We have already seen that how ayurveda was passed on to sages on the earth. Although it may seem that Ayurveda is only one science, but the fact is that Ayurveda has been divided into branches, just like modern science of medicine. Traditionally the science of ayurveda has been divided into eight branches which are as follows:
1) Kayachikitsa(General Medicines)
2) Kaumarbhritya(Obstetrics and Paediatrics)
3) Graha or Bhootvidya(Diseases due to unknown causes)
4) Shalakyatantra(E.N.T. and Ophthalmology)
5) Shalyatantra(Surgery)
6) Agadtantra(Toxicology)
7) Rasayantantra(Rejuvenation Therapies)
8) Vajikarantantra(Problems associated with sex and related diseases and problems like infertility in both men and women)
It is believed that there were separate texts written on each of these branches; but they are unavailable now. There were Vaids specialising in respective branches in that era, just like specialist doctors in today's time. Texts on kayachikitsa and shalyatantra are still available in present time. On reading these texts one is amazed at the amount of knowledge of human anatomy and physiology,our acharyas had at that time.
Texts prominently available are Charaksamhita which is predominantly on Kayachikitsa and Sushrutsamhita which deals mostly with surgical cure of diseases. By reading these texts one gets to know that whatever diseases which are encountered in today's times have already been mentioned in ancient texts along with their causes and their treatment. Moreover not only physical but also psychological causes of the diseases have been described by the sages. Psychosomatic diseases ; the branch which is still considered to be developing by the modern science was well known since long time by Indian physicians. The exact pathology of the disease is also described properly in texts.
From the texts it is evident that vaids used to perform various surgeries like appendix, hernia and above all plastic surgeries with great efficacy. Plastic surgery which is thought to be the invention of modern medicine is known to Indians since long.
Ancient Indians knew the technique of preservation of dead bodies and performed their dissections to learn about the anatomy. They have give the exact number of nerves and blood vessels in human body.
Thus, it is evident that the science of Ayurveda was enjoying its Golden period in ancient times and it still has answers to various questions which present day modern science is unable to solve. It is up to us that how much we believe in this gift of our ancestors and again bring the glory days of Ayurveda back and prove its efficacy to the whole world.
