Introduction: Kappaphycus alvarezii (K. alvarezii) or locally known as red seaweed, was claimed to improve health and well-being. The goal of this study is to investigate how K. alvarezii affects blood pressure (BP), total cholesterol (TC), ACE, and antioxidant activities in rats with hyperten-sion and hypercholesterolemia (HTN-HC). Methods: Induct...

Many herbs from the Zingiberaceae family are widely used as raw materials in herbal products. Some of them have a similar colour for their rhizomes and are quite hard to distinguish from each other, so it is possible to misidentify one for the other. Therefore, it is necessary to find a rapid and reliable method for discrimination of Zingiberaceae-...
