Respiratory health often seems to be the most vulnerable part of the body, and at the slightest sign of the flu or a common cold, the throat begins to hurt, the sinuses get congested and the urge to cough begins to rise up from the chest. These three common symptoms can be painful, inconvenient and long-lasting if you fail to treat them properly. Using essential oils for sore throat, cough and congestion symptoms is an excellent option for rapid relief.
A sore throat typically occurs when you have a viral infection, which can inflame the mucous membranes in the throat and cause those tissues to become irritated. Nasal congestion occurs for a similar reason, when the nasal tissues become irritated and the mucosal membranes begin releasing extra mucus in response, causing a stuffy nose and blocked sinuses. When that excess mucus runs down into the throat or is sniffed and swallowed, it can take up residence in the lungs, along with other fluids and phlegm. This chest congestion can cause tightness, pain or discomfort, which leads to coughing, the violent, hacking response of the lungs and chest to expel excess mucus, or in response to irritation in the throat.
Clearly, all of these symptoms are closely linked, but with the proper use and blends of essential oil for sore throat, cough and congestion, you can quickly soothe this inflammation and get on the road to recovery.
