Asparagus is a perennial plant that requires special cultivation. Early in the spring, its sprouts can be harvested and eaten, while later in the season, the developing flowers may be consumed in a manner similar to corn on the cob.
Asparagus is rich in protein, fiber and vitamins - especially vitamins B1, B2 and C. Some of the health benefits of asparagus include maintenance of the kidneys and urinary tract and cleansing of the digestive system. Pharmacological and clinical research also indicates that asparagus has an antibiotic effect. Recently, asparagus has been employed by herbalists in the treatment of rheumatism and edema arising from heart failure.
