A classical treatise on Chinese herbal medicine, Shen Nung Pen Tsao Ching, describes schisandra as a high-grade herbal drug useful for a wide variety of medical conditions—especially as a kidney tonic and lung astringent. In addition, other textbooks on Traditional Chinese Medicine note that schisandra is useful for coughs, night sweats, insomnia, thirst, and physical exhaustion.⁵ Adaptogenic herbs, like schisandra, have been used in Traditional Chinese Medicine to improve the ability of the body to respond to stress.
