“At least one million cockroaches have escaped a farm in China where they were being bred for use in traditional medicine after an ‘unknown perpetrator’ destroyed the plastic greenhouse where they were raised. Farm owner Wang Pengsheng invested more than 100,000 yuan ($16,000) in 102 kilograms of Periplaneta americana eggs after spending six months developing a business plan, the report Friday said. The cockroach is generally considered a pest, but believers in traditional Chinese medicine — which uses both plants and animals, including endangered species — say extracts from it can treat diseases including cancer, reduce inflammation and improve immunity.”
