  • MEDICINAL PLANTS • Plants that have healing properties are termed as medicinal plants or herbs. • Many plants produce special substances in their roots, leaves, flowers, or seeds that help them to survive. • Since earliest times, people have gathered these substances to create herbal medicines to treat certain diseases. • Today’s plant-based drugs treat a range of diseases, from headaches to cancer.
  • HISTORY • Herbal medicine is the oldest form of healthcare. • Herbs had been used by all cultures throughout history. • Primitive man observed and appreciated the great diversity of plants available to him. • Early humans learned about the usefulness of plants by observing animals. • As time went on, each tribe added the medicinal power of herbs in their area to its knowledgebase.
  • Cont’d • They collected information on herbs and developed well- defined herbal pharmacopoeias. • Indeed, well into the 20th century much of the pharmacopoeia of scientific medicine was derived from the herbal lore of native people. • Many drugs commonly used today are of herbal origin. • Indeed, about 25 percent of the prescription drugs are of plant origin.
  • MODERN MEDICINE • The tendency in modern medicine is to use synthetic drugs, that eventually were modelled on compounds obtained mainly from plants. • The World Health Organization (WHO) estimates 80 %of the world population, presently use herbal medicine for some aspect of primary health care. • In 1997 plant-derived anti-cancer drugs such as taxol, saved at least 30,000 lives per year in the US • Approximately $ 5 billion were spent in USA on phytoceuticals (1998). • The most significant medicinal plants used for prescription drugs contain steroids or alkaloids.
  • THREATS • According to the World Conservation Union (IUCN), about 15,000 medicinal plant species may be threatened with extinction worldwide from overharvesting. • Scientists and policymakers are proposing new procedures and policies to safeguard our remaining medicinal treasures in the wild so that they can protect this and future generations
  • PHYTOMEDICINAL PROSPECTING • Rainforest people possess valuable knowledge about medicinal plants. • With proper research, scientists believe they might find cures for some of the world’s deadliest diseases. • INBio, Costa Rica's National Institute of Biodiversity are carrying huge projects. • To complete this ambitious task they train "community taxonomists" to identify plants and animals.
