Interesting information about AyurvedaAyurveda is one the oldest systems of Medicine. A lot of Ayurveda formulations contain metals and the branch which deals with this ancient alchemy & pharmacology is called as RasaShastra.
The development of RasaShastra (in 7th century AD) has revolutionized Ayurveda. Various pharmaceutical techniques convert the drug into very fine, absorb-able, non-toxic and therapeutically more effective. Bhasma formulations are considered the best example of this.
Nanotechnology is the technology of 21st century. Nano-medicine is the medical application of nanotechnology. It is the manipulation of matter with at least one dimension sized from 1 to 100 nano-meters. Bhasmas possess the pharmaco-dynamics similar to nano-medicines and the particle size of the bhasmas range between 1 to 100 nano-meters. Hence, nano-particles have been used as effective medicine since centuries in Ayurveda. Researchers are trying to use Gold and silver nano-particles to treat various diseases while Gold bhasma & silver bhasma has been used in Ayurveda since ages.
(Just now I have read this in a report. I would like to know the details of nano-medicines and its use in Ayurveda from Members who have in-depth knowledge of the issue.)
