I had been using this at bedtime to attempt improve sleep quality - possibly somewhat helpful, possibly not. Nothing remarkable at any rate, at a dose of 15 pills. (I'm using other tonic formulae during the day.) One night, decided to dissolve these pills in water for a more pronounced effect. I was surprised that there was no sweet component to the taste at all that I could detect, in spite of the fact that the formula contains a number of sweet-tasting herbs: Astragalus, Codonopsis, Longan, Baked Licorice, and Red Date. Also, Tang-Kuei has a particular taste that stands out, and this was not noted. So I would not consider using this version where tonifying deficiency was a desirable property. And frankly, I wondered if the contents matched the description.
As a matter of comparison, I prepared Gui Pi Tang from single 5:1 extracts. A different taste entirely.

Disadvantages: May not contain what it says it does.
