Background: Agnimantha is a constituent of the bṛhatpañcamūla (the roots drugs of 5 tree species) which in turn is a part of daśamūla used in Ayurvedic pharmaceutical practices. Traditionally, the concept of bṛhatpañcamūla envisages the usage of root/ root bark of these tree species. By and large, use of stem bark came into vogue many decades ago for this sub-group of daśamūla. Going by descriptions in Ayurvedic lexicon of medicinal plants- two species are considered as Agnimantha viz. Clerodendrum phlomidis L.f. (Fam.: Lamiaceae) and Premna integrifolia L. (Syn. Premna serratifolia L) (Fam.: Lamiaceae). Objective: With an objective to address sustainability concerns associated with use of root or stem bark a comprehensive study was carried out on bṛhatpañcamūla group. This study kept the anti-inflammatory profile of candidate extracts in the centre-stage. As a part of this study, comparative assessment of two species used as Agnimantha was also carried out. Study Methodology: Different plant parts (Root bark, Stem bark, Leaves and Young roots) of C. phlomidis and P. integrifolia were collected from different parts of India. Each sample was extracted successively into four solvents. These extracts were evaluated for their anti-inflammatory profile using a battery of in-vitro assays, involving inhibition of regulatory enzymes like 5-lipoxygenase (5-LOX), cyclooxygenase 1&2 (COX-1 & COX-2) and analysis of the expression of pro- and anti-inflammatory cytokines in LPS-stimulated RAW 264.7 cells.Result and Conclusions: Both the species were observed to exhibit anti-inflammatory activity of varied degrees in this study. However, the sample of 12 months old roots of P. integrifolia was found to possess profound effect on all markers of inflammation. This sample was followed by 36 months old roots of C. phlomidis in terms of anti-inflammatory profile. Basing on these observations, the study suggests the use of 12 months roots of P. integrifolia (often referred to as Bṛhat-agnimantha) as part of daśamūla. Since the harvesting cycle is of 12 months, it is possible to produce the roots using High-Density Short-Term plantation protocols to address the sustainability concerns associated with use of root or stem bark.
