POSSIBLY EFFECTIVE

• Upper respiratory tract infection (URTI). Oral American ginseng seems to prevent the incidence of URTIs in some people. Details: Some evidence shows that taking a specific American ginseng extract called CVT-E002 (Cold-FX, Afexa Life Sciences) 200-400 mg twice daily over a 3-64 month period during influenza season might modestly decrease the risk of developing symptoms of a URTI such as the common cold or flu in adults (11351,13192,14345,91275). This extract also seems to reduce symptom severity and duration of symptoms when infections do occur (13192,14345,91275). The extract might not reduce the chance of getting the first cold of a season, but it seems to reduce the risk of getting repeat colds in a season (13192). Additional evidence shows that, in people aged 65 years and older, treatment with the extract for 3-4 months, in addition to influenza vaccination at 4 weeks, is necessary before there is any significant reduction in the risk of developing a respiratory tract infection (14345). One small clinical study shows that taking the extract 200 mg twice daily orally over a 12-week period during influenza season reduces the risk of laboratory confirmed influenza or influenza and respiratory syncytial virus (RSV) infections. However, it does not seem to reduce the appearance of influenza symptoms, symptom severity, or symptom duration in these patients (11351). This same extract does not appear to prevent respiratory infections in patients who are immunocompromised. In one clinical trial, taking this extract 200 mg twice daily for 3 months did not reduce the risk of developing an acute respiratory infection, the number of days of cold symptoms, or the need for use of antibiotics when compared with placebo in patients with chronic lymphocytic leukemia (29998). Preliminary clinical research in children 3-12 years of age shows that taking the same extract 13-26 mg/kg once on the day of URTI onset, then 8.5-17 mg/kg once on the next day, then 4.5-9 mg/kg once on day three does not reduce the severity or duration of symptoms when compared with placebo. However, this study was designed to evaluate the safety and tolerability of this extract in children; therefore, it was not adequately powered to evaluate effectiveness (22365).

