From the cypress that lives a thousand years, Bai Zi Ren nourishes heart blood to still a troubled mind and moistens the intestines for the dry constipation of elders. The evergreen's longevity earned its seed a place in every classical heart-blood insomnia formula — often beside its sour-jujube cousin.
