A Study on Anti-Arthritic Activity of Plants |
Natureand evolution have provided all the organisms, from lower invertebrates to thehigher organisms with a vigilant defence against any pathogenic attack orinjury faced in day to day life. In recent years, several literatures haverevealed that some orders of plants also possess certain degree of defensemechanism against the pathogen invasion or injury. Survival of any livingorganism is nearly impossible without this vigilant defense system which iswell-known as the immune system (Tracey JK, 2002). Immune system helps inmaintaining homeostasis by exploiting a dynamic network which involves the useof large number of cells and molecules capable of recognizing anddistinguishing the foreign invaders from the self-cells.
