Prepared Stemona Root
- Chinese
- 制百部
- Pinyin
- Zhi Bai Bu
- Latin
- Radix Stemonae Praeparata
Known in TCM as Zhi Bai Bu (制百部), this bitter and sweet, slightly warm herb enters the Lung. Traditionally, it moistens the Lung and stops cough ... prepared Bai Bu is used for chronic cough, lingering dry cough, and cough from Lung weakness or mixed dryness-phlegm patterns, most often applied for cough, dry cough, and productive cough. Modern research has identified Stemona among its active constituents.

Traditional Use
Primary Actions
- Moistens the Lung and stops cough ... prepared Bai Bu is used for chronic cough, lingering dry cough, and cough from Lung weakness or mixed dryness-phlegm patterns.
- Reduces irritancy compared with the raw root lane ... processing supports gentler internal use when the goal is cough relief rather than external pest-killing use.
- Still addresses parasite or lice traditions secondarily ... but the prepared form is primarily a cough-facing medicinal page.
Secondary Actions
- This page should stay distinct from the raw Bai Bu sibling ... the prepared form is darker, more clinically internal-use-facing, and less like a raw insecticidal root display.
- Compared with herbs such as Zi Wan, prepared Bai Bu is often chosen for a softer moistening cough-lane rather than a stronger phlegm-expectorant emphasis.
Classic Formulas
- Bai Bu Wan lineage ... classical antitussive use of Bai Bu for chronic cough.
- Clinical pairings with Zi Wan and Jie Geng ... common logic for stubborn cough requiring both moistening and phlegm resolution.
- Bai Bu-based syrup and decoction traditions ... often aimed at prolonged post-infectious or consumptive-style cough.
Classical References
- Traditional Chinese medicine describes Bai Bu as a Lung herb that stops cough and also kills parasites and lice.
- Prepared forms are commonly preferred when internal cough treatment is the main goal.
Modern Research
Active Compounds
- Stemona alkaloids ... the best-known characteristic constituents of the Bai Bu group
- Maistemonine-class alkaloids ... identified from Stemona japonica with anti-inflammatory relevance
- Additional root fractions with antitussive and anti-inflammatory activity ... reported across Stemona species
Studied Effects
- A 2021 review of Stemona species summarized traditional uses, phytochemistry, and pharmacology, including the longstanding cough-relieving role of Bai Bu resources (PMID 32726680).
- Stemona tuberosa alkaloids showed antitussive and central respiratory depressant effects, providing modern support for the traditional cough-suppressing use of the Bai Bu medicinal family (PMID 20219659).
- Maistemonine-class alkaloids isolated from Stemona japonica showed anti-inflammatory activity, adding species-specific support for the prepared Japanese Stemona lane (PMID 36913154).

Safety & Interactions
Cautions
- High doses or poor-quality Stemona material may cause nausea, vomiting, headache, or central nervous system effects.
- Evidence for prepared Bai Bu is often drawn from the broader Stemona medicinal family rather than from one standardized processed product.
