Nano-encapsulation of herbal bioactive: A next-generation approach for anti-inflammatory therapy

Abstract

Although inflammation is a basic biological reaction to damage or infection, persistent or unchecked inflammation is the root cause of many illnesses, including as cancer, diabetes, heart disease, and arthritis. Even though there are many synthetic anti-inflammatory medications on the market, prolonged use of these medications is frequently linked to side effects and low therapeutic efficacy. By altering molecular pathways like NF-κB, COX-2, and NLRP3 inflammasome signalling, herbal bioactive like curcumin, quercetin, resveratrol, and boswellic acids have shown strong anti-inflammatory potential. However, their clinical translation is limited by their quick metabolism, low bioavailability, and poor solubility. A next-generation approach to overcoming these obstacles is nano-encapsulation, which improves the solubility, stability, and targeted delivery of herbal bioactives. The pharmacokinetic profiles and controlled release of chemicals originating from plants can be improved by using nanocarrier systems such liposomes, polymeric nanoparticles, solid lipid nanoparticles, and nanoemulsions. Additionally, ligand conjugation and surface modification allow for site-specific distribution to inflammatory regions, reducing systemic toxicity and enhancing therapeutic results. Recent developments in nano-encapsulation techniques for herbal anti-inflammatory drugs are thoroughly reviewed in this paper, which also highlights formulation techniques and mechanisms of action. Current issues with clinical translation, large-scale manufacturing, and regulatory approval are highlighted, along with the interaction between nanoparticle design and biological response. The combination of nanotechnology with phytotherapy has created a revolutionary platform for the safe, efficient, and long-term treatment of inflammatory diseases: nano-encapsulated herbal bioactive.
