While there are some skeptics out there, I can 100% back the substance. It's a massively strong antiinflammatory, antispasmotic, and antimicrobial that is 100% natural in origin and is impossible for your bugs to develope resistance to (regardless what some uninformed medical professionals might feel, trust me, i've done my research while nearly all of them have not, the information is out there for you if you want to look into it).
The antiinflamatory properties alone are reason enough to take the substance, and more so directly introduce it into your lungs for better reactivity, but taking it sublingually helps a ton compared to not taking it in any way at all. Oregano oil is not the only wonder substance out there that helps us, it's just one of them, and granted it's extremely powerful for many many many chronic health problems (like CF).
Eventually with time, I will be found to be 100% correct in the use of oregano oil based supplements to treat CF, I don't care if i'm long dead, but it will eventually come to the surface and be embraced, and I will be grinning in my grave <img src="i/expressions/face-icon-small-smile.gif" border="0">
The use of the substance for me, has resulted in nothing short of a miracle, on many levels. I'm now able to fully work, and put my body through torture only 20 something year old healthy non CF guys could do to themselves. The substance holds zero concern to our tissue in a negative aspect, but all positive. It reaks havok on our bacteria, and repairs our cells, and helps to stop the never ending inflamation/infection chain our body does to us.
I could go on all day, but i'm VERY happy another CF is enjoying profound positive results on the substance. Of course time will tell with regards to it's use and each individual, but i'm going on coming up on a year on the substance, and inhaling it for a good part of that time...My bleeds are basically non existant now, and I fell like i'm 16 again (with the exception of the beer gut lol).
Now, as for what to watch for...There is nothing that is overtly bad per say. After using the substance a few times, due to it massively killing off bacteria, yeast, fungus, and possibly even viruses, you will have their death toxin in yoru system and feel extremely tired for the first several days, after which you will feel normal again and really start to feel awesome on the stuff.
Aside from that, not every person tolerates it well. If you start to feel worse that before the use, in any strong way, for any drawn out period of time, or have obvious bad reactions to the substance, stop using it. I have a sneaking suspicion several of the CF's who started to use the substance, especially inhalation, stopped doing so due to anxiety in general, and psychosomatia drove some of their symptoms, due to how they view their doctors, and the paranoia of altering their treatment regimen.
Keep us informed on how you do on it, any data, is good data. I'm still kicking as* and taking names, and several other CF's have reported when they stop taking/inhaling the substance, they feel "like crap" soon afterwards. The substance won't obviously cure CF, but it will help drastically reduce our CF symptoms.
