{{ToBeEdited}}

Acharya Charaka fondly known as The Father of Medicine has great contributions to the field of Ayurveda. He is also well known as the author of Charaka Samhita, actually, the redactor of Charaka Samhita, and the treatise is originally known as Agnivesha Tantra. This Charaka Samhita concentrates more vividly on internal medicines and external applications rather than invasive procedures, thus, it is said that Acharya Charaka being from the school of Punarvasu Atreya thoughts is more focused on the Kaya Chikitsa() branch of Ayurveda. Hence the name Father of medicine.

== Nirukti ==
चरएव स्वार्थे क संज्ञायां कन् वा । चरे दूतभेदे । 

(vachaspatyam pg.2900)

A physician who wanders from one place to another providing medical advice and treatment is termed a Charaka.

== Period ==
Acharya Vagbhata author of “Ashtanga Hriddaya” (ayurvedic treatise), mentioned Charka in his texts suggesting he lived before his time period.

Acharya Charaka lived from around 100 to 200 BCE. Acharya Charaka was the son of Vishuddha Krishi and a disciple of Vaishampayana Rishi. His birthplace is not known nor mentioned in any treatise, but there are references quoted regarding the Himalayas, panchanandpura, etc by him which are situated around northwestern areas of India. Thus, a loose conclusion can be drawn about the birthplace of acharya Charaka.

== History ==
The present treatise of Charaka Samhita has a long history, according to different Ayurveda Literature, Lord Brahma (the Creator) passed on the Knowledge of Ayurveda to Daksha. He then passed on this gem of knowledge to the twin Physician of God well known as The Ashwini Kumaras. Ashwini Kumaras further passed this knowledge to the King of God Indra. Now, this Knowledge of Ayurveda descended to earth through Rishi Bharadwaj who learned this Knowledge from Indra for the purpose of treating people suffering from various diseases. Rishi or Sage Bharadwaj imparted this divine knowledge to his Disciple Punarvasu Atreya.

Punarvasu Atreya or known as Atreya imparted his knowledge to his disciples namely, Agnivesha, Bhela, Jatukarna, Parashar, Harita, and Ksharpani. These Rishis or Sages wrote their version of Atreya’s teachings. Agnivesha composed Agnivesha Tantra (treatise) which later was redacted by Acharya Charaka. This Agnivesha tantra being one of the oldest treatises was mutilated over time, thus the original work is not found. Later acharya Charaka found, gathered these written pieces, redacted Agnivesha tantra, and named Charaka Samhita. Although appropriate credits have been given to Atreya in the form of the below verse present at the beginning of every chapter.

इति ह स्माह भगवानात्रेयः|| 

This above verse literally means, “thus said by God Atreya”

The adhayayas or chapters are orated by Atreya to his Shishya or disciple Agnivesha. Thus, binding to ''Guru Sishya Parampara''(precisely a part of knowledge transfer), these verses are in the form of Questions stated by Agnivesha to Punarvasu Atreya, and written down by Agnivesha as dictated or stated by his Guru(teacher precisely) Atreya.

   “''Agniveshakrute Tantre  Charak pratisanskrite''”

This means that the original treatise is written by Agnivesha and put together or organized well by Acharya Charaka.

The below chart represents the hierarchy of the Charaka Samhita and how the Knowledge of Ayurveda came into existence, how it got to Acharya Charaka and known to human beings.



Although, the Charaka Samhita was further mutilated and lost over time. A scholar from Kashmir named Dridhabala, a resident of then Panchanandpur found Charaka Samhita in wretched condition, restored it, and wrote/ added a few chapters to the treatise. He added a total of 41 chapters to this existing treatise. The version we read today is this version of acharya Dridhbala’s redactions of Charaka Samhita. (char.sidd.12.37,38)

== Commentaries on Charaka Samhita | ''teeka'' ==
Teeka in Sanskrit means to comment or a note. Thus, there are few commentators who tried to clarify in detail the verses which needed an explanation for further understanding.

Chakrapani wrote Ayurveda Dipika. 

Gangadhar Sen wrote Jalakalpataru.  

Jejjata wrote Nirantarapada Vyakha.

Bhattara Harischandra wrote Chrakanyasa.(first commentator to write after the redaction process by Dridhbala)
