Here's a use for potatoes as 'prescribed' by my Dentist. I was having repeated pain in my jaw, so made an appointment to see my Dentist. She diagnosed GERD from the discoloration on my teeth. Then she recommended that I boil a potato and drink the potato water to treat it.
My Dr prescribed Pepcid; I was SICK for 4 days after taking it.
So now I use potato water. But I cheat and use a teaspoon of mashed potato mix in a glass of warm water instead of boiling a potato. Seems to work.
It probably helps that I cut way back on Ibuprophen...
