I have asthma, which is usually allergy induced, I found this blend in a health food store WHILE having an asthma attack, I cannot use an inhaler and am always looking for relief sources, especially natural ones due to being allergic to fragrances and so, SO MANY other things. I used the tester to this and FELT A DIFFERENCE like instantly! I'm not saying the attack instantly ended, but another 5 or 10 minutes later I actually could breathe and focus again, I obviously purchased the product and have used it since, I've gone whole days with classic allergy symptoms before finding this, and this actually helped THANKS SO MUCH! OMG!
