Medicinal Plants: the Medical, Food, and Nutritional Biochemistry and Uses
International Journal of Advanced Academic Research, 2019
This article focuses on the medical, food, and nutritional biochemistry and uses of medicinal plants. Medicinal plants are used with the intention of health maintenance, to be administered for specific conditions, or both, whether in modern or in traditional medicines. Many phytochemicals with established or potential biological activity have been identified in plants. The compounds found in plants (phytochemicals) are of several kinds, but most are in four main biochemical classes: terpenes, alkaloids, glycosides, and polyphenols. Medicinal plants are used widely in non-industrialized societies and developing countries in Africa, Asia, and Southern America, mainly because they are thought to be very effective, cheaper than modern medicines, and readily available. Plants, including many currently used as culinary spices and herbs, have been used as medicines, not certainly effectively, from ancient times. Polyphenols of many classes are widely spread in plants. Plants having phytoestrogens, a type of polyphenols, have been administered for decades for gynecological conditions, such as fertility, menopausal, and menstrual problems; among these plants are Pueraria mirifica, anise, kudzu, angelica, and fennel. The astringent rind of the pomegranate, having polyphenols known as punicalagins, is commonly used as a medicine. Angelica, having phytoestrogens, has been used for gynaecological disorders for long. Nicotine, an alkaloid, from tobacco directly binds to Nicotinic acetylcholine receptors in the body, accounting for its pharmacological effects. Cardiac glycosides are powerful drugs from the medicinal plants including lily of the valley and foxglove; they include digitoxin and digoxin which support heart beating, and work as diuretics. Terpenoids and terpenes of many kinds are contained in many medicinal plants, and also in resinous plants such as conifers; they are strongly aromatic. A number of the terpenoids and terpenes have medicinal uses: for instance, thymol (an antiseptic) was once used as an anti-worm medicine (vermifuge). In most of the developing countries, especially in the rural areas, local traditional medicine, inclusive of herbalism, is the lone source of health care for individuals, while in the developed countries, alternative medicine including dietary supplements is aggressively marketed using claims of traditional medicine.

Medicinal plants are a gift of nature and the history of medicinal plants is very ancient. The value of medicinal drugs and their alkaloids are very effective against many human diseases. The drugs are synthetically prepared into the industries but the raw material of drugs can be obtained from various plant parts like stem, bark, roots, leaves, and other fibrous parts, etc. The pharma industries of drugs are very effective herbal drugs but they are very costly. The life of these drugs is not long when compared to herbal medicines. The human body is very sensitive to drugs and when any wrong drugs are applied to the body, then our immune system suppresses the drugs and produces a response against the drugs. The effectiveness of drugs and their specificities only on its targeting site take action upon it. The various microbial diseases can affect the human body by various modes of infection. The various techniques and methods are isolated medicinal drugs from medicinal plants.

The present review summarizes the wide use of various plant extracts and herbal fed additives in a specific dose during the scheduled vaccination regimen may be helpful in obtaining higher protective antibody against different infections including production and development of more effective cell mediate immune response for protection against various bacterial, viral and other diseases. Herbal formulation may be therefore recommended for use as positive immunomodulator in normal and immunocompromized susceptible animals and birds. However, more sufficient researches are in demand to be carried out to establish the medicinal facts of the mentioned indigenous plants and fruits. In infants, use of neem oil is fatal. Some disadvantages of neem includes miscarriages, abortions and infertility. Although, American Cancer Society recommends the centella herb for having anticancerous properties, but research in this regard are in progress. Preliminary experimental animal researches have proved that the papaya seeds have potential contraceptive and abortifacient effect, but is non-teratogenic for the presence of phytochemicals in it. Many herbal plant preparations are prescribed to strengthen host resistance. Many useful plants fall under this category. They exhibit immunomodulatory activities. One such plant, Tinospora cordifolia, commonly called 'Guduchi' has been examined for its immunomodulatory properties. Guduchi means to rejuvenate dead cells. It is widely used in veterinary folk medicine and has also been claimed to be beneficial according to 'Ayurveda' for the cure of jaundice, skin diseases, diabetes, anemia, emaciations and various infections for its anti-spasmodic, anti-inflammatory, antiarthritic and anti-allergic properties. It has also been reported that it improves the phagocytic and bactericidal activities in patients suffering from polymorphism in surgical jaundice.

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.
MEDICINAL PLANT RESOURCES: MANIFESTATION AND PROSPECTS OF LIFESUSTAINING HEALTHCARE SYSTEM
Medicinal plants are the principal health care resources for the majority of people all over the world. The healing properties of herbal medicines have been recognized in many ancient cultures. The traditional medical systems such as Ayurveda, Siddha and Unani are part of a time-tested culture and honored by people still today. Pharmaceutical importance of plants has led to the discovery and adoption of plant extracts which were commonly used in traditional medicine, as alternative source of remedy. A vast diversity of herbal ingredients, major proportion of which is derived from wild, provide the resource base to the herbal industry. Despite the increasing use of medicinal plants, their future, seemingly, is being threatened by complacency concerning their conservation. Global demand for herbal medicines is accompanied by dwindling supply of medicinal plants due to over-harvesting, habitat loss and agricultural encroachment. As millions of rural households use plants for self-medication community involvement in monitoring use and status of medicinal plants can contribute to effective strategies for their sustainable use. INTRODUCTION Human life and knowledge of preserving it as a going concern must have come into being almost simultaneously. All known cultures of the past-Egyptian, Babylonian, Jewish, Chinese, Indus-valley etc. had their own glorious and useful systems of medicine and health care. Herbal medicines also called botanical medicines or phytomedicines, refer to the use of any plant seed, berries, roots, leaves, bark or flower for medicinal purpose. Early herbalists believed that the plant part resembling any part of human body was considered useful for the ailments of those parts, and there is no part of body without its corresponding herb, a hypothesis known as the, " Doctrine of Signature " (Baquar, 2001). The economic significance of medicinal plants stems from the fact that the number of patients suffering from chronic ailments is on the rise and drugs from medicinal plants are proving to be more effective in treating such disorders (Deshpande et al., 2006).
