The gallbladder sits underneath the liver and acts as a reservoir for a substance called bile that is made in the liver and then passed into the digestive tract.
The function of bile is to dissolve fat, a bit like washing-up liquid, so that it can be properly digested in the gut. Quebra Pedra is a small, erect annual herb that grows up to 30 or 40cm in height.
It is indigenous to the rainforests of Brazil, and to other tropical areas. Incidentally, the English term for this little plant is "“saxifrage"”, which derives from the Latin and means – you guessed it – Stone Breaker.
