Traditional Chinese Medicine background and properties
Herb Description*
Liu Ji Nu is a Blood-moving herb uniquely named after an ancient Chinese emperor (Liu Yu, whose childhood name was Ji Nu). It is best known for treating injuries, wounds, and pain caused by stuck or stagnant Blood, including traumatic injuries, postpartum pain, and painful or absent menstrual periods. It also helps with indigestion and food-related abdominal pain.

Main Actions*
- Breaks Blood Stasis and Unblocks Menstruation
- Invigorates Blood and Alleviates Pain
- Stops bleeding and reduces swelling
- Resolves Food Stagnation and Transforms Accumulations
How These Actions Work*
'Breaks up Blood stasis and unblocks menstruation' means Liu Ji Nu has a strong ability to move and break through stagnant Blood. When Blood becomes stuck and stops flowing properly, it can cause severe pain, missed periods, or painful masses in the abdomen. This herb's warm, bitter nature drives it powerfully into the Blood level, dispersing clots and restoring flow. It is used for conditions like absent or painful periods caused by Blood stagnation, and postpartum abdominal pain from retained blood clots (lochia).
'Disperses stasis and alleviates pain' refers to this herb's ability to resolve bruising, swelling, and pain from physical trauma. Whether from falls, fractures, sprains, or battlefield injuries, Liu Ji Nu moves stagnant Blood away from the injured area, reducing swelling and relieving pain. It can be taken internally or applied topically as a powder for this purpose. Classical texts famously describe it as a "key medicine for metal-inflicted wounds" (金疮要药).
'Stops bleeding and reduces swelling' may seem contradictory for a Blood-moving herb, but Liu Ji Nu has the unique property of stopping bleeding precisely by breaking up stasis. As the classical text Ben Cao Qiu Zhen explains: when Blood is stuck, it cannot return to its channels, so bleeding continues. By breaking up the obstruction, the Blood can circulate normally again and the bleeding stops. Externally, the powdered herb is applied directly to wounds, cuts, or burns to stop bleeding and promote healing.
'Reduces food stagnation and transforms accumulations' reflects Liu Ji Nu's aromatic quality, which enlivens the Spleen and Stomach. When food sits undigested in the abdomen causing pain, bloating, or diarrhea, this herb can help move things through. This action is distinctive enough that the herb has earned the folk name "Hua Shi Dan" (化食丹), meaning "pill that dissolves food."
Patterns Addressed*
In TCM, symptoms cluster into recognizable patterns of disharmony that reveal what's out of balance in the body. Liu Ji Nu is traditionally associated with these specific patterns.
The following describes this herb's classification within Traditional Chinese Medicine theory and is provided for educational purposes only.
Why Liu Ji Nu addresses this pattern
Liu Ji Nu directly addresses Blood Stasis through its warm, bitter nature. Bitter descends and drains, while warmth activates Blood circulation. Together these properties allow the herb to powerfully break through stagnant Blood. It enters the Heart channel (the Heart governs Blood) and the Spleen channel (the Spleen holds Blood), giving it a direct pathway to resolve Blood accumulation. This makes it particularly effective when Blood Stasis manifests as traumatic injury pain, postpartum retained lochia, or abdominal masses.
A practitioner would look for one or more of these signs
From Blood stasis blocking the uterine vessels
Sharp, fixed, stabbing menstrual pain
Fixed location, worse with pressure, from stagnant Blood
Dark purple bruises from traumatic injury
Why Liu Ji Nu addresses this pattern
Liu Ji Nu's aromatic quality allows it to 'awaken' the Spleen and Stomach, addressing food that has accumulated and stagnated in the digestive system. Its warm nature helps to activate the Spleen's transforming function, while its bitter taste promotes downward movement of stuck food. Through its Spleen channel entry, it directly reaches the organ responsible for digestion. This action is secondary to its Blood-moving properties but is clinically distinctive, earning the herb the nickname 'Hua Shi Dan' (化食丹, the food-dissolving pill).
A practitioner would look for one or more of these signs
Fullness and pain after eating from undigested food
Loose stools with undigested food
Abdominal distension from food accumulation
