Introduction

The research article focuses on the pharmacognostical study of the herb Osbeckia muralis Naudin, commonly known as 'Nela Nekkarika' in Kannada, which belongs to the family Melastomaceae. This plant, noted for its traditional medicinal use, particularly in treating respiratory ailments like cough, is endemic to the Western Ghats of Karnataka, India. Despite its ethnomedical significance among local practitioners in Dakshina Kannada District, Osbeckia muralis is not mentioned in classical Ayurvedic texts. This study aims to explore its identity through detailed macroscopic, microscopic, and powder microscopy techniques, providing a foundation for its standardization and authentication.

Macroscopic and Microscopic Characteristics

The macroscopic examination revealed that Osbeckia muralis is an erect, hirsute herb approximately 30 cm tall with ovate/elliptic leaves measuring 5 x 2.5 cm, and tetramerous purple flowers. The plant showcases notable features such as petioles of up to 4 mm in length and a distinctive structure where the stem has ridges and wings. Microscopic analysis of the stem and leaf demonstrates a range of specialized structures, including chlorenchyma cells, various types of trichomes (glandular and multicellular covering), and calcium oxalate crystals, highlighting the intricate internal organization of the plant.

Powder Microscopy Insights

Powder microscopy further explores the anatomical features of Osbeckia muralis at a granular level. The study of finely powdered plant material reveals surface views of the upper and lower epidermis, as well as the presence of multiserriate and glandular trichomes, essential for identifying the plant's characteristics when dried. Observations also include various parenchyma cells, vascular elements, and rosette crystal fibers within the leaf, which contribute to the plant's identity and potential therapeutic properties. Such findings emphasize the significance of microscopic studies in confirming the identity and quality of herbal medicines.

Conclusion

In conclusion, the pharmacognostical study of Osbeckia muralis Naudin establishes a comprehensive understanding of the plant's morphological and anatomical characteristics. The findings substantiate the plant's identity and provide critical insights for its standardization in the realm of herbal medicine. Notably, the presence of glandular trichomes and distinctive leaf structures underlines its traditional use in treating cough and respiratory ailments. This research serves as a crucial step toward recognizing and validating the ethnomedical applications of this endemic herb in Ayurveda and allied health systems.
