Toxicity and Biosafety — Schisandra chinensis

According to preclinical studies, aqueous and alcohol extracts of Schisandra chinensis fruits are characterized by low acute toxicity. In an experiment on mice with oral administration of the aqueous fruit extract, the LD₅₀ value exceeded 10,000 mg/kg of body weight, which corresponds to the category of low-toxicity substances according to WHO classification. With intragastric administration of the alcohol extract to rats, the LD₅₀ was more than 5,000 mg/kg of body weight. In chronic toxicity studies with prolonged oral administration for 90 days, no irreversible morphological changes in the liver, kidneys, and myocardium were detected at dosages many times exceeding therapeutic ones. Reversible changes in the activity of liver enzymes were noted with the use of high doses of concentrated extracts.

Genotoxicity and mutagenicity studies, including the Ames test and micronucleus test, did not reveal the mutagenic potential of standard fruit extracts. In cell culture models, no pronounced cytotoxicity was registered in the concentration range corresponding to pharmacologically active levels.

In general, Schisandra chinensis belongs to the category of low-toxicity plant preparations when following therapeutic dosages. An increase in blood pressure and stimulation of the central nervous system are considered pharmacologically conditioned effects, not toxic action.

Pharmacodynamics — Schisandra chinensis

The pharmacodynamic action of Schisandra chinensis is due to a complex of lignans, phenolic compounds, and essential components that exert a multi-level systemic effect on the nervous, endocrine, immune, and hepatobiliary systems. The adaptogenic effect is realized through modulation of the hypothalamic-pituitary-adrenal axis, which is accompanied by normalization of stress-induced changes in the cortisol response and an increase in the nonspecific resistance of the body to physical and psycho-emotional stress.

At the level of the central nervous system, an increase in the functional activity of the cerebral cortex, an enhancement of excitation processes without subsequent exhaustion, an improvement in synaptic transmission, and an increase in the resistance of neurons to hypoxic damage are observed. The neuroprotective effect is associated with antioxidant activity and stabilization of mitochondrial membranes, which contributes to a decrease in lipid peroxidation and preservation of neuronal energy metabolism.

The hepatoprotective effect is realized through the induction of detoxification enzyme systems, increased glutathione synthesis, stabilization of hepatocyte membranes, and a decrease in the severity of oxidative stress. A modulating effect on the activity of liver cytochrome enzymes is noted, which contributes to the normalization of metabolic processes and enhancement of the regenerative potential of liver tissue.

The immunomodulatory effect is manifested in the regulation of the activity of macrophages, natural killers, and T-lymphocytes, as well as in a decrease in the production of pro-inflammatory cytokines while supporting the physiological immune response. Antioxidant properties contribute to a decrease in damage to cellular structures by free radicals and stabilization of the vascular endothelium.

The cardiometabolic effect is associated with an improvement in energy metabolism in the myocardium, an increase in tissue resistance to hypoxia, and moderate stimulation of cardiac activity. Normalization of lipid metabolism and a decrease in the severity of oxidative damage to lipoproteins are noted.

Thus, Schisandra chinensis is characterized by a systemic adaptogenic, neuroprotective, hepatoprotective, and antioxidant profile of action, realized through modulation of the stress response, antioxidant protection, and regulation of cellular signaling pathways.

Pharmacokinetics — Schisandra chinensis

The active components of Schisandra chinensis, represented mainly by lignans of dibenzocyclooctadiene structure, as well as phenolic compounds and essential fractions, are characterized by good absorption with the oral route of administration. Absorption occurs mainly in the small intestine, where lipophilic compounds pass through enterocytes by passive diffusion. Biotransformation partially begins in enterocytes with the participation of phase I enzyme systems.

After absorption, the compounds are distributed in tissues with pronounced tropism for the liver, central nervous system, and myocardium. The lipophilic nature of lignans contributes to their passage through the blood-brain barrier, which correlates with neuromodulatory effects. In blood plasma, the active components partially bind to proteins, which ensures a prolonged systemic effect.

Metabolism is carried out mainly in the liver with the participation of microsomal system enzymes. An effect on the activity of cytochrome system isoenzymes is noted, which can modify the metabolism of concomitant substances. More polar metabolites are formed, excreted with bile and urine. Some conjugated forms undergo enterohepatic circulation, which contributes to maintaining the therapeutic level during the day.

Excretion occurs through the kidneys and with bile; an insignificant part is excreted through the intestine. With topical application, absorption is limited by the epidermal barrier; however, lipophilic components are able to penetrate into the surface layers of the skin, exerting a local antioxidant and membrane-stabilizing effect.

When applied through mucous membranes, absorption occurs faster, partially bypassing primary hepatic metabolism, which determines a faster systemic response when using rectal and nasal forms. Accumulation in tissues when following therapeutic dosages is not cumulative in nature and is not accompanied by signs of organ toxicity.

