Depression is often understood within the context of imbalances in the bodys three doshas which are vatha, pittha, and kapha. According to Siddha medicine principles, depression is believed to arise due to disturbances in these doshas, which affect both physical and mental health. Depression is known as Mano vatham or Mano noigal. The term mano refers to the mind, and vatham or Noigal refers to an imbalance or disorder. Therefore, Mano vatham or Mano noigal can be interpreted as a disorder of the mind.
