Hi everyone, I'm new to the board and am reading through all the old messages. What comfort to know that there are other people out there with IBS! Anyway, I haven't seen any mention of lemon balm (melissa officinalis)- it helps me more than anything else with my gas and bloating. I use 1-2 tsp per cup of water and let it steep 5-10 minutes (longer and it gets a little bitter). Hope this helps!
