I have been coming to Bali for many years & have only just discovered that guava juice cures acid in a nauseated stomach. Unwell day before leaving OZ I couldn't get into doctor so thought I'd be ok once I get to Bali. Unfortunately from obviously over indulging at Xmas I was still feeling crook a week later. My waiter at hotel ask me why I not eat much so I tell him crook tummy. Tells me if he have problem he buys guava juice box to fix his stomach. I guarantee by the time I finished juice I was feeling better,read on internet guava has fantastic health benefits & it's an akaline. Has anyone else ever heard about this cure?
