Polygonum glabrum is being used in traditional and folklore medicine to treat pneumonia and jaundice. Plant roots are used in ayurvedic preparations to treat fever and colic. The leaves are used as diuretic agents and process vermifuge action. Plant decoction is also used in the treatment of Rheumatism. Besides having many uses and folklore claims, herbal medicines are to be thoroughly investigated for their toxicity also. Therefore this work is being carried out to examine the toxicity of the drug and established dose is safe to use in the clinical stage. The current research studied the acute and chronic toxicity of Polygonum glabrum root extract in rats. It is proved that there was no change in any parameter tested both in acute and chronic toxicity, which means the extract is safe and non-toxic at the dose of 2g/kg also.

We studied the immunohistochemical localization of abscisic acid (ABA), wheat germ agglutinin (WGA) and dehydrins in the roots of wheat seedlings (Triticum aestivum L.) during 24-epibrassinolide-pretreatment (EB-pretreatment) and PEG-induced dehydration. It was found coimmunolocalization of ABA, WGA and dehydrins in the cells of central cylinder of basal part untreated and EB-pretreated roots of wheat seedlings under normal conditions and under osmotic stress. Such mutual localization ABA and protective proteins, WGA and dehydrins, indicates the possible effect of their distribution in the tissues of EB-pretreated wheat roots during dehydration on the apoplastic barrier functioning, which apparently contributes to decrease the water loss under dehydration. Perhaps, the significant localization of ABA and wheat lectin in the metaxylem region enhances EB-induced transport of ABA and WGA from roots to shoots under stress. It can be assumed that brassinosteroids can serve as intermediates in the realization of the protective effect of WGA and wheat dehydrins during water deficit.
