Medicinal plants have been of existence from time immemorial. Over 250,000 exist and are believed to have different medicinal activities. Moreover, only the activities of about 50,000 plants have been examined. The use of plants for the remedy of diseases is usually termed phytotherapy, complementary and alternative medicine or phytomedicine. These plants have been classified based on part used, habit, habitat, therapeutic value, Ayurvedic formulations in which they are used and Botanical classification. Plant phytochemicals confer medicinal plants their medicinal activities and has been broadly classified into primary constituents which include the common sugars, amino acids, chlorophylls, proteins, purines and pyrimidines of nucleic acids etc. while secondary constituents are the remaining plant chemicals such as alkaloids, terpenes, flavonoids, lignans, plant steroids, curcumines, saponins, phenolics, flavonoids and glucosides. The activity of the phytochemicals depends on their structures. Several methods of extraction of this useful phytochemicals exists depending on the target phytochemical. Medicinal plants have shown promising antimicrobial activities, anti-helminthic, anticancer, antidiarrheal and antiviral activities. Phytotherapy have several advantages over synthetic drugs. Moreover, it also has limitations. The characteristics, advantages, limitations of phytotherapy is been reviewed in this work.

Medicinal plants have been discovered in Indian medical practices to control many human diseases since prehistoric times. Plants synthesise numerous chemical compounds which acts as defence mechanism against insects, fungi, diseases and herbivorous mammals. Medicinal plants have been known to be an important potential source of therapeutics or curative aids. The use of medicinal plants has attained a commanding role in health system all over the world. This involves the use of medicinal plants not only for the treatment of diseases but also as potential material for maintaining good health and conditions. Many countries in the world, that is, two-third of the world’s population, rely on herbal based medicine for primary health care because of cultural acceptability, compatibility and adaptability with the human body and possess zero-side effects. Since past, remedy drugs were prepared from plant extracts to combat the chronic disease worldwide.
Medicinal plants: Role, distribution and future
Journal of Pharmacognosy and Phytochemistry, 2020
Medicinal plants have been used for healthcare since time immemorial. Application of plants to prepare medicine has been realized through hit and trail method, and gradually man became able to fulfill his needs from his surroundings. The use of medicinal plants was started by Japanese for carrying out rituals, food flavoring and treating various diseases. Studies have been carried out globally to verify their potential and some of the findings have given rise to what we call plant-based medicines. Being an important source of medicine, these plants have always been of utmost importance in virtually all cultures of civilizations. Medicinal plants are regarded as rich resources of traditional medicines and not only this but these plants serve as an important source for many modern medicines as well. It is the presence of secondary metabolites which is responsible for their characteristic features. By standardizing the health of active plant-derived compounds, herbal drugs can provide ...
Effects of Some Medicinal Plant Extracts
International Journal of Contemporary Research in Engg. and Tech., 2019
Antibiotics provide the main basis for the therapy of microbial (bacterial and fungal) infections. Since the discovery of these antibiotics and their uses as chemotherapeutic agents there was a belief in the medical fraternity that this would lead to eventual eradication of infectious diseases. However, overuse of antibiotics has become the major factor for the emergence and dissemination of multi-drug resistant strains of several groups of microorganisms. The worldwide emergence of Escherichia coli, Klebsiella pneumoniae, Haemophilus and many other â-lactamase producers has become a major therapeutic problem. Multi-drug resistant strains of E.coli and K. pneumoniae are widely distributed in hospitals and are increasingly being isolated from community acquired infections. Alarmingly, the incidence of nosocomial candidemia has risen sharply in the last decade. All this has resulted in severe consequences including increased cost of medicines and mortality of patients. With the widespread use of antibiotics and other antimicrobial agents, more and more of the clinical multidrug-resistant (MDR) pathogen appeared, and the degree of resistance has become increasingly serious. At the same time, because of the difficulty in developing chemical synthetic drugs and because of their side-effects, scientists are making more efforts to search for new drugs from plant resources to combat MDR microbial infections. Presently there has been an increase in the use of plant microbicides because of the necessity of finding safer agents and the need for preventing environmental degradation.
PERSPECTIVES IN MEDICINAL PLANTS
India is a vast repository of medicinal plants which constitutes the main resource-base for the primary health care system in the country. According to World Health Organization (WHO) more than one billion people rely on herbal medicines. It is well known that all the major systems of medicines Ayurveda, Homoeopathy, Siddha, and Unani are largely based on the drugs ofplant origin. Consequently, the demand for herbal drugs is accelerating day by day due to the reasons that these are inexpensive, almost non-toxic and without any side effects. In view of the fact, there has been growing appreciation for the study, evaluation, utilization and then the conservation aspect of medicinal plants. The extensive explorations and scientific efforts of the people have enabled the discovery and development of new drugs from the plant sources for the treatment of ailing people and also for the domestic and industrial needs. Some of these plants are Taxus, Vinca, Artemisia, Thaumatococcus, Stevia, Sorbus, etc. In the present paper, an emphasis has been made on some aspects of medicinal and their allied plants covering historical background, their proper and correct identification, some plant-derived compounds, scientific approach for quality and quantity enhancement of active principles, ways and means of conservation, etc.

Humans have relied on herbal medicines in health care and the treatment of numerous diseases since the very early stages of civilization. Herbal medicines or phytomedicines not only treat sickness but also guard against its complications simultaneously. The continuous use of synthetic medications is not safe for health because of their extreme negative impacts. So now a days, we can estimate that in some developing countries, such as the USA and England, herbal drugs make up to 25% of all consumption; on the other hand, in a few nations that are rapidly developing, like India and China, it comprises up to 80%. All over the world, more than ten thousand medicinal species are present. India is a well known producer of herbal plants that have a history of being used medicinally. As per the data of the International Union for Conservation of Nature (IUCN) and the World Wide Fund for Nature (WWF), there are 50000-80000 types of flowering plants that have medicinal value globally.

Medicinal Plants and Health in Human History: From Empirical Use to Modern Phytotherapy
Journal of the Siena Academy of Sciences
Phytotherapy is the science that deals with the treatment and prevention of diseases through medicinal plants and herbal products. The use of herbs as medicine is the oldest form of healthcare known to humanity and has been used in all cultures throughout history. It is known that even today over 80% of the world population depends on herbal medicines. The quality of herbal medicines is believed to be directly related to its active principles, but herbal medicines can be variable in their composition. Therefore, it is necessary to use an extract that is well defined in its chemical composition and in the quantity of specific active principles; and actually, to obtain constant efficacy and safety, standardized medicinal plant extracts are being used. Clinically confirmed efficacy and best tolerability and safety of standardized or quantified medicinal plant extracts are the key for a successful phytotherapic approach.
