What we are discussing here, are ox gallstones. Gallstones are mineral deposits (and not of organic matter) mainly found in bovines gallbladders.

We make a distinction between different kinds of Ox gallstones, depending on their size, shape and colour, each of these holds a significant commercial value.

Size / Weight / Shape / Colour

Gallstones look like stones of various shapes and colours.

Two main shapes : egg-shaped or pyramid-shaped.
Two distinct colours : Orange brown, or dark brown close to brownish black.

Some gallstones can be as big as a hens-egg (whose weight can reach 100 grs), but the average gallstone will be more likely the size of a pigeon's egg, weighing around 10 grams.


Gallstones develop inside a number of bovines, mainly depending on their age and diet.

They are essentially located in the gallbladder.

The bovine race is quite diverse. It includes, depending on the countries: cows, oxen bulls, buffalos, zebus, bison's, yaks, gaurs...


Ox gallstones are used in the pharmacopeia.

They are used in medical formulas because of their sedative, anti-inflammatory and antipyretic properties.

They are in particular used for treatments of hepatic problems.
