Bests & Worsts Reviews from Amazon

The National Institute of Health has published that the outer part of the leaf can be toxic to the liver, that's why many products only offer the "filet" or inner part of the leaf. After receiving my shipment I looked on the bottle for info on filtering out the toxic elements and didn't see it. I asked their customer support and just got a link to their website that gave zero information regarding my specific question. The e-mail stated if I had further questions to just respond. When I followed up I was ignored. I strongly suspect they have a process by which they remove the potentially toxic part of the plant, but, without any real proof of that on their packaging and just vague statements about "complex grinding and filtering procedures" and a "proprietary process" on their website I guess I'd rather be safe than sorry and keep my liver healthy. It's really too bad they can't just say that the toxic parts aren't in the product you receive!
