• Promotes high quality sleep
      • Enhances mood

      • Supports brain function


Paeonia lactiflora, also known as white peony roots, is one of the most common herbs in Traditional Chinese Medicine. It is used for treating insomnia, promoting mental focus, and maintaining immunity.
As one of four herbs in TCM herbal formulas, this herb is part of Si Ni San, which supports sleep quality and reduces mental fatigue.
Researchers have shown that paeoniflorin [1] can affect adenosine signaling, which is critical to sleep homeostasis, in preclinical studies.
Aside from that, paeoniflorin has been found to support brain repair and protection processes (such as BDF-i, NGF, and BDNF), counter chronic stress, influence learning, and promote a healthy mood*.
