The cystine calculi’s, consisting primarily of amino acids, is considered the rarest stones with a prevalence of 1% with adults and 10% with the gallstone child. Its treatment is difficult because of its resistance to extracorporeal lithotripsy and its frequent recurrence. Drug treatments used until now, based on citrate are effective, but often poorly tolerated. Morocco is one of the countries that has been using, for a long time, traditional medicine based on natural plants to treat many diseases including stones. The most medicinal plants used for this purpose are Herniaria hirsuta L. (HHL) , flowrs of Opuntia Ficus- Indica (OFI) , Zea Mays Styles ( ZMS ) and seeds of Ammi Visnaga L. (AVL) . The objective of this work is to study experimentally the effectiveness of each plant on the dissolution of cystine stones.
