I have taken Julia Chang's Herbs twice, and had tinnitus, so I think I can help you with your question.
First, I have had the symptoms of tinnitus for about 20 years. I uncovered it while at a meditation seminar in silent retreat in a quiet cell for 10 days. All of a sudden, I noticed I had a ringing in my ears. I think it was also due to having poison ivy throughout my body and putting a lot of medications on me. Who knows, but since then I've had it.
And I have tried all types of things to alleviate the ringing. One thing that I have found to work for me is Chinese herbs. They've helped me through a lot of life ailments over the years, and I have found Tai Chi very beneficial. So, when I found out through research that the particular type of tinnitus I had (the type where it rings inside your head and has nothing to do with the hearing in the ears) is to do Chinese cleansing of the liver.
The first week I took these herbs by Julia Chang, the ringing got much worse. But, I also found myself sleeping like a rock and could tell that it was working. You have to realize that the tinnitus, according to Chinese medicine, is caused by a congested liver, and decongesting it is going to push the toxins outside of it into the body, and many of those go straight to the head.
Anyway, I would just say to continue on with the cleanse. I had to do 2 cleanses over three months, one sixty day and one thirty day, before I was able to flush out all the toxins. And the tinnitus is greatly relieved. Not all gone, but I have flushed out a lot of the liver and gallbladder toxicity and it is lessening.
