Description
Technical Field
The invention belongs to the field of daily chemicals, and particularly relates to a lithospermum nursing paste and a preparation method thereof.
Background
Radix Arnebiae is a Chinese medicinal material with sweet and cold nature and taste, has effects of promoting blood circulation for removing blood stasis, removing toxic substance, promoting eruption and cooling blood, and can be used for treating eczema, scald due to hot water and fire, and blood heat and toxic materials. Radix Arnebiae is often combined with Chinese medicinal materials such as radix Angelicae sinensis, radix Angelicae Dahuricae, and Borneolum Syntheticum to regulate immunity, promote blood circulation, enrich blood, clear away heat and toxic materials, relieve swelling and pain, and inhibit bacteria.
At present, the chemical components, pharmacological action and extraction process in the lithospermum are researched comprehensively and deeply in China, wherein the main components of the lithospermum are various naphthoquinone compounds such as shikonin, isobutyryl shikonin, acetylshikonin and the like, the wide pharmacological action is realized, in addition, the naphthoquinone compounds are extremely unstable, the temperature influence is large, and the stability of the naphthoquinone compounds can be damaged by high temperature. Therefore, an efficient method for extracting alkannin is of great importance.
The Chinese pharmacopoeia describes that the quality of three types of lithospermum is the best, namely Sinkiang lithospermum (soft lithospermum), lithospermum and lithospermum root. The lithospermum has the effects of resisting inflammation, inhibiting bacteria and the like, has obvious inhibiting effect on staphylococcus aureus, pseudomonas aeruginosa and the like, can promote the growth of cells on the surface of skin and accelerate wound healing, has stronger antioxidant activity, and can effectively remove free radicals.
CN109481725A discloses a ready-to-use compound lithospermum oil dressing and a preparation method thereof. The preparation method comprises the steps of mixing and sealing the lithospermum, the polygonum cuspidatum, the borneol, the vitamin E oil, the inositol hexaphosphate and the olive oil, then placing the sealed container in a vacuum constant temperature box, turning the sealed container every other hour to ensure that the medicines are fully and uniformly mixed, then cooling the sealed container to room temperature, filtering to remove impurities, adding the vitamin E oil and the inositol hexaphosphate to be uniformly mixed, filtering and sterilizing to obtain medicine leaching oil, soaking the medicine leaching oil into a single-layer polyester fiber net under the aseptic condition, and placing the medicine leaching oil into a sterile aluminum foil bag. Animal experiment research and clinical experiment research are respectively carried out, and experimental test results show that the shikonin oil gauze can obviously improve the healing speed of burn wounds, and can reduce the incidence rate and the generation area of scars aiming at healing wounds with scars of II-III degrees, but the preparation method has complex process and strict environmental requirements.
CN109432337A discloses a arnebia oil with skin care, traumatic injury stopping effects and its preparation method, wherein arnebia oil comprises arnebia, saffron, buffalo horn, frankincense, angelica, glabrous greenbrier rhizome, dahurian angelica root, cicada slough, myrrh, borneol, dendrobium, cortex lycii radicis, hispid fig and vegetable oil. The preparation method comprises soaking Olibanum, radix Angelicae sinensis, rhizoma Smilacis Glabrae, radix Angelicae Dahuricae, periostracum Cicadae and Myrrha in Chinese liquor, taking out the residues, adding into boiling vegetable oil A to obtain medicinal oil A, adding radix Arnebiae, stigma croci Sativi and cornu Bubali into the medicinal oil A, decocting for 6-10h, cooling, adding Borneolum Syntheticum, herba Dendrobii, cortex Lycii and Ficus Simplicissima, heating and stirring again, cooling to normal temperature, standing, and filtering to obtain radix Arnebiae oil. Clinical effect experiments for treating patients with poisonous insect bites show that the cure rate can reach 90 percent at most, the cure rate can reach 76 percent for patients with traumatic injuries and joint swelling and pain, and the lithospermum oil can treat diseases such as burns and scalds, necrosis removal and granulation promotion, lumbar muscle strain and the like, but the preparation raw materials have higher cost and the preparation condition has high requirements.
CN109700720A discloses an infant care cream and a preparation method thereof. The infant care cream mainly comprises propylene glycol, xanthan gum, allantoin, fatty alcohol, glyceryl stearate/PFG 100-stearate, phytosterol ester, medical vaseline, vitamin E acetate, polydimethylsiloxane, ammonium acryloyldimethyl taurate/vinyl pyrrolidone copolymer, alkanna tinctoria root extract, menthol, borneol, nicotinamide and the like. The preparation method comprises heating propylene glycol, xanthan gum and medical vaseline in water phase pot, heating span 60, Tween 60 and fatty alcohol in oil phase pot, mixing the obtained products, cooling to 40 deg.C, adding the rest materials, mixing, stirring, and sieving to obtain the final product. Experiments are carried out on infants (less than 2 years old) with eczema, the cure rate reaches 96% at most, the loss rate of the menthol after the infants are stored for 1 month reaches 7%, the preparation steps are complicated, the infants cannot be stored for a long time, and the failure rate is high.
In order to research the lithospermum erythrorhizon nursing ointment which is mild and non-irritant to skin, research personnel carry out a large amount of research, and the existing lithospermum erythrorhizon ointment also has the defects of complex preparation method, short storage period, irritation to skin and the like, so that the lithospermum erythrorhizon ointment which is mild and non-irritant to skin, and capable of sterilizing and diminishing inflammation and the preparation method thereof are urgently needed to be provided.
