If it’s in the sinuses t should clear it up fast. Not too great for chest unless it’s moving to the chest from sinuses.
If the doctor saying allergies as seasonal then that’s what they will be, seasonal not 24/7. Now they’re spraying at night, people should get heppa air filters maybe with uv lights.
It’s good for many things including antibiotic and anti cancer and more. Check for any drug interactions or side effects. Probably good to take vita B supplements and you’ll probably know if you are irritable or other symptoms.

If more than just sinus you can check out other remedies or find your own specified remedies with the symptoms at ABC homeopathy for your wife but best if she does it.
