Tulip (Yujin), detailed under the entry for Wenju Yujin.

Jianghuang (Curcuma Longa), old records do not state its place of origin; currently, it is abundant in Jiang, Guang, and Shuchuan regions. The leaves are green, approximately one to two chi long and three to four cun wide, with diagonal veins resembling those of a red banana leaf but smaller; the flowers are red and white, gradually withering by Mid-Autumn Festival, emerging only in late spring; the flowers appear first, followed by the leaves, and it does not bear fruit. The rhizome is coiled, yellow, similar to ginger but rounder, with nodes. Some say that true Jianghuang refers to old ginger planted for over three years, which can flower; the flowers grow near the root base, similar to lotus roots, with hard nodes, possessing a pungent aroma, found where ginger is cultivated. Roots are harvested in August, sliced, and dried in the sun. People in Shu use it to treat abdominal distension due to Qi stagnation and postpartum blood stasis attacking the heart, with remarkable efficacy. Barbarians eat it raw, claiming it can dispel evil influences and ward off malignancy. Upon examination, Yujin, Jianghuang, and Ezhu are similar substances. Su Gong failed to distinguish them carefully, treating them as one entity. Chen Cangqi resolved this dispute by stating: Ezhu is bitter in taste and green in color; Jianghuang is acrid in taste, warm in nature, and yellow in color; Yujin is bitter in taste, cold in nature, and red in color, primarily used to treat febrile diseases in horses. These three substances differ, and their applications are entirely distinct. Furthermore, Liu Yuanlin's commentary on the *Wu Du Fu* states: "Jianghui" is not a single type, describing it as large as a snail, with a strong odor approaching putrefaction; people in the southern lands pound it to make a relish, also known as Lianjiang (Cheap Ginger). It grows among sand and stones and belongs to the ginger family. Its flavor is highly acrid and fragrant; after peeling, it is pickled with black plums and salt juice to be ready for use. It is found in Shian. Based on this, Lianjiang is of the same category but constitutes a distinct item. In the capital region in recent years, ginger has been widely cultivated, and Jianghuang often appears for sale, which is actually old ginger; market vendors buy it and eat it raw, claiming it is most effective for treating Qi disorders. Physicians also frequently incorporate it into major prescriptions for treating Qi-related ailments.

Peng'ezhu (Curcuma Phaeocaulis), originally from Western Regions and various prefectures in Southern Guang, now also found in Jiangsu and Zhejiang. Seedlings emerge in March in fields. The stem is about the size of a coin and two chi high; the leaves are pale green-white, one to two chi long and up to five cun wide, somewhat resembling lotus leaves; in May, it produces yellow spike-like flowers with slightly purple tips; the rhizome resembles ginger, but the Ezhu tuber is located beneath the root, resembling chicken or duck eggs, varying in size. Harvested in September, the coarse skin is peeled off, steamed until cooked, and then dried. This substance is extremely hard and difficult to crush; when needed, it is roasted thoroughly in hot ashes, then pounded in a mortar while hot, breaking down into powder. It is not seen in ancient prescriptions. Currently, it is considered an essential herb for physicians treating accumulations and Qi stagnation; it is effectively used in combination with Jing Sanleng (Burreed Rhizome). It is also commonly used in gynecological formulas.
