Constituents
Asparagus contains steroidal glycosides (asparagosides), bitter glycosides, asparagine, and flavonoids. Asparagine is a strong diuretic.
History & Folklore
To judge from ancient Egyptian tomb drawings, asparagus was cultivated as long ago as 4000 BCE. In the 1st century CE, the Greek physician Dioscorides recommended a decoction of asparagus root to improve urine flow and to treat kidney problems, jaundice, and sciatica.
Medicinal Actions & Uses
Asparagus is a strong diuretic that is useful for a variety of urinary problems, including cystitis. It is also useful for rheumatic conditions, helping to “flush” waste products accumulated in the joints out of the body in the urine. Asparagus is also bitter, mildly laxative, and sedative.
Caution
Do not take if you suffer from kidney disease.
