How is your health? Do you get heaty easily?
Generally, huai san, yu zhu & ji zi are very safe. Put some dry
dates to make it taste sweet. It's good for the blood, but dun put
too much as it can be heaty.
If you have back problem, put in du zhong also.
If you want good digestion, use lian zi and bai he. It's good for
ppl who always have gastric problems.
