Introduction
Medicinal plants are those plants which contain substances used for the treatment or prevention
of diseases or infections and other health disorders in human body. The medicinal value of
medicinal plants is due to substances found in the plant tissues that produce a definite
physiological action on the human body. The medicinal plants are extracted from trees and
shrubs. The common practice is the use of the bark, roots and sometimes both. The less
commonly used in this regard are the leaves while flowers or fruits including seeds are rarely
used. The herbaceous and succulent plants are uprooted and used holistically. The most
important of these substances are the alkaloid, fixed oil, essential oil, tannins, resins, etc. The
potential of such chemicals are less applied when it comes for the protection of plants from
pathogens viz. fungi, bacteria, viruses, nematodes. Certain plants possess various fungicidal and
bactericidal properties that are used to cure various fungi and bacterial diseases in humans. Their
potential is less harnessed in protection of plants from fungal and bacteriological pathogens.
