Anti-hypertensive effect of Korean Red Ginseng by enrichment of ginsenoside Rg3 and arginine-fructose

Ginsenoside Rg3 and arginine-fructose (Arg-Fru) are known as the hypotensive compounds of Panax ginseng, however, their efficacy on antihypertension has not been reported yet to our best knowledge. Thus, hypotensive components-enriched fraction of red ginseng (HCEF-RG) was prepared from fine root concentrate (FR) and their antihypertensive effects were investigated in spontaneously hypertensive rats (SHR).

Water-soluble ginseng oligosaccharides protect against scopolamine-induced cognitive impairment by functioning as an anti-neuroinflammatory agent

Panax ginseng roots have been used in Oriental traditional medicine for human health. Its main active components, such as saponins and polysaccharides, have been widely evaluated for treatment of diseases, but the secondary active components, such as oligosaccharides, were rarely studied. This study aimed to assess the impact of water-soluble ginseng oligosaccharides (WGOS), which are isolated from warm-water extract of Panax ginseng roots and its components were confirmed, on scopolamine-induced cognitive impairment in mice and its anti-neuroinflammatory mechanisms.

Role of microRNA-520h in 20(R)-ginsenoside-Rg3-mediated angiosuppression

Ginsenoside-Rg3, the pharmacologically active component of red ginseng, has been found to inhibit tumor growth, invasion, metastasis, and angiogenesis in various cancer models. Previously, we found that 20(R)-ginsenoside-Rg3 (Rg3) could inhibit angiogenesis. Since microRNAs (miRNAs) have been shown to affect many biological processes, they might play an important role in ginsenoside-mediated angiomodulation. In this study, we examined the underlying mechanisms of Rg3-induced angiosuppression through modulating miRNA expression.

Black ginseng extracts ameliorates hypercholesterolemia in rats

Ginseng (Panax ginseng Meyer) is a well characterized medicinal herb listed in the classic oriental herbal dictionary as “Shin-nong-bon-cho-kyung”. Ginseng bears diverse pharmacologic and therapeutic properties. Black ginseng (BG, Ginseng Radix Nigra) is produced by repeatedly steaming fresh ginseng nine times. Studies of BG have shown that prolonged heat-treatment enhances the antioxidant activity with increased radical scavenging activity. Several recent studies have showed the effects of black ginseng on increased lipid profiles in mice.

Protective effect of Korean Red Ginseng against chemotherapeutic drug induced premature catagen development assessed with human hair follicle organ culture model

Chemotherapy-induced alopecia (CIA) is one of the most distressing side effects for patients undergoing chemotherapy. This study evaluated the protective effect of Korean Red Ginseng (KRG) on CIA in a well-established in vitro human hair follicle organ culture model as it occurs in vivo.
