Cancer is a major public health concern all over the world. Herbal medicines play vital role in the prevention and treatment of cancer. Some medicinal plants have been proved very effective anticancer remedies and have been used since ages. However, the drug formulations were not distinctly clear except after their proper effective assays within the system applied. Active compounds from plants such as Andrographis paniculata, Aegle marmelos, Glycyrrhiza glabra, Elephantopus scaber, Cistanche tubulosa have been reported in literature. Dried extracts prepared from these plants and their phytochemical analysis was reported. To check cytotoxic effects of the active compounds in the extracts MTT assay can be formulated. These plant extracts might possibly have effective significance on preventing cancerous tissues.
