மருத்துவ நூலை நன்கு கற்ற மருத்துவர், நோயாளியின் நோயைப் போக்க முயலும்போது, நோயாளியின் வயது, அந்நோய் வந்திருக்கும் காலம், நோயைப் போக்கத் தனக்குத் தேவையாகும் காலம் ஆகியவற்றை எண்ணிச் செயல்பட வேண்டும்.

நோயாளியின் வயது, நோயின் தன்மை, மருத்துவம் செய்வதற்குரிய நேரம் என்பனவற்றை எல்லாம் மருத்துவம் கற்றவர் எண்ணிப் பார்த்தே செயல்பட வேண்டும்

மருத்துவ நூலைக் கற்றவன், நோயுற்றவனுடைய வயது முதலியவற்றையும், நோயின் அளவையும், காலத்தையும் ஆராய்ந்து செய்ய வேண்டும்.

The learned (physician) should ascertain the condition of his patient; the nature of his disease, and the season (of the year) and (then) proceed (with his treatment)

This verse from Thiru Kural emphasizes the importance of thoughtful and comprehensive consideration in providing medical care. The learned physician is advised to consider not just the disease itself, but also the patient's age, the nature of the disease, and the time of the year before proceeding with the treatment. The age of the patient can play a significant role in how a disease manifests and how the patient responds to treatment. The nature of the disease refers to its severity, symptoms, and potential complications. The time of year is also important as some diseases are seasonal and the body's response to treatment can also vary depending on the season. The verse encourages physicians to take a holistic approach to healthcare. It implies that effective treatment is not just about addressing the disease but understanding the patient as a whole, which includes their age, the characteristics of their disease, and the influence of external factors like the season. In other words, a skilled physician must be observant, thoughtful, and considerate of all these factors to provide the most effective treatment. This verse underscores the wisdom of the ancient Tamil people in medical science and patient care.
