HARIDRA VARIETIES USED IN AYURVEDA FORMULATION-AN OVERVIEW

Haridra, encompassing several species within the genus Curcuma (Zingiberaceae family), is a vital component of traditional Ayurvedic medicine. This research focuses on a comparative analysis of four species of Haridra: Curcuma longa (turmeric), Curcuma aromatica (wild turmeric), Curcuma caesia (black turmeric) and Curcuma zedoaria (zedoary). These species, while sharing specific common characteristics, display distinct differences in their morphology, chemical composition, and therapeutic applications. The study investigates the morphological features of each species, including the rhizome colour, texture and aroma, which are essential for their identification and use in traditional formulations. Additionally, each species' chemical composition is analysed, focusing on curcuminoids, essential oils, and other phytochemicals known for their anti-inflammatory, antioxidant, antimicrobial, and digestive properties. The aim is to establish a correlation between the chemical profiles of each species and their traditional Ayurvedic uses, such as promoting skin health, enhancing digestion, and providing pain relief.
