waterspritehi, Thank you so much for so many suggestions to try. I have considered colloidal silver. I have to try one thing at a time....sensitive Nellie that I am! I am going into my 9th week of getting over asthmatic bronchitis, pneumonia & sinus infection. This humidity this summer has been the hardest summer of my life with asthma. I personally believe due to my sensitivity to allergens that the fires across our land with the debris got all of this started and the humidity escalated it. I use alkalol and it is wonderful....it can be too drying so I don't use it all the time. I have been on a nebulizer for 3 weeks with Albuterol 2.5 mg and it is helping greatly. I am trying to boot up my immune system which helps with sinus issues & allergies. Someone told me about Jade Leaf Organic Matcha Tea (it's on Amazon and is about $10). I add 1/2 teaspoon to my morning protein shake. I am also irrigating my sinuses daily with NeilMed sinus rinse....that is helping. The netti pot backs up in my eustachian tubes and this one doesn't. I also added Quercetin Phytosome by Thorne daily. Please check with your doctor before trying any of these. One thing at a time.....One day at a time. God Bless you and thank you for your valuable input.
