Abstract

Objectives : in recent years, there have been some case reports about liver injuries suspected to be caused by Heshouwu, the root of Polygonum multiflorum. So, I investigated liver function tests of patients who had taken Heshouwu, to know whether Heshouwu was hepatotoxic.
Methods : I surveyed whether Heshouwu caused liver injury in patients, who had been admitted and taken Heshouwu at Dongguk University International Hospital, from May 2005 to July 2008. I looked over all the liver function tests of those patients, done during medication and 30 days after.
Results : Among 1,449 inpatients, there were 124 patients who had taken Heshouwu. Among those 124 patients, 14 cases whose liver function tests were abnormal before medication were excluded. 69 cases who did not take liver function test 30 days after were also excluded. As a result, 41 patients were enrolled, and their mean dosage was 14.04(8-24) g/day, and the mean medication period was 13.8 (1-89) days. During and after medication, there were no abnormal liver function test results at all, in the enrolled cases.
Conclusions : Roughly speaking, according to the above results, it seems that taking Heshouwu for about two weeks as per the commonly taken dosage did not cause hepatotoxicity, though we needs more laboratory and clinical research to reach a more definitive conclusion.
