The classical Chinese medicine described Schisandra as a high-grade herbal drug useful for a wide variety of medical conditions, especially as a kidney tonic and lung astringent. It is also widely known as a non-irritating aphrodisiac, regarded to increase stamina in males and excitability in females. Chinese herbalists use Schisandra as a kidney tonic, for coughs, night sweats, insomnia, thirst, and physical exhaustion. It is also regarded useful to improve work performance, build strength, and help to reduce fatigue.
