Ayurveda Nighantu is a medical dictionary of drugs/herbs used in Ayurveda, the word Nighantu means ‘treasure’. Another early term for a medical dictionary is Dravya Gana Sangraha Kosha. The first compilation of medical substances based on their nomenclature was done by Amarasimha in Amarakosha, but he did not describe the properties of these substances. Several centuries earlier, Charaka and Sushruta had described and classified different medical substances but these works formed only a part of their Samhitas, which is why these texts do not come under the category of Nighantu.
The oldest known Nighantu is Dravyaguna Sangraha by
Chakrapanidalla. He followed the same classification of substances as that
followed by Charaka and Sushruta. Then comes Dhanvantari Nighantu although this
medieval text was not written by Dhanvantari and it is dated somewhere about
1150 CE. The author has described in it the properties of mercury, five types
of magnets and different metals along with the pharmacodynamics of herbs and
trees and their uses in various diseases. Raja Nighantu is another important Nighantu,
which is also called Abhidhanachudamani. This was written by Narahari who
belonged to Kashmir. He used some vernacular names from Kannada, Marathi and
Telugu languages.
