Cochran reviewed five trials about Medicinal Herbs. Medicinal Herbs are to correct the imbalance of the Yin-Yang. One small trial compared Chinese medicinal herbs to demopressin, herbs showed improvement but the group was too small to see a significant difference. Three trials compared medicinal herbs to imipramine and showed improvement and a decreased failure rate after stopping treatment. The fifth trial compared medicinal herbs to meclofenoxate and it was not more effective. All of the trials were small, had questionable quality, and did not have a placebo group. Evidence was thought to be weak.
My opinion: I am incredibly leery of any supplement that is not FDA approved. Medicinal herbs can be unregulated and dangerous. I’ve had parents ask me to review a long list of herbs their child was taking to verify that they were safe.
I am still unable to confirm what is in dragon bone so I refuse to support the use of it.
