Problems solved by technology

[0002] The active ingredients of camellia have excellent heat-clearing and hemostatic functions, and have been widely used in the treatment of diseases such as medicine and surgery. It is of positive significance to use the medicinal effects of active ingredients of camellia in the field of oral health care, while the traditional active ingredients of camellia The most common extraction method is water extraction or ethanol extraction and crystallization method. These two methods all need to be cooked at high temperature for a long time. Therefore, there are many impurities in the camellia extract extracted by the above-mentioned technology. The low problem is not conducive to th
