ABSTRACT

Background: Colon-targeted herbal therapeutics have emerged into the limelight as a consequence of their natural safety profile and multi-target pharmacology being applied in the treatment of inflammatory bowel disease, colorectal cancer and microbial infections. However, most of the herbal compounds are typified by poor stability, low solubility and degradation in the upper gastrointestinal system thus restricting their treatment ability. Nanoformulations strategies offer the possible solution of maintaining phytochemicals during delivery, increasing adhesion at the mucus, and delivering to the colon with controlled delivery or stimuli-sensitive delivery.

Pharmacognostic Basis: The phytochemical composition and bioconversion with colonic microflora are the most important knowledge of the pharmacognostic properties of the botanical identity of the plant, which is essential to select the appropriate actives of the plant.

Formulation Strategies: Polymeric nanoparticles, lipid-based carriers and polysaccharide-triggered systems are such sophisticated nanotechnology platforms that have demonstrated improved delivery efficacy and bioavailability.

Conclusion: These nanoformulations have been demonstrated as having a higher anti-inflammatory, anticancer, antimicrobial and antioxidant activity in in vitro and in vivo studies that render these nanoformulations next-generation therapeutic in colon-targeted therapy.

Keywords: Colon targeting, herbal compounds, nanocarriers, pharmacognosy, controlled release, phytochemicals.
