Cough

A cough is one of the body’s most important protective reflexes, clearing the airways of irritants, mucus, and foreign particles. Most coughs are acute — tied to a cold, bronchitis, or other short-term infection — and resolve within a few weeks. A cough becomes chronic when it lasts eight weeks or longer, and chronic cough is a distinct problem with its own set of causes: postnasal drip, asthma, acid reflux, and airway sensitivity among the most common. Because a lingering cough can occasionally point to something more serious, identifying the cause through a medical evaluation is an essential first step.

A cough can take several forms, each offering clues about the cause:

• A dry, tickly cough or a wet, productive one
• A cough worse at night or when lying down (often reflux- or drip-related)
• A cough triggered by cold air, exercise, or allergens (often airway-related)
• Throat clearing and a sensation of a lump or tickle
• A cough that lingers long after a cold or infection has passed

Common causes include viral infections, postnasal drip from allergies or sinus issues, asthma, acid reflux, and airway irritation. Smoking and certain blood-pressure medications can also provoke a chronic cough. Because the causes are so varied, effective relief usually depends on addressing the specific underlying driver.

In Chinese medicine, the cough is intimately connected to the Lung, whose job is to govern Qi and keep it descending smoothly. A cough is seen as Lung Qi rebelling upward instead of flowing down — whether pushed by an external invasion of wind, cold, or heat, or by internal factors like phlegm, dryness, or a deficiency of the Lung itself. A dry, hacking cough is understood differently from a wet, phlegmy one, and a cough rooted in weakness differently from one driven by heat. Treatment aims to restore the Lung’s downward flow and address whatever is disrupting it. Dr. Willcox identifies the specific pattern before treating.

Acupuncture for cough is thought to work by calming the cough reflex and airway sensitivity, easing inflammation and muscle tension around the airways, helping to resolve phlegm, and supporting the immune and nervous systems. Because chronic cough often involves a heightened, hypersensitive cough reflex, acupuncture’s calming effect on the nervous system may be particularly relevant.

The research here is reasonably encouraging. A 2025 systematic review and meta-analysis of thirty randomized trials found that acupuncture-related therapy, added to conventional treatment, significantly improved cough severity and cough-related quality of life in people with chronic cough, with a moderate certainty of evidence and no increase in adverse events. In practice, acupuncture is best used as a complement to conventional care while the underlying cause is identified and addressed.

At Acupuncture Zen, cough is often addressed with acupuncture and, where appropriate, Chinese herbal medicine — a long tradition for respiratory complaints — always alongside a physician’s care.

A first visit begins with a detailed conversation about the cough — how long it has lasted, whether it is dry or productive, what triggers or eases it, and any diagnosis already made. Treatment involves fine needles at points chosen to calm the cough and support the lungs, sometimes with gentle warming, followed by a period of rest. For a lingering cough, treatment usually consists of a short series of sessions. Dr. Willcox coordinates with a patient’s physician and will encourage medical evaluation for any cough that is severe, prolonged, or accompanied by warning signs.
