Ashwagandha is an Ayurvedic herb that is particularly useful for helping your body handle stress and fatigue. When your stress systems are more resilient, your body can focus on balancing stress hormones with sex hormones like estrogen and progesterone. Studies suggest that consuming ashwagandha may help improve symptoms of occasional anxiety and stress as well as support a beneficial response to stressful situations. Ashwagandha may also support better sleep and reduced inflammatory signaling in skin cells.
