Schizandra has been used historically by the Chinese to help suppress coughs and to protect against more serious repiratory conditions. In addition to having the soothing and calming effect on the respiratory system, it also has a calming effect on the nervous system. Schizandra also has been used historically to help increase the production of enzymes in the liver and the organs of digestion, especially the bowel. Schizandra has also been used as a kidney tonic and as a lung astringent. It is also great for coughs, night sweats, insomnia, thirst, and physical exhaustion. Many believe that Schizandra also has adaptogenic action, similar to that of ginseng, but with weaker effects.
