Would these work better than Cayenne? My aunt has diverticulosis and diverticulitis and doesn't do internet, so I am about to order some of this and send it to her. She's a believer now, and has no desire to have surgery to repair her intestines and is trying aloe vera juice now, but it tastes nasty (I tried it). She got ahold of some cherry flavored stuff that isn't so bad and is about to do a Colon cleanse. The pepper would be for after, to heal the thin, irritated walls. Not sure how much to use if it is so much higher in heat units. Is it possible to take too much? She is nearly 70.
