Besunyen Changrun tea is usually drunk once a day, and a packet is brewed once within half an hour after lunch or dinner, and then drunk once, without repeated brewing. You can also increase or decrease the amount according to your own situation. If it's the first time to drink, I suggest drinking a pack. If constipation is serious, you can brew two packs together. Coffee is cold, so is Changrun tea. It is recommended not to drink at the same time, so as not to stimulate the stomach.
