The manuscript by Alison Maunder et al is a systematic review on the effectiveness of herbal medicines for weight loss. The weight reducion effect of RCTs on several different herbs including Camellia sinensis and Garcinia cambogia were meta-analyzed respectively.

The weight reduction effect of natural herbs deserves more attention and research. The review summarizes relevant studies and finds that there is currently insufficient evidence to recommend any of these herbal medicines for the treatment of excess weight.

Here, I have only one comment. It would be better, if the authors focused on just one herb, such as Camellia sinensis (green tea) and performed in-depth analysis and discussion with its chemical ingredients and known pharmacological effects.

The authors have answered the question raised by the reviewer. I have no further comments.
