Lemongrass (Cymbopogon citratus) is a tropical grass widely used in Asian cuisine for its bright, lemony flavor. Beyond its culinary appeal, this plant has been a staple in traditional medicine systems for centuries, often consumed as an herbal tea. Many people use it as a home remedy for various digestive complaints. A common query is whether this popular infusion acts as a direct laxative to support bowel regularity.
Lemongrass and Bowel Movement Claims
Lemongrass is not a strong laxative like senna or cascara, and scientific evidence for this specific action is generally lacking. Traditional uses often cite its ability to alleviate digestive discomforts such as stomachache, gas, and bloating. This traditional application has led to the belief that it promotes bowel movements.
Modern research has not classified lemongrass as a primary stimulant laxative. Studies have indicated that its aqueous extract may promote gastrointestinal motility in animal models, suggesting a potential benefit for slow transit constipation. The perceived effect is likely a secondary outcome resulting from its soothing properties and other physiological effects.
How Lemongrass Affects Hydration and Digestion
Lemongrass contains natural compounds that influence digestive comfort, which may be misinterpreted as a direct laxative action. The essential oil contains citral, a phytochemical studied for its anti-inflammatory and muscle-relaxing properties. These properties help soothe the gut lining and reduce spasms in the gastrointestinal tract, mitigating cramping and bloating.
This reduction in discomfort and easing of spasms indirectly supports regular bowel function. Lemongrass is also a known diuretic, increasing the frequency of urination and helping the body manage excess fluid. When consumed as a hot tea, the increased fluid intake combined with this diuretic action contributes to overall hydration. Optimal hydration is a primary factor in preventing constipation because it softens stool, allowing it to pass more easily. This hydration effect is the most likely source of the plant’s reputation for promoting regularity.
Safe Consumption Guidelines and Side Effects
Consuming lemongrass tea is generally safe in typical amounts, such as one or two cups daily. To prepare a standard infusion, steep one teaspoon of dried lemongrass or one to two lightly bruised fresh stalks in hot water for five to ten minutes. The resulting effects are dose-dependent, meaning higher amounts may yield a stronger result.
The primary potential side effect relates to its diuretic properties, which can increase the risk of dehydration if consumption is excessive and not balanced with sufficient water intake. Individuals who are pregnant or breastfeeding should consult a healthcare provider before using lemongrass medicinally. People with existing kidney issues or those taking certain medications, particularly diuretics or blood pressure medication, should exercise caution due to the plant’s effect on fluid balance.
