Christella parasitica (l.) Lev.: a potent pharmacological and pesticidal pteridophyte

Pteridophytes are the foremost vascular cryptogam on earth, and hold a unique position in plant evolution. Ferns are one of the prominent representatives of pteridophytes. This group of vascular cryptogams are distributed into 35 families with 568 genera having 13,000 species. The family Thelypteridaceae encompasses around 37 genera and has a diversity comprising 1190 species. Among these Christella parasitica (L.) Lev. (Thelypteridaceae) is one of the fern, which is an invasive vascular cryptogam with potent secondary metabolites, distinct anatomical features, pharmacological attributes along with significant pesticidal characters and anti-microbial properties. Its various applied aspects will be helpful for the researchers to focus on the thrust areas yet to be explored. Comprehensive taxonomic details of the plant have been coming out of various flora books, journals & suggestions from eminent scientists. The plant is highly active against autoimmune & gynecological disorders, food poisoning and sluggishness. However it also contributes for anti-microbial & bio-pesticidal activities. Thus, Christella parasitica holds immense potential as both a pharmacological agent and a natural pesticide. Its dual functionality highlights the importance of deeper investigation into its bioactive compounds, which may lead to innovative developments in both medicinal therapies and sustainable agricultural practices.
