Why do we taste bile in mouth

I posted this question before and no one responded. Thought I would try again.

What is the mechanism that causes the "bile" taste in your mouth when the liver/gallbladder are congested? I just want to understand the physiological mechanism at work here.

I still get this taste in my mouth. After almost 30 flushes I am still getting out stones. I don't get many out at a time (sometimes none) but they are still coming and I still have symptoms.

Thanks. Tweet
