Is rock salt good for health?Today when I visited a super market, I found Rock salt in the name of various companies. Tata company is also selling this salt. When I go through the in formation on those different company packets they are saying 80 odd minerals will be there in this salt in which some pink salt granules also there. The benefits mentioned due to use of this salt-improvement in digestion, improves respiratory problems, improves circulation, pH levels of the body balanced, quiter sleeping will be improved etc. But the cost of this salt is around Rs. 65, 90- 99 etc. Previously I am using Tata low sodium salt. Members do you have any experience with rock salt? Is it good for health or it is market tactics?
