Abstract: Introduction: Justicia betonica Linn. is an important medicinal plant belonging to family Acanthaceae. It is used for remedy for various fevers, stomach paindiarrhoea, inflammation and swelling.It has external wound healing and ulcer healing property. The plant possess many therapeutic uses such as analgesic, anti-inflammatory, anti malarial and anti microbial properties. Objectives: The present work has been designed to describe the Pharmacognostic characters of the leaves, stem, and root of Justicia betonica Linn.Materials and methods: Macroscopic, microscopic evaluation of the stem, root and leaves of Justicia betonica Linn.and powder analysis, fluorescence standards of the leaf of Justicia betonica Linn.were carried out. Results : Histological features revealed the characteristics of a typical dicot plant. The leaves had reticulate venation with prominent midrib, polygonal areoles, low palisade ratio and diacytic stomata. Two projections of collenchymatous tissue on the adaxial surface beneath the epidermis and compactly arranged palisade with plenty of chloroplasts are also typical features found in leaf. Typical chlorenchymatous cell pattern, conspicuous uniseriate or biseriate medullary rays and prominent xylem are the main characteristics of stem. Root has thickwalled xylem parenchyma and uniseriate or biseriate medullary rays. Conclusion: The findings of Macroscopic, microscopic, powder analysis, pharmacognostical standards and fluorescence analysis of leaf of this study discussed here can be considered as identifying parameters to substantiate and authenticate the plant Justicia betonica Linn.
