Macroscopic and microscopic analyses were conducted using digital and compound microscopes. Powder microscopy, histochemical staining, preliminary phytochemical screening, and physicochemical standardization, such as ash values, extractive values, and moisture content, were performed. &lt;strong&gt;Result: &lt;/strong&gt;Macroscopic observations confirmed the fruit’s distinctive morphological features, while microscopic studies detailed the anatomical structure, including the presence of vittae, epicarp with papillae, and oil globules. Powder microscopy further verified characteristic elements such as anomocytic stomata, fibers, annular vessels, and phenolic compounds. Histochemical tests revealed the presence of bioactive compounds like alkaloids, flavonoids, lignin, and mucilage, which contribute to its therapeutic properties. These findings substantiate the traditional medicinal applications of ajwain, particularly in gastrointestinal and respiratory treatments. &lt;strong&gt;Conclusion:&lt;/strong&gt; The study provides essential diagnostic markers for quality control and standardization in herbal medicine, laying a foundation for future pharmacological investigations.&lt;/p&gt;
