Phase 1
Completed
Conditions

Hypertension
Interventions
Dietary Supplement: Ginseng
Dietary Supplement: Wheat Bran
Registration Number
NCT01578837
Lead Sponsor
Unity Health Toronto
Brief Summary

The study is a combined Phase-I like (safety) and Phase-II like (efficacy) double blind randomized placebo controlled trial. The objective is to investigate whether the combination of AG and Rg3-enriched Korean Red ginseng added to conventional medical treatment are effective and safe in the long-term management of high blood pressure while managing type 2 diabetes. Eighty-five subjects with type 2 diabetes and concomitant high blood pressure (key inclusion criteria: HbA1c ≥ 6.5%- ≤ 8.0%) will be recruited for the study.
