Lingering Cough

Recently, a colleague of mine asked me about the best acupuncture points for treating post-viral cough. I saw an opportunity to share insights through this blog post.

 

Persistent cough frequently follows an upper respiratory (viral) infection. While initially serving as a protective mechanism during the acute phase of infection, once the illness subsides, coughing does little good but irritates the lungs and, quite frankly, the people around.

 

Inflammation of the airways and excess mucus production can directly stimulate cough receptors, leaving them in a hypersensitive state. Additionally, unrelenting coughing can be perpetuated by the secretions draining from the nasopharynx (postnasal drip) or acid reflux from the esophagus.

 

 

Common Cough Remedies

Treating lingering cough requires quieting inflammation in the respiratory mucosa and modulating the nervous system.

 

Symptomatic treatment typically involves oral antihistamines (to reduce postnasal drip), benzonatate (vagal anesthesia), dextromethorphan (centrally acting antitussive), inhaled ipratropium bromide (anticholinergic), and/or steroid (anti-inflammatory). Some physicians may even resort to a brief course of oral corticosteroids.


 

Acupuncture – Natural Option

An ever-increasing number of folks are turning to acupuncture.

 

Acupuncture, an ancient healing art rooted in Traditional Chinese Medicine (TCM), involves the insertion of thin needles into specific points on the body to stimulate energy pathways, or meridians. By restoring balance and harmony within the body, acupuncture aims to enhance the body's natural healing mechanisms.

 

According to TCM, a persistent post-infectious cough is associated with deficient Yin “Fluids” burned out during the active infection.

 

By regulating the flow of Qi, or vital energy, acupuncture helps to strengthen the lungs, boost the immune system, and promote respiratory function. In addition to acupuncture, cupping, moxibustion, and herbal medicine may also be incorporated into the treatment plan.

 

Research studies have provided evidence supporting the efficacy of acupuncture in treating respiratory conditions. Acupuncture has been shown to have anti-inflammatory and immunomodulatory effects, which can be particularly beneficial in the context of post-viral cough.

The Bottom Line

Don’t reach for antibiotics … yet! First, try simple over-the-counter cough remedies. Honey (the real one) works fine too. Maybe even ask your doctor for Medrol 6-day Dosepak. Or, if you are a holistically minded person, visit Point of Cure Acupuncture and Electromedicine for a gentle yet powerful healing session.
