Not only rural people are seeking for the medical benefits from the medicinal plants but also urban people because trying to eliminate the side effects of synthetic medicine on health. Research using these three plants should not stop here and must be extensively employed by the researchers and try to get more medical properties which is useful for the public. Andrographolide from Andrographis paniculata is the active component obtained from the aerial parts of this plant, having very bitter taste. It is a bicyclic diterpenoid lactone with multiple pharmacological activities. In 1997, garlic (Allium sativum) was the most widely used natural supplement in US house-holds. Garlic was shown to be used more than twice as much as any other natural supplement. Extract of Adhatoda vasica leaves has been used for the treatment of various diseases and disorders in Ayurved and Unani medicine.

In many literature survey, researchers are trying the best to overcome the bacterial resistance by isolating compounds from the medicinal plants (one of the method) due to the resistance of bacterias towards synthetic chemicals. Overally this proved the importance of the medicinal plants. *Corresponding Author: Manoharan Sivananthan  siva8905@gmail.com International Journal of Biomolecules and Biomedicine (IJBB) ISSN: 2221-1063 (Print) 2222-503X (Online) Vol. 3, No. 2, p. 13-20, 2013 http://www.innspub.net
