Schisandra, also referred to as Schizandra or Schisandra chinensis, comes from a vine native to China and parts of Russia. Its berry is used as a form of traditional Chinese medicine.
The fruit is also known as the Five Flavor Berry because its taste captures the five major favors – sour, sweet, salty, bitter, and spicy .
In a pilot trial on 50 people with chronic hepatitis C, an oral combination of antioxidants including schisandra reduced viral load, ALT levels, and tissue damage in 25-44% of the patients and improved health assessment in 58% .
In mice with heart muscle inflammation caused by the coxsackievirus B3, a traditional Chinese medicine formula with schisandra (Qishaowuwei) increased survival, restored the CD4+ to CD8+ T cell balance, and reduced heart tissue damage and viral loads .
Compounds isolated from different schisandra species were active against the following viruses in test tubes:
In 60 pneumonia patients, a product containing rhodiola, schisandra, and Siberian ginseng (ADAPT-232) reduced the duration of antibiotic treatment and improved quality of life, compared to standard treatment alone .
In an antibacterial study, lignan-containing schisandra extract inhibited a microbe that causes pneumonia (Chlamydia pneumoniae) .
Lung Damage and Failure
In guinea pigs with cough and lung inflammation caused by cigarette smoke, schisandra extract and several of its compounds (including fruit polysaccharide 1) suppressed cough and reduced the production of pro-inflammatory molecules [21, 22].
In asthmatic mice, oral schisandra fruit syrup improved lung function and reduced the blood levels of 2 inflammatory mediators (nitric oxide and IL-6) .
