Widely cultivated, Korean ginseng is used as a natural restorative, and valued for its adaptogenic properties. An adaptogen is supposed to help the body adapt to internal and external stressors and prevent stress induced damage and illnesses .Herbal practitioners define adaptogens as normalizers but adaptogen has no medical definition.. People use ginseng to increase their endurance and stamina, to fight off stress, to recuperate from a debilitating illness, to fight fatigue and to enhance their performance-physical, mental and even sexual. Ginseng is therefore sometimes used as an aphrodisiac. Ginseng extracts have been shown to have antioxidant activity, and to protect against radiation damage . European studies have shown that ginseng increases reaction times, alertness, concentration, and enhances coordination .
Contraindications & Precautions
Should not be used by persons with hypoglycaemia, insulin dependent diabetes, high blood pressure or heart disorders, unless approved by their physician.
Adverse Side Effects:
May cause nervousness, increased blood pressure, irritability in high doses. See Caution. Ginseng and /or adulterants have estrogenic activity and may cause vaginal bleeding and mastalgia [breast soreness] and patients with estrogen dependent malignancies may need to avoid ginseng.
Patients on anticoagulants e.g coumadin should avoid ginseng because ginseng is known to increase or decrease blood coagulation. Ginseng has potential to cause hypoglycaemia , because some components of ginseng can elevate plasma insulin levels. Therefore, diabetics who take ginseng must have their blood sugars monitored closely .
250 mg soft gel capsules.
500 mg per day of extract.
The main active ingredients of ginseng are the more than 20 saponin triterpenoid glycosides called ginsenosides or panaxosides. These range from Rb 1 group of ginsenoside (sedative and metabolic effects) to Rg 1 group (more arousing and stimulating). Rb1 Ginsenosides also have CNS depressant activity, weak anti-inflammatory activity, and increase bowel motility, as well as have some anti-pyretic, anti-convulsant and analgesic properties. The Rg1 ginsenosides have weak CNS stimulating properties, and protect against fatigue, as well as increase motor activity. There are no apparent major differences between American Ginseng & Oriental Ginseng. Siberian Ginseng is a different plant (Eleutherococcus Senticoccus), which has differing properties, and should not be confused with Panax Ginseng.
