따뜻하게 마시면 "위장 근육 이완, 혈류 순환"...더 효과 좋아
When food remains in the stomach too long, it can cause gastric distension, rigidity, or excessive gastric acid secretion, resulting in symptoms like heartburn, chest tightness, belching, and nausea. In severe cases, indigestion can increase intestinal gas, leading to abdominal bloating.
While over-the-counter digestive remedies are available, herbal teas offer a gentler, natural approach to promote digestion and ease discomfort. Warm teas, in particular, relax gastrointestinal muscles, enhance blood circulation, and support smoother digestion. Effective options for relieving indigestion include peppermint, ginger, chamomile, plum, and honey teas. Below, we detail their benefits and recommended consumption methods.
Peppermint Tea: Relieving Bloating and Gas
A study published in a gastroenterology journal reported that 75% of irritable bowel syndrome patients who used peppermint oil capsules experienced symptom relief, underscoring peppermint’s ability to reduce gastric and intestinal spasms while supporting peristalsis. However, those with gastroesophageal reflux disease (GERD) should exercise caution. Peppermint’s muscle-relaxing effects may worsen acid reflux by allowing gastric acid to flow back into the esophagus. Individuals prone to acid reflux should consider alternative digestive teas.

Ginger Tea: Enhancing Digestion and Easing Nausea
Known for its warming properties, ginger tea effectively stimulates digestive functions. Compounds such as gingerol and shogaol protect the gastric mucosa and boost gastric motility, aiding the movement of food through the digestive tract. Ginger enhances gastric blood flow and increases digestive enzyme secretion, making it particularly useful for relieving bloating and heaviness after overeating.
Ginger’s anti-inflammatory properties also promote gut health, easing not only indigestion but also abdominal pain and nausea. Research from Chang Gung University in Taiwan found that ginger accelerates gastric emptying and reduces digestive discomfort. Excessive consumption, however, may irritate the gastric mucosa, so individuals with gastric ulcers or excessive acid secretion should use it sparingly.
Chamomile Tea: Soothing Tension and Heartburn
Chamomile tea, prized for its gentle floral aroma and calming effects, supports digestion by relaxing gastrointestinal muscles. Its apigenin content provides anti-inflammatory and sedative benefits, making it effective for easing gastric tension or rigidity after overeating. Chamomile also curbs excessive gastric acid secretion, making it ideal for relieving indigestion accompanied by heartburn.
Plum Tea: Balancing Acid and Combating Bacteria
Plum tea, a time-honored Korean remedy, is valued for its ability to support digestion and relieve indigestion. Plums stimulate gastric acid and digestive enzyme secretion, helping to break down stagnant food in the stomach and alleviate indigestion symptoms. They also foster beneficial gut bacteria, reducing gas production and abdominal bloating caused by poor digestion. Plums are particularly effective in easing the gastric burden after heavy or greasy meals, a quality that has cemented their role in traditional Korean medicine.
Plums contain picric acid, which offers antibacterial properties that inhibit foodborne pathogens. To prepare plum tea, dilute 1–2 tablespoons of plum extract in 200 ml of warm water. While it can be consumed cold in summer, warm plum tea is more effective for relieving indigestion.
Honey Tea: Protecting the Stomach and Easing Discomfort
Honey tea is a natural remedy that supports digestion while safeguarding the gastric mucosa. As a natural sweetener, honey helps regulate gastric acid levels, easing heartburn and soothing indigestion-related discomfort. Its glucose and fructose components are rapidly absorbed, providing energy without taxing the stomach. Rich in flavonoids and polyphenols, honey offers antibacterial and anti-inflammatory
benefits that support gastrointestinal health.
Warm honey tea relaxes a tense stomach, promotes gastric motility, and aids digestion. By encouraging the growth of beneficial gut bacteria, honey helps alleviate indigestion, reduce bloating, and prevent constipation. Its calming properties also ease stress-related digestive issues. However, due to its high sugar content, those with diabetes or blood sugar concerns should consume honey tea cautiously.
