Disclosure of Invention
In order to solve the problems, the invention provides an oral product which not only can clean the oral cavity, but also can relieve gingivitis, stop bleeding, relieve swelling, relieve toothache, eliminate halitosis and oral ulcer, and basically has no adverse reaction.
The invention is realized by adopting the following technical scheme.
A composition for oral cavity comprises the following active components in parts by weight:
0.01-10 parts of purple bamboo salt;
0.01-15 parts of dragon's blood extract;
0.01-12 parts by weight of latanib extract.
Preferably, the composition for oral cavity comprises the following active components in parts by weight:
0.1-5 parts of purple bamboo salt;
0.1-5 parts of dragon's blood extract;
0.5-5 parts by weight of latanib extract.
Further research shows that in the composition for oral cavity, the active components comprise the purple bamboo salt, the dragon's blood extract and the latanib extract, the mass ratio of the purple bamboo salt to the dragon's blood extract to the latanib extract is 1 (1-5) to 0.5-7, and particularly, the synergistic effect is better when the mass ratio of the purple bamboo salt to the dragon's blood extract to the latanib extract is 1 (1.2-3) to (1-2.5).
In some embodiments of the present invention, in the composition for oral cavity, the mass ratio of the salt of black bamboo, the dragon's blood extract and the latanib extract is 1:5:7, 1:3:0.5, 1:2.5:2.5, 1:1.2:1, respectively.
The purple bamboo salt has a long history of preparation and application, and has the effects of resisting bacteria, diminishing inflammation, expelling toxin, beautifying and the like. The purple bamboo salt can be prepared by adopting the prior art or purchased in the market.
In some embodiments of the invention, the purple bamboo salt is prepared by filling salt into a bamboo tube, and calcining and extracting the salt for nine times at high temperature, and has better effects of resisting bacteria and diminishing inflammation, expelling toxin, beautifying and the like.
In some embodiments of the present invention, the purple bamboo salt is prepared as follows: filling salt into green bamboo tube, and sealing with clay. The bamboo tube is put into a furnace and calcined by pine at the high temperature of 1500 ℃ and 1000 ℃. The salt column after 8 hours of calcination was ground to a powder and calcined again and repeated 8 times. The column was placed in the oven at 9 th time and heated to above 1300 ℃ with a turpentine fire. Melting salt, pouring into a bowl, and cooling to obtain the final product.
Sanguis Draxonis (Draconis Sanguis) is resin exuded from fruit of Daemonorops draco Bl (Palmaceae), and is widely used as traditional and rare medicinal material worldwide. The dragon's blood has stronger antibacterial, anti-inflammatory and anti-tumor activities and the treatment effects of hemostasis, anti-thrombosis and the like. Dracorhodin is an important active ingredient of dragon's blood.
The dragon's blood extract is prepared by extracting and refining resin of daemonorops draco of Palmae and plants in the same genus. The dragon's blood has the reputation of the holy medicine for promoting blood circulation, has mild nature, sweet, warm, salty and mild taste, and is suitable for heart and liver meridians, and has the functions of promoting blood circulation, removing blood stasis, relieving pain, stopping bleeding, resisting bacteria, resisting tumors, enhancing immunity, reducing blood sugar, resisting inflammation, promoting epidermis repair and the like.
