I found one “burping” testimony on the HEO website. It's on the Warrior detail page, but I agree with Linda's comment, that it's most likely related to diet:
16. You all know about yucky sulfur burps...the ones that can chase anyone away....LOL! 'Warrior,' our new little buddy in a bottle, got rid of these burps after a few hours. Usually this condition lasts for days! I myself personally came down with the yucky burps late after supper and immediately took a full capsule full of Warrior (about 20 drops) and repeated this before going to bed. I was burp free all night, and they did not return. My sister's also had the same results. We are all so happy we don't have to suffer with these burps anymore (or should we say everyone around us) ;-) - Elizabeth P.
[HEO's Comment: 20 drops of Warrior seems excessive. Burping is related to the parasympathetic nervous system, as is poor digestion, bloating, high cholesterol, weight gain, etc. A diet high in fats, fried foods, sugars, white wheat and red meat can lead to too much PNS and weight gain. It can also result in sinusitis, stuffy noses, chronic immune related problems in the head and chest. If you feel to give the Warrior a try, we'd suggest a single drop and fill the rest of the capsule with carrier oil.]
