Holistic medicine used to have a sort of rule of thumb -- for every year you've had a problem it takes a month of natural treatment to fix it. But since everyone is different, some people get better with one treatment and others never get better from a particular treatment. I'd say, don't have specific expectations, just give it a good shot and hope for the best. Meaning, what others have experienced won't really have much meaning for you individually.
It is good but be careful with th hygiene and cleanliness as it can be really dangerous if not sterlized
