Is it safe for me to take LarreaRx™?

LarreaRx™ products contain a patented, highly purified extract of Larrea tridentat, not the crude, unprocessed "chaparral" herb that many other products contain. We employ patented technologies that involve processing of Larrea tridentata extracts with natural, non-toxic antioxidants, such as ascorbic acid (vitamin C), to reduce NDGA quinone and other oxidative compounds than might be present in some other Larrea tridentata extracts.
Formulations of LarreaRx's™ patented Larrea extract were the subject of an independent scientific study conducted at the University of Arizona College of Medicine. This data shows that Larrea extract produced according to the patented processing methods is no more toxic to liver tissue than other generally recognized as safe (GRAS) food substances such as cinnamon oil and clove oil.

Larrea tridentata is an official homeopathic drug in the United States and Europe and has a decades-long history of safe use as such. Homeopathic Larrea preparations are commonly formulated at a similar concentration to that present in the oral dietary supplement product.
There is still a prevalent misconception remaining from a decade ago that the FDA banned chaparral, a crude, unprocessed form of the Larrea tridentata herb. In fact, the FDA has never banned any products containing this herb. This misconception is likely due to a voluntary moratorium on sales of oral products containing chaparral issued by the American Herbal Products Association (AHPA) and the National Nutritrional Foods Association (NNFA) in the mid-1990s.
