Shital Shivaji Chavan and Purushottam Sahadev Lahane*

ABSTRACT

The herbal medicines have been popularized throughout the globe since ancient time. Several plants based therapeutic moiety have been produced through new approaches. Many herbal bioactive have several health benefits but have limited therapeutic potential due to short biological half-life and moderate bioavailability profile. To improve such therapeutic issues nanocarriers were introduced such as phytosomes, ethosomes, transfersomes, herbal transdermal patches, nanoemulsion. They have the ability to maximize the efficacy of herbal bioactives by improving their solubility, absorption profile, lowering dose and side effects. Nanoemulsion is a mixing of oil, surfactant, co-surfactant and drug that can spontaneously form oil-in-water micro/nanoemulsion when mixed with water under continuous stirring. The solubility and bioavailability of nanoemulsion is achieved by its lipophilic nature and size reduction. The nanoemulsions can vehicle the herbal bioactive to the particular target site and offer sustained release of drug. The present review describes the importance of nanoemulsions for delivery of herbal drug.
