Sniffling and Stuffy: What Is the Solution for Chronic Rhinitis Worsened by Phlegm-Fluid?

How can the Donguibogam concept of phlegm-fluid be interpreted through modern medicine? I view phlegm-fluid as a concept encompassing not just visible phlegm, but also a chronic low-grade inflammation state and fluid imbalance widespread throughout the body. Modern medicine defines rhinitis as an inflammatory response of the nasal mucosa. It can be a hypersensitivity reaction to an allergen, or it may arise from non-allergic factors such as temperature shifts, vehicle exhaust, or stress. The insight from the Donguibogam that phlegm-fluid worsens rhinitis suggests a deep connection between rhinitis and overall systemic health, extending beyond localized inflammation. First, phlegm-fluid signifies fluid retention inside the body. In modern medical terms, this correlates with impaired lymphatic circulation, excessive accumulation of extracellular fluid, or mucus hypersecretion. The nasal discharge in rhinitis patients is not plain water; it is a blend of protein-rich fluid exuded from blood vessels due to an inflammatory response, along with immune cells and mucus. If overall body fluid metabolism is sluggish, these mucous secretions become stickier and harder to clear, worsening nasal congestion and postnasal drip. This aligns directly with the Donguibogam teaching that accumulated phlegm-fluid becomes turbid and sticky. Furthermore, phlegm-fluid is closely linked to weakened function of the digestive system, particularly the spleen and stomach. Modern medicine places great importance on the connection between gut health and the immune system. The gut is a central immune organ where roughly 70 to 80 percent of the body's immune cells reside. If the intestinal mucosa becomes compromised due to poor dietary habits or severe stress—as seen in leaky gut syndrome—undigested food debris and toxins can enter the bloodstream and trigger a systemic inflammatory response. This systemic inflammatory response fuels hypersensitivity reactions in the nasal mucosa, aggravating rhinitis symptoms. Diets dominated by refined sugars and processed foods foster the proliferation of harmful bacteria in the gut and provoke inflammation, echoing the Donguibogam principle of dampness accumulating in the spleen and stomach. Let us also look at this from a neurological perspective. A chronic inflammatory state causes an autonomic nervous system imbalance. When the sympathetic nerve becomes excessively activated, blood vessels constrict and mucus secretion may temporarily decrease; however, a subsequent rebound excitation of the parasympathetic nerve can worsen runny nose and nasal congestion. Stress is a major factor that disrupts autonomic nervous system balance, and it exerts a profound effect on our immune response. In other words, stress worsening rhinitis is not merely a psychological issue, but a physiological reaction intimately involving the neuroendocrine-immune network. The Donguibogam concept of phlegm-fluid provides brilliant insight uniting these complex modern medical ideas. Chronic rhinitis is not just a nasal issue; it is a signal that emerges when the entire system—including body fluid metabolism, digestive health, immunomodulation, and the stress response—is out of harmony. For those struggling with runny noses and nasal congestion, rather than relying solely on temporary relief medications, efforts to improve the body's internal environment are essential. Wholesome eating habits, regular routines, stress management, and activities that support fluid circulation will greatly help reduce phlegm-fluid and relieve rhinitis. Our bodies are interconnected.
