INGREDIENT SPOTLIGHT

Winter Melon/Dōng Guā 冬瓜

Benincasa hispida — the cooling, dampness-draining melon,
grown across East Asia as both vegetable and medicine for over 1,000 years.

FORMULA ROLE

Why LunarSip uses it.

Winter melon gives LunarSip’s Winter Melon Lotus Leaf Tea its cooling, fluid-balance direction. It pairs naturally with lotus leaf because both ingredients are traditionally connected with lightness after meals and a less heavy daily routine. In this 8-herb formula, winter melon supports the blend’s gentle character while lotus leaf, cassia seed, tangerine peel, hawthorn, oolong tea, red date, and rose round out taste and post-meal comfort.

HOW IT'S USED

The wax-skinned gourd.

In Chinese herbal practices, three parts of winter melon are traditionally distinguished: the flesh (Dōng Guā), the peel (Dōng Guā Pí, 冬瓜皮), and the seeds (Dōng Guā Zǐ, 冬瓜子). The peel — used by LunarSip — is the most diuretic part, traditionally classified as cooling and sweet, draining dampness while clearing heat. It is one of the most-used herbs in TCM formulas for damp-heat patterns and fluid retention.

In Western herbal traditions, Benincasa hispida has been studied for its polyphenols, triterpenes, and phytosterols. Modern pharmacology has documented diuretic, antioxidant, antihyperglycemic, anti-inflammatory, and gastroprotective activities — primarily in preclinical models. The dried peel preserves the bioactive compounds while the cucurbitin-rich flesh contributes most of the hydration value when fresh.

THE EVIDENCE

What the research says.

Modern research on winter melon spansdiuretic activity, metabolic wellness, and gastroprotection— primarily in preclinical and animal models.
