Hi, I have not taken this herb but this is what I have read about it.
Valerian may be indicated for the relief of insomnia, stress-related anxiety, and nervous restlessness. Some people, however, experience adverse reactions to valerian. Rather than feeling the calming or sleep-inducing effects, they suddenly feel nervous, anxious and restless after taking the herb and may experience heart palpitations.
May I suggest that anytime you are looking at adding something to your med regime you do talk it through with your physician.
Take care and stay well,
