This study is the second report from a single experiment planned to determine if acupuncture at LI4 and SP6, or at the sacral points, could produce any harm in the pregnancy outcome of Wistar rats, as has been hypothesised in traditional knowledge. Here, we observe if these points can be harmful to the health of pregnant Wistar rats.


A total of 48 pregnant Wistar rats were randomly divided into 4 groups: total control, where rats were left in cages without manipulation; anesthetised control, where rats were manipulated and anesthetised but did not receive electroacupuncture; and peripheral point and sacral point groups, where rats were anesthetised and received 6 sessions of electroacupuncture at 4 acupuncture points: LI4 and SP6, and BL27 and BL28, respectively. In the 19th day of pregnancy the rats were killed and examined. The primary endpoints were levels of glucose, aspartate aminotransferase (AST), alanine aminotransferase (ALT) creatinine and histological changes of liver and kidney.


There were no differences between the levels of biochemical parameters. No differences were also seen regarding the histopathological analysis.


We found no evidence that acupuncture at the LI4, SP6 and sacral points could be harmful to the Wistar rat dams. Click here to read original article content.
