Is there any natural herbs that a pregnant woman can take for gas?

Fennel, Aniseed and Peppermint are good herbs for dispelling gas. They can be taken as tinctures or made into tea, three times a day before meals. These and other digestive herbs such as coriander, ginger, oregano and savory may be added to cooking to make food more digestible, avoiding the gas.

ginger. I use it mainly for nausea and stuff the bottom link shows some info. By increasing the production of digestive fluids ginger does help with gas as gas is caused by peutrification of food that can't digest well. for the post underneath this one, taking large amounts of peppermint may encourage the start of menstrual periods. Therefore, its use during pregnancy is not recommended.(third link). See the second link below it shows herbs that should not be used during pregnancy and fennel is on it too as it is a uterine stimulant.
