It selectively inhibits succinate dehydrogenase in the muscles of the worm, affects the anaerobic metabolism of the worm muscles, and reduces energy production; it depolarizes the nerve muscles, causing continuous muscle contraction and paralysis; its cholinergic effect is beneficial to the excretion of the worm; it may have an inhibitory effect on the microtubule structure of the worm; it has immune regulation and immune excitation functions.

By inhibiting cyclooxygenase, it selectively inhibits the synthesis of prostaglandins in the hypothalamic temperature regulation center, leading to peripheral vasodilation and sweating to achieve an antipyretic effect; by inhibiting the synthesis and release of prostaglandins, it increases the pain threshold and has an analgesic effect. It is a peripheral analgesic, weaker than aspirin, and is only effective for mild and moderate pain. This product has no obvious anti-inflammatory effect.

By inhibiting cyclooxygenase, it selectively inhibits the synthesis of prostaglandins in the hypothalamic temperature regulation center, leading to peripheral vasodilation and sweating to achieve the effect of antipyretic; by inhibiting the synthesis and release of prostaglandins, it increases the pain threshold and plays an analgesic role. It is a peripheral analgesic, with a stronger effect than acetaminophen, and is only effective for mild and moderate pain. This product has no obvious anti-inflammatory effect.

It helps to enhance the analgesic effect, but the specific mechanism is not clearly mentioned.

Participates in the formation of bones and the reconstruction of bone tissue after fracture, muscle contraction, nerve transmission, coagulation process and reduces the permeability of capillaries, etc.

1. Anti-inflammatory effect: (1) Anti-allergic effect. Glycyrrhizin has anti-allergic effects such as inhibiting local allergic necrosis reaction in rabbits and inhibiting Schwartzman phenomenon. For corticosteroids, it can enhance the hormone's inhibitory effect on stress response and antagonize the hormone's anti-granulation and thymic atrophy effect. It has no effect on the exudation of hormones. (2) Inhibitory effect on arachidonic acid metabolic enzymes. Glycyrrhizin can directly bind to phospholipase A2 and lipoxygenase, selectively inhibit the phosphorylation of these enzymes and inhibit their activation. 2. Immunomodulatory effect: Glycyrrhizin has the following immunomodulatory effects in in vitro tests: (1) Regulatory effect on T cell activation; (2) Inducing effect on gamma interferon; (3) Activating NK cells; (4) Promoting the differentiation of extrathymic T lymphocytes. 3. Inhibitory effect on experimental hepatocyte damage: Glycyrrhizin has the effect of inhibiting hepatocyte damage caused by carbon tetrachloride. 4. Inhibit virus proliferation and inactivate viruses: In the MHV infection experiment in mice, administration of glycyrrhizin can prolong their survival days; in the vaccinia virus pox prevention experiment in rabbits, it has an effect of preventing pox; in the in vitro experimental system, the proliferation of herpes viruses and the inactivation of viruses were also observed.
