About this study

Official title: A 60-Day Clinical Study to Evaluate Nutrilite Ginko Biloba Cistanche Tablets in Relieving the Symptoms of Chronic Fatigue Syndromes Compared to Negative Control

To evaluate the efficacy of Nutrilite® ginkgo biloba cistanche tablets in relieving the symptoms of chronic fatigue syndrome(CFS), the investigators randomly recruit189 subjects with CFS, aged 35-60 yrs. The relief of fatigue and improvement of sexual function are evaluated by World Health Organization Quality Of Life Brief (WHOQoL-Bref), Sexual Life Quality Questionnaire (SLQQ), chronic fatigue syndrome, symptoms of self-assessment at the baseline and the end of intervention. Subjects also underwent a blood test measuring the concentration of biochemical indicators. Cistanche is mainly used to strengthen the renal function, nourish essence and blood in the treatment of lumbar debility, impotence, infertility and muscles weakness, constipation. etc. The study is to test the hypothesis that consecutive 60-day intake of the study tablets can relieve the symptoms of CFS; according to the change of blood biology indicators, the investigators will also evaluate the association between the change of plasma outcome measures and chronic fatigue syndrome.

Read the detailed description

Chronic fatigue syndrome (CFS) is the common name for a group of significantly debilitating medical conditions characterized by persistent fatigue and other specific symptoms that lasts for a minimum of six months in adults. Symptoms of CFS include malaise after exertion; unrefreshing sleep, physical exhaustion, sore throat, headaches, widespread muscle and joint pain, and depression. The cause of CFS is unclear, but appears to result from a multiple factors. Generally, the onset of CFS is associated with psychological stress, endocrine and immune disorder, genetic factors, and viral infections the diagnostic criteria for CFS modified by Fukuda,etc.in 1994. Currently, there is no one common treatment for CFS. regularly used treatments include the medications which enhance immunity system and nutrition-balanced therapy, Cognitive behavioural therapy (CBT), , local physiotherapy, , and graded exercise therapy(GET).The main purposes of the treatments are to relieve CFS symptoms, improve the psychological condition and social function. According to the U.S. Centers for Disease Control and Prevention (CDC) , CFS will become one of the main diseases that affect human health.

Cistanche, is a desert plants in the family Orobanchaceae. It mainly grows in the sandy pastures of Inner Mongolia, Gansu and Xinjiang Province of China. The plants of the best quality is from Inner Mongolia. According to Traditional Chinese Medical theories, its nature and flavour is sweet, salty, warm, and goes into kidney, large intestine meridians. It is commonly used to invigorate the renal function, nourish essence and blood in the treatment of lumbar debility, impotence, infertility and muscles weakness, and regulates the intestinal tract environment such as dryness, and constipation. A clinical trial showed that Cistanche granules relieved kidney deficiency symptoms in 86.7% of the chronic fatigue syndrome patients, demonstrated a significant difference comparing post-intervention to baseline (P <0.01).

Ginko As recorded in the Yuan Herbal Classic by Lulu Zhang Feng in Qing Dynasty, ginkgo has functions of reducing phlegm, detoxification, insect killing, could cure scabies and gangrene tumors, acute mastitis ulceration disease, dental caries, infantile diarrhea, leukorrhea with reddish discharge, chronic stranguria with turbid discharge, emission enuresis disease.

In addition, ginkgo can inhibit various types of pathogenic bacteria. A clinical study (conducted by Wuhan Military General Hospital) of over 100 subjects with high cholesterol showed that ginkgo extract (guanxin ketones) has antihypertensive effect.

Germany, United Kingdom, France, USA and South Korea also used ginkgo leaves to produce drugs for treating cardiovascular and cerebrovascular diseases.

Ginkgo root, containing ginkgo lactone C, M, A, B, is sweet, warm, plain and nontoxic, and can be used to treat leucorrhea disease and emission.

A study about late Alzheimer disease found that ginkgo can improve vascular patency, thus has notable effect in anti-aging of brain function in elderly people, and enhancing memories.

Subjects with ginkgo juice supplement showed significant improvement in memory, attention and complex movements compared to the control group, patients who take ginkgo juice have significantly improved.
