Bai Zi Ren柏子仁
Platycladi Semen · Chinese Arborvitae Kernel · Biota Seed
Overview
An oily, sweet seed that feeds the Heart rather than sedating it: it nourishes Heart blood and yin so that sleep settles from within, and its richness also moistens a dry bowel — a useful combination in older or postpartum patients whose insomnia and constipation stem from the same depletion. Dry-frying reduces the oil and with it much of the laxative effect.

4 core actions
- Nourishes the Heart, calms the spiritInsomnia, palpitations, anxiety and forgetfulness where Heart blood and yin are insufficient rather than where fire is blazing.
- Moistens the intestines, moves the stoolDry, hard stool from blood or fluid depletion — in older adults, after childbirth, and during recovery from long illness.
- Restrains sweatingNight sweats accompanying yin deficiency, usually alongside other yin-nourishing herbs.
- The dry-fried form differsDry-frying reduces the oil content: choose it when the spirit needs calming but the stools are already loose, and use the untreated seed when the moistening laxative action is wanted.

Cautions
Rich and oily: unsuitable where there are loose stools, or phlegm-damp with copious sputum. Where the spirit needs calming but the bowels are already loose, the dry-fried form is the right choice. Not a sedative — it works by supplementing, so its effect on sleep builds over a course rather than in a single dose.
Contraindicated in pregnancy: Not a classical pregnancy contraindication — practitioner judgment applies, taking the moistening laxative effect into account
