Siberian Cocklebur Fruit

Traditional Use

Primary Actions

• Disperses wind-cold and opens the nasal passages - Cang Er Zi is one of the classic herbs for chronic nasal obstruction, turbid discharge, and loss of smell.
• Relieves frontal headache and sinus pressure - it is especially associated with forehead and nasal-root pain when the nose is blocked.
• Dispels wind-damp and alleviates pain - beyond nasal use, it is sometimes added for joint pain and stiffness aggravated by cold and damp.
• Addresses wind-related itching - topical or internal use appears in traditional practice for pruritus and certain wind-dominant skin eruptions.

Secondary Actions

• Cang Er Zi is far more dangerous in the raw form; proper stir-baking and thorn removal before internal use are a traditional safety requirement, not a minor preference.
• Its nasal-opening specialty explains why it is repeatedly paired with Xin Yi and Bai Zhi rather than used alone for sinus patterns.

Classic Formulas

• Cang Er Zi San - classic nasal-obstruction formula pairing Cang Er Zi with Xin Yi, Bai Zhi, and Bo He for sinus congestion, turbid discharge, and frontal headache.
• Wind-damp pain formulas pair Cang Er Zi with herbs such as Qin Jiao or Du Huo when joint pain accompanies an exterior wind-damp presentation.
• Itching formulas may use processed Cang Er Zi internally or externally with other wind-dispelling herbs when pruritus or urticaria are dominant.

Classical References

• Shen Nong Ben Cao Jing and later herbology traditions treat Cang Er Zi as a wind herb that became especially famous for opening the nose.
• Traditional processing instructions consistently require roasting and de-thorning before internal use because toxicity is a core part of the herb's identity.
