Effect of herbal extract mixture Silybum marianum, Melissa officinalis, Vaccinium arctostaphylos, Trigonella foenum, Urtica dioica, and Citrullus colocynthis on blood sugar control in type 2 diabetic patients
Design
This double-blind, phase 2 clinical trial is performed in 60 type II diabetic patients divided equally in herbal and placebo groups. The herbal drug and placebo with code A or B who no one except laboratory expert aware of its contents are prescribed to patients for 3 months.

Patients are aware that they are either in the herbal drug or placebo groups, but they are not aware of the type of group they are in.
Participants/Inclusion and exclusion criteria
Inclusion criteria: Type II diabetic patients; 40 to 60 years old; fasting blood glucose levels 130 to170 mg/dL; glycosylated hemoglobin 7.5 to 8.5%
Exclusion criteria: Patients with a diabetic foot ulcer, gangrene or any severe illness and who tend to change their exercise program or diet
Intervention groups
Intervention group: Patients in this group receive a 500 mg capsule of herbal drug twice a day after breakfast.

Randomization (investigator's opinion)
Randomized
Randomization description
For randomization, a random number table and block randomization method is used. In this method the patients are assigned into blocks of 2 patients (total 30 blocks). Then, each of the 2 patients entered the block of herbal drug or placebo, with 30 patients assigned to each group. There is no significant difference in fasting blood glucose and glycosylated hemoglobin in each group.
Blinding (investigator's opinion)
Double blinded
Blinding description
Package for herbal and placebo is labeled with code B or A. Other specifications on the labels are identical. Physicians, nurses, patients, data collectors and those who evaluate the outcome are unaware of the drug and placebo group. Only laboratory expert knows the types of the groups. Patients are aware that they are either in the herbal drug or placebo groups, but they are not aware of the type of group they are in.
