Ayurveda has a long history of scientific background.The general concept of people is that the Ayurvedic drugs are slow acting,but the Herbomineral preparations known as Bhasma are the miraculous drugs.It is a real fact that these Drugs has a fast pharmacological action in target site.Now the concept is supported by a Research Paper published in Journal of Biomedical Nanotechnology Feb Issue.This is a reputed journal in the field of Nanotechnology published from US. This paper attracted the International attention of scientific community.The recent studies in the Dept of Rasa-Sashtra , Banaras Hindu University also claimed that the Bhasma (Herbomineral preparations) of Ayurveda works on the principle concept of Nano-medicine.Concept of reducing the particle size is mentioned in ancient Ayurvedic text Charak Samhita.“The studies have confirmed that Bhasmas, which are unique Ayurvedic metallic/mineral preparations are biologically produced nanoparticles (NPs) prescribed with several other medicines of ayurveda,” said associate professor, department of Rasa Shastra, Anand Chaudhary. Though, herbo-mineral formulations (bhasmas of metals and minerals) are used since seventh century, it was only assumed that these medicines have superior level of efficacy in comparison to other ayurvedic dosage forms. “Now, studies have also established that manufacturing methods of Bhasma are in tune of nanotechnology of modern era and bhasmas are nearer to nanocrystalline materials, similar in physico-chemical properties,” he added.It may be mentioned here that Chaudhary, along with Prasanta Kumar Sarkar of department of Rasa Shashtra, JB Roy State Ayurvedic College, Kolkata have come up with research paper on ayurvedic bhasma after a number of studies in the subject for the past two years. Also, Neetu Singh, research scholar, department of Rasa Shashtra, is also working on the potential of ‘lauha bhasma’ (Bhasma containing traces of iron) in therapeutics, using nanomedicine.All ‘bhasmas’ have some common properties like ‘rasayana’ (immuno-modulation and anti-aging quality) and ‘yogavahi’ (ability of drug carry and targeted drug delivery). These are prescribed in very minute dose (15 to 250 mg/day) and if prepared properly they are readily absorbable, adaptable and assimilate in the body without being toxic. “These attributes of bhasmas are comparable with the action of NPs in the body which are also biodegradable, biocompatible and non-antigenic in nature,” Chaudhary said while comparing their properties.
