My acupuncturist suggested I purchase UNDA Natrium Phosphoricum 6× for when I get heartburn. When I get heartburn it's usually very bad. This homeopathic remedy cures it in a matter of minutes. I'm serious and no one has paid me for this review.I ordered Nat Phos 6x for my hyperacidity and dyspepsia and it really helped to manage the issue naturally. (Pls do see your doctor if problem persists) The product is sweet tasting tablet which is a always base of inactive ingredients (it the case of all medicines alt or modern)like sugar or calcium etc and then its coated with active ingredient like Nat Phos with a potency of 6x in this case. You can chew the tablet or dilute in 2-3 tbsp spring or boiled water and take it or add it to your pet’s bowl if its for them. 1-2 pills make a dose. In homeopthy frequency of dose matters not really the number of pills taken at one time. If you’re not familiar with homeopathy and how to use it its suggested to consult a homeopath or read up on the basic first.Large and not great dissolvability for my 3 month old, but works great for my 8 year old for heartburn.solid product.The active and inactive ingredients are not the same and they don’t even have dosing for an infant which is exactly why we got this product. They returned right away which is great and appreciated.
