It is a belief in Ayurveda that the balance of these gunas is fundamental to physical health of the body. For example, if the three gunas (or Doshas in Ayurved) are in perfect harmony, your internal resistance to disease grows to a point where nothing can penetrate and the body is disease free.

In fact there is a powerful herbal medicine in Ayurveda called Triphala which is known to be "Tridoshic", meaning it has the potential to balance the three gunas in the body, keeping it healthy and disease free.
