(If using 30X use 4 tablets) You can use either strength
Nat Phos 6x (or 30X )should help you within 10 minutes after you take it.
Nat Phos is a Biochemic salt and is the Homeopathically potentized chemical Sodium Phosphate. At the potency of 6x the concentration is just 1/1millionth of the salt.
It operates by promoting peristalsis in the stomach and the gut and thereby prevents the formation of acidic conditions which can result if the conditions in the stomach are not conducive to the digestion of food. It will control the problem you have immediately after taking it and should normally cure it in a few days.
I would like to add another unusual characteristic of Nat Phos 6x Or 30X and this is about its almost miraculous effect of helping the person taking it to lose weight at the rate of about 3kg per month. The dose is 2 tablets taken twice daily after lunch and dinner. It also eases bowel movement which is important in the case of the aged and has also been reported to promote deep sleep.
