Sri Lanka: A newly formulated herbal drug of C. grandis (500 mg per day) significantly improved blood sugar control in patients with newly diagnosed type 2 diabetes (T2D), according to a recent study in the journal Phytomedicine.

Several preclinical studies have shown the aqueous leaves extract of Coccinia grandis (Linn.) Voigt (Cucurbitaceae) to be promising for the in vivo and in vitro diabetes treatment. The present study by Keddagoda Gamage Piyumi Wasana, University of Ruhuna, Galle, Sri Lanka, and colleagues evaluated the efficacy and safety of a newly developed herbal formulation of C. grandis in newly diagnosed patients with type 2 diabetes mellitus.

For the purpose, the researchers conducted a three months long, randomized, double blind, placebo controlled clinical trial in patients with newly diagnosed T2D. The trial from the University Medical Clinic, Teaching Hospital, Karapitiya, Galle, Sri Lanka, recruited 158 newly diagnosed patients with T2DM based on fasting plasma glucose (FPG) concentration. They were randomly assigned to receive 500 mg of herbal drug (test group; n = 79) or placebo drug (placebo group; n = 79) once daily for three months.

Patients and investigators were blinded for the treatment. Percentage of glycated hemoglobin (HbA1C %), insulin and lipid profile parameters were estimated at the base line and at the end of the intervention. Serum concentration of fructosamine was assessed at every other visit of the trial.

The homeostatic model assessment for insulin resistance (HOMA-IR), atherogenic index (AI), cardio-protective index (CPI) and coronary risk index (CRI) were calculated. Fasting plasma glucose concentration, renal and liver toxicity parameters, hematological parameters, blood pressure (BP) were assessed throughout the study in two weekly intervals till the end of three months.

A total number of 145 patients completed the entire clinical trial period successfully.

Key findings of the study include:

Mean (SD) changes of variables from the baseline to the end of the intervention in test and placebo groups were 0.65 and 0.08 for HbA_1C %, 1.91 and -1.28 for insulin, 0.02 and -0.01 for frucosamine, 1.51 and 0.05 for FPG, 1.73 and -0.37 for HOMA-IR, 0.16 and -0.04 for TG, 0.07 and -0.02 for VLDL-C respectively.
The herbal drug of C. grandis was unable to change other outcome variables significantly when compared to the placebo.
All the renal, liver and toxicity parameters, hematological parameters and BP were within the normal physiological reference ranges at each visit.

"Our findings demonstrate that treatment with herbal drug of C. grandis (500 mg per day) for three months for patients with newly diagnosed T2DM significantly improved their glycemic and selected lipid profile parameters with well tolerated safety," concluded the authors.
