Lycium barbarum, Astragalus membranaceus, Polygonatum sibiricum and American ginseng are all good health-preserving drugs, and the "four-thing tea" brewed by combining them has a good effect. Moreover, the brewing method and dosage of this "four-thing tea" are very simple.

Ingredients: Radix Astragali 8g, Rhizoma Polygonati 10g, Fructus Lycii 5g, and Radix Panacis Quinquefolii 8g. Note that these four herbs are top grade, and the dosage should be controlled within 10g each time.

Practice: Put Lycium barbarum, Astragalus membranaceus, Polygonatum sibiricum and Panax quinquefolium directly into a teacup, pour it into boiling water and soak it for half an hour, then you can drink it directly.

Persistence is the key to health care. Lycium barbarum, Astragalus membranaceus, Polygonatum sibiricum and American ginseng should be drunk for a long time. Also note that if you catch a cold at four o'clock, don't drink it.
