If you're getting the noni straight off the trees there, apparently it's done by the people in India or in the area where you live, right? I mean, the noni I've bought came from Hawaii and the people who import it went there and talked to the locals and found they used it for all sorts of things.
Have you tried magnesium for cramps?
Yes, detoxing symptoms can be varied and overwhelming not to mention making you feel horrible. If it doesn't pass within a week or so, two at the most, I'd say it's not detox, but the product. Is this your first time with noni? Perhaps you have an allergic reaction? Perhaps it's something else. Just trying to consider all the angles here. That's just based on my experiences. Perhaps others will share more?
