Dr. Murray Grossan's book entitled The Whole Body Approach to Allergy and Sinus Health is an excellent read. This publication offers numerous up-to-date natural strategies for good nasal health.
The recommended treatments are 1) inexpensive 2) easy to implement and 3) effective. Evidence-based treatments from nasal irrigation to proper diet to relaxation techniques are covered - and at length.
As an empty nose syndrome (ENS) sufferer, for instance, I find the recommended breathing techniques while doing biofeedback in the comfort of my home to be very practical; and the best part is it does not cost me a penny! A very sympathetic supporter of our needs, with his own practice offering implants taken from ear cartilage for ENS patients, Dr. Grossan offers a discussion of ENS on page 228. His conversational and easy-to-understand style of writing make this book an enjoyable read. Check it out.
