(Fortunately, most people never have any problems with their diverticula, so there's no need to perform surgery merely to eliminate diverticula that have formed.)
Repair torn diverticula. This meizitang botanical slimming soft gel condition is more critical than merely having diverticula. Now, those diverticula have torn open and they're releasing poisons into your body. Again, there's no evidence that garlic pills can make your body knit those wounds closed. And the pills certainly can't take out a needle & thread, and sew up the tears!
Prevent diverticula from forming. Diverticula form because a person's diet doesn't have enough fiber. That is, plain and simple, the root cause of the problem. Theoretically, you could get your fiber by eating about 300 garlic cloves every day.
Of course nobody will do that. A more reasonable amount of consumption, like five or six cloves per day, will bring you less than one total gram of dietary original 2 day diet fiber. That's negligible when your aim is thirty or forty grams of fiber per day.
