Problems solved by technology

[0005] There is no instant tea made of fulvic acid as the main raw material in the market now, and the medical efficacy of fulvic acid has not been fully utilized. There are many patents on instant tea, and there are also many instant teas used for health care and treatment. Basically, Add Chinese herbal medicine to achieve the purpose; such as Liuwei bone strengthening instant tea, the formula is lotus seeds, yam, black snake, papaya, mulberry leaves, calcium carbonate, green tea, suitable for middle-aged and elderly people with bone problems caused by wind, cold, damp or calcium deficiency. Loose mass, weak waist and knees, arthralgia due to wind-cold and dampness, muscle and bone pain, frozen shoulder, cervical spondylosis, lumbar muscle strain, sciatica, lumbar disc herniation, back and limb joint pain, etc. Complicated, unstable quality Disadvantages
