Chinese Waxgourd Seed
- Chinese
- 冬瓜仁
- Pinyin
- Dong Gua Ren
- Latin
- Semen Benincasae
Known in TCM as Dong Gua Ren (冬瓜仁), this sweet, slightly cold herb enters the Lung and Large Intestine. Traditionally, it clears the Lungs and transforms phlegm ... Dong Gua Ren is used for cough with phlegm-heat, thick sputum, and Lung constraint from retained Heat, most often applied for productive cough, abscess, and appendicitis. Modern research has identified Seed among its active constituents.

Traditional Use
Primary Actions
- Clears the Lungs and transforms phlegm ... Dong Gua Ren is used for cough with phlegm-heat, thick sputum, and Lung constraint from retained Heat.
- Expels pus and resolves abscess ... it is a classical helper for pulmonary abscess and intestinal abscess when Heat, phlegm, and pus have formed internally.
- Promotes urination and reduces edema ... beyond its abscess role, it is also used for damp obstruction with swelling or difficult urination.
Secondary Actions
- Dong Gua Ren is the seed counterpart to the already-live Dong Gua Pi peel page ... the seed is relatively more phlegm-clearing and abscess-oriented, while the peel is the gentler edema-focused food-medicine lane.
- Its mild sweet-cool profile makes it broader and less harsh than many pus-draining medicinals.
Classic Formulas
- Wei Jing Tang ... classic Lung-abscess formula pairing Dong Gua Ren with Lu Gen, Yi Yi Ren, and Tao Ren.
- Da Huang Mu Dan Tang ... intestinal-abscess tradition in which Dong Gua Ren helps clear Heat and expel pus.
- Yi Yi Fu Zi Bai Jiang San ... abdominal-abscess context where Dong Gua Ren may be added or paired with other pus-resolving herbs depending on the presentation.
Classical References
- TCM teaching describes Dong Gua Ren as sweet and slightly cold, entering the Lung and Large Intestine to transform phlegm, expel pus, and promote urination.
- Classical formula use makes clear that this is not simply a food seed ... it has a specific role in phlegm-Heat and internal abscess patterns.
Modern Research
Active Compounds
- Seed oils and fatty-acid fractions ... prominent chemical components in modern Benincasa seed analyses
- Quercetin, rutin, and related phenolics ... measurable seed constituents relevant to antioxidant interpretation
- Cucurbit-type and other broader Benincasa metabolites ... part of the plant-wide phytochemical profile
Studied Effects
- A 2023 GC-MS study analyzed bioactive compounds from Benincasa hispida seed extracts, supporting ongoing interest in the seed as a chemically active medicinal-food material rather than an inert byproduct (PMID 36685362).
- A 2016 analytical study quantified quercetin and rutin in Benincasa hispida seeds, helping define the phenolic profile of Dong Gua Ren (PMID 26941534).
- A 2021 plant-wide review of Benincasa hispida summarized anti-inflammatory, antioxidant, diuretic, and gastroprotective research, providing broader context for the traditional Lung, dampness, and abscess uses of the seed lane (PMID 34521541).

Safety & Interactions
Contraindications
- Cold-phlegm cough without Heat
- Marked Spleen and Stomach deficiency-cold
Cautions
- Dong Gua Ren is mild, but its cool nature can be a poor fit for weak digestion or cold, clear sputum patterns.
- Persistent abscess symptoms, bloody sputum, or severe abdominal pain need medical evaluation rather than prolonged self-treatment.
