It can. I have had many patients come in for treatment while having an attack. They stopped wheezing, their breathing relaxed, the tightness in their chest disappeared. But there is a better and more convenient way. Don’t wait till you are having an attack—be proactive. A series of acupuncture treatments over time should reduce the severity and frequency of attacks.
The key is to change the response of the body to stressors—whether environmental or emotional—over a period of a couple of months. This is done by receiving regular treatments—say, once or twice per week.
To summarize—Regular treatments over a period of time appear to retrain the physiology so it has a more relaxed response to stressors that would normally provoke an attack. Acupuncture coaxes the body into a higher state of health.
