I've been having quite a bit of success drinking aloe juice on a daily basis. It seems to assist my medication to work more reliably and I've been able to decrease from (2) 25-100 carbi-levo to 1 1/2 per dose. That being a great benefit, a secondary benefit has been wonderful regularity. Prior to the aloe, I was 4-5 days of no activity and then a desperate requirement to use an enema. Not fun!
A friend who has serious ulcers, started using aloe and it has eased his ulcer pain.
