Prepare each herb separately, in its own jar. Combine them in small batches as you use it. (Student's Manual, Basic Course, p. 25) Cho's recipe uses a 20 L jar for each herb. (Cho, Recipe, p. 24) His herbs are angelica root, cinnamon bark, licorice root, garlic and ginger. (Cho, Recipe, p. 24)
- Fill the jars of dried herbs halfway with rice wine or beer. (Student's Manual, Basic Course, p. 25)
- Fill all six jars nearly to the top with vodka or other alcohol. (Student's Manual, Basic Course, p. 25)
- Stir every early morning for 2 weeks, then filter and store the extract. (Cho, Recipe, p. 28)
The fact sheet warns that OHN must be stirred daily. It also says the herbs cost less if you order them in bulk. (Student's Manual, Basic Course, p. 21) Drake says it takes a case of vodka to make his OHN. (Office Hours Ep. 18, 1:19:01)
Blend the six extracts just before use, at 2 parts angelica to 1 part each of the rest. (Cho, Recipe, p. 29)
The blocks here give no herb weights for a bulk batch.
