Oil of Oregano. One drop outside each nostril, to be absorbed through the skin, the balance of the dropper under the tongue. Hold there as long as possible before swallowing down w/ water. Taste dissipates quickly. Follow this routine 2x daily. Preventatively as well. Pricey, well worth it. I've not had a cold, congestion, etc in the 3+ years since I started this routine.
I'm glad to know that the strips work well. I find Grapefruit Seed Extract and Oil of Oregano to be wonderful preventatives. And, so far, that has worked to keep me unplugged this winter (I have always struggled with sinus issues). But I took notes on all suggestions given in case of need. Thank you for your post. I'm glad you found some relief, and I hope you feel well very soon.
