I haven't tried nopal but it sounds similar to aloe vera. Some IBDers swear by aloe vera but many more were less impressed. One advantage nopal may have over aloe vera is that it is hard or even impossible to find the juice without any added crap like citric acid. Apparently you can prepare nopal cleanly without added ingredients. Just cut it up and add water.
