I have been practicina internal amaroli for more than a year with no noticeable effects on my health. That is, nothing spectacular. Generally my health is much better, but I have also changed my diet and I am fasting when I feel that I will get a sinus infection. On the other side, I have begun practicing amaroli externally just recently, after I got a bad hamstrings inflammation. I was in a state where I couldn't sit on a chair for more than a few minutes. After one week of applying amaroli on my hamstrings, I could definitely see some progress. Now it has been two weeks, and I feel almost pain free. Not only that, but the pain in my right knee (which I had for more than a decade) is almost gone. I can sit on my heels almost - a feat which was unimaginable before. Asanas which were off-limits before are now well within my grasp . Basically, i just rubbed urine to my sinews and left it there for 5 minutes before rinsing it out with a cold water in the morning. Such a simple thing...had to see it to disbelieve it .
