Oregano Oil. We bought the stuff from North American Herb and Spice that has cumin and sage in it called Oregacyn. Also have recently started taking Apple Cider Vinegar. Oregacyn completely cures sinus infections and completely reversed my son's asthma. ACV helps eradicate sinus stuffiness and itchy patches on the skin. I wanted to recommend a couple of other books that are definitely worth reading in your "Worth Reading" section: 1. The Cure is in the Cupboard by Cass Ingram. I love this book it is about oregano and it helped my son so much with his asthma. 2. The Fungus Link by Doug Kaufmann, I love his show-I am a faithful watcher every week day. I truly believe fungus is among us! 3. Beating Cancer with Nutrition by Patrick Quillin. This book was a wonderful guide to help my mother when she was battling lung cancer. The book outlines which foods can help our body heal from cancer during chemotherapy and radiation treatments, as well as which foods can help stave off chemo sickness during treatment. I love the nutritional aspect of improving the immune system. Thanks for your time. Love the website-I think I could become an addict to it!
