Within about 2 weeks liver function improves and jaundice abates. Stool and urine color should return to normal, pruritus should be relieved, and the patient should be more comfortable. The biliary catheter does not cure the biliary obstruction.
The parsnip (Pastinaca sativa) is a root vegetable closely related to the carrot and parsley. It is a biennial plant usually grown as an annual. Its long tuberous root has cream-colored skin and flesh and can be left in the ground when mature as it becomes sweeter in flavor after winter frosts.
By this time, the stem is woody and the tuber is inedible. The seeds are pale brown, flat, and winged. The parsnip is native to Eurasia. It has been used as a vegetable since antiquity and was cultivated by the Romans, although some confusion exists in the literature of the time between parsnips and carrots. It was used as a sweetener before the arrival in Europe of cane sugar. The parsnip is usually cooked, but can also be eaten raw.
