Abstract. Cognitive rehabilitation is an important area of neurological rehabilitation, which aims at the treatment of cognitive disorders due to acquired brain damage of different etiology, including stroke. Although the importance of cognitive rehabilitation for stroke survivors is well recognized, available cognitive treatments for neuropsychological disorders, such as spatial neglect, hemianopia, apraxia, and working memory, are overall still unsatisfactory. The growing body of evidence supporting the potential of the transcranial Electrical Stimulation (tES) as tool for interacting with neuroplasticity in the human brain, in turn for enhancing perceptual and cognitive functions, has obvious implications for the translation of this noninvasive brain stimulation technique into clinical settings, in particular for the development of tES as adjuvant tool for cognitive rehabilitation. The present review aims at presenting the current state of art concerning the use of tES for the improvement of post-stroke visual and cognitive deficits (except for aphasia and memory disorders), showing the therapeutic promises of this technique and offering some suggestions for the design of future clinical trials. Although this line of research is still in infancy, as compared to the progresses made in the last years in other neurorehabilitation domains, current findings appear very encouraging, supporting the development of tES for the treatment of post-stroke cognitive impairments.

The objective of the present study is to evaluate the quality of the marketed and self collected samples of Plumbago zeylanica L. roots on the standardization parameters. This study is planned mainly to confirm changes with quality of drug. Now a day’s more demand of herbal drugs for disease treatment, lack of knowledge of proper methodology and availability are promoting the practices of adulteration and substitution. Thus, the standardization of the plant crude drugs is necessary to maintain their therapeutic efficacy. Comparative studies were carried out to evaluate the standards of P. zeylanica L. with emphasis on organoleptic evaluation, physicochemical and phytochemical analysis. Samples were procured from local market and self collected to determine the qualitative and quantitative variations. The result indicates that self collected sample showed significant results with comparison to marketed sample.

Filipendula ulmaria (L.) Maxim. (Meadowsweet) is known in traditional medicine as anti-inflammatory, wound-healing,astringent and antibacterial remedy. However recent studies show that it also has neurotropic activity. In Russia meadowsweet flowers are used as crude herbal drugs (temporary pharmacopoeial monograph 42-1777-87), also leafs and herb are used in the traditional medicine. Objective of the study was to carry out comparative investigation of composition and content of major biologically active compounds (BAC) in Filipendula ulmaria herb, flowers and leafs by thin-layer chromatography, differential spectrophotometry with aluminum chloride reagent (total flavonoids in terms of rutoside), gravimetry (total extractives, extracted by water), permanganatometric titration (total tannins in terms of tannin). Rutoside, tannin, gallic acid and salicylic acid were identified in Filipendula ulmaria herb, flowers and leafs by TLC. Also we analyzed content of substances extracted by water, flavonoids and tannins. Total extractives, extracted by water in F. ulmaria herb is 13.12±0.10%, in leafs – 13.98±0.37%, in flowers – 18.09±0.17%. Total tannins in F. ulmaria herb is 11.87±0.47%, in leafs – 12.06±0.18%, in flowers – 12.26±0.29%. Total flavonoids in F. ulmaria herb 4.34±0.17%, in leafs – 6.98±0.23%, in flowers – 11.75±0.57%. The obtained data will be used for development of a pharmacopoeial monograph project "Filipendula ulmaria (L.) Maxim., herba" for inclusion in the State Pharmacopoeia of the Russian Federation.

Coronavirus disease (CoViD-19) is an infection of the respiratory system caused due to various viruses affects the respiratory pathway, and it can spread from one person to another by coughing, sneezing or physical contact. Commonly include cough, cold, fever are the symptoms. Viral diseases increase worldwide concern, including emerging and chronic viruses. The invention of new anti-viral drugs from plants has implicit in the past. The Coronavirus disease 19 (COVID-19) caused due to severe acute respiratory syndrome, which is a transmittable and pathogenic viral infection. Several traditional medicines of plant origin having antimicrobial and anti-inflammatory properties some have been studied for their anti-viral properties and immune-modulating effects. Herbal drugs are now in massive requirement in the developing countries for primary health care not because of their economical but also for better civilising adequacy, improved compatibility with the human body and significantly fewer side effects. This review gives an overview of some critical traditionally used medicinal herbs with anti-viral properties—the literature regarding the drugs of this group, collected from Ayurveda classics. Research articles are collected from published material and discussed per therapeutic actions. Most of the Herbs are with Katu Rasa (pungent) and Ushna Virya (hot potency). They are indicated in diseases, viz. Kasa (cough), Shwas (asthma), Krumi (worm/ infection). Krumihara property drugs which are correlated with anti-viral action helps to prevent against Novel coronavirus infection.
