Can valerian root cause a late period?

Valerian root is primarily used as a herbal remedy for anxiety and sleep disorders, and there is limited scientific evidence linking it directly to menstrual cycle changes. However, any significant alteration in stress levels or hormonal balance can potentially affect the menstrual cycle. If valerian root affects your sleep or stress levels, it might indirectly influence your period. If you have concerns about a late period, it's best to consult with a healthcare professional.
