Rating (out of 5): 2

Camellia sinensis, the plant from which green, black, and oolong teas are derived, has a long history of traditional use for digestive complaints, including acid indigestion. In various Asian cultures, drinking tea after meals has been a common practice believed to aid digestion and reduce symptoms such as bloating and dyspepsia. Historically, this practice is rooted in anecdotal evidence and traditional herbal medicine rather than in robust clinical research.

From a scientific perspective, there is limited direct evidence supporting the use of Camellia sinensis for acid indigestion. Some studies suggest that certain constituents of tea, such as polyphenols, may exert mild anti-inflammatory or gastroprotective effects. However, other research indicates that caffeinated tea can relax the lower esophageal sphincter, potentially worsening reflux symptoms in susceptible individuals. Overall, there is no strong clinical trial data demonstrating that Camellia sinensis tea effectively treats or prevents acid indigestion.

In summary, the use of Camellia sinensis for acid indigestion is primarily justified by tradition, with only weak or conflicting scientific evidence to support its efficacy. Its use for this purpose should be considered with caution, especially for individuals who are sensitive to caffeine or who have significant gastroesophageal reflux disease (GERD).
