There are several people who recommend certain kinds of salts claiming to have healthy minerals or even various kinds of additives including baking soda.You may call us conservative, but we believe that only Pure Salt should be used WITHOUT additives. While this is not to decry other recommendations, it is just that WE are not convinced on the long-term implications of any additive or chemical on the body. In fact, we even don't recommend table salts that are iodized.Salt has been used for centuries and shown to have tremendous benefits. For jala neti, we would recommend only Pure Salt - the purest you can get. It should contain no additives nor be iodized and should NOT have any anti caking agent.
