Efficacy and safety of echinacea in treating upper respiratory tract infections in children: Echinacea is a widely used herbal remedy for treatment of upper respiratory tract infections (URIs). However, there are few data on the efficacy and safety of echinacea in treating URIs in children. Echinacea purpurea, as dosed in this study, was not effective in treating URI symptoms in patients 2 to 11 years old, and its use was associated with an increased risk of rash Read More Echinacea and truth in labeling Echinacea sales represent 10% of the dietary supplement market in the United States, but there is no guarantee as to the content, quality, variability, or contamination in Echinacea preparations. Echinacea from retail stores often does not contain the labeled species. A claim of "standardization" does not mean the preparation is accurately labeled, nor does it indicate less variability in concentration of constituents of the herb.

Alternative herbal medicines are projected to be a $5 billion market by the turn of the century. Echinacea is an extremely popular herbal supplement; sales are nearly $300 million a year according to the last figures available. Sweeping deregulation of botanicals now permits echinacea to be sold to the public without proof of safety or efficacy if the merchandiser notes on the label that the product is not intended to diagnose, treat, cure, or prevent any disease.

Read More Use of dietary supplements in cancer patients In 1996, total sales in dietary supplements were $9.8 billion, and it is estimated that 35–50% of the general public currently use dietary supplements (Nutrition Business Journal 1999 ). Sales are continuing to grow. In 1998, consumers were spending $13.9 billion on supplements, which was 51% of the total sales in the United States nutrition industry. The top five single botanicals sold in the United States in 1997 were echinacea (7%), ginseng (8%), ginkgo (7%), St. John’s wort (6%) and garlic (6%) (Nutrition Business Journal 1997 and 1998 ). Multiherbal products comprised 27% of the total sales. Read More |
