Asparagus P(R) cannot compete with first-line diuretics in lowering the blood pressure in treatment-requiring antihypertensives.

Phytother Res. 2009 Mar 9; Chrubasik S, ' Deceased ' CD, Black AA six week clinical surveillance of 163 patients receiving maximally tolerable doses of Asparagus P((R)), a proprietary mixture pulversied dried asparagus root and parsley leaf, has not indicated any clinically useful antihypertensive effect. The profile of adverse events (with 7 patients leaving the surveillance early because of renally related complaints) contraindicates its use in hypertension or to promote flushing of the efferent tract in rental inflammatory conditions or urolithiasis.
