Well I havent had any specific stomach ailments before and neither do I take blood pressure medicines. I have been taking the lime juice for few days now, no complaints, as yet, touchwood!
I have not heard that about Lime Juice. I know some put some Lemon Juice in their water to help with digestion, and some will eat a grapefruit a day for weight loss, but, being these are all "citrus" and "acid" I would be very careful, especially if you are susceptible to stomach problems or have an ulcer.
Also, if on certain blood pressure meds, be careful, citrus fruit can cause a bad reaction if taken with these drugs.
