    • Aflatoxins
    • Mycotoxin produced by Aspergillus sp.
    • 6 th among the 10 most important
    • healthrisks WHO
    • 25-40% of cereals worldwide are
    • contaminated with mycotoxins FAO
    • Aflatoxin B 1
    • Most toxic among mycotoxins & found
    • widely in greater concentration in food
    • throughout the world
    • Potent hepatocarcinogenic, mutagenic,
    • teratogenic and immunosuppressive

  • Everything can wait, but not agriculture
  • Biodegradable environmental safety Botanical Pesticide as Fourth Generation Pesticides Systemic in nature Indigenous renewable WHAT NEXT ????.... Diverse biological effects less chance of resistance development Pesticidal plants and its components for million of years in nature without any adverse effect High level of safety for humans, animals, fish and other non target organisms

    • Why Herbal Medicine 
    •  
    • It is being used by about 80% of world population primarily in developing Countries for primary health care
    • They have stood the test of time for their safety
    • Efficacy
    • Cultural Acceptability
    • Lesser side effects
    • The chemical constituent present in them are a part of the physiological function of living flora and hence better compatibility
    • For age related disease – memory loss , diabetic wounds , liver disorder for which no modern medicine
    • Renewable and Ecofriendly Raw material
    • Will bring economic prosperity of the masses knowing these raw materials
    • Herbal products are and will remain much more affordable than synthetic drugs

  • PHARMACOGNOSY Herbal raw material evaluation and standardization Authentication of crude drugs by analytical techniques Toxicological screening Multidimensional approach of pharmacognosy towards quality control of herbal medicines Development of phytochemical markers for identification
    • India should occupy a significant position in the world trade of herbal drugs
    • The time has come to compile and document traditional knowledge on herbal medicine
    • Efforts should be made to cultivate medicinal plants as field crops .
    • Conservation should be in appropriate ecological situations.
    • Standardization as per WHO guide lines
    • We can certainly be world leader in this field

    • The Indian Flora is more varied than that of any other country of equal area in the eastern hemisphere, if not on the globe” J. D. Hooker (1904).
    • A significant feature of Indian flora is the confluence of floras from the surrounding countries like Malaya Tibet, china, Japan , Europe and even from widely separate continents like America, Canada and Australia Rao (2006), Subramani et. Al. ( 2005).
    • 40 per cent of flowering plants in India are foreign and naturalized in various parts of the country. Maheshwari (1962)

    • b. Bioprospecting of biodiversity ---documentation, identification of plants of
    • potential economic value
    • Higher plants are untapped reservoir of various valuable chemicals awaiting their intensive exploitation for their biological properties for health of plants and animals.
    • The perusal of literature shows that a large number of bioactive agents have been overlooked or rejected by the pharmaceutical and agrochemical firms which have commercialized only a few strongly active ones for a quick cure , rapid action , heavy financial return in spite of their considerable damage out side the intended targets.
    • The situation may now be reversed and that natural products in natural combinations and methods such as used in the past in Ayurveda , Unani and other such systems may again be adopted than artificial ones in medicine and particularly in agriculture.
