Several clinical studies have shown that valerian is effective in the treatment of insomnia, most often by reducing sleep latency. A double-blind, placebo-controlled trial compared a 400-mg aqueous extract of valerian and a commercial valerian/hops preparation with placebo of encapsulated brown sugar. A total of 128 volunteers completed a subjective study evaluating the effects of single doses ...

Ever since the discovery of the element iodine by Courtois (1) in 1812 and the first clinical uses of this substance in the treatment of goiter by Prout (2) in 1816 and by Coindet (3) in 1820, almost continuous researches on the relationship of iodine to thyroid function have been in progress. The greatest obstacle in the way of these investigations has been the lack of a reliable method for th...

Essential oils of sixteen Chinese medicinal plants were screened for fumigant toxicity against Bemisia tabaci. The essential oil of Allium sativum exhibited the strongest fumigant activity against B. tabaci with an LC50 value of 0.11 μg/l followed by the essential oils of Agastache rugosa (LC50 = 7.08 μg/l), Illicium verum (LC50 = 8.61 μg/l), Chenopodium ambrosioides (LC50 = 8.80 μg/l), and Syz...

In order to investigate essential oils with biological activity from local wild plants, two valerianaceous species, Nardostachys chinensis and Valeriana officinalis, were screened for their antimicrobial and antioxidant activity. The essential oils were obtained from the roots and rhizomes of the two plants by hydro-distillation, and were analyzed for their chemical composition by gas chromatog...

Valeriana officinalis is a medicinal herb which produces a suite of compounds in its root tissue useful for treatment of anxiety and insomnia. The sesquiterpene components of the root extract, valerenic acid and valerena-1,10-diene, are thought to contribute to most of the observed anxiolytic of Valerian root preparations. However, valerenic acid and its biosynthetic intermediates are only prod...

A plasmodium of acellular slime mould Physarum polycephalum is a large single cell with many nuclei. Presented to a configuration of attracting and repelling stimuli a plasmodium optimizes its growth pattern and spans the attractants, while avoiding repellents, with efficient network of protoplasmic tubes. Such behaviour is interpreted as computation and the plasmodium as an amorphous growing b...
