Curcuma longa comes from Tang Materia Medica: Curcuma longa, whose leaves and roots are like turmeric, flowers spring from roots and come out with seedlings, and flowers rot in summer without children. The roots are yellow, blue and white, and the method of making them is the same as that of Yujin. Xirong people call it an elixir. Its taste is bitter and bitter, which is the same as that of turmeric, but different from peanut. "Compendium of Materia Medica": Ginger is a ginger that has been planted for more than three years.
Flowers can grow in the rhizosphere, just like the lotus. The roots are hard and spicy, and it is rare to grow ginger. There are also newcomers to Xifan, which are similar to Yujin and Yaoyao. As Su Jing attached, Yaoyao is not turmeric, and Su can't distinguish between two things. It also tastes bitter and warm, and it is dominated by bad breath, heartburn and blood gas accumulation. Su Yun, Curcuma longa, and Yun Yujin are cigarette butts. If the husband is like this, there is no difference between the three things, and they are connected by their names, which is always called the sputum, and the work is different.
Today's taste is bitter and green; Turmeric is pungent, warm, non-toxic, yellow in color, and it is warm and not cold. Yujin tastes bitter and cold, is red in color, and is mainly caused by horse fever. The three things are different, and they are used separately. "Materia Medica": Turmeric, which can produce flowers, flowers in the rhizosphere, just like the lotus. I would like to make a case of Yujin, Curcuma longa and Yaoyao, which are similar, but Su Gong did not distinguish them in detail, saying that they are the same thing.
In recent years, many kinds of ginger have been planted, and ginger is often sold raw, but it is old ginger. People in the city buy it raw, and the cloud is the most important. Doctors are generous in treating qi and use it sometimes. Materia Medica:? Turmeric and turmeric are actually different. Yujin tastes bitter and cold, with red color and a cicada-like belly. Turmeric tastes pungent and yellow, and it is as big as a ginger melon. Compendium: Curcuma longa, which is flat like dried ginger, is the film turmeric recently, and the round one is cicada's belly turmeric, which can be soaked in water and dyed. Although it looks like turmeric, its face is not yellow.
