Now, the RSS's Cow Protection Department has invented a new urine-based soft drink it hopes will promote its health-giving properties to a wider market. "We refer to gau ark (cow urine) as gau jal (cow water) as it has immense potential to cure various diseases. We have developed a soft drink formula with gau jal as the base and it has been sent to a laboratory at Lucknow for testing," said director Om Prakash.
