olive oil plus lemon juice didn't cleaned gallstones

Hello There,

My nephew is of 5 years. Recently we came to know that he had gallstone.

We have followed "GALL STONE CLEANSE" program using olive oil and lemon juice.

Basically we used approx. 230 ml Olive-Oil and 110 ml of Lemon juice. Following morning he went to toilet at 7:20 AM. We observed stool at just later part was
somewhat greenish. Again he went for toilet at 8:45 AM and basically we observed many smaller greenish objects in stool.

Following monday we have done scan to see the effects of above theraphy. But unfortunatley gallstone are still presents.

We are little bit disappointed especially boy of such tendor age undergo somuch pain without success.

Can you please suggest further we should do. Your suggestions in this regard would be highly appreciated.
