Hi Bill: I am really glad I talked to you that day and tried HP inhalation. It has brought my Ragweed Allergy so much under control. I just pumped HP 4-5 times in my mouth and it literally stopped the sneezing and post nasal drip. You are my inspiration. Now I think I can say something is WORKING against my allergies, when even the famous Vitamin C did not work. thankyou. God bless you and your family.
