Liver flush/master cleanse and bile

Greetings,

I am really curious about one issue I have.. and I can't find the answer anywhere.

Last year I did the MC but my main problem was that basically I had a sickly yellow tint to my skin and eyes (my eye whites were really yellow).

This same happened to me recently when I did a small liver cleanse/flush (not the Hulda Clark one). I was again all yellow for maybe 5 days. Then my eyes started to clear up again. After another 2 days my eyes were bright white with almost a blue tint (just gorgeous). But after some days it went back to 'normal' white. I never had really white eyes, always a little yellowish and veiny.

But why doesn't it stay that nice white colour? And why do I get that yellowing issue in the first place? It's obviously something with the gallblader and bile...

Thanks
