Two lemons squeezed with an equal amount of olive oil should be gentle enough to relieve gallbladder pain. Make sure you take it on an empty stomach. Also magnesium citrate powder ( I use Natural Calm) 2TBSP in glass of warm water will help release stones/sludge/liver toxins, also take on an empty stomach. The Epsom Salt is in the classic Liver Flush recipe but I find it really hard on the kidneys/adrenals. So the mag citrate is a better option and helps reduce stress as well.
