Frequently Asked Questions

  • What are the recommended doses for the concentrated granules of single herb and base formula?

    The recommended dose for each single herb varies, and the dose for each formula varies too.  In Taiwan, the TCM doctors would use one or multiple base formula plus specific single herbs according to patient’s symptoms. They don’t use only just single herbs to make the prescriptions, because the base formula granule is produced by cooking all the herb ingredients together and there can be additional synergistic function among the herbs that make the formula more effective.  In general, the daily dose prescribed range is from 9 – 12 grams per day.

    The recommended general dosage for both formulas and single herb granules are listed on the SUNTEN formula book.  For example: suggested daily dose for Jia Wei Xiao Yao San (Bupleurum & Peony Formula) is 12 grams per day, and for Huang Qin (Scute) is 0.4-1.8 grams daily.
