect of salt reduces inflammation and cleans the area of pathogens. It does not treat the cause of the illness but helps alleviate symptoms. Doctors note that this method is safe and can be repeated several times a day. It is especially useful for viral infections, where antibiotics have no effect. Additionally, gargling is considered beneficial in cases of mild hoarseness or irritation caused by dry air. The study also showed that patients who used this method reported a faster decrease in discomfort. Gargling is non-invasive and does not produce adverse reactions if prepared correctly. It is an effective complementary remedy, especially in the first days of infection. It is recommended alongside hydration and rest.
2. Study Published in Journal of Family Practice (2020)
A study conducted on 338 individuals evaluated the effectiveness of gargling with salt water and herbs in cases of viral pharyngitis. Participants were divided into three groups: one group used plain water, one with salt water, and another with salt water plus sage extract. After 3 days, the group that used the herbal solution showed a significant reduction in pain and redness. According to the authors, the combined action of salt and herbs has synergistic effects, both antiseptic and soothing. Additionally, the level of comfort when swallowing increased significantly. The effectiveness lasted for at least 4 hours after gargling. Researchers emphasized that this method is inexpensive, safe, and easy to apply. No notable adverse effects were observed. The conclusion was that it is an effective remedy for mild to moderate symptoms. The recommendation was for this method to be included in self-care guidelines for colds.
