Polygonum species, particularly Polygonum multiflorum (also known as He Shou Wu or Fo-Ti), have a long history of traditional use in Chinese medicine for the treatment of constipation, including in children. Traditional Chinese Medicine (TCM) texts describe preparations of Polygonum as a mild laxative, often attributed to its anthraquinone compounds, which are thought to stimulate bowel movements. The root is sometimes processed to reduce harshness and is usually administered as a decoction or in combination with other herbs to balance its effects and reduce potential toxicity. However, while traditional use is well documented, scientific studies specifically evaluating the safety and efficacy of Polygonum for constipation in children are scarce. There are a few pharmacological studies in adults and animal models that suggest a laxative effect, possibly due to the anthraquinones emodin and physcion, but clinical trials in pediatric populations are lacking. Furthermore, safety concerns have been raised regarding hepatotoxicity with prolonged use. In summary, the use of Polygonum for constipation in children is primarily justified by traditional practice, not by robust scientific evidence, and caution is advised due to potential safety issues.
