Recent reports suggest that ginseng could regulate blood pressure (BP), but much controversy still remains. Therefore, we intended to assess the anti-hypertensive effect of several ginseng types frequently used in clinics. We also investigated the anti-hypertensive effect on Koreans and Chinese, and by the body type according to Sasang Constitution Medicine (SCM). Methods : The study subjects were recruited from mildly hypertensive patients who exhibited pre-hypertension (120/80 to 139/89 mmHg) and stage I hypertension (140/90 to 159/99 mmHg) in Korea and China. After assigning the subjects into a Korean, a Chinese, a red, and an American ginseng group by randomization, we prescribed ginseng at a dose of 4.5 g per day for 4 weeks. To assess the anti-hypertensive effect, we compared the mean of systolic and diastolic BP between before and after ginseng medication using a 24-hour ambulatory blood pressure monitor (24 hr ABPM).

We have reviewed the successful use of different chemical methods for the botanical authentication of 2,386 commercial herbal products, sold in 37 countries spread over six continents. The majority of the analyzed products were reported to be authentic (73%) but more than a quarter proved to be adulterated (27%).

  • Panax Ginseng
    Last updated on December 22, 2020 Cognitive Vitality Reports® are reports written by neuroscientists at the Alzheimer’s Drug Discovery Foundation (ADDF). These scientific reports include analysis of drugs, drugs-in- development, drug targets, supplements, nutraceuticals, food/drink, non-pharmacologic interventions, and risk factors. Neuroscientists evaluate the potential benefit (or harm) for brain health, as well as for age-related health concerns that can affect brain health (e.g., cardiovascular diseases, cancers, diabetes/metabolic syndrome). In addition, these reports include evaluation of safety data, from clinical trials if available, and from preclinical models. Panax Ginseng Evidence Summary Some studies have shown that ginseng improves cognitive functions and decreases mortality and cancer risk in humans; safe when taken alone, but some drug interactions are known. Neuroprotective Benefit: Numerous studies have reported cognitive benefit with ginseng in healthy people as well as in dementia patients, but the evidence remains inconclusive due to the lack of large, long-term well-designed trials. Aging and related health concerns: Ginseng intake is associated with lower risks for mortality and cancers; also, some benefits seen in Asian people with ischemic heart disease, diabetes, hypertension, hypercholesteremia, and fatigue. Safety: Numerous meta-analyses have reported that ginseng is generally safe when taken alone; however, ginseng interacts with several medications, and high doses may be associated with insomnia, tachyarrhythmias, hypertension, nervousness, and others. 1 Last updated on December 22, 2020 Availability: OTC. In clinical Dose: 200-400 mg/day Chemical formula: e.g., C42H72O14 trials, a standardized ginseng have been tested for (Ginsenoside Rg1); C54H92O23 extract called G115 is often cognitive benefit; higher (Ginsenoside Rb1) used.

The aim of the study is to compare the average content of ginsenosides from NZ-grown ginseng and its original native locations (China and Korea) grown ginseng. Ten batches of NZ-grown ginseng were extracted using 70% methanol and analyzed using LC-MS/MS. The average content of ginsenosides from China and Korea grown ginseng were obtained by collecting data from 30 and 17 publications featuring China and Korea grown ginseng, respectively. The average content of total ginsenosides in NZ-grown ginseng was 40.06 3.21 mg/g (n = 14), which showed significantly ± (p < 0.05) higher concentration than that of China grown ginseng (16.48 1.24 mg/g, n = 113) and ± Korea grown ginseng (21.05 1.57 mg/g, n = 106). For the individual ginsenosides, except for the ± ginsenosides Rb2, Rc, and Rd, ginsenosides Rb1, Re, Rf, and Rg1 from NZ-grown ginseng were 2.22, 2.91, 1.65, and 1.27 times higher than that of ginseng grown in China, respectively.

E-mail: [email protected] Z. Naturforsch. 59c, 39Ð42 (2004); received July 22, 2003 Essential oils from three of the eleven endemic New Zealand species of Pseudopanax, P. arboreus, P. discolor and P. lessonii, were found to have a fairly uniform composition which was different from that of the oils of Raukaua species that were formerly classified in the Pseudopanax genus. Oils of the three Pseudopanax species all contained significant propor- tions of viridiflorol and a closely related unidentified hydroazulene alcohol in common. In addition, the oil of P. arboreus contained bicyclogermacrene, linalool and long chain hy- drocarbons. The oil of P. discolor contained nerolidol in abundance (36.3%) together with linalool and epi-α-muurolol. The oil of P. lessonii contained a complex mixture of sesquiter- pene alcohols including epi-α-muurolol and a mixture of long chain hydrocarbons. Nerolidol and linalool provided the oil of P. discolor with a pleasant floral aroma, but the yield of oil was very low (0.01%).

Web of Science의 core col- lection에 수재된 전체 학술논문에서 인삼 논문이 차지하는 비중도 1970년 0.0008%, 1980 년 0.0044%, 1990년 0.101%, 2000년 0.0141%에서 2019년에는 0.0422%로 비약적으로 증가 하였다. 지난 24년간 출판된 인삼 연구논문 중 원보(노트 포함)는 7,099편, 리뷰는 286편이었다. 총 78개국 3,286개 기관에서 연구가 이루어졌으며, 1,274개 학술잡지에 논문이 수재되었다. 전체 논문 중 중국에서 연구된 논문이 40.3%로 가장 높았고, 대한민국에서 연구된 논문 이 34.7%로 한국과 중국의 연구가 전체의 75%를 차지하였다. 그 다음은 미국(6.0%), 일본 (4.1%), 캐나다(2.9%) 순이었다. 2013년까지는 한국에서 연구된 논문이 가장 많았으나 2014 년부터 중국에서 연구된 논문의 수가 더 많아졌다. 지난 24년간 인삼은 전세계에서 가장 많이 연구된 약용식물로 인삼 다음으로는 차(6,499편), 마늘(3,641편), 은행(2,590편), 생강 (1,945편) 순이었다. 주제어: 인삼, 연구논문의 수, web of science Abstract We conducted a comprehensive analysis of research papers on ginseng to provide an overview of global ginseng research. The qualitative and quantitative interpretation was carried out using collected data of Panax species and six other herbal plants from the Web of ScienceTM Core Collection.
