Medicinal plants play a major role in the field of Ayurveda. Identification of the correct medicinal plants that goes in to the preparation of a medicine is very important in ayurvedic medicinal industry. It is due to non-availability, wrong identification, lack of knowledge, ambiguity, seasonal availability and high cost of the drugs, the original drugs are replaced by its substitutes and used by the physicians for several Ayurvedic preparations. As a result of which the medicine loses its efficacy and its medicinal properties. Hence, proper identification and correct usage of drugs are very important for the preparation of Ayurvedic medicines. In this research paper, a list of 5 medicinal plants are highlighted along with its different sources, with local names and Ayurvedic names, photographs, which is essential for identification of drugs along with its differentiating characters.
India is known for a rich tradition of ethnobotanical medicine-based remedial practices primarily involving medicinal plants and their products. Close to 25,000 effective plant-based drug formulations have been reported in traditional Indian folk medicine. History of drug non-availability or limited availability of quality raw materials is as old as Ayurveda. Since, the availability of quality raw plant material is a burning issue, treatment has to be done appropriately with the available drugs only. According to an estimate over half a million tonnes of the raw materials are indiscriminately collected from wild, mostly following destructive harvesting procedure and thus about 165,700 hectares forest being clear-felled each year.
Hence alarming situations have resulted into short supply, high prices, forced import, or substitution and adulteration in crude drugs1.
Ayurvedic medicinal plant drugs play a vital role in healing several diseases, where different phytochemical constituents are responsible for curing many diseases. Several drugs in the crude drug market are being sold by the same plant name with different botanical sources/ names leading to confusion, while purchasing the drugs. With increasing international trade in herbal medicinal products, there is also increasing concern about the widespread adulteration and species admixtures in the raw herbal trade. It has been observed, that many foreign substances are added in place of original drug partially or fully, which is inferior or substandard in therapeutic and chemical properties. Addition of low grade or spoiled drugs or entirely different drugs are similar to that of original drug with an intention of enhancement of profits,2 due to which, faith in herbal drugs has declined. For promotion of herbal products it has become one of the greatest drawbacks.3In adulterated drugs, it is found that the adverse event reports are due to the presence of an unintended herb.4 Hence, proper identification is very important and one should thoroughly know to identify the drugs and its importance for the preparation of different medicines. In this paper, 5 important drugs used in Ayurvedic medicine like Maricha, Kesar, Bhringaraja, Ashoka, Guduchi, are elucidated with its botanical names, sanskrit names, kannada names, its different botanical sources along with its identification characters along with its photographs, uses in Ayurvedic preparations to facilitate the identification of drugs. Hence, an attempt has been made to highlight the identification characters along with photographs which will be useful for the identification and differentiating the genuine and its other alternative sources.
MATERIAL AND METHODS:
In this research paper 5 different medicial drugs have been studied along with their respective sources which have similarities in one or another way. Available Ayurvedic and allied literature were referred for identification of plants. Relevant information from various texts, published research articles and internet has been used. Some of the photographs were collected directly from Survey of Medicinal Plants Unit of the centre and some from standard authentic online world encyclopaedia.

Medicinal plants have been used in health care since time immemorial the demand for herbal plants has rapidly increased in the last decades. Medicinal plants contribute 80% of raw materials for traditional drug preparation. The worldwide trade for medicinal plants and its products is estimated to be $60 billion annually. However, there has been an increase of unethical commercial trades, whereby the authentic medicinal herb is substituted by less effective and sometimes deleterious herbs and unlabelled fillers.37 Therefore, it is important to understand and study various patterns of adulterations and substitution. Identification of a species is the most critical task which necessitates application of instinct, knowledge and skill. A correctly identified species is given recognition with the help of an appropriate name. The events of misidentification of plant species, inadvertent use of totally unrelated species or by closely related inferior quality species can hinder their medicinal use, the adverse effects of which may even kill a consumer. The medicinally useful plants and plant products must have their specific identity correctly ascertained with standardized circumscription and nomenclature for quality control and prevention of adulteration of drugs38. Adulteration may be of various reasons such as improper use of ingradients for manufacturing drugs, substitution of fake cheap ingredients, use of defective/inferior ingradients, lack of knowledge amongst the developers for manufacturing the drugs, ignorance and human error. Adulteration may also be happening due to commercial interest of drugs manufacturers and vendors.
For development of pure Ayurvedic drugs meeting the official standards having potency the following steps should be followed without any compromise. The right identification of plant, selection of raw material from the identified plant etc. right process of drug development and non-substitution of inferior substitutes should be followed. In the present study 10 different medicinal drugs are considered and possible substitute of each and every drug are compiled.
Due to similarity in morphology, color, size and shape, careless collection, easy availability, cost effectiveness, lack of knowledge, confusion in name, different sources of Piper nigrum L. has been used as adulterated with Carica papaya L., Mirabilis jalapa L., Piper cubeba L.f., Aframomum melegueta K.Schum., Lantana camara L.,Persicaria amphibia (L.) Delarbre, Scinus molle L., Vitex agnus-castus L., Vitex altissima L.f., Asparagus racemosus Willd.Like wise due to unavailability of kesar in regional areas, found in himalyan region only and similarity in morphology it has been adulterated with Carthamus tinctorius L., Nelumbo nucifera Gaertn., Jasminum sambac (L.) Ait Tagetes patula L.In the similar way other drugs are also adulterated due to above mentioned reasons. World Health Organization (WHO), in its publication on quality standards for medicinal plant materials, recommends rejecting any batch of raw material, which has more than 5% of any other plant part of the same plant (e.g. stem in leaf drugs), never the less if they are derived from the authentic plant. Hence, this work intends to enhance the research in identification of medicinal plants.
With the growing human footprint on the planet, mother earth is stretched out for survival. The natural resources are stretched and man is improvising to meet its ends. In the process the authentic and organic resources are being diluted. Ayurveda is one of the fields which is affected because all ayurvedic medicines have a plant source and its potency is being challenged due to this adulteration. To win the faith of people in Ayurveda system it is important to ensure the potent efficacay and safety of medicinal drugs. Education among the vendors, collectors and masses regarding the ill effects and side ffects of adulterated drug.
