Many patients with amyotrophic lateral sclerosis (ALS; motor neuron disease) use natural or traditional therapies of unproven benefit. One such therapy is ginseng root. However, in some other disease models, ginseng has proven efficacious. Ginseng improves learning and memory in rats, and reduces neuronal death following transient cerebral ischemia. These effects of ginseng have been related to increases in the expression of nerve growth factor and its high affinity receptor in the rat brain, and antioxidant actions, inter alia. Since such actions could be beneficial in ALS as well, we studied the effect of ginseng (Panax quinquefolium), 40 and 80 mg/Kg, in B6SJL-TgN(SOD1-G93A)1Gur transgenic mice. The ginseng was given in drinking water, from age 30d onwards. We measured the time to onset of signs of motor impairment, and survival. There was no difference between the two ginseng groups (n=6, 6) in either measure. However, compared to controls (n=13), there was a prolongation in onset of signs (116d vs. 94d, P<0.001), and survival (139d vs. 132d, P<0.05). These experiments lend support to the use of ginseng root in ALS. Future experiments using this model could examine for symptomatic effects of ginseng, measure the effect of specific ginsenosides (which differ between ginseng species), and elucidate their mechanisms of action.

Ginseng, the root of the Panax ginseng, has been a popular and widely-used traditional herbal medicine in Korea, China, and Japan for thousands of years. Now it has become popular as a functional health food and is used globally as a natural medicine. Evidence is accumulating in the literature on the physiological and pharmacological effects of P. ginseng on neurodegenerative diseases. Possible ginseng- or ginsenosides-mediated neuroprotective mechanisms mainly involve maintaining homeostasis, and anti-inflammatory, anti-oxidant, anti-apoptotic, and immune-stimulatory activities. This review considers publications dealing with the various actions of P. ginseng that are indicative of possible neurotherapeutic efficacies in neurodegenerative diseases and neurological disorders such as Parkinson's disease, Alzheimer's disease, Huntington's disease, and amyotrophic lateral sclerosis and multiple sclerosis.

Cyclophosphamide (CP), a chemotherapeutic agent, is restricted due to its side effects, especially hepatotoxicity. Ginseng has often been clinically used with CP in China, but whether and how ginseng reduces the hepatotoxicity is unknown. In this study, the hepatoprotective effects and mechanisms under the combined usage were investigated. It was found that ginseng could ameliorate CP-induced elevations of ALP, ALT, ALS, MDA and hepatic deterioration, enhance antioxidant enzymes' activities and GSH's level. Metabolomics study revealed that 33 endogenous metabolites were changed by CP, 19 of which were reversed when ginseng was co-administrated via two main pathways, i.e., GSH metabolism and primary bile acids synthesis. Furthermore, ginseng could induce expression of GCLC, GCLM, GS and GST, which associate with the disposition of GSH, and expression of FXR, CYP7A1, NTCP and MRP 3, which play important roles in the synthesis and transport of bile acids. In addition, NRF 2, one of regulatory elements on the expression of GCLC, GCLM, GS, GST, NTCP and MRP3, was up-regulated when ginseng was co-administrated. In conclusion, ginseng could alleviate CP-induced hepatotoxicity via modulating the disordered homeostasis of GSH and bile acid, which might be mediated by inducing the expression of NRF 2 in liver.

Despite the increasing use of ginseng pharmacopuncture in clinical practice, evidence of its physiological effects, safety, and clinical outcomes is insufficient. The purpose of this review is to summarize previous studies and suggest future challenges for the clinical use of ginseng pharmacopuncture. We systematically searched clinical and animal studies that applied ginseng pharmacopuncture and reviewed the manufacturing processes of ginseng pharmacopuncture solution, safety, physiological responses, and clinical effects. Intravenous or point injection of the ginseng pharmacopuncture solution made by distillation extraction has been commonly used in studies. Ginseng pharmacopuncture does not show any toxicity in animals and humans, while it influenced the heart rate variability, pulse wave velocity, and protein synthesis in human subjects. In 25 case reports, patients with cancer, amyotrophic lateral sclerosis, skin wrinkles, and allergic rhinitis showed significant improvement of clinical outcomes. We found that more evidence is necessary to conclude that ginseng pharmacopuncture is safe and effective. First, the pharmacopuncture manufacturing process should be standardized on the basis of the safety and efficacy tests. Moreover, studies on the quantitative quality of the components of the solution and on the clinical comparison of various injection methods are required to improve clinical outcomes in the future.
