Schisandra chinensis is a creeping vine with small red berries that is native to Northern China and the Russian Far East. It is considered one of the 50 fundamental herbs in traditional Chinese medicine. Schisandra chinensis fruit has been traditionally used as a stimulating and fortifying agent in cases of physical exhaustion, and to inhibit fatigue.

Anti-fatigue properties of Schisandra chinensis

Schisandra chinensis first gained recognition as an adaptogen in the official medicine of the USSR in the early 1960′s [1]. Large number of pharmacological and clinical studies from Russian scientist show that Schisandra chinensis is able to counteract the effect of fatigue, increase endurance, and improve the physical performance [1,2]. However, these studies were not controlled. One of the first controlled studies, evaluating Schisandra chinensis as a performance enhancer, were done on horses [2,3,4]. The performance of the race horses was improved after treatment with Schisandra chinensis [4].

Cao et al. [5] employed swimming endurance test to assess anti-fatigue activity in mice 30 min after Schisandra chinensis extract was administered. Swimming time of treatmed group increased significantly (p < 0.05) when compared with that of the control group. The combination of mixed extracts of Schisandra chinensis and Chaenomeles sinensis also seem to enhance exercise capacity by lowering lactate accumulation [6]. Researchers also speculated that this may at least in part be related to reduction of skeletal muscle injury [6].

Schisandra chinensis is also added to sport supplements as a cortisol suppressant. Studies evaluating this report minor effects. Panossian et al. [7] reported a decline in post-exercise cortisol compared to placebo. Same researchers treated animals with multiple doses of mixed adaptogens (Eleutherococcus senticosus, Schizandra chinensis, Rhodiola rosea, Bryonia alba and Panax ginseng) and reported unchanged cortisol levels, while placebo group had increased cortisol by 200 to 300% [8].

Other benefits of Schisandra chinensis

Some studies are even showing that active ingredients in Schisandra chinensis can stimulate liver regeneration, prevent liver injuries and inhibit hepatocarcinogenesis (carcinogensis in the liver) as well as lipid peroxidation in rodents [9,10]. Schisandra chinensis has also show anti-carcinogen properties [11]. Although promising, further scientific research is needed to better evaluate effects of Schisandra chinensis on cancer therapy.

Schisandra chinensis side effects and toxicity

Schisandra chinensis is usually known as medicinal plants with few side effects such as toxicity [6]. Acute toxicity studies revealed that no obvious symptom of toxicity or significant changes in general behaviour in mice [5].
