Aims and objectives: Stephania japonica (Thunb.) Miers belonging to family Menispermaceae and is a highly demanded medicinal plant used in the name of Rajpatha for treatment of fever, malaria, jaundice, and various stomach disorders by the local traditional healers and pharmaceuticals for the preparation of medicines for related diseases. It is widely distributed in Northeastern India, i.e., Arunachal Pradesh, Assam, Manipur, Meghalaya, Mizoram, Nagaland and Tripura. Because of acute pressure on wild sources due to rapid exploitation and changing forest areas into agriculture land and various other developmental activities in a very short time, there will be the shortage of drug in the wild and needs to be cultivated this plants along with several others. Accordingly, a study has been carried out with the aim to develop easily accessible agro-technique for undertaking cultivation by the farmers in an easily accessible manner. Outcome of the study: This plant is a highly demanded medicinal plant distributed in North East India. Its cultivation is through tuberous root. Seeds also act as a tool for giving rise to new plants initiating from the mature viable seeds fallen on the ground. Seed germination is more accessible for this plant. The authors has developed various cultivation parameters in Regional Ayurveda Research Institute, Itanagar (Arunachal Pradesh) through seed germination and roots. Conclusion: Seeking out the practices of traditional use of tuberous root of S. japonica (Thunb.) Miers, there is an urgent need of cultivation. Accordingly, easily acceptable techniques for its cultivation is described in the present communication and cultivation can be made by establishing plant nurseries.

Aim and objective: The present communication deals with report of medico-ethnobotanical claims and folklore medicinal plants documented during survey made to areas in and around Sunaikuchi and Khulahat Reserve Forests in Morigaon district of Assam. Materials and methods: Field surveys were conducted in the study area where folk healers were interviewed for documentation of medico-ethnobotanical information. The reported folklore plant specimens were collected, identified, and preserved. Results: The reported folk claims involve 10 medico-ethnobotanical claims for 9 disease conditions involving 12 medicinal plants under 12 genera represented by 11 families. Indications of respective species in traditional system of medicine have been reviewed against documented folklore medicinal plants for further validation of folk claims. Conclusion: Folklore plants are suggested for further validation and experimental screening. Significance: Corroboration with indications of traditional system of medicine will validate the use of the folklore plant.

Aim: To explore and document the prominent medicinal plants of North District of Tripura through medico-ethnobotanical survey (MEBS) tours. Materials and methods: Ethno-medico-botanical survey team collected plant specimens, digitally photographed and enlisted characters, and allotted a field number for each specimen in the field with global positioning system (GPS) reading. Collected plant specimens were pressed, processed, poisoned, rearranged, mounted, identified, documented, accessioned, and incorporated in the herbarium and followed by enlisting of medicinal plants mentioned in Ayurveda. Result and discussion: A total of 223 plant specimens of 178 genera of 73 families have been collected and digitally photographed from the forests of North district, Tripura and enlisted 98 medicinal plants mentioned in Ayurveda of listed and presented in the tabular form. The district populace consists of Tribes and non-tribes and follows traditional practices and traditional medicines prepared from plants available in their surrounding and from nearby forest. Summary and conclusion: The thickest and green forest in North District of Tripura is with rich biodiversity of medicinal plants mentioned in Ayurveda and herbal medicinal plants. As this area is rich in medicinal plants mentioned in Ayurveda can be used for the establishment of herbal pharmaceutical industry. It may play a very important role in job creation and social upliftment and also in the management of good health of tribes and non-tribes of Tripura and other states of India.

Aim and objective: The present review enlists some medicinal plants possessing nephroprotective and nephrocurative activity against drug-induced nephrotoxicity. Background: Nephrotoxicity, one of the most common kidney problems, occurs when the body is exposed to a drug or toxin. A number of therapeutic drugs such as antibiotics, chemotherapeutic agents, and NSAIDs can weaken the kidney function resulting in acute renal failure, chronic interstitial nephritis, and nephritic syndrome. Many herbs possess nephroprotective properties due to presence of several potent phytoconstituents and other chemical compounds. Many herbs and their formulations have been used in traditional system of medicine to cure kidney disorders since millennia without any side effects. This review presents classical examples of some medicinal plants and nephroprotective compounds present in them. Review results: Based on the plethora of evidences presented for the plant-derived nephroprotective agents, the plants reviewed belonged to 12 different families (dicotyledons). The seeds and leaves have been largely reported to treat renal disorders Phenols and flavonoids were observed as the common bioactive compounds along with terpenes (mon-, di- and sesq-) of different classes. Conclusion: The phytochemical review of different plants reveals the presence of many bioactive compounds such as sesquiterpenoids, flavonoids, phenols, steroids, and alkaloids with different biological activities. These compounds possess potent nephroprotective properties. Clinical significance: The extracts of the plants reviewed exhibited significant dose-dependent nephroprotective and nephrocurative activity (5–600 mg/body weight).

Aim and objective: Mallotus philippensis (Lam.) Muell. Arg., family Euphorbiaceae, one of the medicinal plants highlighted for its uses in almost all classical texts of Ayurveda, is also traditionally used by local traditional healers for various disease conditions. The present review aims to collect all available ethnomedicinal information and research updates on M. philippensis. Material and methods: Reported ethnomedicinal uses of M. philippensis from available 20 books related to medicinal plants and 77 research articles on ethnomedicine, published till February 2020, were reviewed. Name and place of the reporting tribe, vernacular names, parts used along with their therapeutic indications, with specific method of administration, if any, through either external (E) or internal (I), as well as economic use were also noted. Results and discussion: Mallotus philippensis has been reported for its therapeutic uses in 18 states of India and other 3 countries. Its fruit, seed, plant part unspecified, leaf, stem bark root, flower, branches, whole plant, and young shoot are used in 67 different disease conditions, either through internal administration or external applications. Among these, maximum are indicated in the treatment of worms, skin disease, wounds, burn, etc. Its fruits have maximum applications in 48 disease conditions, followed by seed in 27, plant part unspecified in 27, leaf in 20, stem bark in 17, root in 11, flower in 9, branches in 1, whole plant in 1 and young shoot in 1 disease conditions. Its different parts are also used in economically as a dye, pesticide, religious rites, etc. Pharmacological studies report its anthelmintic, antibacterial, anticancer, purgative, and wound healing activities. Conclusion: Mallotus philippensis is having multifaceted ethnomedicinal uses. Much of the information are not noted in the classical texts of Ayurveda. Its use in worms, skin disease, constipation, rheumatism and wounds should be evaluated through pharmacological and clinical studies to establish the ethnic claims.
