It prefers light (sandy), medium (loamy) and heavy (clay) soils. Clinical trials for relieving the main symptoms of hypertension were conducted, with a dose of 1.0-10.0 grams daily of the pure compound (five active ingredients). Normopress Capsules (250 mg/capsule, 0.5-2.0 grams daily) containing methyldopa were prescribed as a comparison. The results showed high effective rates (〉80%) for types of convulsions, including those that occur with tetanus, epilepsy, stroke, and headaches. In support of treating allergies, it alleviated headaches and general fatigue. It was helpful in clearing the heavy, congested feeling in the head described as the brain fag that accompanies allergies. It treated neurasthenia - weakness, nervous exhaustion and difficult concentrating. The necessity of Gastrodia elata cultivation to solve the rapid exhaustion of resourses was pointed out.展开更多

METHODS:Forty-five patients were studied:fifteen were randomized to PEG-IFN plus ribavirin(PR),16 to PEGIFN plus ketoprofen and 14 to PR and ketoprofen.Themolecular study of IFN-dependent signal transduction was conducted in 9 patients from each group. RESULTS:The combination of ketoprofen and PEG- IFN with or without ribavirin was safe and well tolerated.An early activation of STAT1 was observed in ke-toprofen-treated patients,but this activation was less sustained over time.Conversely,ketoprofen plus PEG- IFN and ribavirin induced an early and sustained increase of 2'-5'OAS transcription starting 24 h after the first dose until the 36th wk.These data are consistent with the clinical results,showing a better sustained virological response and a lower relapse rate in patients receiving ketoprofen plus PEG-IFN and ribavirin. CONCLUSION:The addition of ketoprofen to the standard therapy of chronic hepatitis C should be explored in larger randomized clinical studies.展开更多

He has been working in clinical evaluation and pharmacological evaluation for rheumatoid arthritis with integrative medicine approaches in CACMS for more than 20 years. During that period, he went to the Cell Biology Laboratory, Ohio State University, USA, from July 1990 to October 1991 and the Lurid University of Sweden from July 1995 to October 1996 for further study.展开更多

It is a deciduous shrub native to European, Mediterranean, and Central Asian countries. V. agnus castus has a long tradition as a herbal remedy and was used in ancient times not only as an anaphrodisiac but also against diverse disturbances of the female genital system. The major constituents in V. agnus-castus are flavonoids, essential oils, diterpenes, and glycosides. The flavonoids (casticin, quercetagetin, and isovitexin) have been shown in vitro to affect estrogen receptors. V. agnus-castus could be used to treat acne, digestive complaints, menstrual irregularities, premen- strual syndrome (PMS), mastalgia, and infertility, and also for lactation support. Although V. agnus-castus has been used for centuries and enjoys wide support from practitioners and the general public for many gynecological complaints, few clinical studies support its documented uses. The presence of phytochemical and pharmacological activities has proved that the plant has a leading capacity for the development of new good efficacy drug in future.展开更多
