Plantago, specifically Plantago ovata (psyllium husk), is widely recognized for its role in treating constipation, including in children. Psyllium is a soluble fiber that absorbs water in the gut, forming a gel-like substance that softens stool and increases its bulk, thus promoting regular bowel movements. Its efficacy in managing constipation is supported by a substantial body of scientific literature, including randomized controlled trials and clinical guidelines.

The American Academy of Pediatrics and other reputable organizations recommend dietary fiber supplementation, such as psyllium, as a first-line therapy for functional constipation in children. Multiple studies have shown that psyllium can significantly increase stool frequency and improve stool consistency in pediatric populations with chronic constipation. For example, a randomized controlled trial published in Pediatrics (2011) demonstrated that psyllium fiber was effective and well-tolerated for treating childhood constipation compared to placebo. Systematic reviews also note its safety profile and effectiveness, although some children may experience minor gastrointestinal side effects such as bloating or flatulence.

In summary, the use of Plantago ovata (psyllium) for childhood constipation is well-supported by scientific evidence, and it is endorsed by clinical practice guidelines as a safe and effective treatment option.
