I've been using these pills from Integrative Therapeutics for over a year, and I've probably bought six or seven bottles so far. I sometimes buy them directly from my doctor's office, and other times from Amazon. They are always a mustard yellow and soft to squeeze. This last order I received contains a bottle that looks the same, but the pills are brown and rigid. I cut one open to see if they smell the same, and they do smell like I remember, but I am using them as a treatment protocol and I wonder if they are expired (the bottle says they are not) and if they will work as well as the pills I usually get. I am hesitant to order these off Amazon again and will probably have to get them from my doctor from now on.I suffer from chronic gut yeast overgrowth after years of antibiotics for sinus issues. This formulation is predominately oregano and thyme oil and is an effective anti fungal without all the harsh side effects from prescription anti fungal drugs. The pills are small and easy to swallow. The natural oils have broad spectrum beneficial properties so help your immune system as a whole. Integrative Theraputics have high production standards and effective formulations - this is just one of their products I have used and continued to re-order.I bought this for my 75 year old mother who was experiencing frequent ear problems and had a consistently white coated tongue. After a week of taking this she was excited to see a pink tongue. Time will tell if thecear issues will resolve. She prefers to take it with food as she seems to taste the oregano if taken on an empty stomach.I was diagnosed with intestinal yeast when I was 28. Everyone has candida just for some people it gets out of hand. This has really helped me - stomach is flatter and I find I’m not as sensitive to my cheat foods as I was beforeThis is pretty strong stuff and it could damage your gut. I recommend using it out the capsule mixed with water and then rinse your mouth out well to protect the enamel on your teeth. I also recommend using it with a meal and other antifungals. Be careful you do not hurt yourself and be aware how your body is tolerating. It may be good to pace yourself to your tolerance.It’s doing everything it says it does. My doctor recommended these.Life long requirement for chronic bacterial infection. Resolved inflammation better than any NSAID without ruining the stomach.I have tried almost everything out there and this is one of the few products that controlled yeast infections and Candida overgrowth. Yes, it's expensive - but I'm happy to pay that cost to prevent uncomfortable yeast overgrowth. Note, it takes a good week or so for the product to start alleviating symptoms.Absolutely excellent. A bit pricey but without a doubt extremely effective.
