[Jianghuang (Curcuma Longa Rhizome)]
Bitter, pungent, warm. Enters the blood aspect of the Foot-Taiyin Splein Meridian and the Foot-Jueyin Liver Meridian. Breaks blood stasis and moves qi downward. Dispels wind-heat and dissipates carbuncles and swellings; its potency is more vigorous than that of Yujin. Combined with Rougui (Cinnamon Twig), it treats unbearable heart pain and postpartum pain caused by blood masses. Pianzi Jianghuang excels at regulating qi within the blood. It treats wind-bi pain in the arms. The flat slices resembling dried ginger are called Pianzi Jianghuang. Contraindicated for patients with blood deficiency.
[Yujin (Curcuma Aromatica Rhizome)]
Pungent, bitter, cold. Enters the Hand-Shaoyin Heart Meridian and the Hand-Jueyin Pericardium Meridian. Cools the heart and disperses stagnation, breaks blood stasis and moves qi downward. Treats various pains in the chest and abdomen caused by blood and qi disorders, retrograde menstruation in women, hematemesis (vomiting blood) and epistaxis (nosebleed), postpartum敗血 (decayed blood) rushing to the heart, mental derangement such as mania, phlegm misting the heart orifices, chickenpox toxins entering the heart, and "Tiaosheng" gu poison. Combined with Gancao (Licorice Root), Zhu Xin Xue (Pig Heart Blood), and Bingpian (Borneol), it treats chickenpox toxins entering the heart. Combined with Mingfan (Alum), it treats phlegm-induced dementia. Paired with Congbai (Scallion White), it treats hematuria. Paired with Shengma (Cimicifugae Rhizoma), it treats "Tiaosheng" gu poison. (In Lingnan, there is a harm called "Tiaosheng" hidden in food/drink, where fish/meat can revive and grow inside the human abdomen; this herb resolves it.) Assisted by Lilu (Veratrum Nigrum Rhizome), it resolves wind-phlegm obstruction. Assisted by Huaihua (Sophorae Flos), it clears heat-toxins. Mixed with Jiuji Zhi (Leek Juice), Jiangji Zhi (Ginger Juice), and Tongbian (Child's Urine), it treats retrograde menstruation. Diluted with Zhuli (Bamboo Sap), it descends phlegm-fire. (When qi descends, fire also descends.) Use as a powder or grind for juice. Contraindicated for yin deficiency with flaming fire, qi deficiency with distension and stagnation, and hematemesis not related to qi stagnation.
[Peng'ezhu (Curcuma Phaeocaulis Rhizome)]
Pronounced "Shu", also known as "Yao".
Works well when combined with vinegar and wine.
Pungent, bitter, warm. Enters the qi aspect of the Foot-Jueyin Liver Meridian. Breaks blood stasis caused by qi stagnation. Effective for all conditions where qi and blood condense causing pain. Combined with Muxiang (Aucklandiae Radix), it treats cold qi attacking the heart. Combined with Awei (Asafetida), it treats infant intestinal colic/torsion (meaning the accumulation pathogen is broken).
This substance is extremely hard and difficult to crush; it must be wrapped in flour and roasted thoroughly, then crushed while hot. Stir-fried with vinegar or wine, it can guide the medicine into the blood aspect. Or used as a ground powder, it should be combined with Renshen (Ginseng Radix et Rhizoma) and Baizhu (Atractylodis Macrocephalae Rhizoma) to avoid damaging primordial qi.
For abdominal masses in patients, attacking them only breaks the knot, while tonifying may assist the pathogen. However, if the attacking method is improper, it causes primordial qi to decline daily, making the accumulation worse, leaving doctors helpless. In such cases, one should use external plasters to disperse qi and reduce accumulation, and internal decoctions to tonify qi and nourish yin, so that both attacking and tonifying achieve their effects. Thus, Ezhu should not be used lightly.
