Greetings,

The oil is practicaly undigestable, so the liver/gallbladder gives all it's bile in an effort to dissolve it. The liver takes up this chime/oil and tries to break it down.

The grapefruit juice stimulates or puckers! Both demand the bile to the aid of the stomach/intestines.

The Epsom Salts is the key, with out it, most liver flushes are worthless to get out large stones.
