I recall a drink that was quite helpful to me. That is the 黄芪，红枣，枸杞子茶。 But just a word of caution. I am no TCM doctor, but I know this drink is quite mild like chrysanthemum tea, but nevertheless still has herbs. So it is good to test it out in smaller portions.
Ingredients:
15 g Huang Qi (Astralagus Root) ,
20 g Wolfberries (Gou Qi zi) ,
20 g Dried Red Dates (Hulled),
2-6 cups of water (Depending on taste)
Method:
1. Weigh and wash all the ingredients.
2. Put all the washed herbs and water into a pot (preferably clay)
3. Bring to a boil. Boil for another 5 minutes, off the flame and let the herbs seep in hot water.
4. Let it cool down a little before drinking.
5. If you want you can add more water or up the portion and store in the fridge.
Notes:
1. The tea is said to improve immunity.
2. I am not sure why you need to remove the hull of the red dates, but I have come across some literature that says that the hull is better removed to prevent dampness and heatiness, so I have always used hulled red dates.
3. I tend to add more water as my kids tend to prefer it diluted, and also because I use it to replace drinking water.
