Black tea
Camellia sinensis is the plant that produces black tea. It is frequently brewed with other plants in variants like Earl Grey and English Breakfast. This tea has a number of beneficial ingredients. These contain theaflavins, an antioxidant that may prevent stomach ulcers, and thearubigins, which may alleviate indigestion. In one study, black tea and theaflavins were given to mice with stomach ulcers for 3 days, and it was shown that by reducing inflammatory substances and pathways, 78–81% of the ulcers were cured.
Another mouse study discovered that black tea extract relieved delayed stomach emptying and the accompanying dyspepsia induced by medication. As a result, while drinking black tea may aid digestion and protect against ulcers, additional study is needed. Before consuming, steep a black tea bag in 1 cup (250 ml) of heated water for 5-10 minutes. If you use loose black tea leaves, filter the tea after steeping.
