Pathology Under normal conditions, the doshas, tissues and waste products correspond to certain standards regarding their quantity, quality and function. However, this situation is not static, and due to several endogenous and erogenous factors, the doshas may become unbalanced, resulting in disease.
Every disease is related to an imbalance of the doshas.
