Possible Lung Qi / qi (vital energy) deficiency?

You would get the best results by going to a local acupuncturist or herbalist to get an appropriate diagnosis. For choosing herbal formula it is not as simple as matching a particular symptom to a specific formula. In clinical practice single herbs like huang jing are almost never used because it takes combinations of herbs working together to address various underlying imbalances.

In your case your symptom of anxiety could be related to the mucus/wheezing if you’re underlying pattern is something like phlegm misting the mind. Or the anxiety could be due to some form of yin deficiency while the wheezing\mucus could be due to dryness. Just based on what you said here isn’t enough to determine the correct pattern (which is akin to a diagnosis). This is why seeing and being diagnosed by a licensed practitioner is important.
