Herbal medicine is central to Indian medicinal treatment, which has been
known as Ayurveda traditionally. There are hundreds of herbs that have the
qualities to treat several kinds of diseases, even critical and chronic ones.
Importantly, these herbs have hardly any side effects. Herbal medicine is
manufactured from herbal extracts. Hence, the method of extracting herbal extracts
assumes high importance in manufacturing herbal medicines.
There are several methods for extracting herbs. However, the novel drug delivery
system (NDDS)-nanotechnology has been gaining popularity as a method to extract
herbal extracts. NDDS offers miraculous promises as it is a complete processing
system that combines the methods of drug formulation (pharmaceutics),
biochemistry, molecular biology, and process and technology. In this method, a
nano-sized drug release system is used to transmit medicines on the targeted parts
of the human body safely. NDDS serves many purposes, such as it minimizes the
requirement of frequent supervision to conquer refusal, enhances the remedial
worth, minimizes toxicity, and rises bioavailability.
There are many advantages to the targeted drug release system, such as it reduces
the frequency of the dosages taken by the patients, has a more uniformed effect of
the drug, reduces any possibility of side effects, and controls fluctuation in
circulating drug levels.
