Older people generally have problems with high blood pressure or blood lipids, and their digestion is not very good. You can buy some Gynostemma pentaphyllum and drink it with Lycium barbarum to keep fit and have an effect on blood lipid and blood pressure. You can also drink cassia seed oatmeal tea, which is not the "tea" we usually drink. Does not involve tea polyphenols, will not affect sleep, health care is not expensive. You can drink it all year round!
