Barberry
Berberis is a perennial shrub, native to Europe. The leaves and berries are used medicinally.
Berberis contains the alkaloid berberine, which stimulates the secretion of bile and bilirubin, supporting its use for gallstones and sluggish digestive problems. As a bitter herb, it stimulates the digestive process in a positive way.
It should not be taken alongside other medication for gallstones, or by those with liver problems, kidney disease and inflammatory diseases of the gastrointestinal tract without consulting the Doctor concerned.
