Is ginseng free from adverse effects?
Xie, Jing-Tian,Mehendale, Sangeeta R.,Maleckar, Spring A.,Yuan, Chun-Su Kyung Hee Oriental Medicine Research Center 2002 Oriental pharmacy and experimental medicine Vol.2 No.2
Ginseng is a perennial herb widely used in China, Japan, and Korea. It is also one of the most commonly used herbal medicines in the U.S. Although it is generally considered safe to use, adverse effects associated with ginseng use have been reported. Inappropriate ginseng use, such as high dose administration, may cause insomnia, headaches, diarrhea, as well as cardiovascular and endocrine disorders. Other factors that may contribute to adverse effects of ginseng include the variety of ginseng species, variability in commercial ginseng preparations, and potential ginseng-drug interactions. To minimize adverse effects of ginseng, consumers should be advised to use it appropriately, and the herbal industry should try to provide standardized ginseng preparations.

Aging care is critical. Projections for 2020 indicate that India’s older population will comprise 6.57% of the overall population. The best-known newly developed technologies must be provided to the older population. Non-governmental organizations and private institutions are increasingly providing more door-to-door guidance and help. This study evaluated the impact of the National Programme for Health Care of the Elderly (NPHCE) in India and analyzed its achievements and challenges. The program’s key strategies include providing preventive and promotional care and sickness management, empowering geriatric services, and guaranteeing optimal rehabilitation. The NPHCE is an excellent project for caring for a rapidly aging population. This study described the existing programs and schemes related to older people in India, with a focus on the NPHCE and an analysis of the program’s achievements and challenges.

In this study, we evaluated the antiproliferative effects of Panax notoginseng, ginsenoside Rb1, and notoginsenoside R1 in the human breast carcinoma MCF-7 cell line. Our results indicated that both Panax notoginseng radix extract (NRE) and Panax notoginseng rhizoma extract (NRhE) possess significant antiproliferative activities in MCF-7 cells. Compared to control group (100%), at the concentrations of 0.05, 0.5, and 1.0 mg/ml NRE, cell growth was concentration-dependently reduced to 81.0 ${\pm}$ 6.1 (P < 0.01), 34.2 ${\pm}$ 4.8 (P < 0.001), and 19.3 ${\pm}$ 1.9 (P < 0.001), respectively. Similar results with NRhE at concentrations of 0.5 and 1.0 mg/ml were obtained in these MCF-7 cells. To identify the responsible chemical constituent, we tested the antiproliferation effects of two representative saponins, ginsenoside Rb1 and notoginsenoside R1, on the MCF-7 cells. The data showed that ginsenoside Rb1 was endowed with antiproliferative properties, while notoginsenoside R1 did not have an inhibitory effect in the concentrations tested. Our studies provided evidence that Panax notoginseng extracts and ginsenoside Rb1 may be beneficial, as adjuvants, in the treatment of human breast carcinoma.

Previous studies showed that Asian ginseng, Panax ginseng C.A. Meyer, may have anti-cancer properties. However, there is limited data exploring the use of Asian ginseng as an adjuvant to chemotherapy, and minimal mechanistic studies related to their possible synergistic activities. In this study, the content of 8 ginsenosides, Rb1, Rb2, Rb3, Rc, Rd, Re, Rg1 and Rg3, in the extracts of white ginseng (WG) and red ginseng (RG) were determined by HPLC. Using HCT-116 human colorectal cancer cells, we compared the efficacy of WG and RG. We evaluated the synergy between ginseng and 5-fluorouracil (5-FU), and explored the mechanism of their anti-proliferative effects. As single extract, WG or RG used at concentrations of 0.1, 0.2 and 0.3 mg/mL, inhibited HCT-116 cell proliferation in a concentration-related manner. WG at 0.2 mg/mL did not show obvious synergy with 5-FU co-treatment, while RG at 0.2 and 0.3 mg/mL significantly enhanced the anti-proliferative effects of 5-FU at concentrations of 10, 50 and 100 μM (P < 0.05). Using flow cytometric assay, RG 0.3 mg/mL did not affect cancer cell apoptotic induction activity. However, the RG induced cell cycle arrest in the G1 phase, while 5-FU arrested the cell in the S phase. Different ginsenoside profiles are responsible for the observed differences in pharmacological effects. The effects of 8 ginsenosides on HCT-116 cells were assayed. Rd and Rg3 showed positive anti-proliferative effect. Our data suggested a potential for RG as an adjuvant therapy in the treatment of colorectal cancer, via a synergistic action.

Purpose The pharmacological activities, notably the anticancer properties, of bioactive constituents from fresh American ginseng berry have not yet been well studied. In this study, we investigated the antiproliferative effects of fresh American ginseng berry extract (AGBE) and its representative triterpenoid glycosides using the human colorectal cancer cell line SW480. Materials and Methods Using high performance liquid chromatography (HPLC), the contents of 8 ginsenosides in AGBE were determined. The cell growth inhibitory effects of AGBE and three triterpenoid glycosides (ginsenosides Rb3, Re, and Rg3) were evaluated by proliferation assay and 3H-thymidine incorporation assay. Cell cycle and apoptotic effects were analyzed by using flow cytometry after staining with propidium iodide and annexin V. Results HPLC analysis data showed that AGBE has a distinct ginsenoside profile. AGBE inhibited SW480 cell growth significantly in a time-dependent (24-96 hours) and concentration-dependent (0.1-1.0 mg/mL) manner. Ginsenosides Rb3, Re, and Rg3 also possess significant antiproliferative activities on SW480 cells. 3H-thymidine incorporation assay indicated that AGBE and ginsenosides Rb3, Re, and Rg3 might inhibit the transferring and duplication of DNA in SW480 cells. Flow cytometric assay data suggested that AGBE arrested SW480 cells in S and G2/M phases, and significantly induced cell apoptosis. Conclusion AGBE and ginsenosides Rb3, Re, and Rg3 possessed significant antiproliferative effects and induced changes of morphological appearance on SW480 cells. The mechanisms of the antiproliferation of AGBE and tested ginsenosides involved could be cell cycle arrest and induction of apoptosis.
