Pine kidney

Broth pine buds act as expectorant due to the excitation of the secretory activity of the epithelium of the respiratory tract, reducing the viscosity of sputum, stimulating the function of ciliary epithelium. The viscosity of sputum depends on the release into the lumen of the respiratory tract glycoproteins synthesized by the glandular epithelium. In normal sputum, sialomucins are predominant, with which IgA is associated. The consistency of sputum also depends on the amount of bacterial antigens in it. The level of IgA in sputum is an objective indicator of the therapeutic effect of expectorant drugs. Under the influence of pine kidney decoction, the level of IgA increases, which is consistent with the improvement of clinical indicators. In addition, in the broth of pine buds are substances that disinfect sputum, providing antiviral and antimicrobial action. The pine buds also have a diuretic and choleretic property, like all plants containing essential oils.
