(Within the category of aromatic herbs) Ezhu (Rhizoma Curcumae) can drain blood stasis from the Qi level of the Liver meridian.
Ezhu specifically enters the Liver meridian. Its flavor is acrid and bitter, and its nature is warm. It has the powerful function of breaking up blood stasis at the Qi level of the Liver meridian.
Generally speaking, when a person's Qi and Blood are harmonious and peaceful, Qi and Blood flow together, and Blood adheres to Qi.
Once there is any deviation, either excessive Qi will obstruct Blood flow, or stagnant Blood will cause Qi stagnation.
Sanleng (Rhizoma Sparganii) has a bitter and neutral flavor; it can expel Qi stagnation within the Blood level of the Liver meridian. Ezhu has an acrid and warm flavor; it can further disperse Blood stasis within the Qi level. Therefore, for conditions such as unrelenting pain from accumulations, acid regurgitation, running piglet syndrome (Ben Tun), epigastric fullness (Pi), hidden masses (Pi), and fixed or movable masses (Zheng Jia) caused by Qi being obstructed by Blood, these two herbs must be used for treatment. (Note: "Zheng" refers to masses that are palpable upon pressure, resulting from food injury and taking shape from physical substances; "Jia" refers to masses resulting from blood injury, visible on the skin surface; "Pi" refers to fullness resulting from Qi injury; "Pi" [hidden] refers to masses resulting from accumulation, located in hidden areas and invisible. Among the Five Accumulations: Liver accumulation is called Fei Qi, located under the left hypochondrium, shaped like an inverted cup with head and feet, resembling a turtle or tortoise; Heart accumulation is called Fu Liang, starting above the umbilicus, thick as an arm, extending up to below the heart; Spleen accumulation is called Pi Qi, located in the epigastrium, covering an area large as a plate; Lung accumulation is called Xi Ben, located under the right hypochondrium, shaped like a large inverted cup; Kidney accumulation is called Ben Tun, originating in the lower abdomen and extending up to below the heart, resembling the running of a piglet, moving up or down without fixed timing. The Classics state: For large accumulations, toxic drugs may be employed. Stop when the pathogenic factor has been reduced by more than half; over-treatment leads to death. Therefore, to remove accumulations, one must nourish with sweet and warm tonics. It is also said: In robust individuals, if Qi flows freely, the accumulation resolves itself; in weak individuals, the pathogen lingers and causes disease. Zhang Jiegu stated: Robust people do not have accumulations; only deficient individuals do. Thus, by nurturing righteousness (healthy Qi), evil naturally eliminates.) This allows Qi to flow smoothly from Blood, preventing closure and obstruction.
However, although Pengzhu (Ezhu) belongs to the category of herbs that dissipate accumulations, (For Blood accumulation, suitable herbs include Tao Ren, Shan Jia, Gan Qi, Da Huang, Meng Chong, Pengzhu, Wa Leng Zi; for Phlegm accumulation, Ban Xia, Nan Xing, Bai Zhu, Zhi Shi, Meng Shi, Xiao Shi, Feng Hua Xiao, Bai Jie Zi, Hai Shi, Ge Fen; for Water accumulation, Da Ji, Gan Sui, Yao Hua, Yuan Hua; for Wine accumulation, Gan Ge, Shen Qu, Sha Ren, Dou Kou, Huang Lian, Gan Jiang, Gan Sui, Qian Niu; for Tea accumulation, Jiang Huang, Zhu Yu, Jiao Jiang; for Hidden mass accumulation, San Leng, Ezhu, Ba Shuang, Da Huang; for Meat accumulation, Shan Zha, A Wei, Xiao Shi; for Gu accumulation, Xiong Huang, Xi Hui, Bing Lang, Lei Wan, Wu Yi, Shi Jun Zi, He Shi; for Malaria accumulation, Tao Ren, Bie Jia, Cao Guo.) if taken by deficient individuals, it is most dangerous. It is best to combine it with tonics such as Ren Shen and Bai Zhu.
The larger variety is known as Guangzhu. (Song states: This material is extremely hard and difficult to crush.) It should be roasted thoroughly in ash fire and crushed while hot. Alternatively, it can be ground with vinegar or wine, or used after boiling.
