Panax Ginseng is one of the most widely used herbal medicines and is reported to have a wide range of therapeutic and pharmacological applications. Ginseng may also be potentially valuable in treating cardiovascular diseases. Research concerning cardiovascular disease is focusing on purified individual ginsenoside constituents of ginseng to reveal specific mechanisms instead of using whole ginseng extracts. One of the most commonly used and researched of the ginseng is Panax ginseng, also called Asian or Korean ginseng. The main active components of Panax ginseng are ginsenosides, which have been shown to have a variety of beneficial effects, including anti-inflammatory, antioxidant, and anticancer effects. Results of clinical research studies demonstrate that Panax ginseng may improve psychologic function, immune function, and conditions associated with diabetes.
Uses & Health benefits of Panax Ginseng
Erectile Dysfunction - Research has shown that ginseng may be a useful alternative for the treatment of erectile dysfunction (ED) in men (21, 22). It seems that compounds in it may protect against oxidative stress in blood vessels and tissues in the penis and help restore normal function (23, 24). Additionally, studies have shown that ginseng may promote the production of nitric oxide, a compound that improves muscle relaxation in the penis and increases blood circulation (24, 25). One study found that men treated with Korean red ginseng had a 60% improvement in ED symptoms, compared to 30% improvement produced by a medication used to treat ED (26). Moreover, another study showed that 86 men with ED had significant improvements in erectile function and overall satisfaction after taking 1,000 mg of aged ginseng extract for 8 weeks (27). However, more studies are needed to draw definite conclusions about the effects of ginseng on ED (24).
- Ginseng has beneficial antioxidant and anti-inflammatory properties (4). Some test-tube studies have shown that ginseng extracts and ginseng side compounds could inhibit inflammation and increase antioxidant capacity in cells (5, 6). For example, one test-tube study found that Korean red ginseng extract reduced inflammation and improved antioxidant activity is skin cells from people with eczema (7). The results are promising in humans, as well. One study investigated the effects of having 18 young male athletes take 2 grams of Korean red ginseng extract three times per day for seven days. The men then had levels of certain inflammatory markers tested after performing an exercise test. These levels were significantly lower than in the placebo group, lasting for up to 72 hours after testing (8). However, it should be noted that the placebo group got a different medicinal herb, so these results should be taken with a grain of salt and more studies are needed. Lastly, a larger study followed 71 postmenopausal women who took 3 grams of red ginseng or a placebo daily for 12 weeks. Antioxidant activity and oxidative stress markers were then measured.
- Work as an Anti-inflammatory Agent - Inflammation is a physiological response to various stimuli such as invading pathogens, irritants, and tissue injury, and can be classified as acute or chronic . In general, an acute inflammatory response has a rapid onset with short duration time and is characterized by a rapid movement of plasma proteins and leukocytes to the injured tissues . Although the acute response is a protective attempt to remove stimuli and to initiate the healing process, sustained inflammation may lead to detrimental, pathologic consequences on host . Such chronic inflammatory responses may result in significant tissue damages and develop to autoimmune diseases .
- Pain - There have been reports on pain-relieving effects of P. ginseng . Reported that ginsenosides could regulate the pain-related behavior of mice with capsaicin-induced pain in a dose-dependent manner. Lee et al. Demonstrated analgesic and anti-inflammatory effects of the fraction of P. ginseng in inflammatory pain mice models. Wang et al. Showed that glycoproteins extracted from P. ginseng exhibited a dose-dependent analgesic effect in mice by conducting acetic acid-induced writhing and hot-plate. Recently, a study also showed analgesic effect of P. ginseng in neuropathic pain animal models
- Anti-bacterial activity - For successful establishment of bacterial infections, it is necessary to have adhesion to host cells, colonization of tissues, and in certain cases, cellular invasion followed by intracellular multiplication, dissemination to other tissues, or persistence. In general, bacterial adhesion is mediated by certain interactions between adhesin from bacteria and carbohydrates on the surface of host cells. Studies have shown that ginseng polysaccharides could interact with microbes, interrupt microbial adhesion to host cells, and block the initiation of infectious disease.
- Anti-viral activity - Influenza virus, commonly referred to as the flu, can be influenced by RGE. After intranasal administration of ginseng extract with influenza virus A/PR8, significant increases in IgA as well as total IgG were observed in blood, lung, vaginal lavage, and fecal extract in mice. The increase in total IgG was comparable to that observed in the aluminium hydroxide or cholera toxin-adjuvant group. In addition, all serum IgG subtypes such as IgG1, IgG2a, IgG2b, and IgG3 antibodies were all augmented. Simultaneously, virus neutralization activity, cytokine production, body weight changes, and survival rates were all improved by ginseng treatment indicating that ginseng extract well-executes immunoregulatory function as an adjuvant.
- Parkinson's disease - Several studies have recently reported that P. ginseng has a wide range of actions in the central nervous system, with promising effects on Parkinson's disease. Demonstrated neuroprotective effects of the P. ginseng extract. It significantly reduced dopaminergic cell loss, preventing the development of locomotor deficits in chronic Parkinson's disease model animals. Hu et al. Demonstrated that the water extract of P. ginseng has significant protective effects against parkinsonism-inducing cytotoxic agents, such as 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine and its active metabolite 1-methyl-4-phenylpyridinium, in mice. It increased the Bax/Bcl-2 ratio, decreased cell death, promoted the release of cytochrome C, and suppressed the overproduction of reactive oxygen species.
- Cardiovascular effects - P. ginseng also produces numerous effects on the cardiovascular system . There have been studies suggesting the efficacy of P. ginseng on hypertension . It is known that P. ginsengregulates blood pressure to normal and thereby helps to elevate low blood pressure and to lower high blood pressure . It was reported that the effect of regulating high blood pressure is mediated by promoting vascular endothelial cell-derived nitric oxide secretion
- Anti Aging Property - Recent studies found a close relationship between angiogenesis and P. ginseng. P. ginseng and its ginsenosides reportedly modulate multiple steps of angiogenesis, such as inhibiting endothelial cell proliferation, formation of capillary tube, and vascular endothelial growth factor (VEGF)-induced chemoinvasion . According to Choi et al. Korean Red Ginseng extracts efficiently decrease several angiogenic factors such as IL-8, hypoxia inducible factor-1a, VEGF, IL-6, and matrix metalloproteinases, implying the underlying mechanism of anti-angiogenesis.
