It's not just organge peel!!!
I used it for a couple of weeks (tried just about everything) but it didn't help me, only the DGL helped cure my GERD in one month.
I'll write what it says on the box (and it was expensive by the way) Orange (citrus sienensis) 1,000 mg. - Peel Extract standardized to contain a minimum of 98.5% d-limonene. It's a softgel capsule.
It also give a WARNING-DO NOT TAKE IF YOU SUSPECT YOU HAVE AN ULCER OR HAVE AN ULCER.
