Abstract

The invention belongs to the field of Chinese medicine and particularly provides a composition for treating juvenile herpangina. The composition is prepared from, by weight, 40-50 parts of callicarpanudiflora general flavone, 10-20 parts of callicarpa nudiflora general phenolic acid, 20-30 parts of callicarpa nudiflora general phenylethanoid glycosides and 2-6 parts of callicarpa nudiflora polysaccharide. The invention also discloses application of the composition. The four components are all extracted from callicarpa nudiflora, are definite and cooperate with one another to take an effect, and the composition has a great effect of treating and / or preventing juvenile herpangina.

Description

technical field [0001] The present invention relates to an extract composition of Auranthus nudiflora and its application, in particular to an extract composition of Auranthus nudiflora with the effect of treating herpetic angina in children and an application thereof. Background technique [0002] Herpetic angina is an acute contagious pharyngitis characterized by acute fever and herpetic ulcers in the isthmus caused by enteroviruses. The main transmission route is feces-oral or respiratory. It is highly contagious and spreads quickly throughout the All over the world, it is sporadic or prevalent, and summer and autumn are the high incidence seasons, mainly affecting children aged 1 to 7 years old. [0003] The main clinical manifestations are fever, sore throat, pharyngeal isthmus mucosa small herpes and superficial ulcers. Patients with herpetic pharyngitis and recessive infection are the main source of infection of this disease. It can be transmitted directly through t...
