Core Tip

Core Tip: We have been searching for a natural agent capable of controlling diabetic conditions in patients with type 2 diabetes for years. We then came across “SX-fraction (SXF)”, isolated from maitake mushroom (Grifola frondorsa), with anti-diabetic and hypoglycemic activities. In this short review, we chronologically described several key studies of SXF such as animal studies using diabetic mice (to demonstrate anti-diabetic activity), limited clinical studies on volunteer patients with type 2 diabetes (to show hypoglycemic activity), and in vitro study using skeletal muscle cells (to elucidate the hypoglycemic mechanism). After all, SXF appears to be a natural, safe, effective agent for treatment of patients with type 2 diabetes, although more (clinical) studies are yet required for confirmation.
