In 2004, Israel's Health Minister began an investigation into Herbalife's products after four persons using Herbalife's products were found to have liver problems. The company was accused of selling products containing toxic ingredients such as quaqua, comfrey, and kraska. The products were sent to Bio-Medical Research Design LTD (B.R.D), to a private U.S. laboratory, and to Israel's Forensic research laboratory. A study of the cases funded by the Israeli Ministry of Health concluded that there was a causative relationship. Herbalife's SEC 10-Q filings stated that the Israeli Ministry of Health did not establish a causal relationship between the product and liver ailments. In 2009, an Israeli woman sued Herbalife International and Herbalife Israel, claiming that her liver damage resulted from the use of Herbalife products.
