Schisandra berry · Wu Wei Zi
Schisandra chinensis (Turcz.) Baill. · Mature fruit
Name and part used
A woody climber with oval leaves and clusters of red berries; dried fruits are wrinkled and dark red-purple.
Traditional context
Northern Wu Wei Zi generally refers to mature Schisandra chinensis fruit. HKBU describes vines at forest edges and streamside thickets, ripening in late summer to autumn. Other Schisandra species exist, so scientific identity and origin matter.
Modern evidence
Astringing, fluid-generating, and kidney-tonifying are traditional descriptions. Lignans and early research do not establish clinical benefits for liver, heart, asthma, or infection.
Safety
It may affect drug-metabolizing enzymes, and HKBU notes toxicity. Do not combine casually with prescription drugs, especially narrow-therapeutic-index medicines; ask a pharmacist or clinician.
Pairing in reference texts
Wu Wei Zi is part of Sheng Mai San with ginseng and Mai Men Dong. Classical records document the formula structure, not compatibility with modern medicines.

Cultivated in Northeast and North China, Henan and etc. The medicinal materials are produced in Liaoning, Heilongjiang and Jilin. The medicinal materials are mainly produced in Hebei, Inner Mongolia and etc Harvest and processing as recorded: Collected when fruits mature in autumn, sun-dried directly or after steaming, removed pedicle and impurities

Open habitat and season source ↗FROM PLANT / SOURCE HABITAT TO DRIED MATERIAL · REFERENCE WORKFLOW
- Harvest ripe clusters in autumn according to the growing region; authenticate Schisandra chinensis against related species.
- Remove pedicels and foreign matter with clean equipment; wash only if the facility process specifies it to avoid prolonged moisture.
- HKBU records direct drying or steaming followed by drying. Steaming is facility processing, not a self-treatment recipe.
- Control moisture, grade, and record the lot; store cool and dry away from light to limit deterioration.
These are post-harvest study notes, not directions to prepare a remedy for self-treatment. Processing reference ↗
