Herbals have been explored worldwide from ancient times for their innumerable
therapeutic applications. Despite the advantages, phytomedicines encounter several
drawbacks like toxicity, lower bioavailability, stability problem and patient compliance.
To overcome these constraints researchers came up with the introduction of Novel Drug
Delivery Systems (NDDS). These included polymeric liposomes, nanolipid carriers, colloidosomes,
solid lipid nanoparticles, aquasomes, niosomes, proliposomes, nanocapsules,
ethosomes, phytosomes, nanoparticles, nanoemulsions, and transferosomes.
Nanotechnology is being ventured as an emerging trend in the field of medicines eliciting
improved therapeutic benefits. It reflects the interface between new technology and
herboceuticals. These upcoming herbal formulations are being patented too. Since
nanotechnology is slowly creeping into every aspect of life, a concern has been generated
related to the human safety. Hence, the present time demands the regulations to be
set up for nanomaterials. In this paper, an effort has been made to compile various
herbal nanoformulations and patents and a glance on the regulatory aspects of various
regulatory bodies on nanotechnology have been provided.
