The applicant should complete the missing data and respond to the reviewers' comments in addition to the following:
The title lacks names of herbs, the study population, and the place of the study.
The data about human patients (study population and design, groups, sampling, and sample size) are not stated. I recommend including a co-author with an MD in public health or epidemiology.
The flow chart lacks the methodology, study design, groups, etc.
The informed consent form needs to be trimmed of unnecessary data and instructions to the researchers to avoid confusion among the patients and to shorten the form. more details of the procedures to the patients are required.
Are these herbs (gel and cleanser) used before or are they new preparations?: Please cite the references.
