Valerian flower is more subtle than valerian root, but still has significant relaxing qualities for the mind and body. There is the smell of the earth, with a subtle floral, overtone. It’s really kind of primal, sensual scent. I would use this before bed when I wanted to chill and relax and sink into my body, quieting the chatter of the mind. Or on a beach or wilderness vacation, so I would have a break from worrying about my responsibilities back home and I could again sink into body, and the here and now. I would not operate heavy machinery or drive much after smelling a lot of this hydrosol.
For general anxiety, mixing with the Lemon Balm or Lavender might be recommended. This product is limited in quantity, and is expected to sell out quickly.
