Charak Samhita
वाते पित्ते कफे चैव क्षीणे लक्षणमुच्यते। कर्मणः प्राकृताद्धानिर्वृद्धिर्वाऽपि विरोधिनाम् ॥५२॥
॥ Diagnosis of abnormal state of dosha॥ Any decrease in vata, pitta and kapha is thus indicated by a decrease in their natural functions or increase in functions of opposite dosha. (this is indicated by the properties associated with any of these dosha, for example, reduced unctuousness indicates a decrease in kapha, etc).
