Primary Actions

  • Retains a more clearly astringent raw-seed character than the already-live stir-fried sibling ... both calm the spirit, but the preparation form still matters.

Secondary Actions

  • Tian Wang Bu Xin Dan ... Suan Zao Ren supports Heart-Yin and blood nourishment in deeper deficiency insomnia patterns.

Classical References
