"Centuries-old pharmacy goes down in history,
Healing people with brilliant efficacy.
Yi Zheng plaster spreads across the four seas,
The famous city's old shop takes the top spot."
The Legend of "Ju Jing Liu Xiang"
In 1712, Chen Pengnian, the Governor of Water Transport, suffered from severe joint pain. After being cured by our paste, he was struck by its unique herbal aroma. Inspired by the ancient legend of the "Orange Well" saving people from plague, he gifted us the plaque.

Usage Indications
This precious historical packaging document details the traditional indications of Yi Zheng Gao: pain, bruising, injuries from falls, strain, bloating, stomach cold, swelling, numbness, and masses.
The inscription 'Available at pharmaceutical companies and pharmacies nationwide' bears witness to Yi Zheng Gao's widespread distribution and deep-rooted popularity across China.
The 200-Year War on Fakes
For over two centuries, our fame attracted countless imitators. In 1869 (Tongzhi Year 8), the 7th generation master Tang Mu petitioned six levels of government.
This stele, now a protected cultural relic, stands as the "First Anti-Counterfeiting Stele in China," a permanent guardian of our authenticity.
Tang Ruzhen
The Tang spirit extends beyond medicine. Tang Ruzhen, the 8th generation heir, was a person of extraordinary courage.
Inspired by Sun Yat-sen's call for women's rights, she donated over 50 mu (8+ acres) of her personal land to establish the Zhenjiang Women's Vocational School in 1927.
The Face That Guaranteed Quality
On the busy Wutiao Street, fakes were rampant. In 1922, the shop was officially registered as "Tang Lao Yi Zheng Zhai". But the ultimate seal of trust came in 1930.
This portrait guaranteed the authentic 80-herb formula. During the 1966 industrial consolidation, the formula was drastically cut.
Four-Tier Packaging · Imperial Tribute
During the 8th generation master Tang Zunlou's tenure, Yi Zheng Gao was packaged in four tiers:
- •Glass boxes with calligraphy by Jin Nong (one of the 'Eight Eccentrics of Yangzhou') reading 'Soothe Tendons, Invigorate Blood' and 'Prolong Life' — exclusively for the Imperial Palace;
- •Rosewood boxes for government officials;
- •Red cloth wrapping for general patients;
- •Blue cloth wrapping for charitable distribution.
1879
Our global journey isn't new; it began over 140 years ago. On February 16, 1879 (Guangxu Year 5), an advertisement in the Shen Bao (Shanghai News) announced our Shanghai branch.
Shen Bao, February 16, Guangxu Year 5 (1879)
"No goods leave the door if ingredients are missing;
Genuine goods at a fair price, no second price."
— Ancestral Motto
