Black Pepper Fruit
- Chinese
- 胡椒
- Pinyin
- Hu Jiao
- Latin
- Fructus Piperis
Known in TCM as Hu Jiao (胡椒), this acrid, hot herb enters the Stomach and Large Intestine. Traditionally, it warms the middle and disperses cold for epigastric or abdominal pain, vomiting, and diarrhea caused by interior cold, most often applied for abdominal pain, diarrhea, and nausea. Modern research has identified Piperine among its active constituents.

Traditional Use
Primary Actions
- Warms the middle and disperses cold for epigastric or abdominal pain, vomiting, and diarrhea caused by interior cold.
- Directs rebellious Qi downward and improves digestion when cold constrains the Stomach and upper digestive tract.
- Can be used externally for toothache or localized cold pain in small, focused applications.
Secondary Actions
- Hu Jiao should stay distinct from long pepper even though both share piperine-rich chemistry and warming digestive logic.
- As a food spice it is familiar, but the monograph concerns its stronger medicinal use in cold-pattern digestive states.
Classical References
- Traditional Chinese materia medica consistently places Hu Jiao among the hot internal-warming herbs for Stomach-Cold pain, vomiting, and diarrhea.
- Its use is narrower and hotter than ordinary culinary seasoning suggests.
Modern Research
Active Compounds
- Piperine
- Chavicine
- Volatile oils
- Sesquiterpene fractions
Studied Effects
- Review literature describes piperine as anti-inflammatory, antioxidant, antimicrobial, and bioavailability-enhancing, which helps explain the enduring interest in black pepper as a pharmacologically active warming spice (PMID 34996326).
- A classic review of black pepper and piperine also emphasized digestive-enzyme stimulation, shortened gastrointestinal transit time, and broad physiologic activity relevant to Hu Jiao's warming middle-burner role (PMID 17987447).
