2. Tea polyphenols, amino acids and vitamins are high in the tender leaves of camellia, which has good effects of lowering blood pressure, blood lipid and blood sugar, protecting liver and detoxicating, and protecting cardiovascular and cerebrovascular diseases.
3. The old leaves of camellia have high mineral content, and have the effects of reducing blood fat, cholesterol, blood sugar, protecting liver and detoxifying, and enhancing immunity.

Medicinal value
According to the China Center for Disease Control and Prevention Institute of Nutrition and Food Safety, Guangxi Zhuang Autonomous Region Center for Disease Control and Prevention, Guangxi Zhuang Autonomous Region Health Supervision and Inspection Center, Beijing Center for Disease Control and Prevention Institute of Nutrition and Food Safety, Guangxi Zhuang Autonomous Region Analysis and Testing Research Center, Guangxi College of Traditional Chinese Medicine, Guangxi Agricultural College Experimental Center and other authoritative institutions, tests show that:
Camellia is non-toxic, contains more than 400 kinds of nutrients, and has no toxic side effects. Rich in tea polysaccharides, tea polyphenols, total saponins, total flavonoids, tea pigments, caffeine, protein, vitamin B 1, B2, vitamin C, vitamin E, folic acid, fatty acids, B- carotene and other natural nutrients; Camellia contains dozens of amino acids such as theanine and threonine, as well as many natural organic trace elements such as germanium (Ge), selenium (Se), molybdenum (Mo), zinc (Zn) and vanadium (V), and major elements such as potassium (K), calcium (Ca) and magnesium (Mg) which are of great significance to human health. Its main functional components and functions are as follows:
1, tea polysaccharide: Camellia is rich in polysaccharide substances. Polysaccharide can effectively control postprandial blood sugar rise, improve glucose tolerance, improve lipid metabolism disorder, and has obvious hypoglycemic effect.
2, tea polyphenols: Camellia is rich in tea polyphenols. Tea polyphenols can scavenge free radicals and reduce the increase of blood sugar in DM, thus improving its glucose tolerance and stabilizing blood sugar.
3. Total saponin: The content of camellia saponin is 6300mg/kg, which has the functions of strengthening heart, relaxing blood vessels, resisting fatigue, slowing down heart rate and blood pressure at both poles, promoting the biosynthesis of DNA, protein and lipids, quenching thirst, promoting fluid production, expelling pus, relieving swelling, relieving sore throat and pain, and relieving fever and pain.
4. Total flavonoids: the content of total flavonoids in camellia. 4400mg/kg, has the functions of dilating coronary vessels, reducing hypertension, enhancing cardiac contraction, reducing heartbeat, quenching thirst and eliminating phlegm, resisting bacteria and inflammation, resisting capillary fragility and abnormal permeability, resisting tumor, protecting liver and gallbladder, relieving diarrhea, relieving spasm, ovum hormone, relieving fever and pain, reducing cholesterol and diuresis.
5, tea pigment: Camellia is rich in tea pigment, reducing blood sugar, urine sugar, blood lipid, glycosylated hemoglobin, reducing insulin resistance, improving hemorheology, alleviating microcirculation disorders. Lowering cholesterol and triglycerides and increasing high density lipoprotein can prevent and treat diabetic complications, such as cardiovascular and cerebrovascular diseases and atherosclerosis.
Camellia is a rare plant in the world. It is the only camellia with golden petals in nature. It has the reputation of "Giant Panda", "Queen of Camellia" and "Oriental God Tea".
7. Camellia chrysantha is a unique flower in China, which mainly grows in Fangcheng District, Fangchenggang City, Guangxi, and is a branch of Lanshan Mountain. Therefore, Fangcheng District is known as the "hometown of golden camellia", where more than 95% of the wild golden camellia in the world is distributed. In 2009, the State Forestry Administration awarded Fangcheng District the title of "Hometown of Golden Camellia in China".
Camellia chrysantha is one of the eight first-class protected plants in China, and its flower is named "city flower" in Fangchenggang. 1986 Guangxi established a provincial camellia nature reserve in Fangcheng district. 1994 was upgraded to a national nature reserve with the approval of the State Council, namely Fangcheng camellia national nature reserve in Guangxi, and the only camellia gene bank in the world was established in the reserve.
9. Camellia has not only high ornamental value, but also high economic value and special health care function for human body, and its industrial development prospect is broad. At present, the manufacturer has developed and produced several products such as camellia tea, concentrated solution and oral liquid. , exported to Europe, America and Southeast Asia.
