I first got to know about this product when my sister came down from us, and got it with her. As I was having a backache, she applied the product, and believe it or not, I was feeling much better after that, with a sense of warmth as if fomentation is being given. I is a great product to use as a pain reliever for small aches and pains as you can avoid taking pain killer tablets which cause gastritis, and acidity. Also there are no side effects. Only thing is is it costly, as it’s an imported brand, but for those who can afford it, it’s a great first aid box medicine.
