Anethum sowa Roxb. ex fleming: A review on traditional uses, phytochemistry, pharmacological and toxicological activities

Plant derived active compounds of ayurvedic neurological formulation, Saraswatharishta as a potential dual leucine zipper kinase inhibitor: an in-silico study

Recent findings have highlighted the essential role of dual leucine zipper kinase (DLK) in neuronal degeneration. Saraswatharishta (SWRT), an ayurvedic formulation utilized in traditional Indian medicine, has demonstrated effectiveness in addressing neurodegenerative diseases. Herein, we aim to delve into the atomistic details of the mode of action of phytochemicals present in SWRT against DLK. Our screening process encompassed over 500 distinct phytochemicals derived from the main ingredients of the SWRT formulation. Through a comparative analysis of docking scores and relative poses, we successfully identified four novel compounds, which underwent further investigation via 2 × 500 ns long molecular dynamics (MD) simulations. Among the top four compounds, CID16066851 sourced from the Acorus calamus displayed the most stable complex with DLK. The molecular mechanics Poisson - Boltzmann surface area (MM-PBSA) calculations highlighted the significance of electrostatic and van der Waals interactions in the binding recognition process. Additionally, we identified key residues, namely Phe192, Leu243, Val139, and Leu141, as hotspots that predominantly govern the DLK-inhibitor interaction. Notably, the leading compounds are sourced from the Acorus calamus, Syzygium aromaticum, Zingiber officinale, and Anethum sowa plants present in the SWRT formulation. Overall, the findings of our study hold promise for future drug development endeavors combating neurodegenerative conditions.Communicated by Ramaswamy H. Sarma.

Management of allergic rhinitis with Rajanyadi Churna and Guduchi Kwatha- A case report

Allergic Rhinitis is an immunological inflammatory response of the nasal mucosa to airborne allergens. Although Allergic Rhinitis is not a life-threatening disease, the symptoms of Allergic Rhinitis can be particularly bothersome and disruptive to a patient's sleep and overall quality of life. The coexistence of other allergic conditions like Asthma is very common. No satisfactory treatment is available in modern medicine for this disease. There is a need to search for satisfactory treatment available in another medical system. We present a case of Allergic Rhinitis that was successfully treated with Ayurvedic medicines. Allergic Rhinitis is characterized by watery nasal discharge, nasal obstruction, nasal mucosal pallor, sneezing, and itching in the eyes, palate, and pharynx. A 18-year-old female patient presented with complaints of sneezing (80-100/day), rhinorrhea (watery discharge from nose), heaviness in the head region, weakness, and loss of concentration hampering daily life activity for one year. The patient's clinical findings and symptoms were suggestive of Allergic Rhinitis, which is of perennial type. According to Ayurveda diagnosis was done as Vata-Kaphaj Pratishyay. Rajanyadi Churna was given to the patient for 15 days along with Guduchi Kwath (∼Guduchi decoction) followed by Shaman Snehapan (∼internal oleation) with Mahatiktak Ghrita. The patient experienced a reduction in all the symptoms after 15 days. Allergy markers i.e. Absolute Eosinophil Count reduced to 360 cells/cu mm from 704 cells/cu mm and eosinophils in CBC reduced to 4.1%. The primary complaint of sneezing was significantly reduced to 3-4 times/day after completing the treatment. Ayurvedic therapeutic interventions other than Nasya (∼Nasal oleation), and Dhoompana (∼medicated smoke) modalities showed encouraging results in managing Allergic Rhinitis in a short duration of time. This approach may be taken into consideration for further treatment and research work for Allergic Rhinitis.

Application of essential oils as natural biopesticides; recent advances

There is an urgent need for the development of sustainable and eco-friendly pesticide formulations since common synthetic pesticides result in many adverse effects on human health and the environment. Essential oils (EOs) are a mixture of volatile oils produced as a secondary metabolite in medicinal plants, and show activities against pests, insects, and pathogenic fungi. Their chemical composition is affected by several factors such as plant species or cultivar, geographical origin, environmental conditions, agricultural practices, and extraction method. The growing number of studies related to the herbicidal, insecticidal, acaricidal, nematicidal, and antimicrobial effects of EOs demonstrate their effectiveness and suitability as sustainable and environment-friendly biopesticides. EOs can biodegrade into nontoxic compounds; at the same time, their harmful and detrimental effects on non-target organisms are low. However, few biopesticide formulations based on EOs have been turned into commercial practice upto day. Several challenges including the reduced stability and efficiency of EOs under environmental conditions need to be addressed before EOs are widely applied as commercial biopesticides. This work is an overview of the current research on the application of EOs as biopesticides. Findings of recent studies focusing on the challenges related to the use of EOs as biopesticides are also discussed.
