Qufu, China, April 4, 2007 (Market Wire) - Sunwin International Neutraceuticals, Inc. (OTCBB: SUWN), a leader in the production and distribution of Chinese herbs, veterinary medicines and low calorie sweetener (Stevia) in China, announced today its Hypericin-based veterinary disinfectant has proven to be effective in killing 100% of bird flu virus (H5N1) in research tests involving H5N1-infected Chicken embryos.The research was independently conducted by a group of scientists from Ha'erbing Veterinary Institute of the ChineseAcademy of Agricultural Sciences, Animal Influenza Laboratory of the Ministry of Agriculture, and National Bird Flu Reference Laboratory.Hypericin is a derivative of St. Johns Wort.

The test results demonstrated that Sunwin's Hypericin-based veterinary disinfectant eliminates 100% of bird flu virus (H5N1) in the infected chicken embryos within 10 minutes when the Hypericin-based disinfectant was diluted at ratios of 1:5, 1:10, 1:25 and 1:50.No significant toxicities to healthy chicken embryos were observed when the disinfectant was diluted at these same levels.

In November 2005, the Department of Livestock Farming for Shandong Province Government submitted a fast-track application to the Livestock Farming Bureau of China Ministry of Agriculture for approval of Hypericin related products as a class one new veterinary medicine to treat strands of the avian flu virus.This independent study was a requirement of the approval process for the application.
