If you google Noni Juice you will come up with quite a few articles on it.I started using it here for my pluckers about 3 mths agao.I use the Tahititi Trader kind that has a few other juices in it. I saw improvement in 3 of 5 of my pluckers.I ran out once for a few days and they plucked the new feathers they let grow in. I started back up and they started letting them grow again. Then I switched to just 100% Noni and they started plucking the feathers again.So my thought it is it is either the combo of the juices or one of the others that helps.I want to try each of the juices individually,but haven't got that far yet.
