The Effects of Pig Trotter on Lactation: A Systematic Review
Kwon Chan-Young

Lee Bo-Ram
Abstract
Objectives: This study was conducted to investigate randomized controlled trials (RCTs) using pig trotter on lactation and to determine its clinical efficacy.

Methods: All relevant studies were searched in seven medical databases and were reviewed by independent two authors. Risk of bias tool was used to assess the quality of the included studies.

Results: A total of eight RCTs were included in this review. In maternities with hypogalactia, pig trotter showed positive effects on lactation and breastfeeding compared to routine postpartum care or high-calorie/high-protein diet, however it was not effective compared with medical intervention such as other oriental herbal medicine, tuina, and acupressure. In maternities without hypogalactia, pig trotter showed positive effects on lactation and breastfeeding compared to routine postpartum care or high-calorie/high-protein diet. One study reported that gastrointestinal symptoms occurred in 5.36% of the group taking pig trotter. The risk of bias on included studies were generally unclear or high.

Conclusions: Pig trotter can be used as supplementary maternity diets or decoctions for the purpose of promoting lactation and breastfeeding. However, higher quality, racial specific, and long-term studies should be performed to confirm its efficacy and safety.
