An acupuncturist takes a history along with a tongue and pulse reading to determine the "underlying pattern imbalance" such as Lung Qi deficiency, Lung Yin deficiency, etc. The principles of Chinese Medicine guide the acupuncturist in diagnosing and treating a condition, even when the cause is not obvious.
Acupuncture treats and balance your energy which stops the coughing. If it is from allergy as you said from air, acupuncture treatment also balance your immune system. so it will not go crazy when you face allergens.

Glad you asked!
If your chest x-ray is clear, the problem is most likely allergy related. There are several studies out showing acupuncture's effectiveness in the treatment of allergy. Speaking more generally, several studies have also pointed to acupuncture's ability to bring things down a notch when the immune system goes in to over drive.
To sort of skirt around the mumbo-jumbo issue - cough in acupuncture is considered a kind of 'rebellion' or 'counter-flow'. The type and quality of the cough (loud, soft / dry or with expectoration) tells us what is rebelling or counter-flowing. That information helps us to arrive at a treatment.
I've treated a lot of persistent cough and allergy patients. I typically get good results unless there is something else going on (like lung infection, which you've already ruled out).

On a more generic answer, the acupuncture can help because it can open the muscular tightness that is inhibiting deeper breaths that the cough is forcing out. The acupuncture can help replenish fluid circulation thus moistening the lungs and relieving the cough. The acupuncture can "pull out" the heat/cold or dry factors. Additional treatment strategies could include dietary suggestions (like eating pears) or using cupping treatment, gua sha treatment, etc.
When western medicine sees nothing, we usually have the tools to help because we see differently.
According to TCM (Traditional Chinese Medicine), cough can be caused by a variety of issues or conditions related to environmental, physical or emotional imbalances. There are several questions an Acupuncturist Physician may ask related to your cough and lifestyle. Such as, is your cough productive or dry, the color of mucus, prevalence of the cough, the
time of day and your emotional state in order to get to the root cause of your cough. Acupuncture can definitely help your loud cough. Find a licensed Acupuncture Physician in your area to get an appropriate evaluation and treatments that may resolve your cough.
Sincerely, yours in health!!
