A Review on Herbal Nanosuspension from Herbal Extract

Abstract

Herbal nanosuspensions have emerged as a promising strategy to overcome the challenges associated with the poor solubility and bioavailability of many herbal extracts. This review explores the advancements in herbal nanosuspension research, highlighting their preparation methods, characterization, and potential applications

Nanosuspension, which consists of nanosized herbal drug particles dispersed in a liquid medium, offer increased surface area, enhanced dissolution rates and improved drug delivery. Various techniques including high pressure homogenization, media milling and antisolvent precipitation have been employed to formulate stable nanosuspension from a wide range of herbal extract.

Nanosuspensions, which consist of nanosized herbal drug particles dispersed in a liquid medium, offer increased surface area, enhanced dissolution rates, and improved drug delivery. Various techniques, including high-pressure homogenization, media milling, and antisolvent precipitation, have been employed to formulate stable nanosuspensions from a wide range of herbal extracts.

The resulting nanosuspensions have demonstrated improved therapeutic efficacy in various in vitro and in vivo studies. This review also discusses the challenges and future directions in the development of herbal nanosuspensions, emphasizing the need for standardized protocols, stability studies, and clinical trials to fully realize their potential in herbal drug delivery.
