I am not a doctor, nutritionist, or someone related to the industry. However, I am a combat veteran with severe allergies, slight copd, and other health issues. The military docs sent me to an "allergist" whom diagnosed me with allergies to just about everything. Great. I got on the weekly shots deal and paid a steep co-pay for the meds. I did this for about 5 weeks and quit. Seemed like a sham...clinic was in bed with some drug company or something. So, I quit. I started taking these Oregano Oil caps...been on them for about 6 months. No more breathing issues when going outside, no more "air" sensitivity, and my allergies symptoms overall are (guesstimate) about 90% cured. I still have an occasional (I mean rarely) allergic reaction to something that is really strong. But, overall...I feel this product has helped me considerably. Weird. When I was stationed in Italy in the early 90s...I had severe bronchitis and was sick for days. My Italian landlord made me "some kind" of soup. To this day, I don't know what was in it...prob Oregano, basil, bay leaves, and other greens. Within a day, I was almost cleared up