Mechanisms of Action and Scientific Rationale — Schisandra chinensis

The pharmacological activity of Schisandra chinensis is due to a complex of lignans that influence the regulatory systems of cellular homeostasis. One of the key mechanisms is the modulation of transcription factors that regulate the expression of antioxidant enzymes. Under the influence of lignans, the nuclear factor associated with the antioxidant response is activated, which leads to an increase in the synthesis of superoxide dismutase, catalase, and glutathione peroxidase. This reduces the level of lipid peroxidation and stabilizes cell membranes.

Additionally, inhibition of pro-inflammatory signaling pathways associated with the activation of nuclear factor kappa B has been noted, which leads to a decrease in the production of pro-inflammatory cytokines and inflammatory mediators. In cellular models, suppression of the expression of enzymes of the cyclooxygenase and lipoxygenase cascades has been shown, which explains the anti-inflammatory potential of the taxon.

With regard to the central nervous system, modulation of dopaminergic and serotonergic receptor systems, as well as an effect on cholinergic transmission, has been revealed. This is accompanied by an increase in the resistance of neurons to hypoxic damage and a decrease in apoptosis through the regulation of mitochondrial signaling pathways.

The hepatoprotective mechanism is realized through the induction of detoxification phases and enhanced glutathione synthesis, as well as through stabilization of hepatocyte membranes. An effect on cytochrome enzyme systems has been shown, which contributes to accelerated biotransformation of xenobiotics and a decrease in their damaging effect.

Thus, Schisandra chinensis exerts a systemic regulatory effect through antioxidant, anti-inflammatory, neuromodulatory, and membrane-stabilizing mechanisms, realized at the level of cellular signaling cascades and enzyme systems.

Synergy — Schisandra chinensis

The pharmacological synergy of Schisandra chinensis is most fully studied in combination with other adaptogenic and hepatoprotective taxa. In combined use with True Ginseng (Panax ginseng), potentiation of the stress-protective and neuromodulatory action is observed due to the complementary effect on the hypothalamic-pituitary-adrenal axis and the regulation of neurotransmitter systems. Schisandra lignans enhance antioxidant protection, while ginseng ginsenosides modulate energy metabolism and the expression of heat shock proteins, which forms an additive adaptogenic effect.

In combination with Rhodiola rosea, a potentiating effect on antioxidant activity and cell resistance to hypoxic stress has been described. Phenolic compounds of rhodiola and schisandra lignans jointly activate cellular mechanisms of the antioxidant response, which is accompanied by a decrease in the production of reactive oxygen species and stabilization of mitochondrial function. The nature of the interaction is assessed as synergistic at the level of cellular metabolism.

In combination with Milk Thistle (Silybum marianum), an enhancement of the hepatoprotective effect has been noted. Silymarin and Schisandra chinensis lignans act at different stages of antioxidant protection and hepatocyte regeneration, including membrane stabilization and induction of glutathione synthesis. In experimental models, a decrease in lipid peroxidation markers was shown with combined use compared to the use of each component separately.

Reference: Liu G.T. (1989). Pharmacological actions and clinical use of fructus Schisandrae. Chinese Medical Journal, 102(10), 740–749 https://pubmed.ncbi.nlm.nih.go...

Synergy with Eleutherococcus senticosus has also been described, in which an additive effect on indicators of physical endurance and nonspecific resistance of the body is observed. Eleutherosides and lignans act on overlapping but not identical signaling cascades, which provides a modulating systemic effect without a pronounced exhausting effect.

Thus, Schisandra chinensis exhibits pharmacological synergy mainly with adaptogens and hepatoprotectors of plant origin, realizing a potentiating and modulating interaction at the level of antioxidant, neuroendocrine, and cellular regulatory mechanisms.

Geography of Use and Traditional Medicine — Schisandra chinensis

Schisandra chinensis traditionally grows and is used in the northeastern regions of China, on the territory of the Korean Peninsula, in Japan, and in the Russian Far East. In Chinese traditional medicine, the plant is known under the name "Wu Wei Zi," which translates as "five-flavor berry." Historical mentions are found in ancient pharmacopoeial treatises of the Han Dynasty period, where the fruits were described as a remedy supporting vital energy and resistance to unfavorable climatic conditions.

In the traditional Chinese medical system, schisandra was used in the form of decoctions, infusions, and powders, and was part of multicomponent formulas aimed at harmonizing the functions of internal organs. In Korean and Manchu ethnomedical practice, the berries were used by hunters and warriors to maintain endurance during long transitions.

On the territory of the Russian Far East, the Nanai and Udege peoples consumed dried fruits as food and as a means of maintaining vigor during physical exertion. In ethnocultural practices, schisandra was considered a plant of power, contributing to the preservation of internal balance and resistance to cold.

In addition to medical use, the berries were used as a component of ritual drinks and as a symbol of vital energy. In some regions, the plant was endowed with protective properties and was associated with cleansing the body and strengthening the spirit.
