On this page
1. Overview
Bǎi Zǐ Rén (柏子仁) — Platycladus orientalis seed — is one of the most important herbs for nourishing the Heart and calming the Shen. It belongs to the category of Herbs that nourish the Heart and calm the Shen. Unlike heavier mineral-based sedatives, Bai Zi Ren is a moistening, oil-rich seed that gently nourishes Heart Yin and Blood. It is widely used for insomnia, anxiety, palpitations and constipation in Blood-deficient or Yin-deficient patients.
