The nose has a vast network of blood vessels with valves that open and close. When the nose is stimulated by any irritant, the nervous system is also stimulated. This causes valves to open, which results in more blood entering the nose. This causes swelling in your nasal passages, which makes it difficult to breathe. Nasal congestion can be caused by anything that irritates or inflames the nasal tissues. Colds, flu or sinusitis, allergies and various irritants may all cause a runny nose. Some people have a chronically runny nose for no apparent reason, a condition called nonallergic rhinitis or vasomotor rhinitis (VMR). Natural Congestion Relief product will depend on the cause of the inflammation.
