Ayurveda teaches us that when we experience any sort of disorder we're experiencing an imbalance of the elements in our mind and body. And while this may be something that is easy enough to relate to a basic physical imbalance like acne (too much of the fire element) or constipation (too much of the air element), something as emotionally complicated as depression can be harder to relate to a medical system like Ayurveda.
But what is significant about Ayurveda as a system is that it doesn't just teach us how to resolve illnesses; it teaches us how to live in greater balance so as to avoid illness in the first place. With this in mind, if a person were to embrace an Ayurvedic lifestyle in accordance with a simple diet of natural foods and their individual constitution, they will be far less likely to experience the emotional imbalances that define a bout of depression.
While other interventions may be necessary to alleviate symptoms of depression as well, it is still helpful to follow Ayurveda's guidelines for a balanced lifestyle. In time, the symptoms will lessen and no longer be an issue.
