Bottle Gourd Peel Classic Formulas — Natural Herb Library

Primary Actions

Promotes urination and reduces edema - used for facial swelling, abdominal distention from water retention, scanty urine, and damp fluid accumulation that needs a gentle draining herb.
Drains Dampness and supports resolution of jaundice and urinary heat - extended to damp-heat jaundice, hot strangury, and hematuria in regional and folk practice.
Relieves mild fluid-related fullness and swelling through a light food-medicine approach - the dried peel is milder than harsher diuretics and is often used when daily-life retention patterns need steady, moderate support.

Hu Lu Ke with Fu Ling, Zhu Ling, and Ze Xie - a straightforward edema pairing strategy for swelling, oliguria, and generalized water retention.
Hu Lu Ke with Hua Shi, Mu Tong, and Che Qian Zi - used when damp-heat obstructs urination and produces burning, dribbling, or dark scanty urine.
Hu Lu Ke with Yin Chen, Zhi Zi, and Jin Qian Cao - regional combination pattern for damp-heat jaundice with yellowing, abdominal fullness, and poor fluid movement.

IMPORT NOTE: the source XLSX used the generic pinyin 'Hu Lu' while the Latin clearly specifies Pericarpium Lagenariae. This record standardizes the drug-part identity to Hu Lu Ke, the dried bottle gourd peel or shell.
TCMLY records Hu Lu Ke as sweet and relatively neutral, acting mainly through the Lung and Kidney channels, with traditional use for edema, difficult urination, jaundice, and hematuria.
Regional sources vary in whether they describe the peel, shell, or whole fruit and in how strongly they emphasize modern metabolic uses, but they consistently agree on the core water-draining and swelling-reducing function.
