Post-Flu Recovery and Long-Term Wellness: Clearing Residual Phlegm with TCM
In January 2025, Calgary experienced a significant uptick in respiratory illnesses, including influenza, respiratory syncytial virus (RSV), and COVID-19, with influenza being the most prevalent. Flu cases, particularly the influenza A (H1N1) strain, were notably high during this period. Many patients have experienced lingering symptoms such as persistent coughing, excessive phlegm, and fatigue. While it’s common for these symptoms to improve over time, they can sometimes develop into chronic conditions, potentially weakening the body's organ systems.
The Difference Between Flu, RSV, and COVID-19
While flu, RSV, and COVID-19 all affect the respiratory system, they are caused by different viruses and require distinct approaches for treatment and recovery:
Flu (Influenza): Caused by influenza viruses, this illness is often characterized by fever, body aches, chills, extreme fatigue, sore throat, and cough. The flu is more likely to cause widespread systemic symptoms like muscle aches, fatigue, and high fever. It can also lead to secondary infections, including pneumonia.
RSV (Respiratory Syncytial Virus): RSV affects primarily the lungs and causes bronchiolitis or pneumonia, particularly in infants, elderly adults, and people with weakened immune systems. Symptoms can include wheezing, difficulty breathing, a severe cough, and nasal congestion. RSV is often milder than the flu but can be dangerous for vulnerable populations.
COVID-19: Caused by the SARS-CoV-2 virus, COVID-19 has symptoms similar to the flu but can include loss of taste or smell, gastrointestinal issues (like diarrhea), and more severe complications, including difficulty breathing, pneumonia, and multi-organ failure. COVID-19 also tends to have a much higher rate of transmission.
Though these diseases share some overlapping symptoms, they each require specific TCM diagnostic approaches for treatment.
Signs and Symptoms of Post-Flu and the Importance of Treating These During Post-Flu Care
Even after the acute symptoms of flu, RSV, or COVID-19 subside, many individuals experience lingering post-flu symptoms. These include:
Persistent cough: Often accompanied by phlegm, this can remain even after the fever and body aches have passed.
Fatigue: A feeling of tiredness or lack of energy that doesn’t resolve easily with rest.
Shortness of breath: Difficulty breathing or a sensation of tightness in the chest, often from phlegm buildup in the lungs.
Muscle or joint pain: Lingering aches or stiffness in the body, particularly in the back, neck, or legs.
Headaches: Some individuals experience tension or pressure in their head long after the flu has passed.
Digestive disturbances: Nausea, indigestion, or a lack of appetite due to weakened digestion from the flu or COVID-19.
Sleep disturbances: Difficulty sleeping or disturbed sleep patterns, often exacerbated by lingering flu symptoms or post-viral fatigue.
Decreased immunity: Higher susceptibility to colds or other illnesses due to a weakened immune system after the flu, RSV, or COVID-19.
The Importance of Post-Flu Care
Addressing these lingering symptoms is essential to prevent chronic conditions. Without proper treatment, they can lead to:
Chronic respiratory conditions: If the phlegm and dampness are not cleared, they may turn into long-term lung issues or even chronic bronchitis.
Weakened immunity: A weakened immune system can leave the body vulnerable to future illnesses.
Digestive problems: Lingering symptoms can affect the digestion and spleen, leading to bloating, poor appetite, or nausea.
Traditional Chinese Medicine plays a crucial role in clearing residual phlegm, strengthening the immune system, and restoring overall balance to the body.
The Role of TCM in Post-Flu Recovery
TCM helps to resolve residual dampness and clear lingering phlegm, both of which are common after flu, RSV, and COVID-19. TCM treatments, such as acupuncture and herbal medicine, focus on:
Expelling Remaining Pathogens: At the start of recovery, herbs expel any remaining pathogens from the body. As recovery progresses, formulas evolve to address phlegm and dampness, which are common in all three illnesses.
Clearing Phlegm and Dampness: Herbs like Ban Xia (半夏) and Chen Pi (陈皮) help clear mucus, improve lung function, and reduce the risk of a lingering cough.
Strengthening Immunity: To help prevent future illness, TCM uses Qi-boosting herbs like Huang Qi (黄芪) and Bai Zhu (白术) to strengthen the lungs and spleen, supporting the immune system.
Preventing Chronic Conditions: If residual dampness and phlegm are not addressed, they may develop into chronic respiratory conditions or affect digestion. Acupuncture and herbal medicine help restore balance, preventing these complications.
Acupuncture for Post-Flu Recovery
Acupuncture enhances the body's ability to clear phlegm, boost immune function, and restore energy. Points like LU5 (尺泽) and ST40 (丰隆) help eliminate phlegm, while LI4 (合谷) and ST36 (足三里) strengthen immunity and promote recovery.
Additional Lifestyle Recommendations
Herbal Teas for Lung Health: Drink teas made with roasted Jie Geng (桔梗) to help clear phlegm and support lung function. Xing Ren (杏仁) helps relieve coughing, while Sang Ye (桑叶) cools heat in the lungs.
Hydration & Warm Foods: Drinking warm ginger and honey teas helps expel mucus, keeping the respiratory tract clear.
Breathing Exercises: Gentle Qi Gong or deep breathing exercises can help support lung function and aid in phlegm clearance.
Avoiding Dairy and Greasy Foods: These foods can contribute to excess dampness and worsen lingering symptoms.
Conclusion: Prioritizing Post-Flu Recovery for Long-Term Health
With flu, RSV, and COVID-19 cases still prevalent in Calgary, it's essential to address lingering symptoms post-recovery. Incorporating TCM treatments such as acupuncture and herbal medicine can help clear phlegm, strengthen the immune system, and promote long-term wellness. If you're recovering from the flu or other respiratory illnesses, seek professional TCM care to ensure your full recovery and prevent future complications.
By addressing residual phlegm and strengthening the body’s natural defenses, TCM offers a comprehensive, holistic approach to post-illness recovery, empowering you to achieve long-term health.
