Abstract
Background: Herbal medicines have been extensively used to treat diseases since the prehistoric era, but written records date back more than 5,000 years only. All civilizations developed their knowledge of herbal medicines in a well-ordered system, such as Ayurveda, Unani, Traditional Chinese Medicine, etc. The interest in traditional medicine declined after the discovery of modern medicine. However, in the 21st century, herbal medicines are staging a comeback as the dangers and limitations of modern medicine have become more apparent and herbal medicines are viewed as a balanced and moderate approach to healing.
Methods: This review includes the nanoformulations of phytoconstituents and extract. Advancements in analysis and clinical research prove the efficacy of nano-herbal medicines in preventing and treating diseases. This review is mostly about how nanotechnology can be used to help herbal medicines work better.
Results: The major problems with herbal medicines are their poor solubility and stability. New technological advancements are capable of removing the problems associated with herbal medicine. Novel drug delivery systems such as microemulsion, liposome, niosome, and nano-drug delivery systems are used to enhance the safety and efficacy of herbal medicines.
Conclusion: Nanotechnology has significant merit for herbal medicines, such as improving solubility, bioavailability, pharmacological activity enhancement, and stability enhancement.
