  7. Dear Doctor,

    My daughter had a major depressive episode 2 years back and was on antidepressant for 9 months. She is still being treated for anxiety disorder and on Lonazep 0.5 mg once a day.
    Still she is unable to come out of the sad feelings and depressed mood and complains of severe fatigue and exhaution all the time.Also, she suffers from sleep disorders and always anxious and stressed. This condition is severely affecting her studies and her routine.

    I was checking on few of the Ayurveda medicines and noticed that Vacha is used as one of the main ingredients. Is it safe to administer such Ayurveda medicines containing Vacha?

    Please clarify.

    Thanks
    S R Srikantiah
