Sanjiu herbal extract powders are easy to use. You can use single herbs or make a complex formula with the individual herb packets. All you have to do is choose the herb or herbs you want to make into a tea. Empty them into a cup, add hot water, stir, and drink. Depending on the concentration of the formula you can put them into 1-3 cups of water. If you use three cups of water you would drink one cup three times a day.
