Cangzhu Incense
Every year on Lunar New Year's Eve, people burn incense such as Cangzhu, as it is believed to expel plagues, eliminate dampness, and help raise yang energy. Cangzhu has a strong scent that can drive away dampness, evil spirits, and harmful energy; it is believed to dispel evil, eliminate pestilence, and cleanse stagnant or polluted air in abandoned places. It is especially effective for areas with dampness and negativity, as well as in houses that have been uninhabited for a long time. It is recommended for use during rituals, prayer, incense burning, purification, meditation, and emotional well-being.
Cangzhu Incense
From the "Compendium of Materia Medica," Zhang Zhongjing states: “It dispels all evil energy. When burned with red jujube and pig hoof, the smoke can purify the air. Tao Yinjv also says that it can eliminate bad energy and prevent disaster, which is why people burn Cangzhu during epidemics or at the turn of the year to ward off evil.”
Cangzhu was first listed in the "Shennong's Classic of Materia Medica" as a superior herb, without distinguishing between Cangzhu and Baizhu (White Atractylodes), which were both collectively called "Zhu."
From "Compendium of Materia Medica": Zhang Zhongjing mentions, "It dispels all evil energy. When burned with red jujube and pig hoof, the smoke purifies the air. Tao Yinjv also says it can eliminate bad energy and prevent disaster, so people burn Cangzhu during epidemics or at the turn of the year to ward off evil."
In "Compendium of Materia Medica - Zhengyi Edition," it is noted that Cangzhu has a strong, more potent fragrance than Baizhu. It can dry dampness, promote fluid circulation, and clear phlegm. Its aroma is particularly effective in eliminating impurities and bad air, especially in places with stagnant air or evil spirits. The strong, purifying qualities make it an essential remedy for epidemics.
Traditional Customs of the Han Chinese
This custom is popular across many regions of China. Every year on Lunar New Year's Eve, people burn Cangzhu and other incense as it is believed to expel plagues, eliminate dampness, and support the rise of yang energy.
During the Qing Dynasty, people burned Cangzhu along with pine branches, cypress leaves, and auspicious red powders, while lighting silver candles, staying awake through the night to usher in good fortune.
The Legend of Cangzhu
There is a story of a scholar who had just returned home after an exam in the capital and decided to visit West Lake on his way back. There, he met a charming woman, and after admiring her beauty, he offered to spend a large sum of money to travel back together. However, the woman declined his offer, and they parted ways.
Five years later, the scholar revisited the same place and, remembering the woman, felt regretful. Suddenly, he saw a figure resembling the woman and was overjoyed. He invited her to join him in touring the sights of West Lake, and they eventually stayed together at an inn.
After six months, the scholar again asked the woman to return with him. Sadly, the woman revealed that after he left, she had become gravely ill from missing him and had passed away. She had become a ghost. She warned him that since they had been together for so long, his body had absorbed the negative energy, and he would suffer from severe diarrhea upon returning home. She advised him to take a remedy known as "Pingwei Powder" to cure it.
The scholar, shocked and saddened, asked how such a mild medicine could help him. The woman explained that the Cangzhu in the remedy would remove the evil energy. When the scholar returned home, he indeed suffered from severe diarrhea but found relief after taking the remedy.
In ancient times, it was believed that wilderness miasma, epidemics, and evil energy were closely related to "dampness." These negative energies were thought to correspond to ghostly spirits, which is why such stories were passed down through generations.
