Litrix Dietary supplement Food supplement based on Phillantus niruri and Citrates The filanto called \"spaccapietra grass\" can interfere with some important stages in the process of crystal formation, such as aggregation and can influence its structure and composition. The possible action on the growth of crystals and the property of smoothing the surface of the calculation, consequently facilitates their elimination. Therefore, besides its litholithic activity, it also has an antispasmodic, decongestant, antibacterial and diuretic action. It favors the peristalsis of the urinary excretory way, favoring the progression of the calculation. Potassium and magnesium citrate may be useful for increasing urinary pH so as to make the urine more alkaline. This increase reduces the precipitation of uric acid crystals, making them soluble in urine. Furthermore citrate has a direct inhibitory action on spontaneous nucleation and on the growth of CaOx and CaP crystals. The alkaline Citrate, increasing the urinary pH decreases the formation of calcium oxalate crystals.
