Material
Medica
The material medica of Ayurveda is very extensive. Herbal, animal and
mineral substances were used as medicine. Various methods and instruments
were used to prepare drugs and to isolate active principle from organic
material. Weighing balances and measuring jars were used to take exact
quantity of materials for preparation of medicines. Apart from oral there
were other methods of administration of drugs like external applications,
vasti-injection through rectum or urethra, Dhumapana – inhalation, Nasya
karma – snuffing and Dhupana – fumigation of wounds and ulcers.
Animal
Medicine
Ayurveda not only dealt with diseases of human being but also that of animal
kingdom and plants. Alleviating the sufferings of all living being was the
goal of Ayurveda. Gouthama’s ‘Gavayurveda’ is a book, which deals only with
medical aspects of cows. ‘Salihotra Samhita’ is a very old and famous text
on horses. ‘Aswavaidyakam’ of Jaya Dutta Suri and ‘Aswasastram’ of Nakula
were based this text. The former is a voluminous text with 68 chapters and
deals with the classification of horses and their characters, salient
features, diseases and treatment. In Nakula’s text (‘Aswasastram’) many
information regarding various aspects of horses are compiled together. It
contains on the anatomical structure of horses, which reveals the sound
knowledge that was available at that time. Elephants were used for carrying
loads and in war. ‘Hastyayurveda’ written by Palakapya is a text on
treatment of elephants.
Vrikshayurveda
This gives us information about plants. We get information on this branch of
Ayurveda scattered in many textbooks. A chapter in Sarangadhara’s medical
text ‘Upavana Vinodam’ deals with this branch. Susrutha Samhita, Upasakaram
of Sankara Misra, Brahat Samhita and Manu Samhita also contain knowledge
regarding botanical sciences. In these books there are references of
creating new species of plants with required characters. It is really
surprising that our ancestors had thought two thousand years ago of the
genetic techniques practiced by botanists today.
Siddha
Medicine
The Siddha system of medicine is the system of medicine popular in South
India especially in Tamil Nadu state. According to mythological sources sage
Agasthya is considered as the originator of Siddha medicine. The science of
chemistry was well developed in the Siddha system. They used many metallic
compounds including mercury and arsenic effectively in practice. Mercury was
used in the treatment of venereal diseases and arsenic in the treatment of
leprosy. ‘Siddhanar Krithikal’ written by Siddhars in Tamil is a treasure
house of knowledge of medicine, chemistry and related subjects. There are
more than 500 medical works containing over 3000 valuable formulae. Composed
of five lakh stanzas. These books written thousand of years before Christ,
reveal the depth of knowledge Indians had in chemistry.
