Zinc is an important component of many enzymes in the body and has the functions of promoting growth and development, improving taste, etc.

This product is a potassium sodium salt of dehydrated andrographolide succinate half ester made by esterification, dehydration and salt formation of andrographolide, an extract of the plant Andrographis paniculata. It is the same substance as the active metabolite of Andrographolide in the body. It has antipyretic, anti-inflammatory and sedative effects, can promote the disappearance of fever, counteract the increased permeability of capillary walls, enhance the effect of sodium pentobarbital to induce sleep in mice, promote the function of the adrenal cortex of rats, and increase the body's emergency response to pathogen infection; it has a certain inactivation effect on influenza virus type AⅠ, type AⅢ, pneumonia adenovirus (Adv) type Ⅲ, type Ⅳ, and enterosyncytial virus (Rsv) in vitro.

This product has a strong antipyretic effect on rabbits with fever caused by bacterial endotoxins and can promote the disappearance of fever; it can counteract the increased permeability of capillary walls caused by xylene or histamine; it has a significant sedative effect; it can significantly promote the adrenal cortex function of rats and increase the body's emergency response to pathogen infection; it has a certain inactivation effect on influenza virus type AⅠ, type AⅢ, pneumonia adenovirus (Adv) type III, type IV, and enterosyncytial virus (Rsv) in vitro.

It antagonizes histamine and acetylcholine, relieves bronchospasm and has an anti-asthmatic effect; it has a strong inhibitory effect on the cough center; it causes increased secretions, thins thick sputum, reduces sputum viscosity, and makes it easier to cough up; it has a similar effect to aminophylline in relaxing bronchial smooth muscles; it increases the electrical stimulation threshold of the cerebral cortex, inhibits synaptic conduction of electrical stimulation and the spread of epileptic electricity.
