This is a question I hear often in clinic, and the honest answer has more nuance than a one-line rule.
Ayurveda does not treat the mind as separate from the body, so a mood or anxiety complaint is always assessed alongside digestion, sleep, and general constitution — not as an isolated psychological issue.
When a patient is already on prescribed medication, my priority is safety: understanding what they are taking, checking for known herb-drug interactions, and coordinating rather than working around their existing care team.
Ayurvedic support can meaningfully reduce symptom burden and improve day-to-day functioning, but for moderate-to-severe presentations it works best as an adjunct to, not a replacement for, conventional psychiatric care.
Every patient's presentation is different, so this is general clinical guidance rather than a substitute for an individual consultation — Testing, Testing, would want to examine your specific history before recommending a protocol.
