Abstract

The invention provides a plant extracting solution for relieving eczema, which is prepared from the following components in percentage by mass: 0.8 to 1.2 percent of kudzu vine extract, 1.0 to 2.0 percent of achillea millefolium extract and 0.8 to 1.2 percent of citron extract. The preparation method comprises the following steps: (1) preparing medicinal material Glycyrrhiza glycosides decoction pieces, crushing and sieving the decoction pieces, adding an alcohol-water solution, extracting the decoction pieces, and filtering and centrifuging the extract to obtain a Glycyrrhiza glycosides extracting solution; (2) adding medium-temperature alpha-amylase into the kudzu vine extracting solution, filtering the solution after enzymolysis, and collecting filtrate; (3) adjusting the pH value of the filtrate obtained in the step (2) to be alkaline; and (4) respectively preparing achillea millefolium and citron, crushing and sieving the medicines, adding the medicines into the liquid obtained in the step (3), performing extraction and filtration, adjusting the pH value of the filtrate to be acidic, stirring at room temperature, adding activated carbon, stirring the liquid, performing standing treatment at room temperature, centrifuging the mixture, and collecting supernate, thereby obtaining the plant extracting solution for relieving eczema. The eczema relieving effect of the prepared plant extracting solution is obviously better than that of a conventional extracting method.

Description

technical field [0001] The invention relates to the technical field of baby care products, in particular to a plant extract for alleviating eczema, its preparation method and application. Background technique [0002] With the rapid growth of the maternal and child industry, the sales of infant and child care products have also increased. According to data from Euromonitor International, baby and child care is one of the fastest-growing categories in the daily chemical industry, with a CAGR of 13.3% from 2015 to 2018. Among the common skin problems in infants and children, eczema is the most common skin problem. Infant eczema belongs to allergic skin inflammation, which is easy to recur, and the cause is often difficult to determine. Hormone drugs are commonly used in clinical treatment, and long-term use will have obvious side effects. The ingredients of existing plant-derived eczema relief products are safe and non-toxic, but their efficacy is generally not satisfactory...
