Sizhitang
Time-Honored BrandSizhitang · Henan · Founded
Sizhitang, a time-honored pharmaceutical brand from Henan, derives its name from the 'Four Knows' allusion of Yang Zhen, embodying integrity in medical practice. Specializing in traditional Chinese herbal preparations, it upholds a legacy of ethical healing and meticulous craftsmanship.
Brand Story
The name Sizhitang originates from the Eastern Han dynasty scholar Yang Zhen's famous saying, 'Heaven knows, spirits know, I know, and you know,' symbolizing self-discipline and integrity in medicine. Its history traces back to a folk pharmacy in Henan during the Ming and Qing dynasties, renowned for homemade plasters, pills, and powders. During the Qianlong reign (1736-1795), a physician surnamed Yang in Huaiqing Prefecture (present-day Jiaozuo), skilled in treating external ulcers, named his shop Sizhitang in admiration of Yang Zhen's moral integrity. He adhered to the motto: 'Know the medicine, know the healing, know the virtue, know the heart.' In the Republican era (1912-1949), descendants created 'Sizhitang Wanying Plaster' for injuries and swellings, which gained popularity across northern Henan and southern Hebei. After public-private partnership in 1956, the brand merged into local clinics, preserving its traditional techniques. Sizhitang is not just a pharmaceutical brand but a carrier of the Central Plains' cultural tradition of 'virtue guiding medicine,' echoing Yang Zhen's spirit and serving as a vivid footnote to Chinese medical ethics.

Its cultural essence is anchored in the 'Four Knows,' integrating medical ethics into the production process, reflecting the Central Plains tradition that 'medicine virtue is human virtue.'
