 Well, you only do the natrium muriaticum for two weeks, but you do the fish oil for four weeks. And then call me back next month and tell me what happened, okay? What is the percentage that you have for the natural, you said C30? Yes, it's 30C. On the bottle, it will say natrium muriaticum 30C. That's the strength of the medicine. It's C like Charlie, 3-0-C.
