Put a few drops of Oil of Oregano in a pan with water and put a towel over your head and breathe in the steam, not too close.
Might help.
God Bless
MQD, this method is quite effective. However, it can be harsh. You will likely cough. I get the water to barely steaming, put the drops in (just a couple), and then huff it like a skid row bum huffs paint.
In another vein, I’ve made a chlorine dioxide solution (CDS) in a nasal sprayer. Normally I’d use a homemade Xlear (xylitol) spray, but I was out of xylitol. The diluted CDS spray seems to do as good a job as Xlear and probably better. While Xlear is an excellent prophylactic, the CDS can be a prophylactic AND a remedy. We call it “Snoot”.
