Gut health is broad, so the best tea depends on what you’re trying to support. For general digestive comfort, ginger and peppermint have the strongest evidence. For gut motility — keeping things moving — ginger and senna-based teas are commonly used, though senna should only be occasional. For the gut microbiome specifically, prebiotic-rich foods matter more than tea, though green tea polyphenols have shown some benefit for microbial diversity in small studies. Staying well-hydrated overall is one of the simplest and most effective things you can do for gut health — herbal tisanes contribute to that daily fluid intake without caffeine or added sugar.
