Cang Er Zi San

Cang Er Zi San from Treasure of the East is a classical Chinese herbal formula in concentrated 5:1 granules (100g bottle), also known as Xanthium Formula.

This foundational formula disperses wind, opens the nasal passages, relieves pain, and clears the head. In modern Western terms, it supports healthy sinus and nasal function, helps maintain normal inflammatory responses in the upper respiratory tract, promotes clear breathing and mucus drainage, and assists with comfort during congestion or irritation—making it particularly useful for patterns of wind invasion (wind-cold or wind-heat) attacking the head and nasal passages, such as nasal congestion or stuffiness, runny nose (clear or yellow), sneezing, sinus pressure or frontal/temporal headache, reduced sense of smell, post-nasal drip, or facial heaviness, commonly seen in acute or chronic rhinitis, sinusitis, allergic rhinitis, or common cold with prominent nasal symptoms in TCM terms.

Treasure of the East specializes in full-spectrum, water-based herbal extracts produced by Tianjiang Pharmaceutical, using premium, tested botanicals to preserve active compounds and energetic properties. Their products emphasize purity with no artificial additives.
