Indications

Enriches yinDirects ministerial fire downward

Yin deficiency with vigorous fire: Liver and Kidney yin no longer restrains the ministerial fire, which floats upward and steams. Because the heat is a consequence of emptiness, it is nourished away rather than simply cleared.

Clinical Manifestations

Tidal fever and night sweats
Steaming-bone sensation with heat in the palms and soles
Cough, sometimes with blood-streaked sputum, from yin deficiency
Irritability and quick temper with a dry mouth
Aching weak lower back and knees
Nocturnal emission

TongueRed with scant coating

PulseThin and rapid, forceful at the chi position

Menopausal hot flushes Hyperthyroidism Chronic low-grade fever Night sweats Pulmonary tuberculosis (traditional use)

Common adjustments

Night sweats pronounced — add Di Gu Pi 地骨皮 and Mu Li 牡蛎
Blood-streaked sputum — add Mo Han Lian 墨旱莲 and Ou Jie 藕节
Marked steaming-bone heat — add Qing Hao 青蒿 and Bie Jia 鳖甲
Frequent seminal emission — add Jin Ying Zi 金樱子 and Qian Shi 芡实

Contraindications

Cold and cloying. Withhold from patients with a weak Spleen and Stomach, poor appetite or loose stools, and from fever that comes from excess heat or from qi deficiency rather than from empty yin — misapplied here it damages digestion without touching the fever. Gui Ban is an animal-derived material; check sourcing and local rules on protected species.

For licensed practitioners’ reference only — not a self-treatment guide.

Pregnancy

Not recommended in pregnancy — Gui Ban is traditionally withheld from pregnant patients, and the formula is cold and rich. Use during pregnancy only if a practitioner prescribes it.
