Used for centuries in China and beyond, this humble rhizome from the Cyperus rotundus plant is gaining attention for its potential in both ancient healing and modern science.
In this article, we’ll explore its benefits, risks, traditional uses, and what research says—plus practical tips to understand this herbal gem. Whether you’re curious about managing mood swings or soothing a bloated belly, here’s everything you need to know about Xiangfu, backed by tradition and evidence.
What Is Cyperi Rhizoma (Xiangfu)?
Xiangfu is the dried root of Cyperus rotundus L., a plant that thrives in warm climates like those in Shandong, Zhejiang, and Hunan, China1. In TCM, it’s a go-to for balancing liver qi—the energy tied to emotions and overall harmony. Picture it as a spindle-shaped root, about 2-3.5 cm long, with a brownish surface and a subtle, fragrant scent. Its taste? A mix of pungent, slightly bitter, and sweet, with a neutral nature that makes it versatile2.
- Where It Works: Liver, spleen, and triple energizer meridians (TCM energy pathways).
- How It’s Prepared: Harvested in autumn, cleaned of hairy roots, then boiled or steamed and dried.
Renowned TCM expert Li Shizhen called it the “general commander of qi diseases” and the “chief of women’s medicine,” highlighting its knack for tackling emotional and menstrual woes. But what does it actually do? Let’s break it down.
