Is there evidence that Withania somnifera is effective in tumor suppression - Dissertation pillow slipAt present, plant products have already been used as a standard chemotherapeutic agent. For example, vinblastine (from periwinkle (Catharanthus)) and paclitaxel (from Yew tree (genus Taxus)) are already a part of chemotherapeutic options used against preservecer (Choudhary et al., 2010). Because a high number of individuals still suffer from genus Cancer, the search is still ongoing for the compound, both natural and synthetic, that can hopefully decrease the cancer-caused mortality rate considerably. Withania somnifera, commonly called as Ashwagandha, is a member of Solanaceae family, in concert with Nicotiana (tobacco), Solanum (potato), and Capsicum (pepper). In herbal medicine, W. somnifera has already been used against various health conditions. In Pakistan, it has been used against respiratory problems (Choudhary et al., 2010). In India, it has been recognized as an aphrodis iac and invigorating medicine (Choudhary et al., 2010). The plant is also used against intestinal ulcers, rectal bleeding and irritable bowel (Pawar et al., 2011). Several withanolides isolated from Ashwagandha were also engraft to possess anti-glycation, possibly against diabetes, and anti-pyretic effects (Choudhary et al., 2010). ... EVIDENCE OF TUMOR SUPPRESSION ACTIVITY OF Withania somniferous In this lit review, four journal articles, ranging from 2003 to 2011, were looked into. Most of the methods used by these studies are in vitro, and only one victimisation in vivo, although in an experimental model (rats). Google scholar was used as a search engine, with the results hold to 2000 to 2011. The search terms used were Withania somnifera cancer. Later in this paper, the quality of the research would be assessed in the main based on the methods used in the purification and activity assays. Activity of crude methanolic extract against NCI-H460 Compounds from the leaves and st ems of W. somnifera were tried for its anti-proliferative activity against human lung cancer cell line NCI-H460 in vitro. In this study by Choudhary et al. (2010), tested for growth inhibitory and cytotoxic activities were the (1) crude methanolic extract of W. somnifera, (2-4) three isolates, and the positive control (5) doxorubicin. The isolates were obtained using silica gel chromatography. They were then characterized using mass spectrometry and NMR. One of the three compounds were identified as withaferin A, period the other two were found to be its chlorinated steroidal lactone and epoxide derivatives, respectively. In testing their activity, GI50, or the concentration create 50% growth inhibition of NCI-H460 cells, and LC50, or the concentration causing the death of 50% of the same cancer cell line, were measured for all the five test substances. The obtained data were compared using one-way ANOVA and Duncans multiple range test (p 0.05) using SPSS 17 program. Finally, th e report also mentioned the presence of other studies that realize the growth inhibitory activity of withaferin A against other
