Known in TCM as Tian Hua Fen (天花粉), this sweet and slightly bitter, cold herb enters the Lung and Stomach. Traditionally, it clears heat and generates fluids ... Tian Hua Fen is a classic root medicine for thirst, dry mouth, irritability, and fluid depletion caused by heat, most often applied for dry cough, productive cough, and abscess. Modern research has identified Trichosanthin among its active constituents.

Traditional Use
Primary Actions
- Clears heat and generates fluids ... Tian Hua Fen is a classic root medicine for thirst, dry mouth, irritability, and fluid depletion caused by heat.
- Clears Lung heat and moistens dryness ... it is used for dry cough, thick difficult sputum, and heat-dryness injuring the upper burner.
- Reduces swelling and expels pus ... traditional use includes abscess and deep toxic swelling patterns where heat and dryness combine.
Secondary Actions
- This page should stay on the broader Tian Hua Fen trade-root lane and remain distinct from the already-live `root-of-pedateleaf-snakegourd` species-forward sibling.
- The local prompt points to a general pharmacy root trade identity that can include more than one Trichosanthes source species, which is why the content stays broader than a single botanical entry.
Classic Formulas
- Tian Hua Fen San ... classic fluid-generating formula for wasting-thirst patterns with dryness and internal heat.
- Bei Mu Gua Lou San ... dry Lung cough formula where Tian Hua Fen moistens dryness and helps transform constrained phlegm.
- Xian Fang Huo Ming Yin and related abscess formulas ... the root is used when swelling, heat, and pus formation require cooling and dispersing.
Classical References
- Traditional herbology presents Tian Hua Fen as a cold sweet root that both clears heat and generates fluids, which explains its thirst and cough applications.
- Classical incompatibility tradition also places the Gua Lou and Tian Hua Fen group opposite Wu Tou-type aconite preparations.
Modern Research
Active Compounds
- Trichosanthin and related ribosome-inactivating proteins ... the best-known modern constituents of the root tuber
- Cucurbitacin-type bitter triterpenoids ... studied in anti-inflammatory and antitumor contexts
- Polysaccharide and protein fractions ... broader extract classes discussed in immune and tissue-response work
Studied Effects
- A 2025 review on Trichosanthis Radix summarized botany, ethnomedicine, phytochemistry, pharmacology, quality control, and toxicology and is the best modern overview for the broader Tian Hua Fen trade lane (PMID 40334818).
- A 2016 review of ribosome-inactivating proteins from Trichosanthes species highlighted the root tubers as major sources of bioactive proteins such as trichosanthin (PMID 27225069).
- A 2025 review revisited trichosanthin and its disease-related roles, confirming that much of modern interest in Tian Hua Fen still centers on this unusually potent root protein (PMID 40541793).

Safety & Interactions
Contraindications
- Pregnancy
- Cold from deficiency with loose stool
- Concurrent use with Wu Tou type aconite preparations in classical incompatibility traditions
Cautions
- Tian Hua Fen root proteins are pharmacologically active, so concentrated extracts should not be treated as interchangeable with casual cucurbit food use.
- Cold fluid-generating roots can worsen weak digestion if the underlying pattern is not heat-dryness.
