Its effect is stronger than that of Curcuma (Yujin).

2. According to the *Compendium of Materia Medica*: “It helps with occasional discomfort in the arms associated with wind-dampness. The three substances—Jianghuang (Curcuma longa), Yujin (Curcuma wenyujin), and Ezhu (Curcuma phaeocaulis, zedoary)—have similar appearances and functions. However, Yujin acts on the Heart and supports healthy blood circulation, while Jianghuang also acts on the Spleen and supports the smooth flow of Qi. Ezhu acts on the Liver and additionally supports the blood aspect within the Qi, which is the difference.”

1. Transverse section: Epidermal cells flattened, with thin walls. Cortex broad, containing leaf trace vascular bundles; near the outer epidermis there are 6-8 rows of cork cells, flattened; Casparian strips of endodermal cells distinct. Pericycle consists of 1-2 rows of parenchyma cells; vascular bundles are collateral, scattered, with more bundles near the pericycle and gradually decreasing inward. Parenchyma cells contain oil droplets, starch grains, and reddish-brown pigment.

2. Take 0.2 g of the sample powder, add 20 ml of anhydrous ethanol, shake, allow to stand for 30 minutes, then filter. Evaporate the filtrate to dryness, and dissolve the residue in 2 ml of anhydrous ethanol to prepare the test solution. Separately, take 0.2 g of Curcumae Longae Rhizoma (Jianghuang) reference herb, and prepare a reference herb solution by the same method. Also, take curcumin reference substance and prepare a solution in anhydrous ethanol at a concentration of 0.5 mg per 1 ml as the reference substance solution. Perform the test according to the thin-layer chromatography method (General Rule 0502). Apply 4 μl each of the above three solutions separately to the same silica gel G thin-layer plate. Use a mixture of trichloromethane, methanol, and formic acid (96:4:0.7) as the developing solvent. After development, remove the plate, allow it to dry, and examine under daylight and ultraviolet light (365 nm). In the chromatogram of the test solution, spots of the same color or fluorescence spots shall appear at positions corresponding to those in the chromatograms of the reference herb solution and the reference substance solution.

Continuous cropping should be avoided, and it is often intercropped with tall-stemmed crops.

Propagation method

Propagation by rhizomes.

Cultivation Techniques

1. Rhizome propagation: At harvest time, select rhizomes free from pests, wellness, and damage as planting material. Store the seed rhizomes indoors in a dry, well-ventilated area, stacked for overwintering, and remove them in spring for planting. Before planting, cut large rhizomes longitudinally into halves or small pieces, each with at least 2 buds. To helps maintain rot in the seed rhizomes, allow the cut surfaces to dry slightly before planting, or dip them in lime or plant ash immediately after cutting and then plant promptly. Use bed planting with row spacing of 33–40 cm and hill spacing of 27–33 cm. Plant 3–5 pieces of rhizome per hill with buds facing upward, cover with soil, and lightly firm. The seed quantity per hectare is 2250–3000 kg.

2. Field management: After the seedlings have emerged, timely intertillage and weeding should be carried out 3-4 times per year. Combine this with top dressing, primarily using ammonia-based fertilizers such as human urine or ammonium sulfate. In September, heavily apply phosphorus and potassium fertilizers to promote tuberous root growth. During drought, especially in the period of tuberous root formation and enlargement, pay attention to irrigation. When there is excessive water or standing water around the area, it must be drained promptly to helps maintain root rot.

Pest and wellness control

1. wellness includes black spot, which harms leaves. At the early stage of onset, promptly remove diseased leaves and spray with 50% thiophanate-methyl or 65% zineb wettable powder at a dilution of 400–800 times.

2. Pests include cutworms and white grubs, which bite the fibrous roots during the seedling stage, helps maintain the formation of root tubers. They can be caught manually or lured with poison bait. There are also pests such as the ginger skipper butterfly and corn borer that cause damage.
