I can only speak on the ear insufflation. My ears generally feel like they don't drain, and I really feel the inflammation during my period with migraines and earaches. I took a chance on the o3 treatment because I hit a breaking point. During treatment, I could tell it was changing something. Before I got into my car, I noticed my chronic jaw pain was non-existent. I've had tmjd for decades. I never connected my jaw pain to ear pain. It's been almost 2 weeks and I still feel great. Also, my menstrual migraines was less severe. I'll be visiting Wendy again! I'm hopeful this will continue to heal my ears. Any relief is better than no improvement. I really do believe in this healing tool. Thank you!

I read about o3 Apothecary through a mom’s group online so I made an appt. For ozone therapy for my clogged ears, runny nose, and dry cough. I went in with all of those symptoms and the next day, my ears were no longer clogged, nose clear, and my cough was minimal. HIGHLY recommend. 5 stars all the way around.

If you’ve never tried ozone therapy, then you need to get in to see Wendy ASAP! Ozone has transformed my life. It was the missing puzzle piece on my healing journey. Wendy is so kind and welcoming. She will give you all the information you need to feel confident and comfortable with ozone therapy. Next time you are feeling unwell get in for some ozone & you’ll be feeling better in no time.
