Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Camellia sinensis, the plant from which green and black tea are derived, has a traditional history of use for addressing mild digestive complaints, including nausea and vomiting. In various cultures, particularly in East Asia, tea made from Camellia sinensis leaves has been consumed after meals to aid digestion and alleviate queasiness. The mild astringency, warmth, and presence of certain polyphenols and methylxanthines (such as caffeine and theobromine) are sometimes thought to contribute to these effects.

However, scientific evidence directly supporting Camellia sinensis for the treatment or prevention of nausea and vomiting is limited. Most clinical research on Camellia sinensis focuses on its antioxidant, cardiovascular, or metabolic effects rather than gastrointestinal symptom relief. Some animal studies suggest potential antiemetic properties, possibly related to its antioxidant action or mild stimulation of gastric motility, but these findings have not been robustly confirmed in human clinical trials. Traditional use, especially as a mild and palatable beverage, remains the primary basis for its use against nausea.

In contrast, other botanicals such as ginger (Zingiber officinale) have much stronger scientific evidence for anti-nausea effects. Overall, while Camellia sinensis is widely consumed and may offer comfort in the context of mild digestive upset, its use for nausea and vomiting is best characterized as tradition-based and only weakly supported by scientific evidence.
