The milk cows produce during the first few days after giving birth may help save thousands of human lives as it can be used to treat a number of stomach complaints, revealed scientists from London's Hammersmith Hospital and Leicester General Hospital. The by-product of the milk, bovine colostrum, could save many lives every year, the scientists say, as one of the proteins contained in the matter has been shown by a recent study to help treat problems caused by non-steroidal anti-inflammatory drugs (NSAIDs). These useful drugs can cause gastric bleeding by attacking the stomach lining and their side effects are responsible for about 2,000 deaths every year.
