If you have asthma for real. Do not buy any of these crap noni or african voodoo or whatever.
Listen to the md that posted in here. Go to a real doctor and begin to work with them to find the right treatment.
Do a search on noni and tell me what you find, the only research that is out there to support its usefulness will be funded and completed by the people that make the product. The only testimonials you will find will be those of "miracle patients" that either do not exsist or now sell the product so of course they have unreal results.
You will be likly to see that the actual studies that have been done by outside sources will show that most of these jucies are less than 4% noni and then it is so super-processed that its actual chemical structure does not even reflect that of the real noni fruit. Which by the way is also a terrible tasting fruit that has to be processed so that it will taste at least palletable.
Do not buy garbage and expect it to become a good alternative. This problem can be leathal and only an md or do can help to ensure your safety when having an attack.
