Herb Name: Yu Zhu. 玉竹 (yù zhú )
(also called Solomon’s Seal Rhizome, Polygonatum Root, or Polygonatum Odoratum as the botanical name )
Description:
- Yu zhu is the dried edible rhizome of a Solomon’s Seal flowering plant that belongs to the lily family.
- The plant is commonly grown in shaded gardens around the world for its pretty arching stems and hanging white flowers. In nature, the plant grows in the woodlands of China, the Himalayas, Siberia, and Europe.
- Harvested in autumn, the rhizome is sun dried and sliced for later use.
- Yu zhu has a light sweet taste, and are naturally yellowish white in color.
- In China, yu zhu typically comes from provinces like Hebei, Heilongjiang, Henan, Jiangsu, Shandong, and the inner regions of Mongolia.
- In Korea, this plant is used as a tisane (herbal tea) called dungulle.
Yu Zhu Benefits and Uses:
- Yu zhu is used in Chinese herbal soups to relieve dry throat or dry heaty coughs with scanty sticky phelgm due to yin deficiency in the lung.
- According to traditional Chinese medicine, yu zhu is mildly cooling and nourishes the yin in the lung and stomach. The herb is also known to moisten dryness in the lungs and strengthen the stomach.
- Yu zhu is commonly used with lady bell root for synergistic effects.
Preparation:

Where to Buy Yu Zhu:
- Yu zhu can be found in Chinese herbal stores.

I love yu zhu, and it’s interesting to read about it’s properties.
Great post!
My throat has been so dry lately and no amount of tea is making it better. I’m going to look for this the next time I’m at the Asian market! Do you think if I made a big batch of tea/soup with it, it would last in the fridge for a while so I could reheat it when I want to drink some?
Hi Ohkeeka, thank you for your visit and comment! I usually make soups with yu zhu, enough to last me about 3 days and I might drink 1 or 2 bowls per day. Definitely keep unfinished soup in the fridge so it doesn’t spoil. Be sure to use clay or stoneware to cook and store the soup whenever using herbal ingredients like this one. Metal reacts with some herbs and you want to avoid that. Pls also be sure to talk to a licensed herbologist or physicians too, especially if u’re taking medications. Hope your throat improves! =)
I really love how much I learn every time I visit your blog. This is another one that’s new one to me. There is a wonderful Chinese store not too far from me that I bet would have a lot of these wonderful ingredients. I’ll have to make a list and look for a few of them next time I’m there!
My throat is always so dry in the winter months. I’m going to check Asian market for yu zhu and try it in a soup as you suggested. Thanks!
