Problems solved by technology

The use of pure natural plant extracts to treat pruritus has few side effects and is fresh and natural for patients, but relatively high requirements for formulation developers
Because the therapeutic effect of pure natural plants is not as obvious and fast-acting as antibacterial agents and hormones, this requires the formulation research and development personnel to select a combination formula that is symptomatic and has good synergistic effect from the vast variety of plants, and the experience and formula that predecessors can provide are not as good as Western medicine
[0004] In addition, in the past, the treatment of pruritus only focused on the therapeutic effect of the preparation, but did not pay attention to the treatment duration of the preparation
Pruritus is a continuous and multiple process. If the maintenance time of the preparation is short, the patient needs to apply the preparation frequently, which brings great inconvenience to the life of the patient.

Abstract

The invention relates to gel compositions, in particular to an itching-relieving gel composition using pure natural plant extract as the raw material. The itching-relieving gel composition comprises, by weight, 0.1-2 parts of purslane extract, 0.1-2 parts of Anthemis nobilis L. extract, 0.1-2 parts of radix glycyrrhizae extract, 0.1-2 parts of Azadirachta indica extract, 0.5-4 parts of Carbomer, 0.12 part of polyethylene glycol-8, 0.85 part of PEG-40 hydrogenated castor oil, 5-15 parts of glycerin, 0.01-0.05 part of ethylparaben, 65.85-93.17 parts of purified water, and the like. The itching-relieving gel composition has the advantages that the itching-relieving gel composition can effectively relieve itching caused by skin allergy, eczema or mosquito bites; untoward side effects caused by the use of antibacterial agents, hormones and the like are avoided; the itching-relieving gel composition is easy to smear and use and capable of forming a layer of protecting film on the surface of the skin and has a partial release-control effect.

Description

technical field [0001] The invention relates to a gel composition, more specifically to a gel composition used for relieving itching and using pure natural plant extracts as raw materials. It belongs to the field of daily chemical products. Background technique [0002] Pruritus is one of clinically common skin diseases, which brings great inconvenience to people's life. What causes itchy skin? There are many reasons for itchy skin. Common causes can be attributed to skin inflammation, dryness, infection, or insect bites. The general treatment of this type of pruritus uses western medicine more. Western medicine often contains antibacterial agents (such as compound ketoconazole, lincomycin lidocaine, morpholine hydrochloride, etc.), and its side effects often include central obesity, hypokalemia, edema, nausea, vomiting, high blood pressure, acne, Hirsutism, sweating, loss of appetite, hypoglycemia, etc.; Western medicines often contain hormones (such as dexamethasone, k...
