Agada is one of the eight branches into which ayurveda medicine is traditionally divided. Literally, gada means a disease and agada means any agent which makes the body free from disease; however the term agada is used specifically for the branch of medicine dealing with toxicology, the description of the different types of poisons, and their antidotes. [1]
Agada Tantra is defined as a section of toxicology that deals with food poisoning, snakebites, dog bites, insect bites, etc. [2] The school of toxicology was founded and expounded upon by Kashyapa, also known as Vriddhakashyapa, a contemporary of Atreya Punarvasu. He lived in Taksashila in what is now Pakistan. His text was called the Kashyapa Samhita. This, however, is a different book than the Kashyap Samhita of pediatrics. This text is not available now but the references of this text are found mentioned in different commentaries. Some other texts written by Alambayana, Ushana, Saunaka, and Latyayana were known to exist. However except for references to them, the original texts are no longer available. [3] [4]
The traditional practice of toxicology is still practiced by different families of vishavaidyas (poison doctors), who specialize in toxicology. However, their knowledge is limited compared to the knowledge possessed by the earlier ayurvedic physicians. In ancient times, it was the job of Vishavaidyas to protect members of the royal family from being poisoned, as well to poison enemies of the kings. [5]

Ayurveda is an alternative medicine system with historical roots in the Indian subcontinent. It is heavily practiced in India and Nepal, where around 80% of the population report using ayurveda. The theory and practice of ayurveda is pseudoscientific.
Charaka was one of the principal contributors to Ayurveda, a system of medicine and lifestyle developed in ancient India. He is known as a physician who edited the medical treatise entitled Charaka Samhita, one of the foundational texts of classical Indian medicine and Ayurveda, included under Brhat-Trayi.
Vāgbhaṭa (वाग्भट) is one of the most influential writers, Scientist, Doctor and advisor of ayurveda. Several works are associated with his name as author, principally the Ashtāṅgasaṅgraha (अष्टाङ्गसंग्रह) and the Ashtāngahridayasaṃhitā (अष्टाङ्गहृदयसंहिता). The best current research, however, argues in detail that these two works cannot be the product of a single author. Indeed, the whole question of the relationship of these two works, and their authorship, is very difficult and still far from solution. Both works make frequent reference to the earlier classical works, the Charaka Samhita and the Sushruta Samhita. Vāgbhaṭa is said, in the closing verses of the Ashtānga sangraha to have been the son of Simhagupta and pupil of Avalokita. His works mention worship of Cows and Brahmanas and various Vedic Gods, he also begins with a note on how Ayurveda evolved from Brahma. His work contains syncretic elements.
Saṃhitā literally means "put together, joined, union", a "collection", and "a methodically, rule-based combination of text or verses". Saṃhitā also refers to the most ancient layer of text in the Vedas, consisting of mantras, hymns, prayers, litanies and benedictions.
The Bower Manuscript is a collection of seven fragmentary Buddhist Hybrid Sanskrit treatises found buried in a Buddhist memorial stupa near Kucha, northwestern China.

Agnivesha is a legendary rishi (sage) in Hinduism, reputedly one of the earliest authors on Ayurveda. He is described to have codified the knowledge of his preceptor, Atreya, and arranged it in the form of a treatise, named the Charaka Samhita.
The Charaka Samhita is a Sanskrit text on Ayurveda. Along with the Sushruta Samhita, it is one of the two foundational texts of this field that have survived from ancient India. It is one of the three works that constitute the Brhat Trayi.
The Sushruta Samhita is an ancient Sanskrit text on medicine and surgery, and one of the most important such treatises on this subject to survive from the ancient world. The Compendium of Suśruta is one of the foundational texts of Ayurveda, alongside the Charaka-Saṃhitā, the Bhela-Saṃhitā, and the medical portions of the Bower Manuscript. It is one of the two foundational Hindu texts on the medical profession that have survived from ancient India.
Kashyap Samhitā, also known as Vriddha Jivakiya Tantra is a treatise on Ayurveda attributed to the sage Kashyapa.
Sushruta, or Suśruta is the listed author of the Sushruta Samhita, a treatise considered to be one of the most important surviving ancient treatises on medicine and is considered a foundational text of Ayurveda. The treatise addresses all aspects of general medicine, but the impressive chapters on surgery have led to the false impression that this is its main topic. The translator G. D. Singhal dubbed Suśruta "the father of plastic surgery" on account of these detailed accounts of surgery.
In Ayurvedic medicine, the compilation of traditional ancient Indian medicine practice is called rasaśāstra(रसशासत्र ), which details processes by which various metals, minerals and other substances, including mercury, are purified and combined with herbs in an attempt to treat illnesses.

Putana disguises as a young, beautiful woman and tries to kill the god by breast-feeding poisoned milk; however Krishna sucks her milk as well as her life via her breasts. Putana is also considered as a foster-mother of Krishna as she breast-fed him. By offering her milk, Putana had performed "the supreme act of maternal devotion", in the shadow of her evil motives. The legend is told and retold in Hindu scriptures and some Indian books, which portray her variously as an evil hag or a demoness who surrendered herself to Krishna, though she initially came with evil motives.
