The digestive system plays a central role in breaking down food, absorbing nutrients and removing waste from the body. However, claims that certain drinks can “cleanse” the gut or remove accumulated toxins should be treated cautiously.
The lower oesophageal sphincter is a ring of muscle that controls the movement of food from the oesophagus into the stomach. The stomach then mixes food with digestive juices, including acid and enzymes, before gradually passing it into the small intestine.
Ginger
Ginger is widely used as a food and traditional remedy. Research suggests it may help with some forms of nausea and may reduce the severity of menstrual cramps. However, there is not strong evidence that ginger tea “detoxifies” or cleanses the digestive tract. Ginger can also cause heartburn, abdominal discomfort or diarrhoea in some people.
Moringa
Moringa leaves are nutritious and are consumed in many parts of the world, including as tea. However, claims that moringa tea cleanses the gut, treats gastritis or prevents colon cancer should not be presented as established medical facts without stronger human evidence.
Garlic
Garlic contains biologically active compounds and can form part of a healthy diet. However, eating garlic should not be described as a way to remove dangerous chemicals from the stomach or control stomach acid. People with digestive conditions may also find that certain foods worsen their symptoms.
Lemon or citrus drinks
Lemon water can contribute to fluid intake and citrus fruits provide nutrients. However, there is no good evidence that lemon drinks “flush toxins” from the digestive system.
Overall, a balanced diet, adequate fluids, physical activity and appropriate medical care are more reliable ways to support digestive health than relying on detox claims.