INSUFFICIENT RELIABLE EVIDENCE to RATE

• Anemia of chronic disease. Although there has been interest in using oral American ginseng for anemia of chronic disease, there is insufficient reliable information about the clinical effects of American ginseng for this condition.
• Antiretroviral-induced insulin resistance. It is unclear if oral American ginseng is beneficial for antiretroviral-induced insulin resistance. Details: Preliminary clinical research in healthy volunteers shows that taking capsules containing ground American ginseng root 1 gram three times daily for 14 days along with the HIV protease inhibitor indinavir does not reduce indinavir-induced insulin resistance when compared to baseline (89401).
• Athletic performance. Early research shows that oral American ginseng does not seem to be beneficial for athletic performance. Details: Preliminary clinical research shows that taking American ginseng extract 8 mg/kg or 16 mg/kg daily (average daily dose 618-1235 mg) for one week does not improve exertion, time to exhaustion, heart rate, or maximal oxygen consumption during bicycle testing when compared with placebo (4236). Other preliminary clinical research in physically active male college students shows that taking American ginseng 1600 mg daily for 4 weeks does not enhance workout capacity when compared with placebo (14804).
• Attention deficit-hyperactivity disorder (ADHD). Oral American ginseng has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research shows that taking a specific combination product (AD-fX, Afexa Life Sciences) containing American ginseng extract plus ginkgo leaf extract may modestly improve ADHD symptoms such as anxiety, hyperactivity, and impulsivity in children aged 3-17 years when compared with baseline (8235). It is not clear if this effect is due to American ginseng, ginkgo, or the combination. Additionally, the validity of this finding is limited by the lack of a comparator group.
• Breast cancer. It is unclear if oral American ginseng is beneficial for breast cancer survival. Details: Population research in China suggests that breast cancer patients who regularly take any form of ginseng, including either American ginseng or Panax ginseng, have higher quality of life scores and have a lower risk of overall mortality, breast cancer-related mortality, and breast cancer recurrence compared to patients who do not take ginseng (14466). However, ginseng users were also significantly more likely to have been treated with tamoxifen.
• Cancer-related fatigue. Evidence for the use of oral American ginseng for cancer-related fatigue is conflicting. Details: Two clinical trials show that taking American ginseng 750-2000 mg in 1-2 divided doses daily for 8 weeks does not reduce cancer-related fatigue when compared with placebo (22370,104131). However, another clinical trial shows that taking American ginseng 2000 mg in two divided doses daily for 8 weeks reduces cancer-related fatigue scores by 51% after 8 weeks, compared to only 25% in those taking placebo (29996). These differing findings may be due to the instrument used to measure fatigue. The initial studies used the Brief Fatigue Inventory, whereas the positive study used the Multidimensional Fatigue Symptom Inventory-Short Form (MFSI-SF). Additionally, treatment for a shorter duration of only 4 weeks does not appear to be effective (22370,29996,104131).
• Cardiovascular disease (CVD). Although there has been interest in using oral American ginseng for CVD, there is insufficient reliable information about the clinical effects of American ginseng for this condition.
• Cognitive function. It is unclear if oral American ginseng is beneficial for cognitive function. Details: Clinical research shows that a single dose of a specific American ginseng extract (Cereboost, Naturex) 100-400 mg, taken 1-6 hours prior to cognitive testing, improves short-term working memory performance and may improve reaction time accuracy when compared with placebo in healthy young adults (22367). Other clinical research in healthy adults shows that taking the same specific American ginseng extract, standardized to contain 10% to 12% ginsenosides, as 200 mg orally daily for 14 days modestly improves memory and mental fatigue scores when compared with placebo (109518). American ginseng has also been studied in combination with other ingredients. Taking a single dose of a product containing American ginseng (Cereboost) 100 mg, bacopa 300 mg, and coffee fruit extract 100 mg modestly improves some, but not all, measures of working memory and attention after 45 minutes when compared with placebo (103375).
• Diabetes. It is unclear if oral American ginseng is beneficial for diabetes. Details: Two small clinical trials show that taking American ginseng 3 grams orally, up to two hours before a meal, can significantly reduce postprandial glucose levels in patients with type 2 diabetes when compared with placebo (1018,6461). However, doses greater than 3 grams do not seem to offer any additional benefit (6461). In addition, the postprandial glucose lowering effect of American ginseng may differ among preparations due to variations in the concentration of ginsenosides (9732). American ginseng has also been studied in combination with other ingredients. Clinical research in patients with type 2 diabetes shows that taking American ginseng 1500 mg and Panax ginseng 750 mg, enriched to contain 30% total ginsenosides, orally daily for 12 weeks reduces glycated hemoglobin by 0.35% when compared with placebo. Taking this combination also reduces systolic, but not diastolic, blood pressure by about 4 mmHg when compared with placebo (107745). It is unclear if this effect is due American ginseng, Panax ginseng, or the combination.
• Epilepsy. Although there has been interest in using oral American ginseng for epilepsy, there is insufficient reliable information about the clinical effects of American ginseng for this condition.
• Headache. Although there has been interest in using oral American ginseng for headaches, there is insufficient reliable information about the clinical effects of American ginseng for this purpose.
• HIV/AIDS. Although there has been interest in using oral American ginseng for HIV/AIDS, there is insufficient reliable information about the clinical effects of American ginseng for this condition.
• Hypertension. Evidence on the use of oral American ginseng for hypertension is conflicting. Details: Some clinical research shows that taking American ginseng 1500 mg twice daily for 12 weeks does not reduce blood pressure when compared with placebo in patients with hypertension (22368,22369). However, other clinical research shows that taking American ginseng extract 1000 mg three times daily for 12 weeks lowers systolic blood pressure by 12% when compared with baseline in patients with type 2 diabetes and hypertension (29999). In a similar study in patients with type 2 diabetes and hypertension, American ginseng extract 500 mg in combination with Panax ginseng extract 250 mg three times daily for 12 weeks, providing 30% total ginsenosides daily, reduces central systolic blood pressure by about 5 mmHg, but not diastolic blood pressure, when compared with placebo (103046). These differing results may be due to the higher amount of total ginsenosides provided in the latter study.
• Menopausal symptoms. Oral American ginseng has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research during pre- and post-menopause shows that taking a specific combination product (Phyto-Female Complex, SupHerb) containing black cohosh root extract 100 mg, dong quai root extract 75 mg, milk thistle extract 75 mg, red clover flower extract 50 mg, American ginseng root extract 50 mg, and vitex agnus-castus fruit extract 50 mg twice daily for 12 weeks improves sleep quality and reduces menopausal symptoms, including the number and intensity of hot flashes and the number of night sweats, when compared with placebo (19552). However, it is unclear whether these effects are due to American ginseng, other ingredients, or the combination.
• Schizophrenia. It is unclear if oral American ginseng is beneficial for schizophrenia. Details: Preliminary clinical research in adults with schizophrenia who are taking antipsychotics shows that taking a specific American ginseng extract (HT1001, Afexa Life Sciences) 100 mg twice daily for 4 weeks modestly increases visual working memory score when compared with placebo. This treatment also reduces physical symptoms associated with antipsychotic use, such as abnormal gait or muscle rigidity. However, it does not appear to improve other clinical symptoms or parameters related to cognitive function, such as verbal working memory, sustained attention, verbal function, or immediate or delayed auditory memory, when compared with placebo (29997).
• Ulcerative colitis. Although there has been interest in using oral American ginseng for ulcerative colitis, there is insufficient reliable information about the clinical effects of American ginseng for this condition. More evidence is needed to rate American ginseng for these uses.
