☯ TCM Properties
Clears Lung Heat; Moistens the intestines and unblocks the bowels; Disperses accumulations and resolves stasis; Expels pus and reduces abscesses; Generates fluids and stops thirst
Traditional Chinese Uses
Tian Gua Zi (muskmelon seed) is a cool, sweet herb used in Chinese medicine to clear Lung Heat, transform Phlegm, and moisten the Intestines. It addresses Lung Heat with cough, internal abscesses with purulent sputum, and constipation from intestinal dryness. Its cooling, moistening properties make it similar in action to other seed-based herbs from the cucurbit family, and it is used in formulas for both respiratory and digestive conditions requiring heat-clearing and moisture-restoring treatment.
Botanical Description
Cucumis melo L. (muskmelon) is an annual trailing or climbing vine in the Cucurbitaceae, native to Africa and southwestern Asia and widely cultivated across temperate and subtropical regions for its edible fruit. The stems are angular, soft-hairy, 1-3 m long, climbing by simple unbranched tendrils. Leaves are alternate, simple, palmately 5-lobed or angled, 8-15 cm wide, with cordate bases and rough hairy surfaces. Flowers are yellow, solitary, with five fused petals; staminate and pistillate flowers are borne separately on the same plant. The fruit is a large fleshy pepo, variable in shape, size, and surface (smooth, netted, or ribbed), enclosing a central cavity filled with numerous flattened, ovate to elliptic, ivory-white to pale yellow seeds 8-12 mm long, which constitute the medicinal Tian Gua Zi.
Active Constituents
Linoleic acid
Polyunsaturated (omega-6) fatty acidConcentration: Predominant fatty acid of the seed oil, roughly 55-61% of total fatty acids
The major essential fatty acid of melon seed oil, contributing to its lubricating, intestine-moistening action and to general lipid-lowering and anti-inflammatory dietary effects.
Oleic acid
Monounsaturated (omega-9) fatty acidConcentration: Second most abundant fatty acid, roughly 19-28% of total fatty acids
A monounsaturated fatty acid that stabilises the oil and supports its emollient, bowel-moistening properties.
Palmitic acid
Saturated fatty acidConcentration: Roughly 10-13% of total fatty acids
The principal saturated fatty acid of the seed, a normal component of the fixed oil.
gamma-Tocopherol
Tocopherol (vitamin E isomer)Concentration: Dominant tocopherol, typically 70-96% of total tocopherols in the seed oil
The main vitamin E form in melon seed oil, providing antioxidant protection to the polyunsaturated fatty acids and contributing dietary antioxidant value.
Seed storage proteins (globulins/albumins)
ProteinConcentration: Approximately 15-27% of the seed by weight depending on cultivar
The seed is protein-rich; these proteins underlie its nutritive value and traditional use as a nourishing food-herb.
Phytosterols
SterolConcentration: Minor unsaponifiable fraction of the seed oil
Plant sterols in the oil contribute mild cholesterol-modulating and anti-inflammatory dietary activity.

Preparation Methods
Decoction of crushed seeds
Parts: seed
The dried ripe seeds are lightly crushed and decocted (commonly 6-9 g) to clear lung heat, moisten the intestines, and support resolution of internal abscess/pus in combination formulas.
Ground seed powder
Parts: seed
Seeds may be dried and ground to a powder taken with warm water, used chiefly for its moistening, laxative action on dry constipation.
Clinical Studies
Anticancer Properties of Different Solvent Extracts of Cucumis melo L. Seeds and Whole Fruit and Their Metabolite Profiling Using HPLC and GC-MS
Solvent extracts of Cucumis melo seeds and fruit were profiled by HPLC and GC-MS and tested against cancer cell lines by MTT assay; the chloroform extract showed notable cytotoxic activity, providing preliminary in vitro support for bioactivity of melon-seed constituents.
