It's well-known that epazote is said to reduce flatulence from bean dishes.
Bean dishes don't tend to give me gas, but they feel a lot more nutritious to me if I add epazote. I get a stronger feeling of well-being and have more of an appetite for the food. I don't know if it affects anyone else that way. I noticed that I got such a feeling with sweet potatoes in a soup, too (which soup had epazote). Anyway, I tolerate sweet potatoes okay (not perfectly), but they feel much better with the epazote! I wonder what kinds of sugar they contain. I similarly don't know if epazote helps anyone else with sweet potatoes.
