Valeriana officinalis is an important medicinal herb commonly found in Kashmir valley. This study forms an important preliminary step for in-vitro micro propagation of V. officinalis from breaking the seed dormancy, inducing rapid seed germination and its subsequent micro propagation. We investigated the influence of pretreatment of V. officinalis seeds with reduced temperature and light on see...

Plant remedies, despite their innocuity reputation, are implicated in adverse events. The present review focuses on 30 popular herbs which are associated with severe and sometimes fatal hepatotoxicity: Actaea racemosa, Aloe barbadensis, Atractylis gummifera, Callilepsis laureola, Camellia sinensis, Centella asiatica, Chelidonium majus, Ephedra sinica, Garcinia cambogia, Hypericum perforatum, La...

Roots of the medicinal plant Valeriana officinalis are well-studied for their various biological activities. We applied genetically transformed V. officinalis root biomass to exert control of Physarum polycephalum, an amoeba-based emergent computing substrate. The plasmodial stage of the P. polycephalum life cycle constitutes a single, multinucleate cell visible by unaided eye. The plasmodium m...

The composition of the essential oil extracted from Valeriana hardwickii Wall. roots growing wild in Talle Valley of Arunachal Pradesh, Eastern Himalaya was analyzed by capillary GC and GC/MS.
