The strength of any herbal formulation depends on the delivery of phytoactives to an effective level. This limitation can be overcome by development of novel drug delivery systems, which ensure optimized drug delivery, enhanced bioavailability and better stability of phyto constituents for better therapeutic effects. Several novel herbal delivery systems have been successfully developed in recent years like liposomes, phytosomes, solid-lipid nanoparticles, ethosomes, microemulsions and various other vesicular systems. Transfersomes are vesicular drug delivery system having almost same structure like liposomes, but with better skin penetration properties to deliver the drugs at deeper skin tissues. Transfersomes are better drug delivery agents due to their ultradeformable structure.
