Ah, Yes!
Dandelion Root, Oregon Grape (berberis), Nettle, and Milk Thistle. If the gallbladder needs to be woken up then your liver needs assistance also. It goes hand in hand.
Use the tinctures. Or get a tincture from a reputable company than combines the herb make sure you have at least Dandelion, Oregon Grape (berberis) in it. Make sure its a reputable place. Don't go for glycerin go for the alcohol blends. Reason is that the glycerin does not extract the same constituents as the alcohol. You want ALL the constituents of each plant. If you are adverse to alcohol tinctures, put the drops in hot tea and wait a few minutes before drinking. The alcohol will dissipate. But there really is not enough in the tincture to be a nuisance even with liver damage from alcohol, but if a person is a recovering alcoholic best not use the alcohol tincture. Find a few more herbs that work with the liver. Burdock Root is another good one.
